Mountain bike
Mountain biking originated in San Francisco, USA in 1977. Designed to ride in the mountains, usually with a transmission that can be changed to save effort or fast gears, some will install shock absorbers on the frame, part of the tires are chocolate treads to facilitate the road without paved bicycle surface Ride. The dimensions of mountain bike parts are generally in imperial units. The rim is 24/26/29 inches, and the tire size is generally 1.0-2.5 inches. The frame size is also in English units, such as 14″, 17″, 19″ to indicate the size of the frame.
It is divided into many categories in detail, and the one we commonly see is generally the xc category. Variable speed, good tire grip, suitable for off-road, shock absorption system to reduce bumps. The overall strength is greater and the impact resistance is strong. Compared with ordinary bicycles, it is less likely to be damaged when riding hard.
The material, structure and design style of the mountain bike frame are very important for manufacturing a high-performance, safe and reliable bicycle, because the bicycle frame needs to withstand the impact caused by various reasons.
All-mountain bikes are a type of mountain bike, weighing approximately 14 kg to 16 kg. They have longer shock absorbers and are heavier than XC bikes.
