ADJUSTING THE SEAT HEIGHT

 

Use the quick release lever to free the seat post and pull upwards or push downwards to reach 
desired height. 

Notice: 

Ensure seat post and seat are properly adjusted before riding. Do not raise the seat post 

beyond the minimum insertion marking etched into the seat post tube. If your seat post projects 
from the frame beyond these markings, the seat post or frame may break, which could cause you to 
lose control and fall. Prior to first use, be sure to tighten the seat clamp properly. A loose seat clamp 
or seat post binding bolt can cause damage to the bicycle or can cause you to lose control or fall. 
Periodically check to make sure these the seat clamp is properly tightened. 

 

RIDER COMFORT

 

To obtain maximum comfort, the rider should not overextend his or her arms reach when riding. In 
order to obtain the most comfortable riding position and offer the best possible pedaling efficiency, 
the seat 

height should be set correctly in relation to the rider’s leg length. The correct saddle height 

should not allow leg strain from over extension, and the hips should not rock from side to side when 
pedaling. While sitting on the bicycle with one pedal at its lowest point, place the ball of your foot on 
that pedal. The correct saddle height will allow the knee to be slightly bent in this position.
