Abstract
A pedal powered drive mechanism and an aquatic vehicle having such a mechanism are constructed primarily of lightweight inexpensive moulded plastic. The vehicle has a buoyant hull with a central longitudinal axis and saddle seat. Handle bar steering is mounted to the hull and a pedal powered drive mechanism drives a stem mounted propeller. The mechanism is constructed of moulded plastic components for simple assembly and results in an inexpensive lightweight drive compared to conventional metal components. The drive has a housing with two axially spaced apart shaft bearing cradles. The crank shaft is disposed in the cradles, with opposing crank arms and pedal mounts extending perpendicular to the crank shaft axis and outward of the cradles. A drive pulley is mounted on the shaft between the cradles by sliding a pulley central opening along the shaft over at least one pedal mount. Collars disposed on the shaft between the pulley and each cradle retain the assembly in a simple manner.
