I bought this for my wife’s Aventon Level2.
We ride gravel National Forest Roads and rail trails.
Being short, she couldn’t fit a suspension seat post on her bike.
This was an economical and practical solution! She loves it ‼️ ‘Nuff Said!.
Tested on a paved trail. Only 4 stars till we see how it holds up on gravel.

The original Brompton C Line nipple tube can be used, and I rode for 70 km without wearing cycling shorts.
The only discomfort was from sitting on the saddle for a long time, with no other discomfort or pain.
I highly recommend it to everyone!
The old 4130 frames really smoothed out all the city road noise and bumps.
This innovation restores the comfort long gone in the modern aluminum framed bike supply +.
The old saddle spring I had compromised fit and failed in fatigue as expected.
Thankfully this was at my door in 2 days and makes a sweet ride out of my Specialized Roll.
Went out and hit manhole covers 50mm proud of the road with a sharp edge.
I avoid them when possible but this test gave my lower back zero issues.
Don’t hesitate pick one based on your ride position and weight and do not look back.
All the way home I hit the biggest expansion joints and cracks I could find and nothing…
Yes I like it!
Better design and fatigue tested. -Update 40 miles in I am very happy with the extra comfort delivered.
I will now stop testing and intentionally hitting the craters when possible but remain confident when traffic or other issues demand I ride through it!
Best $$ spend on my bike adventures yet.
Easy to install, easy to adjust.

I used to feel a lot of pain from bumps while riding my Giant Laxxx E+, but after switching to the Air Seat, it finally feels much more comfortable.

Last week, I went on a bicycle ride with my friend and noticed something new on
his bicycle that allows him to ride comfortably, even on rough and uneven roads.
The new product on his bike seems to have a significant impact, which greatly impressed me.

After using the Air Seat, I now understand why so many people recommend it.
Even on bumpy roads, you can hardly feel the bumps.
It’s incredibly comfortable, almost like magic!
Especially during long rides, you won’t experience buttocks pain – it’s super comfortable.
Everyone should give it a try; you won’t regret having an Air Seat. LOL
This new product offers both fun and comfort.
The moment you sit on the bike, it feels incredibly comfortable.

I just completed a 26-hour bike ride, and it was an endurance battle.
Fortunately, I had the Air Seat to protect my buttocks, for which I am truly grateful.
I rediscovered the bike again. Never thought cycling could be so comfortable.
This is the best suspension seatpost. Never buy analogues.
Competitive suspension seatpost are kinekt, red shift and cane creek!
I used only Cane Creek Thudbuster ST G4 (elastomer suspension seatpost).
I think Air Seat Full-Floating Saddle Suspension System is the best of suspension seatposts named above 
It was a great experience, and the ride was very comfortable.
