Goes about 40mph. About the same with gas too! No back tire There’s a plate piece that goes on the back tire for one of the two chains The other is for the gear. After that. To ride it, you’ll need to hold the clutch lever on the left side of the handle, below the brake lever over it. There is a brake lever on both sides You hold the clutch on the left side and peddle until it catches a start then you let go of the clutch and ride. To stop, you slow down and hold the clutch until it shuts off or you can press the yellow off button. Takes some time to practice but beyond that everything works perfect! Comes with lights, lock, and new wide seat
