Ampt Biking Expands Adaptive Riding Events in 2021 with 3 US Events Last year we had the opportunity to check out Ampt Biking’s first-ever Pedals and Prosthetics event in Estes Park, Colorado. Mathew Beall, a congenital amputee created the organization for other amputees and adaptive athletes to have a gateway and community experience if they want to try mountain biking. Working with a few different partners, Ampt had several attendees at the Estes Park event last August, and this year they are holding additional events in Rogue River, Oregon and Moab. The dates for the 2021 events are as follows: Rogue River, Oregon at Mountain of the Rogue on Sunday June 13
