Why My Bike Seat Won’t go Lower?

Bike Seat Won't go Lower

There are two possible reasons why your bike seat won’t go lower. 

#1. Mechanical issue

Since moving your bike seat lower is done by lowering the seat post, it becomes impossible to do so.

‘A seat post forcefully inserted into its seat tube gets stuck and refuses to move. The forcefully inserted seat post may even cause harm to the frame. 

If you notice your bike seat won’t go any lower, you should check to confirm whether or not the seat post is stuck. You can take it to the store where they’ll get it fixed or replaced. 

#2. Chemical issue

Environmental conditions can also affect your bike seat, leaving it stuck in the seat tube.

These conditions may cause corrosion to certain metallic parts of your bike, like the seat post.

When corrosion affects your seat post, pushing it down becomes impossible, and thus, your bike seat won’t go any lower. You’ve probably stored up the bike too long and not lubricated it.

Also, if your bike seat won’t go lower, while you tried to lower the seat post, it had reached its limit and hence can not go any lower than that.

In such situations, you should cut the seat post off to a particular height that suits you.

Make sure before you cut the seat post that it has reached its limit in the seat tube so that when it’s necessary, you can raise it higher again.

How Do I Make My Bike Seat Lower?

To make your bike seat lower, you’d need a friend first to help out. Also, you’d need;

  • An Allen wrench
  • Level
  • Nail polish

Here is a step-by-step process you can follow to lower your bike seat. 

Step 1: Stand beside the bike and adjust the seat height by lowering it to just below your hip. Carefully lower the seat post to adjust the seat height. 

Step 2: Mount the bike and place your foot to spin one of the pedals into a sitting position.

Ask your friend to stand before the bike, holding the handlebars. Place your foot on the pedal and observe a slight bend in the knee of that leg.

Step 3: Alight the bike and adjust it downwards to the perfect height. Using an Allen wrench, loosen the bolt on the seat post clamp.

After losing the bolt, securely tighten up the clamp. Align the seat front with the stem to ensure it is straightforward.

Step 4: Remount the bike and re-test the new seat height. Put your feet on the pedal and spin backwards.

You should be able to complete a pedal stroke without your hips rocking. If your hips rock, the saddle is still too high. Readjust by loosening the bolt on the seat post clamp. 

Step 5: Place a level on the rear and front of the bike seat to ensure it’s perfectly level.

Step 6: Could you test it out? This test could help you confirm that your new seat height is perfect. 

Step 7: Apply the nail polish to the new height of the seat post just above the seat post clamp to mark your perfect seat height just in case you raise the seat in the future.

New Bike Seat Post Won’t go Lower?

If you get a new bike seat post, it should be able to go very low to a certain point. If its limit is too high for you, there’s an easy trick.

If you decide to cut it on your own, you should remember to put on a mask for protection.

Common Reasons why Bike Seat Post Won’t go Lower

A few reasons could be responsible if your bike seat post doesn’t go any lower.

#1. It has reached its limit:

Every bike seat post has a particular limit at which you can lower it into the seat tube.

Once it reaches the limit, you cannot lower it any further. This limit may be why you can’t seem to lower the seat post.

In such situations, you can reduce the seat post’s height, which would mean cutting off part of the seat post.

Or you may take it back to the bike store to get one that suits you more perfectly.

#2. Improper fixing of the seat post:

The seat post may get stuck if you do not fix it properly or if it is oversized and forced.

Forcing a seat post into the seat tube gets the seat post stuck due to the very tight space and makes it immovable.

That is why lowering the seat post seems impossible. It could even cause damage to your seat tube or frame.

It would help if you got it checked and had the right-sized seat post fixed. 

#3. Corrosion:

Your seat post is metallic and hence has tendencies to deteriorate in its metallic nature due to interactions with the environment.

Corrosion mostly affects old bikes that the owners have not used for a long time. If your seat post gets affected by corrosion, it becomes impossible to lowe it. 


If your bike seat doesn’t go any lower, possible explanations may be responsible, like corrosion or the seat post may be stuck.

Either way, you should have it checked and fixed to prevent further damage to your bike.

Also, riding your bike at the appropriate height is better to prevent damage to your backbone.
