Check with state laws. For example, motorized bicycles are allowed in California provided that they do not exceed a specific and that they can still be operated using the pedals.

Nice engineering going on there

I notice your selling a moped in the backgroung... How much?

what the hell is the point its nt a real motorbike nt a real cycle youll need a licence on the road and not powerfull enuff to go off road wot a load of rubbish

hi there,
is the tunned pipe already available ?
did you think of improving the cylinder and sale high performance ones ? There's a lot that can be done on the cylinder, like changing the areas of the transfer ports, and changing the timing of the blow out, etc etc. Also would be great if you could do a piston with more material on the crown to raise compression to about a decent 9:1, I think stock is like 6.5:1

with that exaust is it still street legal

HI,
If a motorized bike is legal in your area to start with , the addition of the pipe alone will not make it illegal in itself unless you have certain speed restrictions in place that the pipe may allow you to exceed. Also, if your bike comes equipped with a Catalytic converter (believe it or not some actually do), the removal of the stock setup and use of this pipe may conflict with EPA regulations (much like doing mods to a car)....The sound level of the pipe is about stock. Thanks! Andrew

do you use the jack shaft method for changing gears? do you think i could buy multiple sprockets and have a backwards derailleur to change gears?

I like your sprockets! I've been waiting three days for a machine shop to enlarge the center hole to the 2.052" necessary to clear my disc break hub and if it's not ready, you will be getting a call from me quite soon. When will the tuned pipe be available? Also, I live in SF, CA where I need the motor to by big butt over some rather big hills (Twin Peaks). I'm running a 44T on a 24x2.1 tire/rim. Will a bigger gear help?
