The "standard" two-stroke kits are designed for a "V" frame bicycle, like a normal mountain bike, so you have to drill a hole in some of the crusier type frames in order to mount the motor. I would recomend clicking on some of the links around the forum and finding a kit that fits your price range.(the motors are all the same design-wise, its just qaulty and a couple features that is lacking on the cheaper ones, i personally have a cheap $120 kit that i love)
Thanks, JTG. When you say "V", do you mean V-shaped frame tubing as opposed to round? I'm not certain I want to drill too many holes in the bike.
Also, the most important feature in an engine, as long as it fits, is lack of serious vibration. I want the smoothest one I can find if there is a difference. Customer support and spare parts being readily available are also big plus. I plan to pass this bike down to the kids.
