4. E-bike Tuning Instructions
4.2. Derailleur Tuning:
The principle of derailleur tuning: some e-bikes have a front and rear derailleur - some models only have one at the rear. For e-
bikes with both, adjust the rear derailleur first and then adjust the front derailleur.
Tuning the rear derailleur:
A) Adjust the upper limit bolt with the chain in the smallest chainring at the back so that the chain cannot move past the smallest
chainring.
B) Shift the chain into the largest chainring at the back.
C) Adjust the lower limit bolt so that the chain cannot move past the largest chainring.
