Human powered vehicle |
摘要 |
A human powered vehicle of the pedal-driven type having three or more wheels, a frame and seat for supporting one or more riders in a generally supine position, and a streamlined shell enclosure with a transparent canopy which is openable for entry and egress of the rider. The preferred embodiment for a single rider has two steerable wheels located forward of the rider at approximately the widest part of the streamlined shell, and a single fixed drive wheel centrally positioned behind the rider. The drive wheel is equipped with a multi-sprocket gearing arrangement, and a large pedal-equipped sprocket wheel is mounted in a position slightly forward and above the common axis of the front wheels for ready engagement by the rider's feet. A single drive chain extends from the drive sprocket to the sprocket cluster and passes around idler rollers which direct the chain beneath the rider.
