OnGuard Locks Standard U-Lock

Fashioned from hardened steel, it helps to ensure that your bike will be safe and in the exact spot you left it.

Featuring OnGuard's "X2 Power" double-bolt locking mechanism, this bicycle U-lock can fix its shackle in place on both sides.

That allows for a solid interface between the U-rod and the cross bar.

It features a patent-pending Z-cylinder, which is a unique mechanism that provides more security than traditional locks.

When combined with the pick, pull and drill-resistant cylinder, it provides virtually unbreakable protection for your bike.
