MADE A MONSTER MINI BIKE OUT OF JUNK PARTS AND RUSTY FRAME. IT WAS TOO EXPENSIVE TO RESTORE IT SO I DID NEXT BEST THINGMADE A FAT CAT TRAIL BIKE.This bike came out to roughly $350. From getting all the parts to welding and painting the frame it took me about a month to make this bike. Bought rolling chassis for $50 and sold rear rack for $50 as well as rear axle for $50 which lowered/offset the cost of the bike. Motor was $100 bucks and 30 series torque converter was $85 on eBay, handle grips $17, paint and primer around $30, rear sprocket $20, seat $25, jackshaft $65 and tires for free from my other parted out 3 wheeler. As far as tubing goes, I got it at Home Depot 1/2 inch pipe (needed just one $12). it might not be the prettiest bike on the block but it sure is a monstrosity that gets heads turning.
