Hey everyone, i recently got an assignment for my engineering class where I have to design an easy to balance bicycle for a local children's rehabilitation center. It can't use training wheels, what they're looking for is something that can progressively transition from self balancing to harder and harder to balance, until a normal bike can be used. Anyone have any ideas on a clever way to do this? Some things i've thought of are:
1. switching out the front wheel with a row of interconnected skateboard/rollerblade wheels (similar to flowboard trucks) that are arranged in a curved U shape, making it easy to balance than a normal wheel, but with a slight challenge
2. having a thick wheel on the front that can either be pulled apart or pushed in to change the thickness, or have it divided into sections that can be taken out.
3. throw on a small cylindrical wheel to the front, which would make it easy to balance but not really challenge the rider
any ideas would be great, thanks
