Modular Steering and Braking System for Assistive Bicycling Available to Purchase

There are a variety of commercially available cycling systems for users with physical disabilities. These include arm-driven recumbent bicycle and tricycle frames for individuals with limited leg function and tandem system for visually or mobility-impaired individuals. More complex adaptive cycling systems, such as the BerkelBike, have also been developed, which have integrated arm and leg driving mechanisms as well as on-board motor assistance and, in some cases, Functional Electrical Stimulation (FES). These units cost upwards of US$8,000 and are beyond the price range of many individuals and community centers. All current assistive cycling systems also require some degree of fine motor control, either in the torso or the arms, to control steering and braking mechanisms. That would make these systems inaccessible for individuals with severe motor control disabilities, such as Parkinsons or advanced MS.
