The BioFloat seatpost is designed to let the seat move with the rider's pelvis
For a great many people, one of the most unpleasant aspects of cycling is feeling every little bump in the road, transmitted through the seat and into their butt. Various companies have responded by offering suspension seatposts, such as the BodyFloat and the CF3 Pro Carbon. While those and others soak up some vibrations by flexing up and down, the prototype BioFloat seatpost takes things further – it functions as a shock absorber, but it also allows the seat to move around sort of like the head on a bobblehead doll, moving with the rider’s pelvis instead of pressing into it.
