Pushie goes 236kmph

Translation required!

Scenario: Gentleman with far too much time on his hands designs a small jet engine. Oh wait, it's too small for a plane. What will he do with it? That's it, attach it to a MTB frame! Quite logical really. But wait, the bike still has what looks like a conventional drivetrain. Hope he hasn't completely taken leave of his senses and gone fixed. Now that will stuff his knees.
