FitDesk Universal Saddle Extender FDX 2.0 & 3.0 Adjustable Seat Post Riser | Fits Standard Saddle Sails, Adds 3.5 inches of Height, Solid Steel Build, Rust Resistant Finish, Adjustable Riding Position

Worked on my Sunny Health indoor bike. Bought my(just like new), indoor bike off my buddy for $75 bucks about a year ago. Had been collecting dust in the garage till I decided to re-kick start my cardio recently. The stock seat my bike came with was uncomfortable and not designed for Spin type exercises, which I like. Didn't want to splurge on an indoor Spin Bike just yet, so I decided to buy this adaptor which fit my Sunny Health Bike perfectly. Yes, flat and lock washers included too. No issues. Took 15 minutes. 1(2 works best) small crescent wrench(s)(to remove the old seat and to tighten bike seat collar), Hex Key/Allen wrench(don't recall the size I used. But a cheap set from the 99 cent store would work). Looks and feels sturdy. Did raise the seat level up a bit but was able to adjust to a lower setting on the seat post. Great price and easy to assemble. No regrets. Hope this helps.

This is a excellent part to convert your Exercycle seat to use a cycle seat and ad height and adjustability, strong part and easy to install well done.

This FitDesk Extender fit my SPEC Premiun Folding Bike!!!! The hole did match and I was able to change the seat to a smaller one. The adjustiblity is perfect, the comfort and size are balanced for stability; the thickness makes the seat well balanced for a secure ride that will not let the narrow saddle slide of or come loose from riding the bike for exercise up or down hill, ruggard or less tension.

This fits the Flexispot V9U very well. Keep in mind the plastic cover needs to be removed to access the bolts. Also, do throw away the split ring lock washers, they do not help. They're actually worse than nothing, using them will result in vibration loosening the bolts faster than normal. This is true in general, they are a bad design that doesn't seem to go away despite being proven to be ineffective. After installation I also just removed the plastic cover since it's no longer useful with the adapter. I just twisted it and it broke apart and I was able to peel it off.

I like the fact that I was able to cut this to make it look nice and a seat fit properly to my Life Fitness C3 upright. It is solid metal, but not hardened. I purchased a cheap electric cutting wheel from Harbor Friend and cut it in 5 minutes. This is well made and the fit is proper for a universal 3 hole mount.

Fits Schwann AD2 perfectly and holds a way more comfortable seat. However after a week of use the plate is bent and the weld holding the post on is cracked in half. At any time this weld could fail and cause serious injury. I’m 6’3” 220lbs, this should have a beefier weld and plate to be safe for the rider.

Based on measurements given by other posters, I decided to try this for my Schwinn AD2 Airdyne exercise bike. I'm happy to report that it works quite well. I had trouble getting the bolts into the nuts with both washers on so I eliminated the flat ones and used only the locking washers. The adapter is firmly attached but will probably need and occasional tightening. I wasn't able to push the seat all the way down the post. If I decide to keep the saddle I'm testing, then I will make a greater effort to push the seat down further. The seat had its own post connector which is identical in size to the one sent with this adapter. Figuring in shipping for each, this item came out less than 37% of the price of the other adapter.

Pictures make it seem like the height is adjustable but you have to find someone who cuts metal in order to get it cut and home depot/lowes all the common places you go for wood do NOT cut metal, at least not in my area. Called over 15 places before i found a small locally owned place who said they would cut it for me but they dont normally cut metal they dont personally sell.

I brought this to replace the saddle on my Roger Black Gold exercise bike. The Sadle on the bike is the worse and most uncomfortable saddle I’ve ever used. This adaptor fits the Three bolts in the bottom of the saddle and allows you to change to a saddle if you’re choice!

This is a long term review as we bought this May 2018 and have used it for a number of months. We have an old exercise bike that worked absolutely perfect but the old seat cracked and we needed to find a replacement. The manufacturer of our old exercise bike no longer exists and we've been unable to find a replacement so I decided to switch the old seat and bracket to something that is universal. After a few minutes of Amazon searching I came across this " Universal Saddle Adapter " so I decided to make the purchase and see if it would work out. Upon an easy install of this adapter I quickly put on our new seat, tightened things down and gave it a try. It worked absolutely perfect. It is made of heavy thick steel coated in a black paint and during our use of this it held up well with 30km - 60km rides per day. For a durable seat adapter this I'm sure will work well for you just as it had for us. Helpful, is how I hope you find my review

Alles bestens !

Me llegó muy rápido y ajusta perfecto a mi bicicleta estática en 5 minutos estaba instalado, el material se ve sólido y muy bien fabricado.

I use it for a regular bike seat on a Schwinn Airdyne2 exercise bike. It's perfect.
