Hi Sho, really- get a bike with two brakes and preferably, at least V brakes. You can find cruisers with those brakes and a derailer to give you some gears. Better, would be a bike with a suspension front end. I also reccomend a sus. seat post.
As for the engine- the best thing is the ex chamber. Look at the shift kits by Sick bike parts- a totally cool add on.
