How to buy a electric mountain bike? (1)
Electric mountain bike racing has become a hobby of more and more young people. In order to ensure safety, we must be careful in the purchase of mountain bikes. The maintenance of the bikes is also very important at ordinary times. As a bicycle for mountain cycling enthusiasts, mountain bike is different from ordinary bicycles in its workmanship and material, so what details should we pay attention to?
An important part of the mountain bike, according to the structure of the hard frame, soft frame (after shock absorber frame), the quality of the frame determines the quality of a car. The current frame from low to high material is basically high carbon steel - aluminum alloy - carbon fiber - titanium alloy. In the choice of frame must consider their own economic conditions, although expensive things we all like, but suitable for their own is the best. In addition to the price, the size of the frame is also the choice of time must be carefully considered, once the frame is determined, the size of the car is basically confirmed oh. The proper frame should be the rider cross crotch between the top tube to have about 10cm distance. If you're only riding on the city's wide streets, it doesn't hurt to have a bigger size. You can't just stick to the numbers in the sales brochure. You need to actually step on the upper tube to confirm it.
Mountain bike front fork
Mountain cross-country bikes are generally equipped with high-performance front shock absorber system, the choice of front shock absorber fork is also very important, the quality of the front fork shock absorber determines whether you can get a good feeling in the riding. The front fork, like the frame, comes in a variety of materials from high-carbon steel to titanium alloy, as well as spring (which is common in low-end cars), oil pressure and air pressure. Oil pressure damping is increased on the basis of spring damping oil damping, can adjust the spring rebound speed, but also has locking function, in flat road and climbing has a great advantage. Pneumatic shock absorption, through positive and negative air pressure to achieve shock absorption, is the price is high, mainly used in high-end cars. In these forks, our common shock absorption methods are spring and oil pressure shock absorption. The size of the stroke (refers to the distance that the shock absorber or shock fork moves because of the shock absorber) is generally 40 to 120 mm, which can be selected according to different needs, so that the mountain bike can safely pass through no matter what complex ground conditions.
Mountain bike tires
Thick tires and strong grip are the main characteristics of mountain dirt bikes. The quality of the tire determines the grip of the vehicle and the wear resistance of the tire during riding. At present, the main bicycle tire brands in the market are mainly Jianda and Chaoyang. Of course, there are some brands of original tires are also very good. Tire material, pattern and grain arrangement, shape and depth determine the performance of the tire, in different road surfaces should choose different tires.
