do they make engines for kick scooters?

[zamanakhan]

i remeber when i was a kid and the kick scooter fad was starting i got my mom to buy me one but i have probably used it 3x total and i think its just lying around somewhere. Do they make engines for those? i was thinkin of puttin a motor on it but i dont know how i would rig up a ht to do so. i think it would be kinda cool cause u can fold it up and throw in the back of the car if u wanna take it somewhere.
