This bike can reach over 500 mph, and is one of the fastest bikes around. The bike, called the 'Speedster', was first released in 2054. One of the greatest things about the Speedster is that its fuel is not from fossil fuels, and in fact uses just plants and air! The air comes in through the engine piece on the top of car, and pushes it out the back. To start the car, you turn on the engine (which is powered by plants) and it starts to suck air in.
