As in able-bodied cycling, para-cycling also consists of road events and track events. Athletes are divided into four classifications depending on their impairment type, and ride on bicycles or tricycles that are specially-designed to meet the specific needs of each athlete's impairment. Amputees and athletes with cerebral palsy ride on a bicycle or a tricycle depending on their level of impairment. Visually impaired cyclists ride on a two-person cycle called a tandem, where a sighted 'pilot' rides in the front and leads the way. Athletes who have lower limb impairment ride on a hand-operated cycle called a handcycle (road events only).
