Why are electric road bike faster than electric mountain bike?
Electric road bike and electric mountain bike are different in basic design. All electric road bike designs can be said to be prepared for speed. And electric mountain bike need to consider many issues such as off-road performance, passability, and body firmness.
The frame of all sports electric bikes has three metrics: rigidity, weight, and strength. Because electric mountain bike adapt to many types of road surfaces, these three indicators must all be considered, while electric road bike are more rigid and lightweight. Road bike are usually slender (some TT frames look thicker, streamlined, but actually very narrow and light), while mountain bike are stronger. The frame angle of the mountain bike is very particular, the hard tail and soft tail are very different, while the angle of the road bike is similar. Electric mountain bike have thicker axles, while road bike have more refined axles. At present, with the use of manufacturing technology and high-tech materials, it is difficult to find any similarities between the two frames except for the basic structure.

3. Braking system.
Electric mountain bike mostly use gear tires or semi-smooth tires. And road bike are basically bald tires. The size of mountain bike tires is much larger than that of road bike. In terms of tire pressure, the high tire pressure requirements of road bike ensure a smaller tire contact area and reduce friction.
5. Shock absorption.
Frame and shock absorption are the two basic elements that distinguish electric mountain bike from electric road bike. Electric mountain bike have different shock absorption between hard and soft tails, while road bike rely entirely on human body shock absorption, and the entire body does not have any shock absorption parts. Equipped with shock absorption can improve riding comfort, and at the same time, shock absorption also releases force. Shock absorption is also a very heavy part.
In general, in terms of frame, shock absorption, brakes, and wheels (some road wheels can be light to the point of extreme abnormality), electric road bike are much lighter than electric mountain bike. Generally, it is not a big problem for a road car to be a few kilograms lighter than a mid-range car. Some people may say that these few kilograms of weight are made up again. This statement is correct in terms of total weight, but the reduction in the weight of the car is the most obvious manifestation of the acceleration performance.
7. Riding posture.
To put it simply, electric road bike are ridden on the tummy, and some will wear helmets similar to the heads of the opposite sex to increase the overall streamline. The riding resistance of electric mountain bike is not so small.
Finally, the mountain bike to be compared with the road bike should be a hard tail bike without rear shock absorber, and the whole bike has only front fork shock absorber. As for the soft tail, it is also equipped with a shock absorber on the frame. The bike has a very high shock absorption performance. This kind of bike is used to play downhill (DH), which is an extreme sport. This kind of bike can’t ride at all speed.
