I left the bike outside of the chemistry building (uni of manchester) using a 5 digit heavy duty combination lock which was attached around the front wheel of the bike. When I got there, the lock was on the floor and the digits were out of line (the lock had been jammed). I think they used the bike seat from another bike to do this as the bike seat was left on the floor next to the lock.
