Suspension seat posts are an ideal solution for ebikes where rear triangle space is critical for battery storage and the drawbacks (a bit more weight and a bit less efficient when pedaling) are negated by the electric motor. 

Luna is proud to offer authentic Thudbuster Seat posts at the lowest price anywhere to make our customers e-ride a little bit cozier. 

This is the ST (short travel version) which only gives you 1.3 instead of the 3 inches the LT gives, but for  some riders the 3 inches is too cushy.

Thudbusters have proven to be enough suspension for most ebike riders and is a very popular upgrade.

Full suspension mountain bike frames are not well suited for mounting ebike batteries. The ideal ebike conversion has always been a hard tail frame because then you have a full sized triangle to mount a battery pack.

A Thudbuster gives you 1.3 inches of suspension which is good enough for most ebikers.

Since most Ebikers are not riding really technical off road, a suspension seat post is usually adequate suspension instead of a rear suspension.

  1. Worth getting

    Posted by Andrew Young on Oct 9th 2017

    I paired this with the KHS 1000 4 season bike. Between this seat and the aired down tires its not bad for a suspension free bike. Don't get me wrong it's not even close to how a full suspension feels but it's a big improvement over without thethudbuster. I'm 250 lb fyi.

  2. Great seat post!

    I paid 150 dollars on Amazon for this post before Luna started selling it. This is a great post especially if you don't have the room for the larger LT model or you don't want a ride that is too squishy. Very good at smoothing out the vibrations of the road and soaks up and takes the edge off medium sized bumps as well. I would say this is more for people that ride roads, MUP's and smoother dirt trails.
