Bike U Lock with 4ft Security Chain 14mm Shackle

$9.99
Catalog updated 2026-10-21

This Weogine bike lock combines a U lock with a 4ft security chain, giving riders two ways to secure a frame and wheels. The 14mm shackle adds substantial heft to the primary lock, while the chain extends reach around racks, posts, and other fixed objects. Three keys come included, along with a mounting bracket for carrying the lock on the bike.

The 4ft chain is the flexible half of the setup, useful when a rack is too wide or too far for the U lock alone. Riders can run the chain through wheels and frame, then close the U lock around a fixed anchor. The 14mm shackle is built for everyday locking rather than lightweight travel, so the combination suits commuters and recreational riders alike.

Weogine lists this lock for road, mountain, and electric bikes, which covers a broad range of frame shapes and tire sizes. The included mounting bracket keeps the U lock off the frame during rides, and the three keys provide spares for household use. It is a practical two-piece locking kit for riders who want chain flexibility alongside a rigid U lock.
