You've Got to Try It.

This thing is fantastic. I did not know what to expect - if I was going to be constantly bouncing up and down or feel like I was riding on a pogo stick. Neither happened. This device softens hard expansion joints in the asphalt and moves with your natural up and down motion.

Almost makes the Ocelot Pro a "soft tail" bike

Purchased and installed SR Suntour SP12 NCX Suspension Travel seat post on my Ocelot Pro. It makes riding dirt trails and rough roads enjoyable since you can stay seated and not be bouncing up and down on the seat. With a regular seat post I would be bumped three inches off the seat when going over a curb, but with this the post takes up the impact and didn't get bumped off the seat. Smaller rocks and bumps are not even noticeable. Highly recommend this to anyone that rides on rough roads.

This seat post is very well made and will definitely smooth my ride out.


This made a huge difference in my bike riding. Nice and smooth over the bumps. Your butt will thank you!

Total Comfort

I have a Jaguarundi.... I got this seatpost with the Ebike... It is wonderful... I have a back issue and short of having a bike with full suspension this seatpost along with the front suspension and the Fat Tires truly smooth out the ride on ANY surface. I highly recommend it. And the cost is on a par with and often lower than what I found from various on-line sources and area shops so its a great deal. It does add about 4" of height so it may not work for someone less than 5'3" or 5'4" or so... Thanks Magicycle for offering some excellent accessories!
