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.
