The lock measures 205 x 112 mm, which is a medium size suitable for most bike frames and standard racks, giving enough space for convenient locking without being bulky.

Weighing about 5.8 pounds (3.15 kg), it is on the heavier side compared to some lightweight locks, which means it may feel a bit cumbersome to carry around but contributes to its strong build.

This U-lock is ideal for riders looking for a robust, reliable lock primarily for stationary or semi-regular use rather than those prioritizing lightweight or quick portability.
