Should I use the front brake or the rear brake?
Because your bike has two sets of brakes, one for the front wheels and one for the rear wheels. In order for you to stop your bike safely, you must be well-versed in using the brakes.
The traditional saying is: use the front and rear brakes at the same time. The theory is very useful for a beginner who is not yet proficient in cycling skills, but if you can't get past this stage, then you will not be able to master the professional skills of cleverly controlling the bicycle.
Usually, the best way to stop the bicycle in the shortest distance is to pull the front brake to the extent that the rear wheel just floats off the ground, because the moving human body and the bike have forward inertia, and the acceleration of gravity is downward. The two forces act at the same time to form a forward and downward resultant force. The braking action relies on the friction between the tire and the ground to resist the forward force. The greater the pressure, the greater the friction, so most of the friction comes from the front. wheel. Because the rear wheel is floating, the rear brake has no effect at all. On soft or slippery roads, or when the front tire blows out, make full use of the rear brakes, but on generally dry, flat surfaces, the front brakes will always provide the greatest braking effect, both theoretically and practically. Once you learn to use the front brake properly, you will be a safe rider.
You must be worried, won't this result in a forward roll?
It's possible, but only for riders who haven't learned to adjust the bike front brake force. Some riders who rely on the rear brake to stop their bicycles will have an epiphany after an accident: in an emergency, they instinctively grab the very unfamiliar front brake because of panic, in order to increase the braking force. The result is often a fall An upside-down onion, so embarrassed. Some people also believe that the reason for the "forward rollover" is not because the front brake is too strong. Still, because the front brake is used vigorously without using the strength of the arm to resist the deceleration force, the bike is stopped. The rider continues to rush forward, Until his ass "sits" on the handlebars and "rides" people on a different vehicle. This doesn't happen to people who only use the rear brake, because when the rear wheel leaves the ground, it has no braking effect due to the loss of friction, but the cost of using only the rear brake is that the braking distance increases to that of using only the front brake. So, it is not safe for riders who often ride fast bikes to rely on the rear brake alone. Remember, during emergency braking, use your arms to firmly support the ears to avoid forward flipping. The key is to push your butt back as far as you can handle it, don't stick to the seat cushion - try to move your weight back as much as possible. This technique works for a variety of braking conditions, whether it's using the front brake only or using both front and rear brakes.
