Review: Worked on my Sunny Health indoor bike and I love it! - 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.
Review: well done great item - 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.

## Features

- COMPATIBLE FITDESK MODELS - Specifically designed for FitDesk Bike Desk 2.0 and 3.0 models from 2013 and newer. Verify your bike’s model and year for compatibility, as this saddle extender does not work with older versions.
- UNIVERSAL SADDLE ADAPTER - Allows for the installation of any standard bike saddle with rails, offering flexibility in your choice of seat. Note that the standard saddle clamp is not included, so you will need to use your existing clamp.
- SOLID STEEL CONSTRUCTION - Constructed from high-quality solid steel for unmatched durability and strength. The precision welds and robust design ensure the saddle extender remains stable and reliable, even during intense workouts.
- ADJUSTABLE HEIGHT EXTENSION - Features an adjustable post that can extend the saddle height by 3.5 inches, accommodating taller users for a comfortable ride. The post can also be cut down for a lower saddle position, making it versatile for different user heights.
- RUST-RESISTANT POWDER COAT - Coated with a durable black powder finish that resists rust and abrasion. This coating helps maintain the extender’s appearance and performance over time, ensuring it looks good and functions well through daily use.

## Questions & Answers

**Q: Pole for seat for taller person**
A: No, it is a seat adapter that you can use for your own seat to work with the FitDesk Bike Desks.

**Q: is this compatible with the marcy NS-652?**
A: Yes, the FitDesk Universal Saddle Extender adapter will fit the Marcy NS-652 foldable exercise bike.  However, you will sit about 3" higher with a new bike seat attached.  Because the supplied seat clamp with this kit has a post stop that prevents the seat from being lowered farther on the bike post.  You will therefore have to lower the Marcy square white seat post two holes.  If you are currently using one of the two lowest positions your feet will not touch the pedals.

You could buy a different seat clamp that doesn’t have the post stop and lower your new seat an additional 1’ to 1 1/2" and thus have to lower your sq. white seat post only one position instead of two.

See my review below with a photo of the adapter attached to a Marcy NS-652.

**Q: Can you flip this and use the round part as the post that goes into your bike the take the 3 whole part and bolt it to your bike seat.?**
A: Yes

**Q: Does the "fitdesk universal saddle adapter" work with the "fitdesk semi-recumbent pedal desk" (the old fitdesk); i bought it from amazon in 2012.**
A: It worked for me but I bought my pedal desk in 2015

### ⭐⭐⭐⭐ Fits the Flexispot V9U
*by M***T on May 27, 2024*

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.
