[wheelchairdesign]

Hi! My name's Andrew and I'm a Masters student in the UK. For my final project (thesis) I'm looking at creating a variable gearing system for a manual wheelchair. The idea is to create a system where the wheelchair user could change the input/output ration when they get to a hill, similar to what a bicycle rider or car driver would do. I've set up an online survey, and would be really grateful for any help. Feel free to respond to this post as well with any questions/feedback/suggestions. Thanks a lot for the help!
