Okay I'm NEW to the whole motorized Bike thing. I just got a complete GT aluminum bike out of the trash (sweet!), and once I looked it over for a second my brain, as it always does, started cutting, chopping, lowering, and basically emphasizing it's better features to harken back to the old board track racers. Now I have the rolling chassis planned out, and I need to know a few things about gas powered bikes; 1) am I legally allowed to make it fully gas powered and just 86 the pedals? (whatever it takes...) 2) what is the gas mileage on a good 3-5 hp engine? 3) What would be the speed and torque range on said 3-5 hp engine? 4) what type of breaking system would be recommended for this set up?, and 5) that is all...for now
