26 Inch Bike

Speaking of a 26 inch bicycle, I'm sure everyone is familiar with it. The bicycle I'm introducing today is a bicycle independently developed, designed, and produced by our company. This Lithium Battery Electric Bicycle is different from a regular bicycle. This Electric Bike is equipped with an Ebike Motor and a Lithium battery. Some mopeds are equipped with rear wheel hub motors, some are mid mounted Ebike Motors, and very few are front wheel hub motors. Lithium Batteries are installed in the lower tube position of the moped to provide a continuous source of power and energy support for the lithium-ion E Bike.The method of dividing the size of a car varies from person to person. Here, 26 inches refer to the wheels of a lithium-ion bicycle and not the frame. If the size is divided according to the bicycle frame, it can be divided into 15 inches and 17 inches.The method of dividing the size of a Bicycle varies from person to person. Here, 26 inches refer to the wheels of a lithium-ion Electric Bicycle and not the Bike Frame. If the size is divided according to the Bicycle Frame, it can be divided into 15 inches and 17 inches. The most important frame part of a bicycle is the frame, which directly affects the classification criteria and size of an Ebike.
