On the role of electric bicycle shock absorbers.
First of all, we know a premise that when the vehicle is subjected to vibration and shock from uneven road surface, if these vibrations and shocks are transmitted directly from the wheels to the body, then the ride comfort and handling stability of the vehicle will be very poor, so the role of shock absorbers is reflected here.

Why do electric bikes need hydraulic damping? Are there any benefits?
The principle of hydraulic damping is that when you press down, you are relying on the resistance of the spring to slow down the speed of pressure. But if you don't have a hydraulic system, the spring will always bounce back when it is pressed down. Bounce back if there is no resistance, it will bounce very fast, then press down without a cushion.

So what is the role of hydraulic fluid in it?
It bounces back, as long as the oil through a small hole, can be adjusted in the hydraulic spring inside the hydraulic shock absorber inside a hole in the flow, open this hole a little larger and smaller, it can control the speed of your rebound, so the hydraulic shock will artificially is to control your vibration frequency, so that you feel comfortable.

Overall, the hydraulic mechanical spring and hydraulic hysteresis system shock absorber will be a little better, but the cost will also be higher. Because there will be some parts inside including tubes, oil, oil seals, etc. Ordinary spring damping can be used when the damping is not very large. But electric bikes are usually more comfortable for people to ride, so they must use hydraulic damping, including rear wheel damping is also as far as possible to use hydraulic damping. The role of shock absorption is not only comfortable to ride, but also to the entire mechanical structure of the impact resistance will be greatly improved, which is conducive to extending the service life of the mechanical system.
