Chassis 10 comprises front and rear sections 12, 14, each carrying two road wheels. The sections are connected so that they can pivot with respect to each other about a longitudinal axis. Suitably, elastomeric members connect the two chassis sections. The vehicle has a handle which may be connected to its steering mechanism, by which the vehicle can be led by a user on foot. Drum brakes are used, whose shoes and other components can float relative to a fixed backplate, so as to ensure that the shoes act equally on the drum. The chain drive has a clutch, preferably a dog clutch, to allow gears to be changed down while the vehicle is stationary. Numerals 34 represent leg guards for the rider. The vehicle is intended for carriage of goods, with interchangeable bodies which may be fitted to the chassis. |
