Anonymous users2024-02-10When turning a mountain bike, it is best to reduce the speed to less than 15 km h. No trick is as safe as slowing down, mainly because everything changes quickly on the road, and the most important thing is safety.
When reducing the speed of the vehicle to make a turn, it is recommended that the user choose to brake on point instead of locking the brake. The way of braking is: (according to the general bicycle left side of the rear brake mode) slowly press the left brake, press it immediately after pressing, and then press it and repeat until the speed of the bicycle is completely lowered and you can safely turn the corner.
As for the technique, the user can choose to use the brake to lock the rear wheel (not have to be completely locked), and the body rolls sideways and follows the bicycle inertia forward with one foot (one foot lands to support and avoid falling) to form a "drift" feeling, and after cornering, because of inertia, the speed after the corner will be slightly higher than that of the user who directly decelerates and corners. It is possible to make perfect cornering without other vehicles. But this is very dangerous, because it is inertia forward, so there is no way to control the speed, if there are other vehicles passing at this time it is easy to form a car accident, so it is still very not recommended that users use skills to corner.

Legal basis: Article 57 of the Road Traffic Safety Law of the People's Republic of China Driving a non-motor vehicle on the road shall comply with the relevant traffic safety regulations. Non-motorized vehicles shall drive in non-motorized lanes; On roads where there are no non-motorized lanes, you should drive on the right side of the roadway.

Anonymous users2024-02-06The conditions for turning at a constant speed are due to gravity, support, and frictionWherein the gravity and support force are equal in magnitude, the direction is opposite, when advancing at a constant speed, the direction of friction force on the front wheel is backward, the direction of friction force on the rear wheel is forward, and the friction force of the two wheels is equal. When accelerating, the friction direction of the front wheel is backward, and the friction direction of the rear wheel is forward, and the friction of the rear wheel is greater than the friction of the front wheel.
Friction provides the centripetal force of the object's turn, and if the turning is too high, the friction is less than the centripetal force required by the object, and the object will slide in the radius direction. For example, when the car is driving on a normal road, the friction force is equal to the centripetal force required by the car, and when the car slides on the ice surface normally, if the speed is too high, the car will slide outward.
Bicycle constant speed turning characteristics
According to Newton's second law, the magnitude of the resultant external force is proportional to the mass of the object and the magnitude of acceleration, and the direction of the resultant force is the same as the direction of acceleration. That is, f is equal to ma. Rotten belts.
The motion done by an object that turns at a uniform speed can be seen as a circular motion with a uniform velocity. Uniform circular motion refers to the motion of an object along the circumference or arc of a circle at a constant rate of constant velocity magnitude. Uniform circular motion is a variable speed motion in which the direction of velocity changes from moment to moment.
Therefore, the body of the reed body in uniform circular motion has a centripetal acceleration directed towards the center of the circle, and the resultant external force experienced also points to the center of the circle. It is often referred to as the centripetal force. i.e. a is not equal to 0 and f is not equal to 0.
Only when a is equal to 0 is the object in equilibrium, at rest or in a uniform linear motion. The force experienced by the object in these two states is a balancing force. The force experienced by an object that turns at a constant speed is not a balancing force.
For example, when a bicycle is turning, the body should be tilted to increase the friction between the wheels and the ground, providing the centripetal force needed by the car when turning.
If you don't consider your actual use and capital reserves, of course, the higher the better. Generally speaking, the higher the number of shifts, the smoother the shifting, which can bring a comfortable, smooth feeling to the ride, and of course, the higher the speed. From nearly 1,000 yuan of DEORE to nearly 10,000 yuan of XTR, they are all 27-speed masterpieces. >>>More
Brother, you can get one! Cheap Giant variable speed mountain bike, I went to Giant some time ago to take a look, called Giant CTX26The 618 yuan sold in the physical store in Mianyang, Sichuan is a 26-inch steel frame, Shimano 18 transmission transmission, although it is a low-end transmission of SHIMANO, but it is much better than the transmission that I have never heard of in China! >>>More

If the landlord is an entry-level player, it is not necessary to choose the disc brake, and the maintenance and adjustment of the disc brake seem to require technology. Especially like the dunk600's bb5, many people say that this disc brake is chicken ribs if it is not tuned well, and it is very vegetable. The 770D seems to be SHIMANO's disc brake, I won't talk about it, the landlord can flip through some posts on the Internet. >>>More
Mountain bikes range from a few hundred to tens of thousands, depending on what your psychological price point is. Generally, novices can buy a 1500 to 2000 for beginners, and if you want to buy a Giant 670 690 or a Melada Warrior Duke, you can buy it in a physical store, don't consider online shopping. The car was sold in a partition, and the later adjustment and repair were bought locally. >>>More
