I was fortunate to be able to purchase a Cirrus Cycles BodyFloat suspension seatpost directly from the makers. I have been riding with it on my Kona Minute cargo bike for about 4 months now. Prior to the BodyFloat my lower back would get sore after every ride through town. Now I rarely notice any discomfort, so I am very pleased with its performance.
Currently the BodyFloat is made in relatively small quantities by local machinists and assemblers, so the price is necessarily high ($395 USD). There are future plans to have it manufactured overseas to bring the cost down. Naturally the BodyFloat will be compared with the Thudbuster. I expect there will be online shootouts in the near future - should be interesting!
Charlie Heggem, the sales and marketing person, is big into e-bikes (rides a Stromer) and is promoting the BodyFloat to the e-biking community starting with Vancouver BC and Seattle WA area e-bike dealers. I would certainly recommend it to any e-biker who experiences riding discomfort and does not want to go the full suspension and/or fat tire route.
