SR Suntour SP12 NCX Suspension Seatpost with Cover (31.6mm x 350mm)

The design of the suspension causes the seat to deflect towards the rear which feels more natural than a straight up and down movement inherent in the lower priced suspension post. A new user should fine tune the adjusting bolt so the system is right at the point where it only requires a slight bump to cause seat movement with rider aboard but not so soft that the suspension moves when pedaling. I needed to adjust mine several times but I think Ive got it perfect now and I love it.

So great like having a new bike..

Takes the spine jarring out of my hardtail converted e-bike. After researching seat suspension systems this looked to be the best tech (but at a higher price).

Wanted to buy an electric bike but Rad Power Bikes did not ave this available, no problem, Amazon did. So I know have my EBike, couldnt be happier on both counts...

This made a world of difference in the ride!

Smooths out my Rad Runner Plus E-Bike and sets the seat farther back where it belongs. Im 57 and it fits all the way down while still able to put feet on ground. Takes the bite out of 70+ pound E-Bike!

Fairly easy to install, makes for a smooth ride!

Makes a big difference in ride quality over uneven pavement and trails. Excellent service in getting a missing part to me.

I have a bad lower back and my new eBike doesn’t have any suspension, front or rear. So I did the research and decided to go with the Suntour NCX. So happy I did. My ride is so much smoother. Bump and cracks that I would swerve around to avoid impact on my back I now roll straight over, and my back barely feels a thing. The spring absorbs pretty much all the impact. Easy to install with the correct shim for my specific seat post inner diameter. By far the best accessory I’ve added to my new eBike. Well worth the cost…it’s a godsend! Seriously, if you have a lower back issues and feel the jar of every bump in the road, but this seat post. You won’t be sorry. Best purchase of 2021 for me…other than the actual eBike itself.

I bought the suntour post and a touted seat to make my Rad ride happier. The seat was not helpful but the post made a big difference. The suspension smoothes out the rough spots and makes the ride more comfortable.
