4, "mountain bike" in terrain

Understand the basic characteristics of various terrain to enhance self-confidence, but the driver needs to practice in drivers.

Stonehenge

Meet larger stones, best avoided, from next round. Want to jump over it, to see whether behind stone has enough space, whether born bicycle safety. If the bike at a slower speed, stone and more big, need special cycling skills. Considering the game close to slow speed when some stones, until the obstacle over again after speed. Also should choose power transmission ratio is big gear. General crankset and flywheel chooses medium.

Small stones

The so-called small stones, size ball size. But, bicycle riding on it. Therefore, be full of small stones terrain for all the drivers is a daunting challenge. Meet the terrain, control and brake are very difficult to bike, must grasp the corresponding control car skills.

A very important fact is perhaps we should not forget most. That is, in be full of gravel or cobble ground control bicycle in hard on the ground texture. Therefore, on the bus, drivers must loosen all over, according to the circumstance, flexible, not "handle" bicycle, but "guide" from a bicycle is hard to compare the place where a hard. To be successful, riding process must choose one place, then blunt past, aim. If you want to change the direction of cycling, driver just need to take the barycenter moving from one side of the body to the other side, then gently push bicycle in a certain direction.

The habit of braking also needs to be changed. Hill, body weight, rear back to gain greater friction. Before using too often, brake, especially when turning. Don't make the friction between front and ground is too big, to maintain the proper. After using as much as possible, with less former brake. Otherwise, the bicycle into rocks or cobble can skid. At this time, not only can slow, instead of bicycle, thus accelerating lose control.

ravine

Through to the ravines, as far as possible to maintain level. Bicycle If you are stuck in a ditch, light person can hit a bike, the person can damage. Small groove can jump over the past, if the ditch is wide, need to think another way. If the width of the ditch, can also ride from the past or. Front GouYan encounter when the body weight, the left front back and then push front to ditch. Wait to opposite of slope, in front and brought out from the ditch. Body weight forward, to continue the stirrup. This is a skill and across the skills of the big stone. However, here to do not jump from obstructions on past, but from or out.

By water erosion gully and V type is relatively difficult terrain. This communication ChangKuan 50 centimeters, also in 50 centimeters. The simplest way from the ditch above only carry bicycle. Besides, there are many methods. Best method is to use in front when crag to balance stunt. When the rear body gravity met or slightly forward, and continue until the stirrup, out of or.

If the bicycle was stuck in the trench, need to find a place to ride out the little gradient, also can use side qi fa jump out from the groove. However, if the ditch is too deep, slowly, bicycle to slow climb out later.

The sand

The sand often allow the driver to tremble, but with the terrain of skills and covered with sand and gravel performance of terrain. Meet the terrain, bicycle front easily trapped in the sand, the driver also hard to control the direction of the bicycle. This is the bike in the common techniques can correct operation of the following:

With the fastest way possible target location near the sand, and moved.

Smooth force, keep speed of the stirrup. From the comparison of loose sand is thick, be like in through the same surfing, gently "prey" in the past. Tip: don't forget, other cyclists and motorcyclists through comparison, riding up where your lungs.

roots

Roots for many drivers, it is evil, especially in the slope, the driver must be mix. In such cases, or is carried the bicycle, or use front from the ground up front, balance, followed by special focus from books, let the rear roots above roll over. Please remember not to increase power transmission system, otherwise, it will reduce the friction pressure.

log

Like stones to treat logs, use the same cycling skills. The only difference is in the rear of logs, met the moment, must assure front has fallen on the other side of the log. At this time, the body must not be too. Compare the logs can use qi fa jump technique jump.

Across the water

The water from a very exciting place through the affirmation, but to do so before the water depth, a see whether there is water stone or pit. Even very understanding the terrain, the links are not may be omitted. If you don't understand, or have long time no pass, better slow down, or simply walking past off. Use the famous sports authorities dropped the abbot's words: "because of the water and mud speed and braking effect is bad, and carry on the bike, the best bike from water, walking through the wet shoes, still can do." However, if the very confident, think oneself can safely through, then let courage be blunt past, but must be put back the body gravity.
