I found this JC Higgins exhaust tank bike at a barn sale today. It is a 24 x 2.125 bike. The rust comes off when you run your hand around on it. It needs a front rusty fender stay. The bottom of the tank has a hole where the battery probably leaked. The best thing about it is the wheels spin perfect. It pedals and brakes like it was just serviced...lol Well maybe not That good but it can be used like it is. It needs some 24 x 2.125 tires. Not sure on older tires or new white walls. This will be a great rideable rust bucket!
