BORP Adaptive Cycling Program The BORP Adaptive Cycling Center at Aquatic Park in Berkeley hosts one of the largest collections of adaptive bikes in the world, including handcycles, recumbent bikes, side-by-side tandems, and other models. We serve children, youth and adults with physical disabilities and visual impairments, as well as their family and friends. Visiting the Cycling Center Newcomers to the Cycling Center should email us at cycling@borp.org or call at 510-848-2930 before their first ride so we can make sure we are ready to accommodate. Please also include your phone number in your email message! Our friendly staff and volunteers will help find the right bike and fit that works for you.
