?:definition
  • Third-wheel devices that are controlled and/or pedaled by the hands designed for attachment to a wheelchair. These devices usually consist of a front wheel with a crank mechanism including hand pedals and handbrakes, kick stands for keeping the third wheel upright in a parking position, and an adapter for connecting to a wheelchair. They make a three-wheel cycle by their attachment to the front of a wheelchair. These devices can either be manually operated, or battery-powered. Wheelchair handcycles are mainly used for facilitating locomotion by people who are usually restricted to a wheelchair. They can also be used for recreational purposes.
