The Therapytrike

 A low cost, flexible modular transport system designed as a single tub structure and multiple transport options. 
 We all know wheelchair use  may require a number of different wheelchairs.  For example, a wheelchair suitable for use in an indoor environment, such as a shopping centre, will is impossible to use effectively in some outdoor environments, such as on rough, muddy, or sandy terrain.  
Yet often these specialized wheelchairs allowing you access what others take for granted can cost between $5,000 and $10,000 and are used infrequently. Our thought was what if a low-cost modular unit was designed to switch from one device to another. Where the user could choose which additional  transport modules they required.
