Thank you for viewing. I have used it a few times and stored it at home. The younger sibling of Q-BIRO, made even more compact. This compact lock uses a uniquely developed "shape-memory cable (bi-rotation)". Unlike regular coil cables, which can stretch out of shape if pulled too hard, Q-BIRO's shape-memory cable is designed to resist stretching. Q-BIRO MINI, with a concept opposite to Q-BIRO, which can lock both front and rear wheels of a bicycle, prioritizes portability with its compact design! It's recommended for road racers who want to travel light, or as a secondary lock. Locking the object and the top tube can also help prevent the bicycle from falling over while parked.
