Got this to go w/ a new Bakcou eBike that is a hard-tail, to protect my back from the small, jarring bumps on the trail. These are expensive, yes, but the build quality and smooth action is top-notch. I bought a workhorse eBike, as I use it more for riding downtown and to run errands, including some cargo hauls. It does exactly what I was hoping, dampening the small, yet sharp, bumps from the trail, making it a joy to ride and not a painful prelude to the chiropractor.

After more than fifty years and over 250,000 miles on a bike, this is one of the top three transformative bicycle components I've ever tried. I installed it on my "adventure" e-bike, which has a bone-rattling all aluminum frame and weighs in at over 50lbs. Combine that with a slender individual who lacks natural padding, down there, and you get a situation that sounds like a Yahtzee game every time I hit a bump! I've experimented with several suspension posts over the years, but they all fell short for various reasons. Some were too stiff, providing no discernible benefit. Others were so soft that a significant portion of your pedaling effort was wasted flexing the seatpost spring rather than propelling you forward. And all didn't offer the required range of adjustment or granularity needed to properly fine-tune the suspension to my needs. But Redshift got it just right! You can adjust and fine tune the suspension to your particular performance and stiffness preferences over a large range. What I appreciate most is its smooth and precise action without feeling overly spongy or sloppy. It has never "bottoms out" or rebounds inappropriately after absorbing a large bump for me. There's no noticeable yo-yo effect when you're putting out maximum pedaling effort, and it effectively dampens post-bump rebounding. It's akin to driving a classic Citroen DS with Hydropneumatic suspension! Make sure to follow the installation instructions, especially regarding the seat's fore and aft position and the seat height, as they WILL be different from your usual settings. I intend to purchase four more of these for my other non e-bikes.

So far, I've got two of these installed on my e-bikes. They help make rides more enjoyable and less painful, whether long or short. The difference was night and day compared to the stock static seat posts. Compared to a SR Suntour NCX, it has no rattle and is easy to maintain pedal efficiency while still providing a maximum level of suspension. I weigh approximately 220 lbs and have the pre-load just about maxed out with the extra spring installed, so if you're heavier than that there may be better options for you. Highly recommended for a smooth ride on hard tail bikes!

Unbelievably great! I am almost 68...and riding my fabulous ebikes ( Freesky Alaska and Wild Cat are mine... . Wife has a Freesky Rocky) bikes are my daily exercise . For daily use my Alaska (big one...dual batteries) does laps around our 3 acres nightly, usuallyat over14 mph. I have extra lighting so I miss most of the ruts/potholes in the yard...but I always manage to find them. All 3 of our bikes have full...front and rear....suspension but a 6" hole 4" deep at 12mph plus still transmitts that jolt into your back even with a great older age gentleman wide seat. I added this yesterday..... Unbelievable! It definitely catches what the rear shock doesn't catch and it's fluid smooth! I can’t describe the difference. It is fully tunable...so as I loose weight, adjustmen is super easy! VERY SATISFIED!!! Because my ebikes are 30.9mm tubes, be sure to get the correct shim....I purchased a 27.5 to 30.9. Excellent fit! I also replaced my lever quick release with one that is more secure...that is tightened via a hex screw. I am about to purchase a 2nd one for my Wild Cat....and I'm sure once my wife tries it...it will be a third purchase. FYI...Because of the larger tube and beefed up locking ring, I am not using the provided "magnetic fender". Get this...your back is worth every penny! I'm an engineer...and a pilot...and appreciate well engineered things...this gets a 10 out of 5 star rating!! Oh....it's also a little shorter than others available out there..90mm from max insertion to seat rail. Most of the others average over 100mm.

I just received this and have only rode around 5 miles, so far. Like butter. Smooth and linear, unlike cheaper units that deliver a ratchet non-linear response. I tried a much cheaper unit around $120 and I had a STRONG instinct that it was a counterfeit. Plain super cheap box with no branding. On the manufacturer’s website they warn of the high risk of counterfeit. I believe the seller gets them from ali express or temu. I sent it back and ordered this. The Amazon Redshift is sold by Redshift. No ambiguity about the authenticity.
