Beta testing of planetary geared unicycle

Beta testing of planetary geared unicycle

Post by harpe » Mon, 25 Feb 2002 04:05:06


David Stone recently proposed a process for beta testing the geared
unicycle. He thinks he was kidding but it is actually a very good idea
for a couple of reasons. At UNICON and the NAUCC conventions this
ummer, all people will have an opportunity to ride this unicycle (which
I have taken to calling uni.5 but am always open to suggestions) for
hort periods of time which will be fun but not enough to seriously
evaluate it. Also, having it in a venue like that greatly hinders the
testers' abilities to modify the unicycle to their own preferences (tire
width, tread, crank length, pedal type, etc). If I actually shipped it
around the country (limited to the continental US although there are
many Coker riders in the UK and Canada whose input would be valuable),
erious riders could spend some time with it and evaluate it more
thoroughly.

My goal was to simulate a stock Coker with a 36" wheel and 6" cranks. My
interest is in input from Cokerheads, particularly serious power riders
like Chris LeFay and distance riders like David Stone. I am not looking
for approval. I am looking for the honest opinions of knowledgeable and
experienced people who would comprise a market for this type of
unicycle. If you think it rides like an arthritic hippopotamus, that
tells me something. If it breaks, that tells me something (I have
another one anyway). If the gear backlash is too annoying or
distracting, that tells me something. If you would never consider buying
a unicycle set up this way, that tells me something. If you think it is
a screaming, lightweight, road speed monster that you can't live
without, that tells me something too.

I have ridden it about 5 miles while tweaking it and I plan to put my
Miyata air seat conversion on it and log another ten miles or so and
remeasure the backlash for the third time. Then I would remove the seat,
build a wooden, reusable crate and start it on its journey. UPS will
hip a wooden crate for $5 extra handling. Approximate shipping cost
from Seattle to Miami is $41. Each leg of the journey should be
ubstantially less expensive than this.

RULES FOR PARTICIPATION:

1.) There should be at least one experienced Coker rider at each stop.
Anyone else there may also ride it...friends, club members, but no
bears.

2.)An approximate log of the mileage at each stop should be kept.
Approximate means within a factor of two. If it is used 50 miles at one
location, 25 miles and 100 miles are both accurate guesses of the
mileage. Anyone interested in donating a used cycle computer?

3.) Only aluminum cranks may be used. The axle is unhardened steel and
will gall if steel cranks are installed. Any pedals, seats, or tires may
be tried. Please be careful removing or installing components. Always
hip it to the next stop with the 6" cranks installed. I will provide a
Torker seat on a 300mm post that I have no use for if I have one
response from someone who cannot provide their own seat and seatpost.

4.) You must pay the shipping costs to the next stop.

5.) The uni.5 should probably remain resident at each stop for no more
than a week, particularly in warm climes where it might become too
comfortable and take to wearing swimming suits and muscle shirts. An
exception might be made for the New York club and the Minneapolis club
where there are several riders.

6.) You should be willing to give comments and discuss your impressions
with the other riders in an open forum in which I would prefer not to
participate except to read them. I want to know what you think. I
already like the uni.5 because I am connected to it in a unique way. You
cannot insult me or my work by providing valuable information.

Those interested please e-mail me at:


and I will try to set up some kind of schedule. If there are too many
responses, please do not be offended if I omit you from the schedule.
Thanks for your help.

I'll ponney up my Cat Eye OS- it will keep ride data for several years
and produce daily/weekly/yearly tables.   I'll pick it back up at the

For those that are currious: I pay Harper for statements like this.  
For $39.95, you get 3 vaugly possible compliments and one outrageouse
assertion a month, plus an autographed picture of The Man demonstrating
his favorit level 11 positions.

I'm not privey to Dr. Stones araingement, but I susspect it costs a bit
more (the truth usualy does!)...

I'm not making a killing off of this angle. All of his checks bounce

You're doing great work, Greg, and it's great to hear how willing you are
to share.  Thanks to David for making the initial suggestion!

So, if you're making a list, I'd love to give the thing a try.  I don't
ride a coker nearly as much as David, or have a club in my town, but I have
ridden a few unicycles, and cokered about 400 miles last summer.

I'm in Rochester, NY until classes stop in the end of May, after which,
I'll either remain in upstate NY, or be in CT, Germany, or somewhere
completely different.

Incidently, there will be a juggling convention at RIT April 12-14th
(www.rit.edu/~jugwww), and I'm sure some unicyclists will be in
attendance.  Also, since NYC is only a day's ride away from me, perhaps
this would be a good time to swap the cycle with someone from David's
club.  I'm sure there are some jugglers there who would be willing to make
the trip so they can see Jason Garfield perform!

For those who don't know, Jeff Lutkus is a VERY proficient unicyclist
who has posted instructional videos on mounting a Coker as well as other
unicycling and juggling topics. Ridden a few unicycles...indeed.

Jeff, I plan on attending the RIT convention in April. I just got back
from a short trip to New Paltz with my girlfriend, and met some other
really cool Jugglers there. The school there is cool too. If I go there,
it would be great if I could begin some kind of organized club. Anyway,
what I am trying to say is that as long as my car is in working order, I
dont think that it would be a problem bringing it up. By the way, about
how long is the drive from NYC to Rochester?

Greg,

This sounds very cool! (and generous).
Maybe I could travel to one of the stops where the testing is to occur.

I don't know a lot of other riders here in Oklahoma.  I'm planning to attend
at Seattle, but I'm not sure how much could be obtained from such a brief
test.

If one of these hubs were mounted on a Coker,  I would consider a record
attempting distance ride.  (Maybe Guinness wouldn't care if it was "geared"
or not).

Also,  I think that speed bumps would be the hardest thing to deal with on
a 24" wheel at "Coker" speeds.

Glad to hear it.  (An aside since it was brought up -- the RIT convention
is a juggling convention -- there will be some unicycling activities, but
since unicycles are not allowed on the main gym floor, unicycling takes on
a very minor role... but, if you enjoy juggling, or would like to learn how
to juggle, by all means, come join us!)

I've never driven from Rochester to NYC, but I think I've heard it's
somewhere around 7 hours.  

So, Greg, I don't know how your plans are going for the route the unicycle
will make, but the ideal situation for me would be: unicycle arrives in
Rochester a week prior to the 13th of April (enough time for me to spend
the weekend playing on it, and take it to various juggling clubs during the
week), that way I can be very cool already being able to ride the unicycle
when the convention starts up.  Then, I'll pass it along to David, and save
some UPS charges ;)

(Ok, I don't have to get it before NYC, that's just the little kid in me
who wants that new toy, and wants it now!)

And Greg, back to the high praise you gave me earlier in the thread,
thanks.  If you say I'm a good rider, I'll take the compliment, but I've
got to say this -- from what I saw at last year's NUC, there are a ton of
waaaay better riders out there.  I just happen to be active on the
newsgroup (mainly because it's the best place to go when I have questions
about learning a new trick).  Maybe some day, I'll get around to organizing
my video clips into something useful ;)

Hmm, I wonder what it's like to glide that 24" coker.  I'll bet that would
be a lot of fun.  This also raises a good point -- is there an official
name for the thing?  Planetary geared unicycle is something of a mouthful.

You're a student...big words should be rolling off of your tounge all of
the time.

I have taken to calling it uni.5 (as in 1.5, the number of wheel revs
per crank rev). David Stone has recommended the 150 (as in 150% wheel
rev per crank rev) which also has appeal.

I doin't recommend using 150 or 1.5 for a simple reason. In lexicography,
we cally it "homophonic clash resulting form polysemy" -- something to
make your tongue roll. What this means that "150" and 1.5 already
have another meaning in the unicyling comain (hence "clash"). It refers
to the 1.5-wheeler (half a wheel on top of a full wheel) that I built and
rode in several Unicons. John Foss dubbed  it the "150". I've called
the 1.5 wheeler.

Good luck with your geared unicycle. A Mr. Tsukahara form Nagoya built
one many yeas ago, I think with a ration of 2.0, and it was "fun" but scary to
ride it.

Greg,

Planetary Geared Unicycle ..... or perhaps Planetary Unicycle - Geared.
So, you could call it the "PUG" or PugCycle.

You could come up with a whole logo of one of those pug dogs riding it,
with his eyes bugging out 'cause he is startled by the sudden speed.

:)

Wouldn't it just be like any 24"? Only the crankset is rotating slower
when you glide but you wouldn't notice until perhaps you want to catch
up with the pedals again.

Jack-

I was calling it the uni.5. I used the number 1.5 to outline the
reasoning. Uni, Latin prefix meaning one, followed by the decimal point
indicating the beginning of the fractional part, followed by the numeral
five indicating 5/10 or one half.
