  1. I recently got a 2nd hand unicycle at a flea market its pretty old and
    theres alot of problems with it. the problem i'm most concerened about
    is right pedal is complety bent out of wack. First of all im wondering
    if this will affect my riding second of all, how do i fix it. its so
    old that pedals dont come off so i cant take of the pedal axel thingee.
    if you know how to fix it your help is aprreciated

  2. it will probably throw off your balance. Personally i wouldnt trust it
    at all, I'd just take it off and buy a some good pedals for maybe like
    $20. I like BMX pedals with the grip screws in them, but the problem
    with those is that if u ever get them lodged in your shin it hurts alot.
    It all depends on what u feel confortable riding.

  3. The right pedal has a right-hand thread. That's anticlockwise to
    unscrew.

    The left pedal has a left-hand thread. That's clockwise to unscrew.

    You need a long handled 15 mm spanner. A god one, not one of those
    cheap pressed-steel bicycle multi-spanners. Maybe your local bike shop
    can help, if you can't manage it yourself.

    If the pedal axle is bent, there is no cure, and you need to remove the
    pedals and replace them. You will not enjoy riding a uni with a bent
    pedal axle.

    Perfectly adequate beginner's pedals can be bought for a few
    pounds/dollars. About the price of a pizza.

    Better pedals would make the uni easier to ride.

    If it is impossible to remove the pedals, then you will have to replace
    the cranks and pedals. All the parts are readily available from
    www.unicycle.com

    So, do you ride with a club?

    No, but I carry a heavy spanner.

  4. I bought some nice grey pedal and put one of them on my freestyle uni a
    bit cross threaded. I don't know how this happened but the pedal is now
    completely knackered. The threads were almost smooth. Unfortunately the
    bit it threads into on the crank doesn't look too good either.
    🙁

    I put the old pedals back on and the thread part of the pedal seem to be
    made of a stronger metal, I think it may have re-threaded the crank
    (does that make sense?). I think it may have been this pedal that
    damaged the crank in the first place, before I put the second pedals on
    because I had a bit of a problem getting it off.

    I hope I haven't broken the crank.

    PS sorry, this doesn't help you in the slightest, does it.

  5. Hmmmmmm.

    It seems unlikely that you managed to strip the thread on both the pedal
    AND the crank. That would take some effort, and would qualify you as a
    fully fledged engineer, even if you don't own a hammer and both sizes of
    screwdriver.

    One possibility is that the hard steel thread on the pedal was clogged
    with softer metal stripped from the threaded hole in the crank. If so,
    the pedal may clean up.

    It is pretty likely that the old pedal, with hard clean threads did
    manage to cut/clean a thread in the crank. It may survive, but it won't
    be as good as new.

  6. Thx all but the one i had was just a solide pedal frame you cant take
    them off, anyway i ended up shelling out 120$ but i figure it was worth
    it its much easier to ride and it has Fine pedals.

    Just experienced a similar problem with my son's uni. Suddenly and
    without warning his right pedal fell off. The tread in the crank is
    totally stripped and the the pedal now just slipps in and out of the
    hole. I assumed he'd been riding it a little loose, and as the pedal is
    steel and the crank alloy that the movement had over time stripped the
    thread. However he claims there was no looseness prior to the incident
    at all. On closer inspection it looks like the part of the pedal that
    sits against the crank has ground its way into the crank itself, so it
    seems like, in the same way that pedals can unscrew if they are ridden
    backwards a lot, so this one has continued to screw itself in until it
    finally stripped the thread.

    SO, did I tighten the pedal too much originally?

    New crank about to be fitted - I don't want to b*gger this one up!

    I think this is what happened to me. I have put different pedals on now.
    But I had to buy new cranks.

  9. What often happens is the seat gets turned around and then the pedals
    are on the wrong sides and then the pedals unscrew as you ride and it
    ends up ruining the threads in the cranks. Make sure your right and
    left pedals are on their proper sides.
