I'm creating a self balancing bike (something like this: https://www.youtube.com/watch?v=kEctw-TUCcs).
I am a little unsure how to drive the rear wheel. I need a system that keeps the bike 'narrow' to aid balance and would like to buy off the shelf components if possible.
The video shows a gear mechanism. I've considered right angled motor with an appropriate wheel. Or perhaps a belt driven rear wheel.
Can anyone recommend a method and some components. Once I have an idea of a good method and the type of parts available, I can then start to size the motor that I need.
