Drawn from 1970s Californian 'misfit' culture, BMX will be contested over freestyle - making its debut at Tokyo - and racing disciplines.
Aussie Brandon Loupos is the reigning men’s world freestyle titleholder, but can expect a strong challenge from hometown favourite Rim Nakamura, the overall World Cup champion.
American teenager Hannah Roberts has won two of the last three world titles and was the first woman to land a 360 tailwhip in competition.
BMX racing has been an Olympic mainstay since Beijing 2008, with Colombian Mariana Pajon (aka Queen of BMX) claiming the last two women’s titles.
New Zealand has enjoyed previous success, with Sarah Walker winning silver at London 2012, before missing Rio 2016 with a broken arm. At 32, she was again in contention for the NZ women’s spot at Tokyo, but missed out to Rebecca Petch.
