7. Chain / Transmission Adjustment

(1) The bike gear is not consistent with the position of the chain, and the chain may be easy to jump or fall off.
Gear 1 is the highest gear, and Gear 7 is the lowest.
If the gear shift is set at a high gear, but the chain is in low gear and does not change to the corresponding position, this is because the gear shifter line is too loose. You can fine-tune the screw on the derailleur (at the rear wheel) by rotating it counterclockwise to tighten the line.

If the above method fails to solve the problem, we advise you to go to a professional bicycle shop for inspection and repair to ensure safety and efficiency.
