Don't know how many other people saw it, but the concept was kind of neat. The bike seperated from the front 2 wheels and had one back wheel they could ride. In the movie/series, the guy using it was a disabled vet with no legs and one arm. The steering was done by a centralized column not by bars. The peripheral is on the zon.

I am not saying this is viable, but it was a neat idea.

did a short googly search but couldn't find a clip to attach/link
