Abstract: A multi-wheeled vehicle powered via a twin treadle-acting drive train. An upright front steering assembly including a pair of tie rod coupled front wheels and steering bar-mounted gear shift and hand brake assemblies facilitate operator control of a chain-driven rear wheel. The drive train incudes left and right treadles which, via an interconnected chain and crossover sprockets, drive a rear wheel housing supported stub shaft having a pair of end-mounted, over-running sprocketed clutches, a drive sprocket and a non-reversing clutch. A derailleur-controlled drive chain transfers power from the drive sprocket to the rear wheel.
