2 wheeler kangeroo

Unicycles and Equipment
1

I was playing around with my kangeroo uni on the weekend and one of the
guys in the club suggested converting the 2 wheeler I’m babysitting to
a kangeroo.

Has anyone ridden a 2 wheeled kangeroo uni? Gilby?

Also who out there has mastered a 1 and a half wheeled uni? They are
mentioned in Jack Wiley’s book on how to build unicycles and artistic
bicycles. I imagine it to be about the most difficult unicycle you
could ride.

What an idea!! I used to extremely active in multi-sheelers but that
idea never occurred to me. I am sure it can be ridden but it probably
will be tough.

That would be me. I also built and rode a half-wheeler and zero-wheeler
(the “zero-cycle”). I wonder if anyone has scanned pictures of this, as I
am often asked to explain…

My “dream” has been to build a “-1-wheel unicycle” (yes, MINUS one), but I
still can’t figure out how to do that,

Nope, I have never ridden one, but i’ll have to try it sometime. I would think it’s pretty hard to do since you have to overcome the extra friction when bringing the pedal around back to the top of the wheel while pedalling. The friction makes it hard to do one footed as well.

<!doctype html public “-//w3c//dtd html 4.0 transitional//en”> <html> I
remember a TV commercial many, many years ago from Gulf Oil company where
people would drive around in invisible cars on the seats of their
pants. I imagine riding a -1 wheel unicycle would be something like
that. Or perhaps the dancing baby riding a unicycle at <A HREF=“htt-

A> is riding a -1 wheel.

Ok, Peter…what’s a kangaroo unicycle? This is a new one to us!

I have done that. It’s not that hard ti ride.

FYI, many years ago we had some kangaroo races at the nationals in Japan.

A kangaroo unicycle is what all Australian unicyclists ride. It makes it
quite a challenge to play unihockey.

Actually, it’s (just!) a unicycle with both cranks pointing in the same
direction, so you only have control over the pedals for half a revolution.
You can also try putting the cranks on at 90 degree displacements (or even
use different length cranks on the two sides). I believe it may be a good
way to learn how to ride one-footed.

Eek, sounds like riding one foot bacawards on a giraffe. Doable, but lots
of chances of your feet just coming off the pedals…

I have the pictures, but it’s way down on my life’s priorities list with
the other aspects of updating my Web site. Other stuff like being a
husband and uncle, being president of USA and IUF, and a little actual
riding always seem to get in the way! :slight_smile:

I’ll take a picture when you do, and publish only the negative.

To me, the most difficult unicycle type is still the B.C. Wheel. Jack
Halpern’s 1.5 wheeler (known in 1982 as the “150”) was actually not a big
step above riding a regular two wheeler. All you needed was a little
momentum to push you past the “dead spot” in the pedal stroke, and a brief
pause on the “control” side. I picked it up in only a few minutes, even
though I was never an expert two wheeler rider.

All you need is a few kilos of the right antimatter… watch out for
normal matter though.

Sadly the only antimatter yet produced was a couple of anti-hydrogen atoms
(I think) which lasted about 20 nanoseconds.

You’d have to ride it -really- quickly.

When you do have a little time, I would very much appreciate a gif or jpeg
of the 1.5, 0.5 and 0 wheelers. These are unsusal enough and many people
will show an interest of we post them.

That’s right. It’s not that hard, esp. if yo uride two-wheelers (which I
do). I lost parts of the 150, otherwise I wold have brought it to UX…

negitive one wheel? maybe if you carry two wheels that you don’t use for propulsion they could count as anti-wheels and ballance out the one that you are really using. preaty lame i know but without space-time bending (breaking?) equipment I can’t think of any other way to do it. Even then I am not sure how to that would work (anyone have a degree in theoretical astrophysics?)
