NDakter Bike Locks Heavy Duty U Lock and Cable - Secure E-bikes

In this review of the NDakter Bike Locks heavy duty anti theft kit, the bottom line is simple: it is best for riders who want a robust, combined U-lock and cable solution to secure larger electric bikes, scooters, or multiple bicycles. The reviewer found the 18mm hardened steel shackle and an approximately 6ft steel cable work together to deter common theft methods; the kit's double-deadbolt design and three brass keys make everyday use straightforward. For anyone prioritizing real physical security over ultralight portability, this is a practical, value-oriented choice.

Key Features

• 18mm hardened shackle: The thick 0.7in steel U-shape provides higher resistance to cutting and leverage attacks than slimmer locks.
• 6ft steel cable: The long 6ft cable complements the U-lock to secure wheels, frames and additional bikes or accessories at once.
• Double deadbolt design: The ergonomic U-lock locks at two points for better pry resistance and stable engagement.
• Zinc alloy cylinder with dust cover: The precision-made lock cylinder reduces the chance of blockage and keeps the mechanism working in outdoor conditions.
• Three brass keys included: Supplying three sturdy keys makes it easy to keep spares at home and work to avoid lockouts.
• Generous interior space: With internal dimensions of about 5.5in x 7in the U-lock fits larger frames and e-bike components more easily than compact locks.

Who It's For

This kit is aimed at urban riders, e-bike owners, scooter users, and anyone who needs to secure a heavier bike or several bikes at once. The combined U-lock and cable let a rider lock both frame and wheels or loop around fixed objects that a U-lock alone cannot reach.

Riders who need minimal weight for long rides or those looking for a quick, ultra-light option should look elsewhere; at 1.54kg the U-lock has noticeable heft. Also, those needing a mounting bracket should plan for a separate bracket purchase because one is not included.

Pros & Cons

Pros

• Robust 18mm shackle and hardened cable offer solid physical deterrence against common attacks.
• Double deadbolt and quality zinc alloy cylinder improve tamper resistance and everyday reliability.
• Three keys and a dust cover make the set practical for regular outdoor use and key management.

Cons

• The lock is relatively heavy, which some customers may find cumbersome for long rides or minimalist setups.
• No mounting bracket is supplied, so carrying options require an extra purchase or bag storage.

Are spare keys provided?
Three brass keys are included so you can keep spares at home and work to avoid losing access.

Is a mounting bracket included?
No. The package does not include a bracket, so plan to carry the lock in a bag or buy a separate bracket.
