Could be superfluous given how much time that thing looks like it'd spend in the air in general and waving its front tire in particular.

Me, not being a jumper - I'd love to give it a go.

So how does the front wheel get powered?  is it some kind of worm gear?

  Yep, Amellican made but with a Honda engine sort of.  At least the 450,  The 300 uses a gas gas engine but is not street legal.

 These have been around for several years now . Geoff Aaron rode one in the last man standing circa 2008 , finishing second . My understanding is the concept works really well in low traction situations , maybe not so great on pavement .
