In recent years, a handsome bicycle has become popular among young people all over the world. Fixed Gear and Track Bike are the same type of bicycles. However, the riding area is not restricted to the gymnasium. In Japan, there is classical gambling. The form of field cycling competition, known as the "race wheel", is called "dead fly" or "fixed-tooth" in China. It is also known as the "terrier" in Hong Kong, and the Fixed Gear Bike is from the bicycle culture of the New York Old School. The rapid cycling culture originally developed by Messenger express workers became popular in Harajuku, Japan, and quickly spread throughout the world, becoming a representative of street culture.

It is a bicycle with no gliding ability and no flywheel. The gear is directly fixed on the axle with screws. Regardless of whether the rear wheel rotates in that direction, the pedal also turns in one direction with it. By fixing the rotation of the pedal, the rider can slow down the bicycle. There is no need for extra brake assistance, and if you go backwards and fly and the bike will move backwards, and the dead fly bike has no upper limit speed, it will also be very crazy.

Stopping in the field of dead fly "drift", drift is the opposite skill of the ankle movement is difficult to stop the rotation of the rear wheel. Putting all the weight on the front wheel can make the drift longer, and this action can leave a deep impression on others. If you want to stop quickly and need a rider to make a jump stop, it's like parking on a crowded road.

Dead-flying bicycles are very beautiful, because they are simplified to have only one frame, two wheels, a handlebar and a carrier, usually without a brake line, no gear converter, no fenders, no lights, no reflectors, No brakes, pure bike.

The "GB3565-2005 Bicycle Safety Requirements" in China is China's current national bicycle safety technical standard. From the point of view of "requirements", the fixed flywheel is not considered to be a brake in China, even if a front brake is added to a dead-speed vehicle, it does not satisfy the "requirements". In the "two brake systems," the provisions, so regardless of whether there is no front brake, die speed vehicles do not meet the "requirements." The "dead-flying" bicycle has only one frame, two wheels, a handlebar and saddle, no brake lines, no gear converters, and no fenders. Play "die fly", mainly by the foot to control the car's forward and backward, but also can make a lot of tricks, good riders can make a fixed pole, drift, winding ride, jumping and other tricks. The young "dead fly" racers often use car friends to engage in partying and leisure cycling. They compare themselves to driving skills or riding on the polo, and experience different riding stimuli. This 'dead fly' is really not fun. There is no technology or no way. Remind everyone again that entertainment should be moderate and safety always be the first.
