ABSTRACT:
A pontoon water bike raft comprises two rear pontoons disposed parallel one another on either side of a longitudinal axis, with a transverse, planar truss spanning between them. Coupled by quick release joints to the midpoint of the truss and extending forward to rest on a third, front pontoon, a vertical frame supports a swivel seat for a driver. The frame includes a steering column similar to that of a conventional bicycle, allowing steering the water bike by turning the front pontoon. The steering column is tilted rearward slightly, and rests on the front pontoon rearward of its longitudinal center, to provide positive steering return when released. To propel the water bike, the driver manipulates a foot pedal mounted near the steering column and coupled by a chain to a transverse axle beneath the seat. Coupled to the axle are a plurality of planar water paddles arranged around a hub. The water bike quickly can be disassembled by uncoupling the frame and truss from the pontoons and from each other, and removing the seat from the frame and the paddle wheels from the axle.
