Each year, the James Dyson Foundation runs a competition for the most innovative new designs. This year, Seth Astle took home the award with his design for Cadence, a prosthetic limb and bike pedal that makes bicycling easier for amputees. Prosthetic limbs can be specialized for different activities. You've likely seen the Cheetah, a design specifically for runners. Seth took the idea of limbs made for specific sports and applied it to cycling.

"Currently, cyclists with other prosthetics have a limited range of motion and cannot pivot their feet. Astle recognized the limitations of other prosthetics and worked to provide a solution," notes the press release.

"The prosthetic has an elastomeric band that collects energy while riding, giving the cyclist added muscle strength. As the foot rotates, kinetic energy snaps the foot and leg back up and around to the top. By combining the pedal and prosthetic, the cyclists can clip into the pedal, allowing more control and ease of use."

Among the 500+ entries from 18 countries in this year's competition, Seth's design stood out. The student from Art Center of Design in Pasadena, CA, won a $1,400 award and will be one of the finalists for the international award announced in November. Not only that, but a prototype will be on display at the 2012 Olympics in London.

We love that this design makes bicycling more accessible and comfortable to people. Not only is it great for those who want to cycle competitively, but could also be useful for bike commuters.
