Cycling at the Summer Paralympics

Cycling has been contested at every Summer Paralympic Games since the 1984 Summer Paralympics. From an original program of seven road races, the sport is now contested on both road and track, and since 2012 the cycling program at the Paralympics is typically the third largest of any sport in the Games, behind athletics and swimming, and running at approximately 50 separate events.

Classification
Cyclists are given a classification depending on the type and extent of their disability. The classification system allows cyclists to compete against others with a similar level of function.

At the 2008 Summer Paralympics and earlier, classes were:
 * B&VI 1–3: Cyclists with a visual impairment, using a tandem bicycle
 * LC 1–4: Cyclists with a locomotor disability, including those with amputations
 * CP 1–4: Cyclists with cerebral palsy, using a tricycle (CP 1–2) or bicycle (CP 3–4)
 * HC A, B, and C: Cyclists using a handcycle

At the 2012 Summer Paralympics, a functional para-cycling classification system was used.
 * B: Cyclists with a vision impairment, using a tandem bicycle
 * T 1–2: Cyclists with cerebral palsy, MS or similar neuro-motor impairment, using a tricycle
 * C 1–5: Cyclists with amputations, neuromotor or musculoskeletal impairment, using a bicycle
 * H 1–4: Cyclists using a handcycle

Factoring
In some cycling events, cyclists with different classifications compete against each other for one set of medals. Many (but not all) such events are factored, reducing the times of riders in lower classifications to take their greater impairment into account. Factoring percentages are based on average race times by riders in each classification.

At the 2012 Summer Paralympics, factored races included the mixed tricycle time trial, Women's C1–3 road time trial, Women's H1–2 road time trial and track C1–3 and C4–5 events.
