A human powered vehicle of the pedal-driven type having four wheels, a composite monocoque chassis, four wheel independent suspension, and seat for supporting one or more occupant/driver/riders in a generally supine position, and an aerodynamic chassis 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, and two fixed drive wheels 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 the rider's feet. A single drive chain extends from the drive sprocket to the sprocket cluster and passes under/over idler rollers which direct the chain beneath the rider. Accordingly, the vehicle's chassis, suspension, and propulsion systems can be utilized on an enclosed track for exercise, recreation, and to simulate the sport of car racing.
