How to Adjust a Bike Saddle (Seat)

If sitting on your bike feels uncomfortable, especially on longer rides, or if you’re finding it difficult to pedal, your seat may have shifted and may no longer be at the right height or horizontal position for you.

How to Check Seat Height

Have a friend hold the bike in place as you sit on it and pedal backward: if you can extend your legs comfortably to reach the pedals and your bottom feels fine, the seat height and position are okay. If not, you need to change the seat position or seat height.

How to Adjust Seat Height

To adjust seat height (the vertical position of the seat):

Measure the seat’s current height with a tape measure.
Loosen the quick release or bolt that holds the seat post in place.
Move the seat up or down by pulling it straight up or pushing it down until it’s at the right height for you. If you have trouble moving the seat, try dripping some lubricant onto the seat post and then try again. If the seat still won’t move, ask a bike mechanic for help.
Tighten the quick release or bolt at your desired seat height.
Repeat the test in “How to Check Seat Height” above to see whether the new seat height fits you better.

How to Adjust Seat Position

To adjust seat position (the horizontal angle and front-to-back position of the seat):

Use pliers or an Allen wrench to loosen the bolt(s) on the seat’s bottom that hold the seat in place.
Move the seat forward or backward, or tilt it up or down to adjust its horizontal angle.
Tighten the bolts.
Test the seat position with a short ride. Make further adjustments if necessary.

A wobbly or loose saddle can be dangerous. If you lack the strength or leverage to tighten the seat bolts all the way, have a friend help you tighten them.
