How about some pedal power as a competitive sport, or a leisurely ride with family or friends? There are all kinds of different bikes and trikes and adaptive equipment. Adapted bikes come in all shapes and sizes, from bicycles-built-for-two for blind and visually impaired riders to handcycles for those with mobility impairments. Trikes are great for those with balance issues. If competitive cycling is more your speed, there are competitions in road events, pursuit, sprint and individual time trials.
