Enjoy a More Comfortable E-Bike Ride with a Suspension Seatpost!

bodyfloat-isolation-seatpostAre you looking for a way to smooth out the road and enjoy a more comfortable ride on your electric bike?

If so, you may want to check out a suspension seatpost as a way to economically add a little bit of rear suspension to your bike.

A suspension seatpost replaces your existing seatpost and provides a little bit of cushion using either elastomer bumpers, a coil spring or in some cases, an airspring system.

I personally use a suspension seatpost on my electric cargo bike and it really smooths out the ride!

Here are some suspension seatposts that you may want to consider for your electric bike.  These are listed generally from higher to lower price.

Parallel-Linkage Suspension Seatpost Design

These are nice because they have stiction-free travel, unlike telescoping suspension posts, there is no initial stiction to overcome.  The suspension mechanism works in the direct path of the natural travel of the rear wheel.

The parallel linkage design also tends to have less side to side movement for the seat post.

BodyFloat Isolation Seatpost: The BodyFloat isolates the vibrations between the vehicle (your bike) and the motor (you) so that you can be more efficient with your pedaling and enjoy a more comfortable ride. It provides up to 1.5″ of almost perfectly vertical travel.

Cane Creek 3G Thudbuster Long Travel Suspension Seatpost

Cane Creek 3G Thudbuster Long Travel (this is the one I have used for years):  The Thudbuster LT is one of the more expensive suspension seatposts but it is higher quality and provides 3″ of travel!

Cane Creek Thudbuster Short Travel: The Thudbuster ST is very similar to the LT but it only provides 1.3″ of travel and it is a little less expensive when compared to the LT.

Tamer Pivot Plus XC:  This is also a parallel linkage post and it offers around 2.5″ of travel.

Telescoping Suspension Seatpost Design

Telescoping style suspension posts offer an economical option but they tend to have a little more side to side movement of the seat that can be a little weird!

But these can be a great option to keep the price down and smooth out the road a bit.

Tamer Weekender:  This post provides about 2″ of travel and uses a spring and elastomer system.

Avenir:  This seatpost provides 1.75″ of travel using a spring and elastomer.  It also comes with shims to fit various sizes of bikes.

IMPORTANT! Suspension Seatpost Sizing

You will need to determine the diameter and length of your current seatpost and order the same diameter and same length (or longer) suspension seatpost.

Most seatposts have the diameter noted on the seatpost but you may need to remove it from the bike to see it.  The length may also be noted but that may be something you will need to measure on your own.  (1 inch = 25.4 millimeters)

In some cases you may not be able to order the same diameter size suspension seatpost, so you will need to order a shim that will fit your seat-tube (exterior part of the shim) and the suspension post size (interior part of the shim).

Here is a link where you can find seatpost shims.

If you don’t feel like you have the skills or tools to install the seatpost your local bike shop can help you find the best seatpost for your needs and install it for you.

Enjoy a Comfortable Ride! 

I hope this gave you some ideas on how to make your e-bike that much more comfortable.

Have a great next ride!

    HI, you also should see the Airwing “air” 320/360 seatpost , only compressed air spring, I got one on a road bike since one year months, (Cybien sport),
    and after a hundred miles necessary to run in the roll bearing, you got a confortable seat, you can fit to your weight,

      Hi Clint,

      I have briefly ridden on the ST version of the Cane Creek Thudbuster and I think you are right, 1.5″ for a street only e-bike is fine. The 3″ travel is nice for on and off road terrain, or a super plush ride 🙂

    I have the Tamer Pivot plus on a RMartin { E-Maxi MIPower } MTB style E-Bike with a Brooks leather saddle & love the combination It took me a while to get used to the seat giving way also to adjust it so it’s just right takes a few minutes but it helps alot saving my lower back. I’m 50 years old & clock 6000 miles a year on my bike. One tip on this Tamer Pivot plus post is people complain they can be a little noisy & you have to grease them as per the instructions Dont be afraid to slather it with a lot of grease it oozs out the top slightly first few miles of riding but once you wipe it clean it stops oozing & no noise for months. Wll made post I feel I got a lot for the money I think I paid 130 bucks on Amazom last year it’s holding up well I’m 195 lbs.
