ROCKBROS 4-Digit Folding Lock | eBikes, eScooters and eMotorcycles

The ROCKBROS Folding Bike Lock combines keyless convenience with a compact design for everyday theft deterrence. Its 4-digit resettable combination provides up to 10,000 possible codes, so there is no separate key to carry, lose, or replace.

Thickened alloy steel bars create a strong folding barrier against common cutting and tampering attempts. A zinc alloy lock cylinder supports dependable operation, while the 360-degree rotating head makes it easier to position the combination mechanism from different locking angles.

Extended Reach with Compact Storage

The lock opens to 33.5 inches, providing useful reach around compatible frames, wheels, bike racks, and other fixed locking points. After use, the linked bars fold into a compact 7.6 x 3.5 x 1.4-inch package that is easier to transport than a full-length chain.

A smooth ABS coating helps protect the bike’s finish from scratches during locking and transport. The included mounting bracket can attach to a compatible frame using screws or adjustable straps, keeping the folded lock organized and ready for the next stop.

Why It Stands Out

The keyless combination system removes the hassle of carrying a key, while the rotating head makes the controls easier to access. Thickened alloy steel bars, a zinc alloy cylinder, protective ABS coating, and two bracket installation methods create a balanced setup for commuters and recreational riders who value portability.

Change the default combination before using the lock. No bike lock can prevent every theft attempt, so secure the frame to a solid fixed object, minimize open space inside the lock, and park in a visible area whenever possible.

Best For

• Daily commuters who prefer keyless bike security
• Folding bike and scooter riders who need compact lock storage
• Recreational cyclists looking for extended reach without carrying a chain
