Without Shimano and without Sram: You can also shift with Tektro
The E-Drive 9 combo is specially designed for use on e-bikes. There are nine gears on board and, as a highlight, the three wear-intensive, smallest sprockets (11, 13, 16) on the cassette with 11-46 tooth gradation are interchangeable. As befits today, the rear derailleur has a clutch for increased chain tension. A gearshift is also included, which shifts a maximum of three of the nine gears in one go.
