$50 · 21 speed Mountain Bike

If you want a low-cost, simple but functional bike, this is it. Its a 21-speed Lamborghini model. It has a new tube in the rear tire; the seat is in excellent condition; and the tires (a type of cross between a dirt and road grip) are good. The bike works okay but could use a few adjustments like oiling the chain etc. I am about 181 cm (6') and I need to raise the seat as high as it will go so this bike is probably suitable for someone 150 cm - 182 cm ( 5 - 6 foot) in height.
