Abstract
Abstract A bicycle frame has a two-part horizontal frame member or crossbar, a forwardly extending diagonal frame member pivotally connected to the pedal crank housing and a keylock connecting the two crossbar pieces together so that opening of the lock permits the frame to be opened, placed around a permanently located pole or the like and then re-locked to prevent removal of the bicycle without opening the lock.
