Bicycle roller is a professional indoor training equipment. By fixing the rear wheel of the bicycle on the rolling frame, the cyclist can practice riding indoors. A road roller usually consists of three rolling rollers, including one roller contacting the rear wheel and two supporting wheels. The cyclist only needs to install his bicycle on the roller and adjust the contact pressure between the roller and the rear wheel, and then he can start indoor training.

Bicycle roller can help cyclists to train indoors, so as to better keep fit, enhance endurance and improve riding skills. For those who can't ride outdoors, the roller can be a powerful tool for indoor training. In addition, rollers can provide a safer way than riding outdoors, reducing the risk of injury.

At present, there are many kinds of bicycle rollers on the market, including magnetic roller, fluid roller and direct-drive roller. Different types of rollers use different technologies and materials to simulate riding conditions. For example, the fluid roller uses the mechanism of oil wetting and sliding to adjust the contact pressure between the roller and the tire, thus providing more accurate resistance and more realistic riding experience. Direct drive drum usually adopts gearless design, which can better simulate the speed change of external environment. No matter which type of roller is used, the rider can choose the most suitable product according to his own requirements and conditions.
