$70 1 speed pink Huffy Cranbrook bike, oiled up, works great!

Single speed beach cruiser bike from Huffy. Works great. The Cranbrook's wide tires give you increased stability on the road. Should fit a wide range of heights by adjusting seat. I've oiled the chain and other metal components. Good tires, good inner tubes. Pedal backwards to brake. No gears or hand brakes to mess with, which are always the first things to have problems on bikes.
If you want a good working bike today for a low price, this is the way to go.
