An adjustable pedal arm is mounted on an occupant powered vehicle. The pedal arm is elongated and tubular, extending from one end, mounting pedals and cranks, to a remaining end that is pivotably mounted to the vehicle frame for adjustable pivotal movement about an axis. An internal drive assembly is provided within the pedal arm, extending from the crank arms to the remaining end of the pedal arm. An external drive assembly connects the internal drive assembly to at least one of the vehicle wheels. An adjuster is mounted between the pedal arm and vehicle frame to permit selective adjustment of the pedal position relative to the occupant seat. The pedal arm with the use of a pedal arm adjuster, pivots about a jack shaft located on the vehicle frame to meet the occupant's preferred pedal position.

A relay control system is disclosed for alternately energizing and deenergizing a non-latching relay in response to successive applications of an AC impulse control signal to a control signal input. An impulse processing circuit converts the AC impulse control signal into a DC pulse. The DC pulse toggles a first flip-flop. The output from the first flip-flop is gated through a second flip-flop in response to a clock signal produced by an AC zero-crossing detector to synchronize the second flip-flop output with zero-crossings of the AC power signal. The output from the second flip-flop operates driving circuitry which energizes and deenergizes the relay coil, thereby toggling the relay. A power up reset circuit deenergizes the relay in response to the initiation of the AC power signal and presets the logic circuitry so that the next impulse of the AC control signal will energize the relay.
