Re: Hello From Gainesville, FL
the thing is boxer is only 48cc which makes it technically street legal in most places ).
imo, good luck getting a 150 cc motor into a bike that you would want to take over more then a pot hole. you're gonna want a full suspension bike for off roading imo, and most full suspensions are incredibly hard to motorize. with a morini costing $500 and needing tons of custom fabrication i think $2,000 for it is actually a pretty good deal.
but if you think you can get a 150cc into a bicycle and provide a safe and fun ride all the power to ya, looking forward to seeing what ya come up with.
