Abstract: A recumbent bicycle for use by disabled users. The bicycle includes a seat unit that is adjustable in both the horizontal direction and in the vertical direction as well as a pedal unit that has a motor for controlling both the time and rotational speed of pedals. Straps are located to hold the user in the seat unit. The pedals are oversized with respect to the user's feet and have a heel-engaging ledge as well as straps to hold the user's feet on the pedals.
