The lock attached to the seatpost has jaws which fix the back wheel. On top of the lock is a QR code which can be read by a smartphone to unlock the bike. The bike can be left at a Mobike stand which is just a marked-off area of pavement, or it can be left anywhere bikes can be parked (with exceptions like gated areas and underground parking).
