Are there any records of faired unicycles ever been built? In this
dreary weather I wouldn't mind riding something like this:

It's a fairing. it's to drop air resistance.

I doubt unicyclists can really go fast enough to warrant having one.
There are some bikers who do over 100 mph on faired bikes, but unis
really are limited as to speed. there's not going to be enough air
resistance to make the weight of the fairing worth carrying.

I'm not buying it. I can imagine some funny UPD's - to watch, not to
experience. Mounting and dismounting may be more cumbersome. Unicyclists
hardly go fast enough to have substantial benefit of a fairing. A
unicycle rides like ~~~~ so you would be slinging your banana through
the air which might actually -increase- air resistance. The extra weight
wouldn't be nice for belancing. Finally, a unicycle doesn't offer ample
opportunity to attach a fairing - but that is a technical issue that I
imagine can be solved.

Some of these issues might be solved by attaching the fairing to the
rider as opposed to to the unicycle.

I'm partial to the 'bumbershoot'

Great! This rendered my biggest laugh on this forum yet.

I understand if no one buys my faired uni, I wouldn't buy it myself.
After all, as UniBrier points out, there already exist such things as
unibrellas.

81 mph sounds like the record for *non-paced* cycling. I think speeds up
to 150+ have been managed with motorpacing. Mile-a-minute Murphy did a
one-minute mile about 100 years ago (paced). Surely bikes have gone a
lot faster since then?

Why use a fairing? I can think of three major reasons:
1. Improved speed
2. To look cool
3. Possibly to keep the rain off

1. Improving speed only works if you're going pretty fast in the first
place. Before messing around with fairings, a geared recumbent unicycle
design should be worked out. Got to get the frontal area down first,
before a fairing is going to help at all.

2. Yup, there's always looking cool. Only if you're fully enclosed,
you'd better have a lot of help starting and stopping! Not to mention
riding with any kind of wind. More about this below.

3. The purpose of a fairing, per-se, is not to protect you from the
weather. A weather-proof unicycle sounds pretty ridiculous. You can use
an umbrella to keep the rain off, but you still need something major to
keep the backs of your legs from getting soaked and dirty because of all
the water you're picking up and "wobbling" all over yourself. So I'd
recommend a rain suit and goggles.

Fairings make bike handling unwieldly. That's on a bike. Take away one
of the wheels, and a little bit of wind will keep you from being able to
ride in the direction of your choosing. Even a large wheel unicycle is
susceptable to wind. I remember once riding across a giant parking lot
at Jones Beach, Long Island, with Ken Fuchs. We were on 40" and 45"
wheels, trying to cross this parking lot with a very strong headwind,
hitting us at kind of a 45 degree angle. We literally had to tack, like
sailboats, to avoid flailing our arms all over the place!

Also true, and plenty crazy, but not as awesome of a record, IMHO.

For bikes wind resistance becomes an important factor even at moderate
speed. When going faster it will offer far greater resistance than
rolling resistance.

But as you imply, the upright position of the rider makes the fairing
quite useless for this purpose.

Perhaps in a downhill race with unis using coaster hubs ...

Think of a fairing that looks like the tail of an air plane. The rider
is housed in the upright part and the wing with its flaps could be used
to balance the unicycle, rather than the pedals. Alowing the rider of a
geared uni to really crank with there legs and balance by ajusting the
pressure of the air passing over the wing.

I agree. I hit about 40 on hills going home from school on a good day,
and the thing that stops me is wind resistance and a crappy bike. Then
again I'm in jeans and a t-shirt, so it's not like I have the most aero
clothing.

And when do you expect there to be a DH uni race on coaster hubs? I'm
thinking a time scale of 5 years to NEVER.

Ha, I wanted to post the picture I once saw (and thought I had saved
but I can't find it) of a blimp with an undercarriage consisting of a
single wheel and ask "Is this what you mean?"

The T-shirt tomblackwood linked to is NOT the one I mean.

Thanks all for trashing the idea about a faired unicycle. I have learnt
that the fairing would not increase speed, it would make my banana sling
and hence cause frequent UPDs. The fairing would not even make a decent
rain cover!

So unless you fill the whole thing with tobacco and smoke it, the only
meaningful way to use it is to plaster it with stickers. We all know
that many companys would sponsor unicyclists if only the machines
offered more space for advertising.
