This Mountain E Bike is different from ordinary mountain bikes. It is an improved mountain assisted Electric Bicycle that looks very similar to ordinary mountain bikes from the outside, but its internal structure is fundamentally different from ordinary mountain bikes. Firstly, we installed a mid mounted Ebike Motor with assistance function at the foot position, which integrates torque sensing and speed sensing. Upon closer inspection, its Bike Frame also differs . It is evident that the position of the lower tube of the Bike Frame is slightly wider than that of a regular bicycle. This is because at this location, we have installed a Lithium Battery that can maintain its long-distance range. The 11 speed electronic control system is like the human nervous system, allowing it to move freely and agilely. The color tone of the entire vehicle frame is mainly black , which gives it a more dignified and atmospheric appearance.
