It started with a $15 Craigslist purchase. The seat is the backrest from a golf cart. The whole thing was completely rewired using wire from a washing machine. The LED headlight and taillight are from eBay, while the back tires and hubs are from a Honda ATC 125. The rear brake is from a moped. Used a couple 5AH SLA's for the starting battery. Total cost was $38.50. Can't beat that!
