In order to make the new Emma a super e-bike that can be ridden comfortably in all kinds of terrain and make its dual suspension fully functional, Roll-Road boasts a hydraulic spring plus air cylinder damping system for the rear suspension.

 Hydraulic spring plus gas cylinder damping is a kind of vehicle damping system, commonly used in some off-road vehicles, racing cars and other high-performance cars and motorcycles, the main damping effect is to reduce the bumps and vibrations during the vehicle driving process.

 The hydraulic spring and cylinder damping system can provide better damping effect than the traditional spring damping system, because it can adjust the spring pressure according to the road conditions and vehicle speed and other conditions, thus providing better vehicle stability and ride comfort.

 In addition, hydraulic spring plus gas cylinder damping has the ability to self-adjust, automatically adjusting the damping effect according to the vehicle's load and driving conditions.

 Similarly, the front shock absorber of electric vehicles using hydraulic shock absorbers has the advantages of reducing vibration, improving stability, increasing grounding, reducing wear and tear and good adjustment performance."
