hey i have recently purchased a unicycle from ebay, your bog standered
unicycle. 3 weeks later i road to college, and upd'ed loads of times
and couldn't see why, later i relised than my hub was not right. if
held the wheel and aplyed pressure to the pedel it would move. meaning
that i didnt have 100% controle of my wheel .therefor if i was riding
then stoped moving the pedals i would keep going,then fall.

is my hub f*cked or is it fixable.

I think in a public forum frequented by males and females of all ages
groups, backgrounds and cultures, br*ken or dam*aged, or irr*pairable
would be so much nicer as a thread title.:p

I can see three places there could be movement:

Hold the wheel steady. Can you wobble either of the cranks? If so,
then the cranks are loose. Easily rectified. 14 mm socket spanner.

If the cranks are tight, can you hold the unicycle frame still and
wobble the wheel? if so, then the bearing clamps may be loose. Easily
rectified: usually a 10mm or 11mm spanner.

If the bearing clamps are tight, and you can hold the unicycle still
and wobble the rim, then maybe the spokes are loose. Easily rectified
by a local bike shop.

There is a tiny chance that the hub is broken, but not with normal
riding and UPDs.

John Foss, the unicycling philosopher, goes right to the point.:)

This is unclear. If you hold your wheel your pedal will move by how
much? Is it a fraction of an inch or several revolutions? Small motion
under those conditions indicates a loose crank. Several revolutions
indicates a faulty hub. What type of hub is it? Is it splined or does
it have cotterless tapers?

Was the thread title you chose really necessary? I think "Is my hub
broken?" might be a better choice becauses it both addresses the
problem and avoids any insinuation of lewdness.

I'm offended by the title also but don't worry I won't go and burn your
embassy I have self control.:p

Anyways my brother has a cotter pin unicycle that the cotter pins come
loose quite often and gets quite a bit of play which sounds like what
you're describing.
Do you're cranks slide on to a square fitting or do they have a pin
that goes through them?... if they have the pin you need to tighten the
nut on the one side which tightens the pin. If they have the square
then just tighten the nut like mentioned above.

This sounds like the axle is slipping inside the hub. It sounds as if it
were pressed in and has become loose. If so, it is probably trash. If
it is pressed with a keyway and the key came out it can probably be
fixed. Do you have a photo of the thing? Maybe someone will recognize
it and can tell you how it's assembled. A photo of the unicycle and a
photo of the hub and cranks. If it is not a fancy unicycle you might be
able to get a new one for what it would cost you in time and money to
fix the old one. Photos are easy to post but should be resized to no
more than 640 pixels wide.

I think that's incorrect - at least if you're talking about what the
software allows. Rather, photos should fit inside a 800 x 800 pixels
box.

That's one more of us and one less of them.

Seriously, most of us just want this to stay a 'family friendly'
website where parents feel secure to let their kids freely browse
around for unicycling related info.
This place is a wonderfull tool for the growth of the unicycling
community and unicycling as a sport and I think it's worth dialing back
our language just a bit to make sure that it remains as widely
accessible as possible.

I'm not continuing the issue, I'm simply explaining -why- it is that I,
for one, took umbrage at the thread title.

Back to that hub.
'Here's a thread' (http://tinyurl.com/ae5zx) with some pictures of a
hub problem (and a dodgy thread title?).
I'm not sure if this will help you.
I would at this point suggest that you get it down to your LBS (local
B*ke Shop) and ask them if they can diagnose and fix the problem.
Unless you're a serious DIYer, the problem (if fixable) will probably
need professional attention.
If you can get the pics up easily, do so, there are some people on
these fora who really know their stuff and can probably help you
diagnose the problem. But if it's going to be a hassle getting the pics
up, save yourself the trouble and get it to a pro.

Welcome to the fora, let us know how it turns out.

if your unicycle hub is broken like it soonds as if it is, after only 3
weeks of normal riding, it sounds like it was faulty. Was it new or
used when you bought it from ebay? If new I would ask them to replace
it, alot of the people on ebay are actually stores so you have rights.

If it was really cheap and not new it might not be worth fixing, it
might be cheaper to get a new one since a new hub would be $20.

But I would complain to the guy who sold it to you, just watch your
language!

Good deal. This is just a different kind of "freewheel" on a unicycle.
Must have been an eBay store that you got it from. Too bad you have to
wait but glad you don't have to pay through the nose to get it fixed.
