"Ultimate" Unicycle

I was e-mailing with George Peck, and he liked this idea enough to suggest
someone build a proto. Here is the idea:

Build a crank-less uni where the frame attaches to the pedals. The frame
parts attached would have to rotate in the way train wheels do (where that
metal piece rotates around several wheels at once), and the parts would be
attached to a regular seat. The point is to build a planar unicycle, and
since it’s like a UW, I’d call it an ultimate unicycle.

By the way, I just got my UW a few days ago. I can’t ride it yet, but I
can hop on it with my hand on the top and also with no hands. I don’t use
a foot below a pedal (it’s not hard, tho), but I can also do it by keeping
my feet squoze around the middle of the wheel.

David,

Can you put up a sketch somewhere? The idea sounds interesting but I can
fully visualise what you mean. Normally a pedal connects to the axis via
the crank but there is no…

David,

Please post a picture of your concept for the Ultimate Squoze Cycle. :wink:

On subject: remember those pictures posted a short while back from that Chinese competition of that big hoop wheel? It looked like the sadle was supported by a fender that stradled the wheel on rollers. Seems like this aproach would have fewer moving parts, and allow for foot placement closer to the wheel- almost the opposite of that funky Russian Sun Wheel.

Christopher LeFay

Hmm, interesting indeed. I’d expect this moving frame might get in the
way of doing tricks. In spite of this, I’d like nothing more than to see
the result.

To add to randomness, after thinking about the train analogy (don’t ask
how my mind works), I started to think about a kangaroo unicycle. Would a
kangaroo with an off-center wheel be easier to ride than one with a
properly centered wheel?

What an interesting idea. I wonder if it is rideable – instinctively it
seems as if it would be very hard. What do the others think about calling
it an “ultimate unicycle”. I will add it to my slowly growing
multilingual unicycle dictionary. I should organize the data and post a
new edition one day…

I suspect it wold be harder. A kangaroo is easy enough to ride once you
build up a bit of momentum.

“HA!”… “I” got an email from George Peck too. So there! :wink:

Okay all he said was “Go away and leave me alone.” but still… ('nother
grin/wink)

David, I can’t quite get your design around my brain. All I can imagine is
peddling with your bum bones. Kinda like what I’ve seen women do as a butt
exercise across the floor. But hey… that could work! :slight_smile:

OK, it’s hard to convey in print, but the idea is this, (starting from the
seat and moving down):

Seat Beneath seat, two separate attachments for the two half-frames (one
on each side of the bottom of the seat) Two separate half-frames, one on
each side Each of these attaches to one of the pedals (between the pedals
and the wheel) Since the pedals move up and down, the frame-halves would
have to operate like the wheel-linker of a train so that the seat would
stay fixed. I guess the half-frames would be sorta L-shaped with a piece
that slides back and forth (like those train-wheel-holders)

I hope that’s helpful.

Another idea for an ultimate-unicycle-type effort would be an “Ultimate
di-cycle”.

  • 2 narrow solid wheels linked by a solid axle
  • left and right pedals screwed into their respective wheels
  • narrow 700c rims and 19mm tyres
  • a “1-pronged fork” with a bearing housing at the bottom
  • maybe some linear bearings to prevent the wheels rubbing
  • normal saddle

Kind of cheating? I thought we were talking about a UNIcycle.
Multiwheelers are still unicycles because only one wheel is in contact
with the ground. If the twowheel you describe turn separately, this is no
loner a unicycle…

Why would they turn separately? The effect would be a unicycle with a wide
hard tyre (60mm+ wide).

(Only one of the two tyres would be in contact with the ground when
turning or leaning.)

I mentioned 700c(622) 19mm tyres as these are the narrowest I know of. You
could use 25mm 26 inch (559) tyres for a 24" version.

Leo White

Mr. White,

Why must you insist on adding to the list to things I must do…?

I can SO readly imagine the handling problems of the beast- I just have to ride one!

Christopher LeFay

David,

I am interested to understand your contraption but I still don’t get
it. A wheel linker in a train has fixed length, so the seat would not stay
fixed but wobble up and down, or actually tumble
left-right-left-right. I ended up on the same thought as Christopher
Grove: you would ride it with your bum bones but the movement would be
pretty wild. (Probably much to Christopher’s liking depending on who
rides it…)

If you have no webspace to put a drawing up but yet could scan a sketch
and e-mail it to me, I’ll be happy to put it on my site and post the url
here. Please compress as a jpg, or probably better still: make a 2-bit tif
(only black/white) and zip it.

“To trigger/fool/saturate/overload Echelon, the following has been picked
automagically from a database:” “NSWG, DONCAF, BX”

Would this design also be something like pistons in a car engine? If you
could get the rigidity, you might be able to have two separate wheels,
with the supporting crank shafty bit running down the centre of the two
wheels. I haven’t sketched this out (even in my mind) but I suspect it
would be difficult to maintain strength. Also, if the wheel was only
attached to the crank shaft at one place, the wheel could follow a funky
elliptical orbit. Maybe I’ll try and sketch it out.

I’m still trying to figure out what such a unicycle would be for. If only
to be novel, that’s great. But I don’t see any advantage to a drive
system that sounds like it will weigh at least twice as much as an
ordinary one…

This sound’s more to Chris LeFay’s “sodomized by his unicycle” liking than
mine! But it could help out in the “doin’ it on a uni” thread. %)
