[1] In 2008, BBC Sport defined this classification as "HCC: For athletes with complete loss of lower limb function but few other functional disabilities, or for athletes with partial loss of lower limb function combined with other disabilities which mean conventional cycling is not viable"[1] In 2008, the Australian Broadcasting Corporation defined this classification as "Handcycling (HC): Cyclists in handcycling race on bikes with two big wheels at either end — they sit in the middle and use a hand pump rather than pedals to propel themselves forward.
These competitors usually require a wheelchair for mobility or are unable to use normal bikes or tricycles because of severe lower limb disability.
"[2] The Australian Paralympic Education Program defined this classification in 2012 as: "For athletes with complete loss of lower limb function but few other functional disabilities, or for athletes with partial loss of lower limb function combined with other disabilities which mean conventional cycling is not viable"[3] Cycling first became a Paralympic sport at the 1988 Summer Paralympics.
This policy was put into place in 2014, with the goal of avoiding last minute changes in classes that would negatively impact athlete training preparations.
All competitors needed to be internationally classified with their classification status confirmed prior to the Games, with exceptions to this policy being dealt with on a case-by-case basis.
