A hand-powered vehicle with a device for positioning the crank arms so that the rider can easily adjust them for both vertical and horizontal movement and placement. A device for supporting the rider's legs and feet that combines both a leg support and footrest that can be adjusted forward and rearward relative to the front wheel to accommodate different rider leg lengths. A device for triangulating the frame behind the seat in order to increase frame rigidity between the crank arms and the seat back. A self tightening seat with fabric attached in such a manner that the rider's weight holds the seat frame attached to the frame of the cycle. A device for quickly removing and replacing the rear axle while maintaining proper toe in and toe out of the rear wheels.
