E-bikes have their own unique engineering and performance characteristics and though newish on the scene for mountain biking, a stream of ebike-specific hardware is flowing steady to our aftermarket parts shelves and also fresh out of our bike manufacturers. Anytime we see e-bike specific parts that make ebike riding more fun, we like it.

SRAM developed the EX1 drive system as the "world’s first drivetrain system specifically developed for the unique demands of the E-MTB".

Built on the SRAM 1x™ technology platform, the center of the system is the EX1 cassette, which allows optimal steps between cogs for more purpose-driven shifts and providing the best gear range for center drive motor E-MTBs such as with BOSCH Performance and Performance CX.

"Each EX1 component is engineered to perfectly complement the system, and the result is quiet operation, intuitive shifting, increased battery life and greater durability. EX1 opens the door to a brave new world of mountain biking."

We'll be seeing this system on a number of the higher end
Haibike, KTM, CUBE and MOUTACHE ebikes.
