The Correct Seat Post Size

As previously stated, installing a cruiser saddle on a mountain bike requires a new seat post built for such a saddle. The seat post must fulfill certain requirements for the conversion to be successful.

In an ideal situation, the diameter of the replacement seat post will equal that of the original. Additionally, it is feasible to utilize a seat post with a smaller diameter and a shim.

Usually, MTB saddle posts have a diameter of 31.6mm. Check the markings on the seat post or its grip to determine the seat post size on your bicycle. You may determine the diameter of the seat post by using a caliper or a ruler if necessary.

Note: The seat post should have the same or greater height than the original. Otherwise, it may be tough to raise it sufficiently to make pedaling pleasant.

Proper Installation of the Seat Post

Once the proper seat post has been determined, it is time to attach the saddle. Slot it onto the seat post’s smaller diameter part to install the cruiser seat and tighten the clamp.

You may stop the seat post from rusting by applying a small oil coating to its body. It is especially crucial when the frame and seat post are manufactured from different materials. Check read this link for more details on lubricating a seat post.

Note: Observe the seat post’s minimum insertion length to avoid damage to the seat post and frame.

The Advantages of Installing a Cruiser Seat on a Mountain Bike

  • Comfortable Riding Position

When cycling in an upright posture, cruiser saddles provide more comfort. When the rider stands upright (back is perpendicular to the ground), weight is transferred toward the rear wheel. Additionally, the contact area between the rider and the saddle expands.

A broader, springier saddle is advantageous since it decreases the tension and vibrations transmitted to the rider’s body. Classic city bikes use cruiser-style saddles rather than competitive saddles.

Downsides of Installing a Cruiser Seat on a Mountain Bike


Cruiser saddles only provide comfort while the rider is upright. If the bicycle’s geometry is more aggressive, a broader saddle might be unpleasant since it generates a great deal of pedaling friction. Therefore, road racers use very small and hard saddles.

An MTB with a cruiser seat is more likely to be functional and comfortable if its geometry is adjusted to favor the rider. Consequently, cruiser seats are often fitted on vintage MTBs that have been transformed into commuter bicycles.


Cruiser seats are huge and employ a spring system to ease the ride. You will surely be disappointed if you put one on a current MTB. This combination gives upright comfort at the tradeoff of added weight.

  • The perfect replacement seat post would be an exact fit for the old one. Users may alternatively choose a thinner post and support it using a shim.
  • Some cruiser saddles include rails that clip into the seat post, allowing easy installation.
  • It is possible to mount a beach cruiser saddle onto a mountain bike, but doing so often necessitates purchasing a new seat post since most mountain bike saddles are not designed to fit into a regular MTB seat post.
  • Cruiser seats are typically used on bicycles with a more relaxed seating position. If you put that saddle on a racing bike, your thighs will constantly rub against it. Consequently, road racers’ saddles tend to be narrower.
  • Compared to racing saddles, beach cruiser seats are noticeably more cumbersome.

In a nutshell, you can install the seat from a beach cruiser on a mountain bike, but the ride quality will be less comfortable with a seat made specifically for a mountain bike. Stick with a beach cruiser seat to ensure the highest level of comfort possible in your seating arrangement.
