Bike Locks Heavy Duty Anti Theft

$24.99

Catalog updated 2026-10-21

This U-lock is built around a thick 18mm shackle, giving it a sturdy profile that suits higher-risk parking situations. The hardened steel construction is intended to resist cutting and prying, making it a practical choice for riders who leave their bikes in public areas for extended periods. Its weight and solid feel reflect the heavy duty design rather than a lightweight commuter accessory.

Three keys are included with the lock, providing spares for everyday convenience. The keyed mechanism avoids combination dials, which can be preferable for riders who want a straightforward locking routine. Because the lock uses a U-shaped shackle, it can be threaded through a frame and around a fixed object such as a rack, post, or railing where the fit allows.

The design is aimed at electric scooters, motorcycles, mopeds, dirt bikes, and tri-bikes as well as standard bicycles. That broad compatibility comes from the shackle size and the space inside the U, which accommodates thicker frame tubes and wheel assemblies. Riders looking for a single lock to cover several types of two-wheeled vehicles may find this format useful.
