Pulling a trailer with your unicycle?

if you were to make a trailor i think that it should be mounted at the
axel. This way the trailor doestn't affect the seats forward backward
movement in comparison the the axel. and the connector rod should
pivot side to side and swivel so you can lean and twist the uni to
turn. School just got out today so i think i will design one in cadd
tommorrow.

That could work. Basically you'd have to add a second frame with it's
own bearing holders to your axel between the current frame and the
cranks. Once the two sides have joined together have a ball and socket
joint that connects to the trailers tongue.

This would add sorts of weird stresses, and completely change the
maneuverability of the unicycle, but it would function.

And I feel almost bad trying to help.:o Surely there must be a better
way.
That aside, I think you will want to do this on a 24. Attaching the
hitch to the crown of a 24 will reduce the strong reverse tug every
time the trailer wheel hits a bump. As the world UPD record is clearly
within your grasp possessing such a device, the lower stature and speed
will be welcome. The higher gearing of the 36 is unlikely to be missed,
you will need the pulling power.
Perhaps a better idea would be a rear fender, on a 36, no trailer,
that large bulky saddle bags could be fitted. Stuff these with light
stuff, and try to balance by hanging heavy stuff under the handle
bars.🙂

I think a trailer would work fine on a unicycle, insofar as carrying a
lot of weight works on a unicycle in any way. I've pulled a kayak into
and out of the water via a shoulder strap; the balance isn't really a
problem, you automatically compensate for it. It will definitely
affect handling, acceleration/deceleration, and idling (possibly making
the last completely infeasible).

I've ridden moderate distance (20 miles) with an awkwardly-loaded
40-pound backpack. It's really not fun.

here is a basic idea for a trailor that i drew up real qucik. i decided
that ataching to the seatpost would be better than to the axel if i
used a ball joint (and be easier to make)

hmm...there seems to be a problem with that design, though. when
unicycles turn, the frame twists, which means the frame must be able to
twist inside that mount to the frame, like a head tube on a bicycle.

well i think with my design you could still twist the unicycle you just
move the whole arm with you when you twist but what you could do is
either put the balljoint up top near the unicycles frame which could
make twisting easier or put a bearing or something like that where the
trailor connects. But i think haveing some sort of bearing system
would be hard to make to where the clamp doesn;t slid up and down but
can rotate. also another thought i had was to make the ball joint so
that it can't pivot upward or downwards and put the pivot point up by
the uni (if the balljoint was moved this would not aply) this would
lessen the posibility of the trailor bottoming out when you lean back
too far.

ok so i changed it a bit. now the ball joint can't go up or down just
side to side and swivil. and there is now a pivot point up by the
frame

How do you mount if you can't lean the seat back?

Surely once you lock everything out like that, what you've designed
there is not a unicycle with a trailer attached, it's a tricycle that
happens to be made out of a unicycle?

nothing is really locked in the uni can pivot forward and backward. it
can lean and it can twist

Just becasue there is a pivot point doesn't mean it can lean back. The
unicycle frame pivots around the axle, so just because there is a pivot
on the tongue doesn't mean the seat will be able to tilt back for
mounting.

Your design limits the forward and back tilting of the unicycle in a
way that would make balancing much more difficult.

The attached to the unicycle axle design made much more sense.

Sarah Miller had a trailer attached to her unicycle at a parade thing a
bunch of us did a few years ago. I don't remember exactly how it was
fitted, maybe she will come along and give some insight or you could
send her a PM, her unicyclist name is sarah.miller

Which is not to say a trailer on a uni makes more sense then on an
airplane.😕
The sort of 2 wheeled trailers considered so far are wrong for a
uni. This design is copied from the bike, wrongly assuming the bike's
mechanical fore- aft stability we lack.
For a uni trailer, I think the trailer must balance itself always, to
be practical.
Perhaps a light weight, larger, 4 wheeled redesign of a child's
wagon. Fitted with brakes on the wagon. A ring where the wagon handle
is could fit around the crown of the uni, allowing instant frictionless
turning of the uni. Remember how the front wheels of the wagon are
steered by the handle ?
I believe this design is ridable. Maybe for "Burning man", or touring
Bonneville.🙂
