​​Product Description:

Hardware Requirements

The total length of the bicycle should not exceed 185 cm, the width should not exceed 50 cm, and the weight should not be less than 6.8 kg. The length of the seat should be between 24-30 cm, the distance between the center axis and the ground should be between 24-30 cm, and the diameter of the front and rear wheels of the bicycle must be the same. Wheels have a maximum diameter of 70 cm and a minimum of 55 cm. The bicycles used should be dead flywheels, and no shifting devices and brakes should be installed.

Race Track

Mountain bike races range from 40-50 km. Among them, the flat road section shall not exceed 15%, and the rest shall be uneven road sections. The route usually consists of high-speed downhill sections, climbing sections, country sections, gravel sections, forest sections and short asphalt sections.

There is a sign every 1 km on the track to indicate the number of kilometers from the finish line. The size of the road sign is 20 cm wide and 40 cm long, and it is placed 1.5 meters from the ground. Road signs should accurately indicate the course of the race and subsequent changes in road conditions, as well as intersections and all areas of potentially hazardous situations.

The starting section must be wide enough for the driver to start safely. Before and after the finish line, there should be a long enough straight road and a wide field of vision to provide a safety guarantee for the finish sprint and the buffer after the sprint.

Frame

Because mountain bikes are more laborious to ride, the frame of mountain bikes is correspondingly smaller than that of ordinary bicycles. This structure takes into account the characteristics of the off-road bicycle movement, and the bicycle is more convenient to operate on different grounds.

The material, construction, and design style of the frame are very important in making a high-performance, safe and reliable bicycle, because the bicycle frame needs to withstand shocks from various reasons.

The difference between mountain bikes and ordinary bicycles

Mountain bikes differ from other bikes primarily in that they incorporate features aimed at increasing durability and improving performance in rough terrain. Most modern mountain bikes have some kind of suspension, 26, 27.5 or 29 inch diameter tires, usually between 1.7 and 2.5 inches in width, and a wider, flat or upwardly-rising handlebar that allows a more upright riding position, giving the rider more control. They have a smaller, reinforced frame, usually made of wide tubing. Tires usually have a pronounced tread, and are mounted on rims which are stronger than those used on most non-mountain bicycles. Compared to other bikes, mountain bikes also use hydraulic disc brakes. They also tend to have lower ratio gears to facilitate climbing steep hills and traversing obstacles.

A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces.

Mountain biking is a sport of riding bicycles off-road, often over rough terrain, usually using specially designed mountain bikes. Mountain bikes share similarities with other bikes but incorporate features designed to enhance durability and performance in rough terrain, such as air or coil-sprung shocks used as suspension, larger and wider wheels and tires, stronger frame materials, and mechanically or hydraulically actuated disc brakes. Mountain biking can generally be broken down into five distinct categories: cross country, trail riding, all mountain (also referred to as "Enduro"), downhill, and freeride.

This sport requires endurance, core strength and balance, bike handling skills, and self-reliance. Advanced riders pursue both steep technical descents and high incline climbs. In the case of freeride, downhill, and dirt jumping, aerial maneuvers are performed off both natural features and specially constructed jumps and ramps.

Mountain bikers ride on off-road trails such as singletrack, back-country roads, wider bike park trails, fire roads, and some advanced trails are designed with jumps, berms, and drop-offs to add excitement to the trail. Riders with enduro and downhill bikes will often visit ski resorts that stay open in the summer to ride downhill-specific trails, using the ski lifts to return to the top with their bikes. Because riders are often far from civilization, there is a strong element of self-reliance in the sport. Riders learn to repair broken bikes and flat tires to avoid being stranded. Many riders carry a backpack, including water, food, tools for trailside repairs, and a first aid kit in case of injury. Group rides are common, especially on longer treks. Mountain bike orienteering adds the skill of map navigation to mountain biking.
