OnGuard Bulldog Mini U-Lock with Cable

The compact 5.52" x 3.55" size is intentional. A smaller shackle leaves less room for thieves to insert leverage tools like jacks or pry bars, making it significantly harder to break than larger, more spacious locks.

The cable is designed to secure your front wheel or accessories like your helmet to the main U-lock. It isn't meant to be your primary security, but it provides essential secondary protection for parts that are easily removed.

No, the lock features built-in anti-rattle bumpers that keep the shackle secure against the crossbar. This prevents the annoying clanking noise often associated with carrying metal locks on your bike frame.

The EZ Mount bracket clamps onto your bike frame, allowing you to carry the lock conveniently while you ride. It is designed to be adjustable so you can find the best position that doesn't interfere with your pedaling.

OnGuard provides a key code with your purchase, which you should register immediately. If you lose your keys, you can use that code to order replacements directly from the manufacturer.

This lock offers robust protection with its 13mm hardened steel shackle and double-bolt mechanism, making it a strong choice for daily use. However, for high-risk areas or long-term parking, you might consider pairing it with a heavy-duty chain lock for maximum security.
