Mountain biking is riding in the mountains, so mountain climbing has become an indispensable part of this sport. In addition to having a strong body and sufficient strength, correct riding skills also help drivers successfully deal with various mountain roads. Whether the bicycle can travel forward or upward depends on two key factors: one is the operation and strength of the power transmission system, and the other is the friction between the wheel and the ground. The operation and strength of the power transmission system is directly related to the physical strength and strength of the driver. Friction is related to riding skills, the type of bicycle tires, the position of the rider's body center of gravity and tire pressure.
The hillside is steep, the gravel road is soft and the friction is small.
The secret to keep the bicycle moving forward in the process of crawling is to make the rider's weight distribution, riding posture, strength, pedaling mode and the coordination between the best routes reach the best state.
When climbing steep and difficult slopes, some drivers are used to standing, which is more effective on hard ground with high friction, but in typical cross-country sports, the situation is quite different. At this time, cycling skills show its important role. The driver should try to move the body center of gravity to the rear of the seat, increase the pressure on the rear wheel, and thus increase the friction. However, it is easy for the front wheel to tilt up, it is more difficult to ride a bicycle, and it is also possible to fall backwards. If the center of gravity moves forward, the front wheel will not leave the ground, but the rear wheel may idle in place on the soft ground, making it difficult for the bicycle to move.
After considering all the above factors, the rider should adjust the position of the body center of gravity at any time according to the terrain. In order to achieve the best distribution of body weight, the rider's ass may just sit gently at the front end of the seat from beginning to end.
In order to drive the bicycle forward, the driver must continuously and smoothly transfer energy to the power system. If the force is too large, it may reduce the friction; If the force is too small, it may slow down the speed or cause the bicycle to stop. If the pedal is slammed up and down, instead of making the pedal move smoothly in a circle, the wheels will slip and idle in place because of the reduced friction with the ground.
Technical crawling
Various rules applicable to climbing steep slopes are also applicable to technical climbing. The only difference is that technical climbing does not require the rider to find a suitable riding route, as long as the rider can find a way between rocks, ravines or abrupt roots. Look at the ground within 5 meters ahead and choose the best lane. However, once the cycling route is determined, don't change it at will.
Long distance climbing
All kinds of riding rules apply to this kind of sports, but the specific rules depend on the difficulty and slope of the terrain. However, in order to be able to ride the whole course, the driver must do what he can and choose the appropriate speed and gear ratio. To conquer all slopes, drivers need to be strong, have enough strength, master considerable riding skills and adopt a correct attitude towards sports.
At first, some drivers were not strong enough to cope with certain slopes. However, with enough exercise, this situation can be improved. At the beginning of training, don't aim at the whole mountain, start from where you can cope, and then gradually transition to a more difficult step. In addition, remember, as long as you can achieve your goal, don't care when. If you are confident that you can conquer most slopes, you need to consider speed.
How to restart the bike on a soft steep slope?
Once the bicycle stops on the slope, it is not easy to start again. The driver must get off the bus, take a few steps forward, or take a few steps back and choose the right place to start again. The place you choose must be flat and have high friction, such as relatively flat rocks. At the same time, choose a gear whose transmission ratio is not too large, as long as it can cope with the current situation. If it is too big, the bike may break down. After choosing the gear, pedal the bike with the most used and powerful leg and hold down the brake at the same time. When the bicycle starts to move forward, put the other foot on the pedal, then steadily exert force and accelerate until it returns to the scheduled lane. Another better way is to park your bike diagonally in the driveway and turn the front of it over after starting.
Mountain bike downhill
Just relax。 If the limbs are stiff when riding a bicycle, not only will the cyclist shake from side to side, but the bicycle may also bump up and down. The driver should take a squat posture, with his legs and arms slightly bent and his hips gently sitting on the seat. Doing so can not only improve the speed, but also make the driver feel very comfortable, thus better controlling the bicycle. The driver's body center is slightly backward and falls on the rear end of the seat, which will increase the activity space of the frame and absorb certain impact force. You can also lower the seat by about 3 to 4 centimeters and increase the operating space. Keep an eye on the driveway, not the obstacles on the road.
High-speed short-distance downhill
Riding on this slope, the rider can see the bottom of the slope at a glance and can choose a direct route to the bottom of the slope. This is very useful, because in the whole downhill process, as long as the terrain allows, the bicycle can reach the fastest speed and accumulate the maximum momentum for rushing to the opposite slope. Doing so can maximize the preservation of strength and improve the average speed of the whole process. In this sport, the driver's primary goal is to choose the appropriate downhill route, catch up with the route on the opposite slope, and then stick to it.
Long distance downhill
Long-distance downhill, that is, you need to choose a terrain that is easier to deal with, and you need to master the corresponding riding skills. In this process, it is impossible for the driver to see the bottom of the slope from the top of the slope at a glance, so he should keep walking and observing. Look ahead. According to the speed of cycling, pay attention to the ground 15 meters ahead, at least pay attention to the place where the terrain allows the line of sight to reach. Choose the route you want to take, and then ride along this route, but don't forget to adjust it at any time according to the change of terrain. It sounds a bit difficult, but after riding for a while, there won't be much problem on the base. At the beginning, you should choose a speed that you can certainly handle more easily. Don't push too hard or too fast, or you will soon feel exhausted, which will lead to crashes and other accidents.
Technology downhill
Don't go downhill too fast until you know the terrain ahead. Drivers need to be familiar with obstacles on the way in order to make a safe detour. Even if I am familiar with the present terrain, I haven't ridden here recently, especially the bad weather recently. Drivers should observe the terrain carefully to avoid more dangerous accidents.
Professional downhill athletes usually ride a lap in the driveway in advance, trying to deal with obstacles until they find the best riding route, and then race with confidence. A good suggestion is to have a general impression of the whole race before the start of the race, and remember all the relevant skills and tips we have talked about here. Spare protective facilities, such as special helmets, gloves, protective clothing, protective shorts, etc., must be brought when performing technical downhill sports.
Zigzag downhill
Zigzag downhill movement usually includes a series of short downhill, but does not include climbing the opposite slope again. Therefore, drivers must control their speed so that they can cope with sharp turns and other unexpected situations. The most popular riding skill is to draw a curve on the way before exercise, but the distance of each section should be considered in order to brake in time and turn smoothly. Braking in corners is absolutely not allowed. On the one hand, it will seriously affect the ability to deal with difficult terrain; On the other hand, the shift of the center of gravity may throw the driver out of the corner, thus increasing the difficulty of crossing the corner at a higher speed.
