Bike Chain

The chain must maintain a slight sag to be able to switch be-

tween gears when shifting. It is important to make sure that the 

chain is the proper length, or the cycling performance will be 

affected negatively.
To determine the length of the chain, 

adjust the Back Fender to the lowest 

gear, the chain should sag 15mm or less 

(as shown to the right). If the chain sags 

more than 15mm, the chain is too long 

and must be shortened by the supplier to 

maintain the best cycling performance 

for your electric bike.

Damping System

The Damping system helps keep the tire buffer in contact with 

the ground when the electric bike is running on uneven road. 

This helps you feel more comfortable during difficult conditions.

Damping hardness can be adjusted by 

rotating the Damping Coefficient (as seen 

on the left), according to road conditions 

and personal preference. The Damping sys-

tem can be found on the Front Fork, please 

check Page 3 to locate it on the electric 

bike.

NOTE: Do not adjust damping while in motion. Be sure to test damping levels fully 

to match your preferences.

To adjust the damping, rotate towards the 

+

 sign to increase 

the damping hardness. Rotate towards the 

-

 sign to reduce the 

damping hardness.
