the bike i have is a cranbrook. i suggest before motorizing u dissassemble the wheel bearings and grease them well. i got mine from wally world and they do not take much care when assembling or lubing the bikes.the only prob i had was getting the chains to sync together because it has no derailler to keep the bike chain tensed. mounting u will need to buy a bracket from sick bike parts or make your own for the front mount. i also still am only using the coaster brake which has worked fine for me so far and i have the so called 80cc/66cc. also 1 more thing is get rid of the fenders and get some plastic ones from planet bike..both my fenders broke causing me to almost crash within the 1st 2 days of riding motorized. it was not nice skidding on the back fender at 35 mph, luckily the front 1 i was only goin about 5 mph.
