The handcycle is an engineer who works on the body using his or her arms rather than legs. It is normally in the recumbent or kneeling position, and the hand cranks are interconnected with the chain.
Handcycles provide individuals with leg disabilities the opportunity to participate in road racing, time trials, and triathlons. There are fast and aerodynamic two-wheeled handcycles as well as stable three-wheeled ones that handle well on rough terrain and hills. Handcyclists develop strong upper bodies, hearts, and bike-handling skills. Handcycles are included in many competitions with various categories to accommodate all so everyone can participate and be included in the endurance category.
