Gravity biking is a sport involving riding specially adapted bicycles down steep hills at high speeds. [1] It is popular in the United States, Thailand, Brazil, Italy, Australia and Colombia. [2]
At an official event in 2017, Cedric Touchette (CAN) reached a speed of 126.31 km/h (78.48 mph), which was considered a world record. [3] [4]
Unofficial racing on open roads is risky, and since 2018 is banned in the town of La Ceja in Antioquia, Colombia after a series of deaths and serious injuries. [5] In February 2023, infobae reported that 35 gravity bikers had died in Antioquia [6] and in September 2024, 20 death were reported for the last few months. [7] The bikers often wear little or no protective gear or helmets during descent although they can reach speeds of up to 120km/h. [8]
The "International Gravity Sports Association" used to organize gravity bike competitions from 2002 to 2019, but no longer holds sanctioned Gravity Bike races. [9] [10]
