Road bikes are used on smooth roads. Due to the low resistance of smooth roads, road bikes are designed with greater consideration for high speeds. They often use down-bending handles that can reduce wind resistance, and narrow high-pressure and low-resistance tires. The gears are higher, and the wheel diameter is larger than that of ordinary mountain bikes. Because the frame and accessories do not need to be strengthened like mountain bikes, they are often lighter and more efficient when riding on the road. Because the frame does not need to be strengthened and often uses a simple and efficient diamond design, road bikes are the most beautiful bicycles.
The length of the bicycle shall not exceed 185 cm, the width shall not exceed 50 cm, and the weight shall not be less than 6.8 kg. The length of the seat should be between 24-30 cm, the distance between the central 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.
The advantages of road bikes are low resistance, faster riding, lighter weight and less effort, low resistance, large gear ratio, fast speed under the same pedaling frequency and power, and light and labor-saving riding for transportation. The combination of people and vehicles is high and easy to control. It is also an excellent sports equipment.
