Bike is a kind of transportation that comfortable to ride. We can ride it when we adult because it is tall and complicated to ride. This bike is so unique because it is so different from usual bikes. This bike has thin wheels, but usual bikes have wide wheels. The brakes of this bike are different from usual bikes. Usually, we control the brakes with our hands, right? Different with this bike, we control it with our legs by turning the pedal to the other direction. We can ask our friends or parents how to ride this bike. I never ride this bike, but I guess it's a really good bike. I really want to buy this bike, but my parents are not allowed me. Do you know what kind of bike is this? It's Fixie bike.. J
