How do I change the seat on my NordicTrack bike?

It could not be easier to install a NordicTrack S15i and S22i indoor cycles seat replacement. All you need is a 6mm Allen key and a new seat.

What seat is best to use with NordicTrack S22i and S15i indoor bikes?

Although this depends on personal preference, riding position and budget, there are three main things you should consider when looking at the best NordicTrack bike seat for you.


Most bike seats come with either foam or gel padding. Some will also have a combination of the 2 giving the best of both worlds. It is generally agreed upon that gel padding is more suitable for longer rides or people who are not as used to sitting on a bike seat for long periods. NordicTrack S15i and S22i indoor cycles seat replacements should be waterproof so that regular sweating will not cause the padding to deteriorate too quickly and reduce how comfortable the seat is.


The ventilation on your new seat is crucial. Mainly because you will be using it indoors without any airflow to help keep you cool. Look out for an ergonomic design with a ridge down the middle and ideally a large cut-out, allowing everything to breathe a little easier.


There is no one size fits all when it comes to the most comfortable seats for NordicTrack S22i and S15i exercise bikes. It is down to personal preference, body shape and riding position. If you are new to indoor cycling or have a large build, then a wider seat will be best for you to start with. If you are not looking to sit too upright and are used to sitting on a bike seat for long periods, you will benefit more from a narrower bike seat. The quality of the bike seat and the padding material has a far more significant influence on comfort in the long run rather than width.

  1. It seems like I am constantly sliding off the nose of my bike seat. I changed to a different seat that is way better, but cannot get the nose up enough that I don’t keep sliding off and uncomfortable?
    Any suggestions?

    • Hi Cha Cha

      Did you try the Wittkop seat? It is the second second in our “nordictrack replacement seat article”. Use the mentioned seat and let me know if it works

  2. I used the Wittkop seat and i slide to the front also. Very uncomfortable and annoying!

    • Thanks for stopping by,

      I am sorry to hear that.

      Did you put the Nordictrack seat’s original seat clamp on the Wittkop or used the seat clamp that came with the Wittkop seat?
