A bicycle U-lock offers a rigid locking shape for everyday bicycle parking. This ROCKBROS design uses heat-treated steel with a silicone covering to reduce direct contact against the bicycle, together with a key-operated cylinder and a dust cover.
The lock measures approximately 21 × 11 cm, or 8.27 × 4.33 inches, and a mounting bracket provides a way to carry it on the bicycle. Two actual configurations are retained: U Lock and U Lock and Cable. The cable bundle adds a 1.2 m double-loop steel cable; that cable is not included with the lock-only selection. Choose the configuration that suits the bicycle and the fixed object you intend to use. Check that the locking space is suitable, close the lock securely, and keep the keys accessible. No lock design is treated as a guarantee against every theft method.
