U-Shaped Electric Bicycle Lock

Four digits. One U-shaped lock.

Keep a combination lock in your bicycle setup with this black U-lock and contrasting red controls. The supplier lists alloy-steel construction and a four-digit code mechanism, with a stated weight of 1100 g.

A clear combination layout

Four number wheels sit in the centre of the crossbar, beside a sliding control. The product photos show a U-shaped shackle and a separate mounting bracket. Follow the supplied instructions to set, check and operate your code; the listing does not provide a verified reset sequence.

Measure the space you need

The supplier’s dimension photo marks 11.5 cm across the inside of the shackle, 26 cm overall height and 20 cm across the crossbar. The overall height is not the usable inner height. Compare the required space around your bicycle and intended anchor point before choosing this lock.

Carrying it on the bike

A two-bolt bracket with a release button is shown holding the lock on a seatpost in the product photos. Its clamp diameter and suitable mounting range are not specified. Check your bicycle’s mounting area and clearance before fitting the bracket.

Black finish with red controls

The sole Black option is the black-bodied lock shown with red details on the crossbar and code surround. The supplier’s electric-bicycle wording describes an intended vehicle application; the verified locking method here is the mechanical four-digit combination.

Choose security to suit where you park

No independent security certification or tested attack-resistance rating is supplied. Check any security requirements that apply to your parking location or bicycle cover, and avoid treating the supplier’s security wording as a theft-proof guarantee.
