Building a wheelchair with off-the-shelf parts is exciting and challenging. Our biggest obstacle is connecting the wheel to the motor in a way that it has a braking system. As a non-mechanical person, I don't totally get the hows and whys of it, but I do get the part about how bicycle wheels don't drive backwards. So, our engineers are working on how to solve this problem as cheaply and easily as possible. | Building a wheelchair with off-the-shelf parts is exciting and challenging.

You can see all kinds of these advertised on YouTube... motors that you pop onto a manual wheelchair and off you go. Oh, boy, do I have problems with these. Gut instinct mostly, but some specifics I can name are: low speed, cost, sturdiness concerns, brake questions, low torgue for getting over bumps... We wavered back and forth for several meetings, but finally decided not to go that route. |
