Batteries are one of the most valuable components on an electric bike. They often make up 1/3 of the total price of an e-bike. There are several parameters that affect the range of an e-bike: type of terrain, tyre profile, rider weight, assistance used, etc. you can read more in our blog.
The advantage of Bosch batteries is a very high quality BMS (battery management system). Thanks to temperature and voltage sensors, the BMS can switch individual cells on and off to avoid a significant reduction in range and to ensure the longest possible life of the battery itself.
Bosch motors are among the best in the world of electric bikes. Motors from the German manufacturer stand out for their reliability and quality workmanship. Bosch Performance Line CX (from MY 2022, Smart System is the motor with the maximum 340% boost. It uses a larger (38t) chainring for better power transfer. This motor is very sporty, so it is mainly designed for mountain bikes. The new feature here is the possibility of adding the ConnectModule, which will offer new anti-theft features as well as a connection to the eBike Flow app.
