A drive wheel system 100 comprises a frame connector 160 configured to be rotatably connected to a portion 142 of a frame 140 of a vehicle 150, a wheel connector 162 configured to connect to a wheel 110; and an arm 164 extending between the frame connector and the wheel connector, wherein the arm has a first configuration and a second configuration, wherein in the second configuration the wheel connector is located further forward than in the first configuration. The system may comprise a head tube 142 which may also define a steering axis. A second invention relates to a vehicle comprising a first frame portion (270, see fig. 4) comprising a head tube and a second frame portion (280), wherein the second frame portion is movable relative to the first frame portion. The frame having a first and second configuration, wherein in the second configuration the head tube angle is less than in the first configuration.
