Petrol driven bike!

Heard a right racket coming up the street the other day. Expecting to see a youth in bandana on a quadbike I was bemused when the "thing" shot past me to see it was a pedal cycle with a petrol engine attached. I was too surprised and the rider was too fast to actually see where the engine was mounted but I did see that he wasn't pedalling so it must have been throttle controlled. And secondly it wasn't one of those 1940s French things but was a mountain bike. I assume it must have had the engine retrofitted therefore. Does anyone know more about rhese, is it legal, is it a kit or has someone shoehorned a lawnmower engine onto a bike? I can see no reason whatsoever for such an abomination save the love of noise and the smell.

Although my 56 yo self would agree with Gavin and Nosweat, I grew up with Castrol R flowing through my veins and a lust for Micron and Allspeed exhaust pipes with cut down baffles, so I must confess if I could have had one of these systems for 2 weeks paper round money.......

I agree with you totally Pete- I spent 15 years racing 2-strokes. The sound/ smell of a Kwakka H2 or GT750 on Microns or Allspeeds is pure Nirvana...

The RC jet powered bikes are awesome, they are insane but you have to love them.

Almost all are illegal, but people have been known to jump through the hoops and register them.


At a car show some years back I saw a Raleigh Chopper that had been thus adapted, and that was all registered and plated.
Indeed, 70 years ago they were commonplace with over a million registered in the UK. But with the passing decades and changes in the regulations it gets ever more difficult. I believe emission regulations will eventually kill them off.

Spookily enough in the last 2 weeks when I have been out on my bike I have seen these things buzzing about in the Rochdale area. Sounded like a strimmer engine or similar. I did not see how they went as they were just crossing both times at a pedestrian crossing while I was stopped at the lights.
I cannot imagine any coppers ignoring these things as they do make a racket, but I guess the users are not the sort to hang around and discuss it, they would be off down a back alley.
