The seat height should be set based on your personal preference. The initial seat position
can be set by first placing the ball of your foot on the pedal with the crank arm in its lowest
position. In this position, your leg should be almost fully extended with a slight bend in your
knee. The proper seat position is important to avoid strain and potential injury during riding.
Consult a trusted, reputable bike mechanic or contact Flyer customer service for any questions
related to the seat position and fit of your bike.
A. Open the quick release lever located under the saddle. Rotate the lever fully open to allow
the seat post to slide easily.
B. Move the seat up and down by sliding the seat post in or out of the seat tube. Set the saddle
to the desired height based on rider preference. Ensure that the seat post does not extend
beyond the “minimum seat post insertion” markings on the seat post.
C. Close the quick release lever fully against the seat post tube. This should take some force to
ensure the seat post will stay firmly in place while riding.
