A human-propellable vehicle 1 is described. The vehicle 1 comprises a chassis 2, and a rear wheel assembly 5 mounted to a rear portion of the chassis 2. The rear wheel assembly 5 comprises a double wishbone suspension assembly, each wishbone 14, 22 of the double wishbone suspension assembly being coupled to the chassis 2 at first and second coupling points 10, 16, 20, 30, the second coupling point 16, 30 for each wishbone being closer to the rear of the chassis 2, and closer to the longitudinal axis of the vehicle, than the first coupling point 10, 20 for that wishbone. By using a double wishbone set up at the rear of the bike instead of the more conventional trailing arm type set up it is possible to control weight transfer more efficiently. By providing a second coupling point 16, 30 for each wishbone which is closer to the rear of the chassis 2, and closer to the longitudinal axis of the vehicle, than the first coupling point 10, 20 for that wishbone, it is possible to utilise a double wishbone type suspension setup without having to adopt a higher seating position and without having to increase the rear wheel track beyond anacceptable width.
