AM-10 tryke is intended for early intervention. Their fixed drive helps children who might otherwise have problems making a full pedal rotation. Coasting is not possible with a fixed drive; when limb motion stops, the bike does as well. These hand & foot trykes are designed to stimulate reciprocal movement and increase range of motion. Since these are hand & foot trykes, make sure both the rider’s arm and leg length fit within the range. Available in Amtryke red. Assembly required.
