Guidelines for Seat Height
While sitting on the bike with one pedal at its lowest point, place the ball of the foot on that pedal. At the correct seat height, the knee should be slightly bent in this position.
The seat height should be set correctly in relation to the rider’s leg length to obtain the most comfortable riding position and offer the best possible efficiency of pedaling. The correct seat height should prevent leg strain from overextension and ensure that the hips do not rock from side to side when pedaling.
DO NOT raise the seat post beyond the minimum insertion marking that is etched into the seat post tube. If the seat post projects from the frame beyond these markings, the seat post or frame may break, which could cause a rider to lose control and fall. Ensure that the minimum insertion markings on the seat post are inside the seat tube of the frame.
Adjusting the Seat Height
Follow these steps to adjust the seat height:
- Open the quick-release lever by swinging the lever open and outwards to about 180 degrees. Loosen the adjustment nut opposite the quick release lever by a small amount.
- Move the seat up or down by sliding the seat post in or out of the seat tube. Set the desired seat height by moving it in small increments. Look at the nose of the seat from above to realign it with the top tube of the bike, if necessary.
- Tighten the adjustment nut opposite the quick release lever on the seat post quick release, and close the quick release lever by swinging the lever back about 90 degrees. The quick-release lever should require some pressure to close. After closing it, make sure that the seat cannot move up, down, to the left, or right.
