Although, it is interesting that the bumpers are not completely fool proof.
You are right about not being able to ride off the front or back. The rear wheel is 'captured' by mini rollers that make this impossible. On the DIY versions of the e-motions, I have not seen anyone replicate the mini-rollers, just the in-line skate wheels that keep you from riding off the side.
