The brakes are an essential part of the bicycle, and the brakes are not to stop, but to reduce the speed. In daily riding, the brakes are also skilled, how to control the bike freely when braking? Let's learn together today!
Bicycles generally have two sets of brakes, one to control the front wheels and the other to control the rear wheels. If you want to control the bicycle in the shortest distance, the best way is to pull the front brake, the force control in the rear wheel just floated off the ground, the person and the car in the process of traveling have forward inertia, and the acceleration of gravity at the same time will form a forward and downward force, the braking action is by the friction between the tire and the ground, resist the forward force, the greater the pressure The greater the friction, so most of the friction comes from the front wheel at this time. On generally dry, flat roads, the front brakes provide maximum braking efficiency.
In addition to the front brake, the rear brake also has a great effect, and the rear brake will play a greater role than the front brake in the following cases
1, wet and slippery soft road: on the slippery road, the tire is easy to slip, if it is the rear wheel slippage, it is easy to restore the balance, if it is the front wheel side skating, you must use the rear brake to stop the car.
2, bumpy road: encounter the road surface is not usual, there may be a wheel jump off the ground situation, in this case, if the use of the front brake, may lead to the front wheel lock, so usually choose to use the rear brake.
3. When the front wheel is punctured: when the front wheel is punctured, the front brake must not be used, otherwise the tire may break away from the steel ring and the danger of overturning occurs.
4, front brake failure: excessive wear of the brake pad and other reasons may cause the front brake failure, in this case can only choose to use the rear brake.
There may also be times when the front and rear brakes are used at the same time, such as the following situations.
1, long straight downhill: not only the hand that has been pinching the front brake will be tired, but also the overheating of the front wheel may produce a flat tire. At this time, it is best to use the point brake method to make the front and rear brakes take turns, so that the heat generated by the brakes is divided into two rims and dissipated, so as not to accumulate heat and affect the tires. When it is necessary to decelerate rapidly, it is still necessary to use a front brake.
2. Bending. Tires provide both grip and friction for cornering, while using front and rear brakes reduces the likelihood of wheel slippage. The sharper the bend, the lighter the brake, so control the speed before entering the corner. Do not use the brakes when cornering is urgent.
3. Bicycles with a long body or a very low body. For example, tandem cars or recliners, their geometry makes it impossible for the rear wheels to. The simultaneous use of the front and rear brakes of this car provides maximum braking force.
