Why do we rarely see Internal gear hub（bulit in motor&e-shift）
The E-bike manufacturer has always had a tricky problem with how to install the motor onto the rear wheel hub, as the internal transmission has already been installed on the rear wheel hub, occupying the position of the E-bike rear wheel hub motor. Therefore, if E-bike manufacturers want to use an internal transmission, they can only use a mid mounted electric motor mounted on the eBike's five way central axle (the middle of the E-bike body).

Nowadays, a mid mounted motor, belt, and internal transmission are becoming standard equipment for high-end E-bikes models. When promoting high-end E-bikes, the E-bikes brand will include the internal transmission brand in its name and prominently list "easier to clean and maintain without maintenance" and "better riding experience" in the text. The reason is that the maintenance cost of bicycles equipped with external transmission may be higher than the overall vehicle price. Repairing an external transmission in Germany costs 100 euros and requires an average of 1-2 maintenance services per month. By comparison, the appearance of the internal transmission is very simple, with all components placed in the flower drum (note: placed at the rear wheel hub of the bicycle, as shown in the figure below). In this way, the chain of the vehicle body can be replaced with a belt, and the gears inside the transmission will not be exposed to the outside, saving the trouble of daily maintenance.
High Speed Motor 3-speed Internal-gear Hub can effectively solve the above problems. LoFandi integrates the motor with the gearbox, and the wheel hub motor can also be paired with belt transmission like a mid mounted motor, which will increase the lifespan and stability of the gearbox and reduce costs. On the price side, a wheel hub motor costs $100, and the eBike with a wheel hub motor usually means a cost-effective price range, but it currently accounts for the majority of sales in the market; If the eBike is upgraded with a mid mounted motor and internal variable speed, the price per bike will be basically higher than $2000 because the internal structure of the mid mounted motor is more complex, and the cost of one motor will increase by $200-400; Breaking free from upstream supply side restrictions means that eBike manufacturers have the opportunity to target the mid-range consumer market with models equipped with wheel hub motors.

Through three variable gears, riders can easily switch between lower gears for climbing and higher gears for faster speeds on flat terrain; The control system will control the transmission to achieve automatic shifting based on sensing signals such as torque and step frequency. The rider can also change gears autonomously by pressing buttons on the joystick.
