I was just thinking, 'What if you hit a pothole on that?'
And how does the inner channel of the rim (the bit the motor touches) stay clear of water/dirt? I hate to be negative on new ideas and obviously earnest inventors, but this is a solution in search of a non-existent problem. We already have motorised bicycles for people who want them.
