This parallelogram seatpost suspension

could it be any good for unicycles? The suspension doesn't work linear
with the seatpost, instead it moves the saddle slightly backwards.
Allegedly the SR Suntour parallelogram suspension system doesn't
decrease the distance between saddle and pedals.

Looks like a more compact version of the Thudbuster post available at
Unicycle.com. I don't think the angular movement is a plus for a
unicycle, but it still works (moving the frame forward a bit as it
compresses).

I had a Thudbuster and it was like a rigid seat post. I was in contact
with designer and he said it relied on pivoting around the front axle of
a bike. A uni doesn't pivot, it just goes up and down.

It looked good though but did not allow much room for seat adjustment.
Consequently it has been replaced and gone to my old Pashley which is
made up of "great things" that I don't think are that great. This also
includes the nice looking, but super flexible Black Widow cranks.

Thanks for that insight, I was considering getting one.

A better idea for suspension is to make the Pantour hub work on a
unicycle. Just don't ask me how.

That Pantour hub looks really cool! For a front wheel. I think the
design concept precludes running a drivetrain through it. That would
probably require some sort of different approach...

They do a rear bike hub, so it's supposedly possible to transmit drive.
I don't see how brakes would work (rim or disc) with a moving hub like
this either. Looks like it would be impossible to keep the rim/disc in
the caliper. Weird.
