A wheelchair therapeutic foam cushion works OK for me on the Silvio. Professionals have designed these foam cushions for hours of use with minimal pain. The seat cushion that comes with the Silvio is way too hard, painful at 50 miles, torture at 100.
I went to a local Medical Supply Store, a super-pharmacy for serious medical problems. I found one across the street from a hospital. The Internet, including Amazon, also has a selection of wheelchair foam seat cushions.
I bought a 2-inch thick wheelchair therapeutic foam cushion for about $40 US, which I cut to size to stuff into the Silvio seat bag. 3-inch think wheelchair therapeutic foam cushions are for sale too, but I am satisfied with 2-inch thick.
Result: Longest ride 170 miles with only small pressure-point discomfort. No problem.
Tips
- Easiest to cut the foam with a serrated knife, like a bread knife.
- If the cushion is contoured, select the thin part of the cushion intended for where your bottom should go. Do not get creative and select the thick bulge of the cushion for your bottom, or this will just create a painful pressure point. I found out so you don't have to.
- Outline the original Cruzbike seat pad, and then cut about a half-inch in from that, because new foam cushion is thicker than original and has to be narrower to fit in the bag:
