Storage and portability: It can fold down to half of its size making it perfect for storing in your house or car trunks. One size fits all: It's highly adjustable to fit every users' individual needs. Its cockpit reach, handlebar height, and seat position are all designed with adjustable systems to accommodate all types of body conditions. Suspension: Elastomer suspension is designed onto the frame to bring comfort, stability, and a big smile to HANDY users! Power assist(optional): Human's hand power output is only 1/6 of leg power output, therefore instead of using a regular bicycle motor we developed new motor systems specially for handcycling. This handcycle motor system provides assisting power while cycling with both hands simultaneously.
