Electric bike locks need to balance theft resistance with the weight and reach you can manage on a daily ride. My best overall pick is the Kryptonite Parkview Folding Bike Lock, a folding design that offers a different carrying and locking setup from the many U-lock-and-cable kits in this roundup. For a more familiar format, the Sportneer Heavy-Duty Bike U-Lock with 5 ft Security Cable pairs a rigid lock with extra reach, while the NDakter 5-Digit Resettable Combination Bike Chain Lock skips keys. The main tradeoffs are portability versus locking flexibility, and convenience versus how much protection a lock’s construction can provide. Read on for a comparison of all 15 options and guidance on choosing a lock that fits your bike, parking routine, and risk level.

Key Takeaways
- The roundup favors different locking formats for different routines: the Kryptonite Parkview folding design stands apart from the U-lock-and-cable sets, while chain options can wrap around awkward parking points.
- Several U-lock kits add a 5- or 6-foot cable, but the cable is best treated as a way to secure a wheel or extend reach, not as a substitute for the main lock.
- Combination access is the clearest convenience split: NDakter, Sportneer, Febabilo, and Master Lock offer combination options, while key-based picks avoid remembering a code.
- Chain length changes where you can lock up: the 3-foot Titanker and 2.72-foot Weogine are more limited in reach than the 6-foot Master Lock cable or longer cable add-ons.
- The list includes several similar U-lock-and-cable configurations, so buyers should compare access method, cable length, and included hardware rather than assuming the shared format means identical fit or security.

More Details on Our Top Picks
Titanker Heavy-Duty Bicycle Chain Lock with Keys, 3 Feet, 6 mm
The Titanker 3-foot chain is a straightforward pick for riders who want a flexible, keyed lock without a combination to remember. Its 6 mm alloy steel links and cloth sleeve suit quick stops where you need to loop around a rack or secure more than one type of item. The keyhole dust cover adds a small layer of protection from rain and grit, while the chain locks by snapping together without requiring a key. Compared with the NDakter 5-Digit Combination Chain Lock, Titanker avoids forgotten-code hassles but makes you carry a key. Its three-foot reach is also less adaptable than NDakter’s longer listed length options. The manufacturer cautions against leaving a bike unattended for extended periods, especially in high-crime areas, so I’d treat this as a practical everyday deterrent rather than a long-duration security solution.
Pros:- 6 mm alloy steel chain offers flexible attachment around racks and other objects.
- Cloth sleeve helps reduce frame scratches and protect the chain.
- Keyhole dust cover helps keep rain and debris away from the cylinder.
- Snaps closed without needing a key and includes two keys.
Cons:- A key must be carried and kept track of.
- Three-foot length offers less reach than longer chain options.
- Manufacturer advises against extended unattended parking, particularly in high-crime areas.
Best for: Riders making brief stops who prefer a keyed chain and need a flexible lock for a bike or other everyday equipment.
Not ideal for: Commuters who want keyless access, need extra reach, or leave an e-bike parked outside for long periods in a high-risk area.
- Brand:Titanker
- Lock type:Key lock
- Chain length:3 feet
- Chain link thickness:6 mm
- Material:Alloy steel
- Weight:1.4 pounds
- Included:Chain lock and 2 keys
Our verdict“Choose the Titanker for brief stops when you want a simple keyed chain, not extended high-risk parking security.”
NDakter 5-Digit Resettable Combination Bike Chain Lock
For riders who would rather remember a code than carry keys, the NDakter 5-Digit Combination Chain Lock offers a flexible chain format with a resettable combination. Its 6 mm alloy steel chain has a polypropylene sleeve to help protect paint, and the listed 3.2-foot length suits ordinary rack stops. Multiple length options make this a more adaptable chain choice than the fixed 3-foot Titanker keyed chain; the tradeoff is a combination cylinder instead of the Titanker’s key mechanism. The five-digit code provides more possible combinations than the four-digit setup on the Febabilo U-lock, but a forgotten code can leave you unable to open it. Check wheel clearance before buying: the chain may not pass through gaps under 1.25 inches. Its stated limitations also make it a poor match for prolonged parking in high-crime areas.
Pros:- Resettable five-digit combination eliminates the need to carry a key.
- Alloy steel chain has a sleeve to help prevent scratches to the bike frame.
- Several length options allow buyers to match the chain to their parking setup.
- Can also secure scooters, motorcycles, gates, and other equipment.
Cons:- May not fit through wheel gaps smaller than 1.25 inches.
- A forgotten combination can prevent access to the lock.
- Not recommended for extended unattended use in high-crime areas.
Best for: Riders who want a keyless chain for routine stops and value choosing from several chain lengths.
Not ideal for: People who may forget a combination, need to thread a lock through narrow wheel gaps, or park unattended for long periods in high-risk locations.
- Brand:NDakter
- Lock type:5-digit resettable combination
- Default combination:00000
- Listed length:3.2 feet
- Length options:2.62, 3.2, 4.27, 5, or 6 feet
- Chain thickness:0.24 inches (6 mm)
- Chain material:Alloy steel
- Weight:About 1.45 pounds
Our verdict“Pick the NDakter chain if keyless flexibility matters more to you than the straightforward key access of the Titanker.”
Febabilo 4-Digit Combination Bike U-Lock with 5-Foot Steel Cable
The Febabilo U-lock and 5-foot cable suit riders who want a rigid main lock plus extra reach for a second wheel or nearby equipment. Its hardened steel shackle is the more structured format compared with the flexible chains from Titanker and NDakter, while the cable helps cover parts a U-lock may not reach on its own. The combination is resettable and keyless, though four digits mean a shorter code than the NDakter chain’s five-digit dial. A PVC coating helps limit scratches, and the lock can be used without the cable when a lighter setup is preferable. The tradeoffs are practical: this model is described as heavy, and no bike mount is included, so carrying it may require a bag or another solution. I’d choose it for riders who want bundled wheel coverage, not those prioritizing compact carry.
Pros:- Hardened steel shackle provides a rigid locking point.
- Included five-foot cable extends reach for a wheel or additional item.
- Resettable combination allows keyless access.
- PVC coating helps protect the bike finish from scratches.
Cons:- Described as heavy, which may be inconvenient to carry on every ride.
- No bike mounting bracket is included.
- Four-digit combination is shorter than the NDakter chain’s five-digit code.
Best for: E-bike and scooter owners who want a keyless U-lock with a cable for securing a wheel or additional item.
Not ideal for: Riders who need a supplied frame mount, want a light everyday carry, or prefer a longer combination code.
- Brand:Febabilo
- Lock type:4-digit resettable combination U-lock
- Initial combination:0000
- Shackle thickness:0.57 inches
- Interior dimensions:7.5 × 4.5 inches
- Exterior dimensions:9.8 × 7 inches
- Cable length:5 feet
- Cable thickness:0.47 inches
- Included components:Combination U-lock and cable
Our verdict“Choose the Febabilo set if you want a keyless U-lock and cable together and can accommodate the added carry weight.”
Sportneer Heavy-Duty Bike U-Lock with 5 ft Security Cable
The Sportneer Heavy-Duty U-lock is the most ready-to-carry option here: it pairs a 17 mm alloy steel shackle with a five-foot cable, two keys, and a mounting bracket. That package makes it a more convenient fit for regular riders than the Febabilo U-lock, which also includes a cable but lacks a mount. The bracket is designed for tubes under 26 mm to 38 mm in diameter, so checking your frame before purchase matters. A silicone-coated body helps limit scratches and exposure to dirt or moisture, while the cable extends locking reach for a wheel or another item. At 1.64 pounds, it still adds noticeable weight, and its fixed U-lock shape is less adaptable around unusual parking fixtures than either chain option. The stated hydraulic shear resistance is a manufacturer specification, not a guarantee against every theft method.
Pros:- 17 mm alloy steel shackle forms a substantial rigid locking point.
- Five-foot cable adds reach for a wheel or additional equipment.
- Mounting bracket and two keys are included.
- Silicone coating helps guard the bike finish and lock body from dirt and moisture.
Cons:- At 1.64 pounds, it may feel bulky for riders minimizing carried weight.
- Bracket fit depends on the bike tube measuring within the stated compatibility range.
- U-lock geometry is less flexible than a chain for awkward parking setups.
Best for: Regular commuters with a compatible frame tube who want a keyed U-lock, included cable, and on-bike mounting bracket.
Not ideal for: Weight-conscious riders, owners whose frame does not fit the bracket range, or anyone needing a chain’s flexibility around oversized fixtures.
- Dimensions:7.76 × 5.02 inches
- Shackle thickness:17 mm (0.67 inches)
- Weight:1.64 pounds
- Cable length:5 feet
- Lock core:Zinc alloy
- Lock head:Alloy steel
- Included accessories:Mounting bracket and 2 keys
- Bracket tube compatibility:Under 26 mm to 38 mm diameter
- Stated hydraulic shear resistance:Up to 12 tons
Our verdict“Choose Sportneer if you want a mounted, keyed U-lock-and-cable package and your bike fits the bracket.”
Kryptonite Parkview Folding Bike Lock, 88.4 cm
The Kryptonite Parkview is the folding choice for riders who value a compact carrying format over a chain’s flexibility or a U-lock’s included cable. Its 88.4 cm locking length gives more routing options than a compact rigid shackle, while the transport bracket keeps the folded lock attached to the bike. Hardened steel bars and tightened rivets are designed to resist cutting, and the set includes two keys. Compared with the Sportneer U-lock, Parkview skips the separate five-foot cable but folds for storage rather than relying on a fixed U shape. That convenience comes with a weight penalty: at 2.15 pounds, it is heavier than Sportneer’s 1.64-pound lock. The stated intended use is short stops in low- to medium-risk areas, so I would not make it my pick for extended parking where theft risk is high.
Pros:- Folding design and transport bracket support on-bike carrying.
- 88.4 cm locking length offers routing flexibility.
- Hardened steel bars and tightened rivets are designed for cut resistance.
- Includes two keys and is listed as weather resistant.
Cons:- Weighs 2.15 pounds, more than the Sportneer U-lock in this lineup.
- Does not include a separate security cable.
- Intended for short stops and low- to medium-risk areas rather than prolonged high-risk parking.
Best for: Riders who want a foldable lock with a transport bracket for short stops in low- to medium-risk areas.
Not ideal for: People who need a lighter lock, a separate cable for securing another wheel, or a choice suited to prolonged parking in high-risk areas.
- Material:Alloy steel
- Bar thickness:3 mm
- Locking length:88.4 cm (2.9 feet)
- Weight:2.15 pounds (0.97 kg)
- Lock type:Pin tumbler
- Weather resistant:Yes
- Included components:Bike lock, 2 keys, and transport bracket
Our verdict“Pick Parkview if folding portability matters more than low weight or a bundled cable, and your stops are brief.”
Sportneer Heavy-Duty Bike U-Lock with 5-Foot Steel Cable
I’d put this Sportneer first for riders who want a keyed U-lock and a secondary cable in one portable set. Its 17 mm shackle is thicker than the NDakter combination U-lock’s 14.6 mm shackle, while the included 5-foot cable gives extra reach for a wheel or accessory that the U-lock alone may not capture. The mounting bracket also makes it easier to carry than the heavier NDakter set, though it only fits bike tubes measuring 26–38 mm. The silicone-coated body can help guard against grime and moisture, but the stated resistance to hydraulic shear is product-provided information, not independent security testing. I’d choose it for routine stops, not treat it as a guarantee against determined theft.
Pros:- 17 mm shackle is thicker than the NDakter combination U-lock’s 14.6 mm shackle
- Included 5-foot cable adds reach for a wheel or accessory
- Mounting bracket and two keys are included
- Silicone-coated body helps protect the lock from dirt and moisture
Cons:- Mounting bracket is limited to bike tubes 26–38 mm in diameter
- Security claims are not accompanied by independent testing details
- A cable adds flexibility but should not be treated as equivalent to the U-lock’s main shackle
Best for: E-bike and bicycle owners who prefer keys, want to secure a frame and an additional wheel or accessory, and have a compatible 26–38 mm frame tube for the bracket.
Not ideal for: Riders whose frame tubes fall outside the bracket’s stated fit range, or anyone seeking independently verified resistance against targeted attacks.
- Lock type:Key lock
- Shackle thickness:17 mm (0.67 in)
- Lock dimensions:7.76 × 5.02 in
- Weight:1.64 lb
- Cable length:5 ft
- Bracket fit:Bike tubes 26–38 mm in diameter
- Keys included:2
- Hydraulic shear resistance:Claimed up to 12 tons
Our verdict“Choose this Sportneer if you want a bracket-mounted keyed U-lock with a useful secondary cable and your bike fits the bracket.”
NDakter 4-Digit Combination U-Lock with 5-Foot Steel Cable
For riders who would rather leave keys at home, this NDakter pairs a resettable 4-digit combination with a 14.6 mm hardened steel shackle and a 5-foot cable. The code-based setup is its clearest distinction from the keyed Sportneer U-lock: there’s no key to carry, but forgetting the combination can leave you stuck. Its large 7.5 × 4.5-inch interior can make it easier to reach a rack or frame than a tighter-fitting lock, while the cable helps cover a wheel or accessory. The tradeoff is carrying weight: the complete set weighs 2.82 lb, and it has no mounting bracket. Compared with the lighter Hapleby set, this is the more convenient choice for keyless access, but a less attractive one for daily carrying.
Pros:- Resettable 4-digit combination avoids carrying a key
- Hardened alloy steel shackle is 14.6 mm thick
- 5-foot cable can secure a wheel or accessory
- Large 7.5 × 4.5-inch interior offers useful locking room
Cons:- Combined U-lock and cable weight is 2.82 lb
- No mounting bracket is included
- A forgotten or exposed combination can undermine the convenience of keyless access
Best for: Commuters who want a resettable code instead of keys and need a roomy U-lock opening plus a cable for a second locking point.
Not ideal for: Weight-conscious riders or anyone who wants an included frame mount for carrying the lock on the bike.
- Lock type:Combination U-lock with steel cable
- Combination:Resettable 4-digit
- Shackle material:Hardened alloy steel
- Shackle thickness:14.6 mm (0.57 in)
- Interior dimensions:7.5 × 4.5 in
- Cable length:5 ft
- Combined weight:2.82 lb
- Mounting bracket:Not included
Our verdict“Pick the NDakter if keyless access and a roomy U-lock matter more to you than a lighter carry or included mount.”
Hapleby Bike U-Lock Set with 6-Foot Steel Cable
The Hapleby’s main advantage over the two 5-foot-cable U-lock sets here is simple: its 6-foot cable gives more room to loop through a wheel or accessory when the rack is awkwardly placed. The package also includes a keyed U-lock, mounting bracket, two keys, and straps, making it a practical kit for riders who want the carrying hardware included. Its listed 0.55-inch solid steel body and corrosion-resistant surface treatment suit everyday outdoor use, but the product data gives less detail about shackle performance than Sportneer’s stated 17 mm figure. There’s also a weight discrepancy: the description says 1.5 pounds, while the specifications list 1.18 kg. I’d favor it for reach and included accessories, not for buyers who need clear, consistent weight information.
Pros:- 6-foot cable is longer than the 5-foot cables supplied with the Sportneer and NDakter U-lock sets
- Includes a mounting bracket, two keys, and two straps
- Dust cover and corrosion-resistant surface treatment suit outdoor storage
- U-lock can be used on its own or alongside the cable
Cons:- Listed weight conflicts between 1.5 lb in the description and 1.18 kg in the specifications
- Shackle thickness and independent security-test details are not provided
- A cable adds reach but is not a substitute for the U-lock as the primary securing point
Best for: Bike owners who often need extra cable reach around a wheel or accessory and want a keyed set with a bracket and straps included.
Not ideal for: Riders comparing locks by precise carry weight or those who want detailed, independently supported security-performance claims.
- Lock type:Keyed U-lock
- U-lock material:0.55-inch solid steel
- Cable length:6 ft
- Item dimensions:7.3 × 4.7 × 1.18 in
- Weight listed in description:1.5 lb
- Weight listed in specifications:1.18 kg
- Included keys:2
- Other included components:Mounting bracket and 2 straps
Our verdict“Choose Hapleby if a longer cable and included mounting accessories matter more than consistent weight data or detailed security specifications.”
Sportneer 5-Digit Combination Bike Chain Lock
This Sportneer chain is the keyless alternative for riders who need more flexibility than a U-lock opening allows. Its resettable 5-digit code offers up to 100,000 possible combinations, while the chain can wrap around objects that may not fit inside the NDakter U-lock’s fixed 7.5 × 4.5-inch opening. The polypropylene cover helps protect bike paint, and a dustproof cap shields the lock head from debris and water. Those practical touches don’t change the main tradeoff: the 6 mm chain is more flexible to position, but it is not the same kind of rigid shackle as the 17 mm Sportneer U-lock. Length choices are also short at 3.2, 3.6, or 4 feet, and the 1.3-inch lock head may not pass through every frame or tire gap.
Pros:- Resettable 5-digit combination provides up to 100,000 possible codes
- Flexible chain can wrap around fixtures that may not fit inside a U-lock
- Polypropylene cover helps protect bike paint
- Dustproof cap helps shield the lock head from debris and water
Cons:- 6 mm chain does not offer the rigid shackle format of the Sportneer U-lock
- Available lengths of 3.2, 3.6, and 4 ft may limit what can be secured together
- 1.3-inch lock head may not fit through some tire or frame gaps
Best for: Riders who want keyless operation and a flexible chain for locking to varied fixtures, especially when a rigid U-lock cannot reach around the rack.
Not ideal for: Owners who need a long reach, a rigid U-lock-style shackle, or a lock head small enough to fit through narrow frame and tire gaps.
- Lock type:Resettable 5-digit combination chain lock
- Chain material:Manganese steel
- Chain thickness:6 mm (0.236 in)
- Available lengths:3.2 ft, 3.6 ft, and 4 ft
- Possible combinations:Up to 100,000
- Lock head diameter:1.3 in
- Cover material:Polypropylene
- Initial combination:00000
Our verdict“Choose this chain when keyless flexibility matters more than U-lock rigidity or extended reach.”
Weogine Heavy-Duty Bike Chain Lock with 3 Keys, 2.72 ft
At 349.83 g, the Weogine is the lightest-feeling carry option in this group by listed weight, but its 2.72-foot length and 4 mm chain make it a compact convenience lock rather than a flexible substitute for the longer, thicker Sportneer chain. The short length can work when the frame is close to a rack, yet it may not reach a second wheel or a bulky fixture. It uses a key instead of a combination, and the three included keys provide spares; the chain can also snap shut without inserting a key, although a key is still needed to unlock it. Its covered alloy-steel chain is suited to routine securing, but the 4 mm links offer limited resistance against determined cutting attempts.
Pros:- Listed weight is 349.83 g, lighter than the Sportneer 5-digit chain’s listed length options suggest for a longer chain format
- Includes three keys, reducing reliance on a single key
- Can snap shut without inserting a key
- Protective polypropylene fabric cover helps shield the chain and bike finish
Cons:- 4 mm chain offers limited resistance against determined cutting attempts
- 2.72-foot length restricts reach around large fixtures or multiple bike parts
- Requires a key to unlock, unlike the keyless Sportneer chain
Best for: Riders who want a light, short keyed chain for brief stops at nearby racks and value spare keys and quick snap-shut locking.
Not ideal for: E-bike owners leaving a bike for long periods in higher-risk locations, or anyone who needs enough chain length to secure multiple parts or reach a distant fixture.
- Lock type:Key lock
- Chain length:2.72 ft
- Chain thickness:4 mm
- Chain material:Alloy steel
- Cylinder material:Zinc alloy
- Included keys:3
- Item weight:349.83 g
- Warranty:1 year
Our verdict“Choose Weogine for a light, compact keyed chain at close-fitting racks, but skip it when reach or stronger cut resistance is the priority.”
Honszex Heavy-Duty Scooter and Bike Chain Lock, 36.2 in
The Honszex chain lock is the flexible pick for riders who also need to secure a scooter, stroller, or other mobility gear. Its rubber cover can help limit frame scratches, while the fabric-wrapped chain is designed to cut down on rattling and contact noise. Compared with the Master Lock 8122D cable, this chain is a more substantial-feeling format, though neither listing supplies a security rating to guide high-risk parking decisions. Pay attention to the measurements: the lock is 36.2 inches overall, but the stated chain section is only 23.6 inches, which may limit reach around wide posts or multiple items. No weight is listed, so portability is hard to judge. I’d choose it for flexible, lower-exposure stops, not as a documented high-security solution.
Pros:- Designed for bicycles, e-bikes, scooters, motorcycles, and other mobility equipment
- Rubber cover helps protect finishes and gives the chain a grippy surface
- Fabric wrapping is intended to reduce chain noise and contact with the frame
Cons:- The stated chain length is 23.6 inches, shorter than the 36.2-inch overall length
- No weight or security rating is provided in the product information
Best for: E-bike and scooter owners who want one covered chain for several types of mobility equipment and usually lock near compact racks or posts.
Not ideal for: Riders who need a verified security rating, a long usable chain reach, or a known carry weight before choosing a lock.
- Material:Alloy steel and rubber
- Total length:36.2 in (92 cm)
- Chain length:23.6 in (60 cm)
- Chain diameter:0.23 in (0.6 cm)
- Color:Black
- Model:HZX-BL001
Our verdict“Choose the Honszex if you want a covered chain for varied mobility gear, but skip it if reach and documented theft resistance are priorities.”
NDakter Heavy-Duty Bike U-Lock with 5-Foot Cable
This NDakter pairs a resettable 4-digit U-lock with a five-foot cable, making it a practical choice for riders who want a keyed-free daily routine and a way to loop through an extra wheel or accessory. Its 0.7-inch U-bar is a sturdier core format than the Master Lock 8122D cable, which is positioned for basic deterrence, while the cable adds reach the rigid shackle cannot provide alone. The combination has 10,000 possible codes, and two included keys can retrieve a forgotten code; they do not unlock the lock, so they are not a backup way in. At 3.05 pounds for the set, it also asks more of your commute than a single cable lock. I’d favor it for moderate-risk stops where the added U-lock structure is worth carrying.
Pros:- Resettable 4-digit combination offers keyless everyday access
- Five-foot steel cable adds reach for a wheel or accessory
- PVC-coated shackle helps reduce scratches and exposure to moisture
- Suitable for bicycles, e-bikes, and scooters
Cons:- The U-lock and cable weigh 3.05 pounds together
- Included keys retrieve a forgotten code but cannot unlock the lock
Best for: Commuters who prefer a combination lock, want to secure a wheel alongside the frame, and can carry a 3.05-pound lock-and-cable set.
Not ideal for: Minimalist riders seeking a lightweight lock, or anyone who expects the included keys to open the lock if the combination is forgotten.
- Lock type:Resettable 4-digit combination U-lock
- Combination options:10,000
- Included cable:5 ft steel cable
- Total weight:3.05 lb
- U-lock weight:2.1 lb
- U-bar thickness:0.7 in
- Cable thickness:0.47 in
- Internal lock size:5.9 × 4.7 in
- External lock size:8.4 × 7.1 in
Our verdict“Pick this NDakter set if you want a combination-operated U-lock with cable reach and accept the extra carry weight.”
Master Lock 8122D 6 ft Cable Bike Lock, 4-Digit Combination, 1/2 in Diameter
The Master Lock 8122D is the straightforward choice when reach and keyless convenience matter more than resistance to determined theft. Its six-foot braided-steel cable can loop around racks that are awkward for a compact U-lock, and the resettable combination means there is no key to carry. That flexibility also defines its limitation: the listing describes it as basic security and theft deterrence, and a cable is easier to cut than the hardened shackles on the NDakter 18 mm U-lock or Corki U-lock. Vinyl coating helps protect paint and gear, but it does not change the cable’s security role. I’d use this for brief stops in lower-risk areas or as a secondary lock, rather than as the only protection for an expensive e-bike left unattended for long periods.
Pros:- Six-foot cable reaches racks and anchor points that may not fit a compact shackle
- Resettable 4-digit combination avoids carrying a key
- Vinyl coating helps prevent scratches to bike frames and outdoor gear
- Limited lifetime warranty is listed
Cons:- Cable construction is easier to cut than the U-locks in this lineup
- Product information positions it for basic deterrence rather than high-security parking
Best for: E-bike owners making brief, lower-risk stops who value a long reach and do not want to carry keys.
Not ideal for: Riders who leave a valuable e-bike parked for extended periods in exposed locations and need a more resistant primary lock.
- Lock type:Combination cable lock
- Cable length:6 ft (1.8 m)
- Cable diameter:1/2 in (13 mm)
- Material:Braided steel with vinyl coating
- Combination:Resettable 4-digit
- Model:8122D
- Warranty:Limited lifetime warranty
Our verdict“Choose the Master Lock for convenient reach at brief, lower-risk stops, not as your sole lock for a high-value e-bike in a theft-prone area.”
NDakter Heavy-Duty Bike U-Lock with 6 ft Security Cable and 3 Keys
For riders who put a substantial shackle ahead of low carry weight, this NDakter combines an 18 mm hardened steel shackle with a double deadbolt and six-foot cable. That makes it a more security-focused format than the Master Lock 8122D, whose cable is intended for basic deterrence; the extra cable here can secure a wheel, but it should not be mistaken for the U-lock’s main protective element. Three keys provide spares, while the dust cover and silicone coating help shield the cylinder and reduce frame contact. The tradeoff is clear: the set weighs 3.4 pounds, and there is no mounting bracket included, so carrying it may take planning. I’d choose it for regular urban parking where a keyed, substantial shackle is preferable to a lighter, more flexible lock.
Pros:- 18 mm hardened steel shackle with a double deadbolt locking system
- Six-foot steel cable adds reach for securing a wheel or equipment
- Three keys provide spares for different carry or storage locations
- Dust cover and silicone coating help protect the cylinder and bike finish
Cons:- At 3.4 pounds, it is a heavy option for daily carry
- Mounting bracket is not included
Best for: E-bike commuters who park regularly at public racks, prefer a keyed lock, and can accommodate a heavier lock in a bag or pannier.
Not ideal for: Riders prioritizing low weight or a ready-to-use frame mount, and those whose frame or rack cannot fit the listed inner dimensions.
- Lock type:U-lock
- Shackle diameter:18 mm
- Outer dimensions:7.8 × 9.2 in
- Inner dimensions:5.5 × 7 in
- Weight:3.4 lb
- Cable:6 ft × 0.4 in steel
- Keys included:3
- Locking system:Double deadbolt
- Mounting bracket:Not included
Our verdict“Pick this NDakter if you want a substantial keyed shackle and cable for regular public parking and are willing to carry the weight.”
Corki Heavy-Duty Bike U-Lock with 5-Foot Cable
The Corki stands out for combining a 17 mm hardened alloy-steel shackle and five-foot cable in a listed weight of 1.64 pounds, making it much easier to carry than the 3.4-pound NDakter 18 mm U-lock. It also includes two keys and a frame bracket, so riders with compatible tubing have a convenient way to keep the lock on the bike rather than in a bag. The silicone sleeve can reduce rattling and protect the frame, while the cable adds flexibility for a wheel. Its lighter weight is the main draw, but buyers should not read the stated shear resistance of up to 12 tons as independently verified: the product data supplies no independent substantiation. The bracket only fits frame tubes from 26 to 38 mm. I’d select it for routine commuting when carry comfort matters alongside a U-lock format.
Pros:- Listed weight of 1.64 pounds is lower than the other U-lock sets in this batch
- 17 mm hardened alloy-steel shackle is paired with a five-foot cable
- Silicone sleeve helps protect the frame and reduce rattling
- Includes two keys and a mounting bracket for compatible frame tubes
Cons:- Mounting bracket only fits frame tubes measuring 26–38 mm
- The stated shear resistance is not independently verified in the product information
Best for: Daily e-bike commuters who want a lighter U-lock kit with a frame bracket and have compatible 26–38 mm tubing.
Not ideal for: Riders whose frames fall outside the bracket’s fit range, or buyers who require independently verified performance claims.
- Lock type:U-lock
- Shackle material:Hardened alloy steel
- Shackle diameter:17 mm (0.67 in)
- Stated shear resistance:Up to 12 tons
- Weight:1.64 lb
- Cable:5 ft braided steel with PVC coating
- Core material:Zinc alloy
- Frame tube compatibility:26–38 mm (1.02–1.5 in)
- Included components:2 keys and installation bracket
Our verdict“Choose the Corki for a lighter, mountable U-lock-and-cable kit if your frame fits the bracket and you are comfortable treating the shear claim as unverified.”
How We Picked
I ranked these electric bike locks around the choices an e-bike owner actually faces: whether a lock can secure the frame to a fixed object, how much reach its chain or included cable adds, and whether keys or a combination suit the rider’s routine. I also considered carrying practicality, the usefulness of included accessories, and how clearly each format serves a distinct need. A cable’s length can improve positioning, but I did not treat a cable as equal protection to a substantial primary lock.
The ordering reflects versatility and useful differentiation, not a claim that every product has been independently tested or that similarly named models have identical specifications. The Parkview leads for its distinct folding format; U-lock-and-cable sets follow for riders seeking a rigid primary lock with added reach; chains and standalone cables rank according to their fit for flexible parking, convenience, or secondary use. Buyers should confirm dimensions, mounting details, and the exact included components for the model they select.
Factors to Consider When Choosing Electric Bike Locks
Choosing among these locks is less about finding one format that suits every e-bike and more about matching the lock to how and where you leave yours. I’d start with the parking point and theft exposure, then check how much weight and setup effort I’m willing to carry each day.
Match the lock format to your parking spot
Before choosing a lock, check what you can actually secure your bike to at your usual stops. A U-lock needs a suitable fixed object and enough clearance around the frame; a chain can be easier to route around larger or awkward fixtures. Folding locks offer another shape and carrying arrangement, but their reach still needs to fit your parking setup. A common mistake is buying based on the bike alone and discovering that the lock cannot pass around the rack and frame together. Measure the likely locking point, including the frame area you intend to secure, before picking a format.
Treat cables as secondary reach, not a second primary lock
An included cable can help capture a front wheel or connect more parts of the bike to the same locking point. Its extra reach may solve a real fit problem, especially where the U-lock alone cannot reach both frame and wheel. That convenience does not make a cable interchangeable with the main lock: use the primary lock to secure the frame, and regard the cable as an added layer. Buyers often overestimate what a long cable contributes because length is easy to compare while construction and locking design are less visible. If the bike will be left for long periods in a high-risk location, prioritize the primary locking mechanism rather than choosing by cable length alone.
Choose keys or a combination around your habits
A key lock avoids the need to recall a code, but you need a safe way to carry and keep track of its keys. A combination lock removes that key-management task and can be convenient when multiple riders share a bike, though forgetting or mis-setting a code can delay departure. Think about gloves, low light, and whether you regularly lend the bike before deciding. Do not assume that more digits automatically make a lock a better fit; access convenience and the lock’s overall construction matter too. Pick the method you can use consistently, since a lock that is awkward to operate is more likely to be left behind.
Balance security with the weight you will carry
A lock that stays at home provides no protection at the rack. Chains and heavier-looking rigid designs can offer useful locking options, but their bulk may be inconvenient on a lightweight commuter setup. Compact carrying and easy mounting can matter more to a rider making short trips than maximum flexibility, while someone parking outside for hours may accept more weight for a stronger primary lock. Check whether the lock includes a mounting solution and whether it suits your frame layout. Avoid choosing solely by a “heavy-duty” label; compare the actual format, dimensions, and practical carrying burden.
Plan for the whole bike, not just the frame
E-bikes can have removable batteries, valuable displays, and accessories that are easy to take off. A frame lock cannot secure every component, so decide which parts you will remove or protect separately when parking. Check whether your battery can be removed quickly and whether the display detaches without tools. A frequent oversight is securing the frame and rear wheel while leaving an easily removable battery exposed. Your locking routine should account for the bike’s most valuable detachable parts, not just the main frame.
Spend more for a real change in your use case
Paying more makes sense when it buys a format, reach, or carrying feature that solves a specific problem in your routine. A folding design may suit someone who wants a different balance of storage and positioning; a longer chain or cable can help with a fixed, awkward rack. Extra length alone is not a reason to expect stronger theft protection, and an accessory cable should not be mistaken for an upgrade to the primary lock. Compare what the added feature lets you do, then weigh that against added bulk and setup time. If your parking needs are simple, a straightforward lock you carry every ride may be the more practical choice.
Frequently Asked Questions
Can I use one of these locks to secure an electric bike overnight?
For an overnight stop, first check whether the lock’s primary mechanism can secure the frame to a fixed object; an accessory cable alone is not a suitable substitute. These products differ in format and included reach, but the product names and listed accessories do not establish a uniform security level. If the location has elevated theft risk, consider using a second independent primary lock and remove the battery or other detachable valuables. Also choose a parking spot with good visibility and a solid rack. The right setup depends on the bike, location, and how long it will be unattended.
Is an included cable enough to secure both wheels and the frame?
It depends on the cable length, the size of the rack, and the way your frame is shaped. In this lineup, some U-lock kits include a 5-foot cable and others list a 6-foot cable, while the chain options have their own lengths and routing limits. A cable can add reach for a wheel, but it should not replace the main lock’s role in securing the frame. Try the intended route before relying on it, especially with large tires or a bulky e-bike frame. If the cable cannot reach all the parts you want to secure, remove a wheel or use another lock rather than forcing an awkward setup.
Should I choose a chain, U-lock, or folding lock for a heavy e-bike?
Start with where you park rather than the bike’s weight alone. A U-lock suits a rack with enough room for the lock to pass around the frame and a fixed object; a chain can be more adaptable around unusual fixtures, while a folding lock offers a different storage and reach profile. Carrying comfort matters because a bulky lock can be a nuisance on a heavy bike that is already less convenient to move. Check whether the lock can be mounted securely or carried without interfering with the battery, cables, or other equipment. Choose the format that you can use at your regular stops without leaving parts of the bike unsecured.
Are combination locks a better choice if I share my e-bike?
A combination lock can make sharing easier because riders do not need to hand off a physical key, and several options here use resettable or multi-digit combinations. That convenience only helps if every rider can use the code reliably and knows how to keep it private. A key-based lock may be simpler for a small group with a clear key handoff routine. Agree on one code-management method, and avoid writing the combination where it is stored with the bike. The choice comes down to how your group handles access, not the number of riders alone.
How can I tell whether the listed lock length will reach my rack?
Measure the route the lock must take around the rack and the part of the bike you want to secure, rather than estimating from the rack’s width. Allow room for the lock body, the frame’s shape, and the angle at which you can position the bike. The roundup includes short chains around three feet and cable options reaching five or six feet, but those measurements do not guarantee a fit for every parking point. Check the exact dimensions for the model and configuration you plan to buy, particularly where similar names describe different lengths or included parts. If possible, test the route with a cord before choosing.
Conclusion
For the best overall, I’d start with the Kryptonite Parkview Folding Bike Lock because its folding format gives this roundup a distinct alternative to the many cable-equipped U-locks. For best value, compare the NDakter 5-Digit Resettable Combination Bike Chain Lock with the Sportneer 5-Digit Combination Bike Chain Lock based on the chain length and access style that suit your parking routine. The best premium fit is the Parkview for riders who want a folding option, while anyone prioritizing ease of access may prefer a combination model as the best choice for beginners. For specific needs, pick a U-lock-and-cable set when you want a rigid primary lock with added wheel reach, a longer chain or cable when your rack is awkwardly placed, or the Master Lock 8122D when a standalone cable best fits a secondary-use role. Before deciding, verify the exact dimensions and included hardware for your chosen model, then select the lock you can carry and use every ride.
