Large Bike Locks Heavy Duty Anti Theft

$29.99

Catalog updated 2026-10-21

This wheel lock centers on an 18mm thick shackle, a substantial cross-section intended to resist cutting and prying. The bulk suits machines that carry real value and sit unattended in public, where a slim cable or thin U-bar would offer little deterrence. Riders of e-bikes, e-scooters, fat-tire bikes and dirt bikes are the intended audience.

Three keys ship with the lock, so a spare can stay at home, in a bag, or with a riding partner. The keyed cylinder keeps operation simple, with no dials to spin or codes to remember in bad weather. The lock body is sized to pass through wheels, frames and fixed anchors where clearance allows.

Because the shackle is thick, the lock is heavier and bulkier than compact alternatives, which matters when packing for a commute. It is best treated as a stationary security piece rather than something carried in a jersey pocket. Pairing it with a second lock can secure both wheels on higher-risk machines.
