E-Drive 9

9-speed shifting system specifically developed for e-bikes

With the E-DRIVE 9, TEKTRO opens their latest product segment in the E-Bike Solutions category with a 9-speed drivetrain system for entry-level e-bikes.
The highlight: a 9-speed cassette where the smallest three sprockets – 11-13-16 – can be easily exchanged and a derailleur with a clutch mechanism for higher chain tension.

E BIKE SOLUTIONS: started in 2017 in response to the first customer requests for a more robust brake systems for e-bikes. The solution was the new 2.3 mm thick brake disc standard used in the TRP DHR EVO brake systems. In 2019, the new TRP shifting segment was launched with the DH7 and TR12 rear derailleurs. The valuable experience gained over the last three years has helped to shape the development of the TEKTRO ED9.
Again, the impetus came from customers, who were looking for a more robust and low-wear shifting solution, especially for entry-level e-bikes. The E-bike boom and COVID-19 are bringing an excessive number of beginner riders onto entry level E-bikes.
