g'day guys im new here, my names chris and im from sydney australia, im currently begining work on motorizing a one off custom lowride push bike, im torn as to whicch direction to go, petrol or electric, im leaning towards an 80cc petrol as they are cheaper, have better power and better range, but mounting and petrol engine in my lowrider is going to be no easy task. see pic below. the chain is gonna get massivly in the way. i fear my only option will be a hub mounted electric engine. however i must comute 25 miles a day, and i way about 220 lbs, i dont think the electric engine can keep up my target speed of aboute 30-35 mph... any help would be muchly appreciated.
