I like how the headline is "Jet bike is not safe." Well no shit.... :lol:

That thing scares me...

That engine is going to burn through that tiny tank of fuel is less than a minute..

with all that propulsion on one side... I seriously doubt you'd be able to ride straight... or even at all...

Yeah, you need a second one on the opposite side.

but even then remember the scooter that was rocket powered? it fuck'n looped in like 2 seconds... let me see if I can find the you tube video

Yeah the problem with the scooter was that the thrust was vectored slightly downward. As long as the thrust isn't giving lift then it should work.

now i want to see a video of the rocket bike in action..
