Wouldn’t it be nice to have a unicycle seat that is still comfortable after 5
miles? I know from bicycling that a lot depends on putting in more time on the
seat and “getting used to it.” However, without handlebars to share the load, a
unicycle seat carries an extra burden.
Here is my latest effort: It is based on a Semcycle seat–the one with the
strong steel plate and the removable tough vinyl cover. I like the seat’s shape
and its strength relative to a Miyata seat, but I can’t do serious hills on my
Coker without a handle. So I took the front handle off of a scrap Miyata seat,
drilled holes in the Semcycle seat plate, and fastened the handle using longer
carriage bolts.
I removed the Semcycle’s firm foam padding and replaced it with a 12 inch 1.5
inch air tube, and put a piece of 2 inch soft foam on top of that. The soft foam
is the kind you would find in a cushion, and I cut it to shape.
When I put the seat together and pumped up the tire, the seat cover tried to
come off at the back, so I punched a series of holes in the seat cover and laced
it up with boot laces. Now it holds fine.
Comfort: Definitely better than the Miyata airseat it replaced. But still not
perfect. I also modified a Miyata airseat by adding the 2 inches of foam. I will
test it out soon.
Any other seat modifications working for you out there?

Depending on the seat and cover you are using, the cover trying to come off is a
possible indication of too much air pressure. The two air seats I made (now
stolen) both contained air pressures probably in the 20-30 range. If you put in
too much air it starts to feel like a regular foam seat.
I use the Semcycle seat w/12" tube. I normally pump up the tube to the point
where the seat cover starts coming off the back and then bleed off enough air
until the cover “fits”. I never checked the pressure though. It is more comfy
for long rides but I lose some control over my uni with this much air. I also
carry a spare seat tube after one time I rode 2.5 miles back with a flat seat

I was thinking that a handle could be attached via the seat post with the use of
a BMX ahead style stem. Then a person could design a “hand bar” that has a place
to mount a break lever or computer. Would it work? -Mary

Before I pump air in the inner tube, I wrap an ace bandage all around the tube
and seat. The ace bandage stretches with the tube, but still manages to
confine it.
