U-lock ONGUARD 8152YL — ONGUARD U-lock 115 mm x 292 mm with bracket and 2 keys (yellow)

ONGUARD 8152YL U-lock is a compact and rigid bicycle security device with internal dimensions of 115 mm x 292 mm, supplied with a handlebar mounting bracket and two keys. The lock combines a hardened steel U-bar design with a portable form factor suitable for everyday urban cycling and short-term locking of frames and wheels to fixed objects. The yellow finish increases visibility and simplifies identification among other accessories.

Advantages

The U-lock provides strong resistance to twisting and cutting thanks to its hardened steel U-bar and reinforced locking mechanism. Its compact size keeps weight and bulk low while offering practical internal clearance for securing frame tubes and one wheel to a post or rack. The included handlebar bracket allows convenient transport without additional bags, and two supplied keys reduce the chance of lockouts. The yellow color improves visibility and helps locate the lock quickly.

Suitable for

• Everyday urban cycling and commuting
• Securing children’s and small-frame bikes
• Short-term locking at bike racks, posts or railings
• Use with rear or front wheel plus frame when geometry allows

How to use

Position the U-lock so the shackle surrounds a fixed object and the bicycle frame or wheel leg, ensuring both are secured within the internal clearance of 115 mm x 292 mm. Insert the shackle into the locking body and turn the key to lock; verify the mechanism engages fully before leaving the bicycle. Mount the bracket to the handlebar or frame using the supplied fittings when transporting the lock; slide the lock into the bracket until it clicks to prevent rattling. Keep the two keys in separate safe places to avoid being locked out.

Usage recommendations

For improved security, use the U-lock in combination with a flexible cable or chain to secure both wheels and the frame where space permits. Choose well-lit, visible parking spots and orient the lock so the keyhole faces downward to reduce exposure to weather and tampering. Regularly clean and lubricate the locking mechanism to maintain reliable operation.
