Tricycle for Quad Amputee

Name: Mandy

Event: TOM: Melbourne Makeathon 2016



Mandy is a quadruple amputee and a motivational speaker. She has two prosthetic hands and two prosthetic legs. She can’t bend her knees past 90 degrees and therefore cannot ride a bike. She also can’t use a recumbent bike.

Mandy’s challenge is to create a device to allow her to ride a tricycle.


Mandy’s team combined and adapted two existing bike frames to make her a new bicycle. Adaptations included a mechanism to allow for back pedal brakes and gears, an electric motor, and new pedal and handlebar placement to allow her better control and reach with prosthetics. Of course, the bike was also painted bright red just as Mandy requested.
