dude i absolutely love this thing, i understand it may be a cheap chinese motor but with the right care these motors can last a long time, as of right now theres no problems whatsoever, has been real happy riding from here on out, i gotta say ive never had so much fun than being on my motorbike! i always put safety first and use my hand signals as a normal cyclist would do, and im hooking people up here in my local town with these kits, its sad to see bmp go, but there are alternative websites im directing them too
