    TRIWONDER Suspension Bike Seat
  

*by S***R on Reviewed in the United States on July 12, 2024*

The TRIWONDER Suspension Bike Seat works great. It was simple to remove my old seat post and install the TRIWONDER. It does a great job absorbing the bumps as you ride. It can be adjusted to any weight rider up to 400 pounds but I did not adjust it at all. It even comes with the allen wrench. I installed mine on an ebike (Electric Bike)) but it would have worked just as well on any bike.Pros:1. Works great. Very satisfied.2. Simple to install in a few minutes.3. Adjustable to any weight up to 400 pounds.4. Fits perfectly.5. Lightweight but strong aluminum will never rust.6. Good quality7. I recommend it and would buy it again.Cons:NoneNotes:1. Make sure you order the right diameter and length.2. You will need a crescent or socket wrench to remove your seat saddle clamps and re-attach.3. Some of the reviews are for completely different products made by TRIWONDER.4. This review is for the TRIWONDER Suspension Bike Seat.

    Great seat post shim for the money!
  

*by R***E on Reviewed in the United States on June 22, 2024*

I needed a seat post shim to make up the difference between my ebike's factory seat post and the suspension seat post I bought for it. This is a high quality shim, made of machined aluminum, and it fit my ebike perfectly!! Highly recommended!!
