I was at a bike shop the other day and I saw a seat post with
suspension. Has anyone ever had a suspensioned Uni? Or is it not a
good Idea?

As I recall, you have to buy them to match your weight - so that the
preload is correct for you. Otherwise it would be too stiff or too soft.
Use one on a uni? It would probably work. I often wondered about
building a uni with a mountian-bike fork (the kind with shocks).
Is that what a "muni" is?

Somebody please build one of these, spend however much it costs, guinea-pig
it and tell us how it works out, okay? Thanks.
In the States there seems to be a common fork on some of the Cannondale
mountain bikes that has a single shock at the top of the fork crown. If
using a mountain bike suspension fork (instead of one made specifically for
seat posts), make sure it's adjustable so you can raise the stiffness. The
bicycle's front fork is not made to support the entire weight of the rider,
and so a regular one would probably bottom out just by sitting on it.

The way I see it, a suspended uni would do the same thing a suspended
bike does--allow you to ride farther/faster with less fatigue.
Now, if I could just figure out how to make the hub ...
