Adjust the Saddle Height

The saddle position can be tested when you sit on the saddle with your heel on the lower pedal. 

Before performing the adjustment of the saddle position, a saddle height test is needed.

 

If your leg is straight and your knee is fully 

extended, it indicates that the saddle is in 

an appropriate position.

 

If your leg is bent at the knee, it indicates 

that the saddle should be adjusted up. 

 

If you cannot reach the pedal, it indicates 

that the saddle should be adjusted down. 

To adjust the saddle position, follow the steps below.
1. 

Loosen the seat post clamp with an M5 

Allen key.

2.  Slide the seatpost in or out of the seat tube.

To avoid damage to seatpost or ebike 

frame, do not position the saddle lower 

than the minimum insertion line on the 

seatpost.

If you are uncertain/unsure of/in doubt 

about the saddle position, seek help from 

a qualified mechanic.

3. 

Tighten the seatpost clamp with an M5 

Allen key. Ensure that the clamp is firmly 

tightened.

4. 

If the saddle position needs a bit more adjusting, repeat steps 1 to 3

.

WARNING

!

 

With the seatpost fully compressed and the saddle in the rearmost 

position, the rear tire may rub the saddle. To avoid this situation, it is 

recommended to adjust the saddle up and forward.

 

After any saddle adjustment, be sure that the saddle adjusting 

mechanism is properly tightened before riding. A loose seatpost 

clamp can cause damage to the seatpost, or can cause loss of control 

accidents.
