QR Code Link to This Post I built this bike myself entirely from Ebay parts ordered. Bike is a West Coast bike, seven speed from Arizona. 4" Fat tires, chopper style handlebars, leather case hanging from handlebars. Engine is a 49cc, Four Stroke with maybe 20 hours on it and can push the bike 35 mph or so. Clutch is a custom order, to beef up the transmissions performance and works great for speed and grip. Gas tank was a custom order and made out of stainless steel and mounts behind the seat, 1.5 gals, good for 60-80 miles. This bike is fun as hell and turns a lot of heads, comes with real motorcycle helmet. This does not need to be registered in state of MA either to be on the roads, it is a pedal assisted Bicycle and a seven speed shifter is on right side grip of handlebars.
