A two-wheeled vehicle comprising a frame, a pair of wheels, and a pedal assembly. The pedal assembly has a sprocket, right crank arm assembly and a left crank arm assembly (the crank arm assemblies include pedals), wherein at least one of the two crank arm assemblies comprises an outer member and an inner member, typically, the inner member being cylindrical at least partially telescopically received in the outer member. Typically one of the inner or outer member is moveable, telescopically between a retracted locked, fixed position and an extended locked, fixed position. In the extended position, the two members lock with respect to each other and allow the bicycle or other two-wheeled vehicle to lay adjacent the support surface on the removed end of the extended member, which extended member typically contains the pedal portion of the pedal assembly.
