Just a quick dissenting opinion here:
I had the driver and passenger BeadRiders, and actually ended up selling them to Deb (before she had her new seat).
I wanted to like them, really. Reminded me of the ones I had in my 1971 Plymouth Duster.
However,
1. In New England, it just never really got all that hot for all that long to warrant them, plus
2. The lovely bride kept feeling like she was "rolling" off the seat on turns. I didn't feel that so much, but when she "rolled" she dragged me along off with her! :yikes:
Spyder riding is exciting enough (with our current steering and accelerating concerns) that we didn't need any added "fly by the seat of your pants" effect.
Like many things here, if there is any way to try before you buy, do it.
(BTW, We have the comfort seat now and
use the AirHawk on occassion.)
