A commercially available hand-powered cycle was modified to include remote controlled braking and supplemental propulsion. The electric motor and controls from a common twowheeled electric scooter was adapted to drive a standard spoked bicycle wheel using a chain with an intermediate belt-driven reduction. A freewheeling mechanism was incorporated to allow the handcycle to move forward under human power without producing additional drag required to turn the motor drive. A high-powered linear actuator was employed to engage an existing caliper brake via secondary cable. Both systems are activated with a standard digital proportional radio control unit designed to give the caregiver remote control of braking and propulsion assistance.
