Connex Chainrings for Bosch Gen2

Chainrings for Bosch Gen2 (Active & Performance Line) Engines

After your Bosch electric bike engine has been tuned, the pedalling cadence sometimes can get very high if you are driving at higher speeds. That means, if you ride at a speed of about 35 km/h (≈22mph) you have to pedal very fast – so fast, it isn´t pleasant anymore. Here we compiled some chain rings for Bosch Gen2 (Active & Performance Line) engines. Replace your old chain ring with another one with more teeth, and you will pedal much more relaxed at higher speeds. The chain rings are available in six different versions: 14, 15, 16, 17, 18, 19, 20 and 22 teeth. If your electric bicycle has a chain ring with 15 or 16 teeth, it´s advisable to buy some more chain rings with a higher number of teeth. Then you can always choose the most suitable chain ring according to your preferred way of driving.

Please note: If you want to change your chainring you need the Bosch Spider for Gen2 (Bosch Active / Performance) and ISIS crank puller. If you already got an appropriate crank puller you only need the Bosch Spider for Gen2.
