  1. I've got my son a 16" Uni for his birthday. He's only had about 2 hrs
    practice and has gotten as many as 5 revolutions before falling. The
    problem seems to be that as he gets going,the motion gets real
    jerky,like he's stopping at the bottom of the stroke and can't get it
    back up. I put the seat from mine on it so I could try it and it feels
    kinda the same way,but I can still ride. For me it feels like the cranks
    are too short,of course my legs are longer than his. I taught myself to
    ride a long long time ago,and have never taught anyone else,so I'm kinda
    at a loss. He is 10,but has short legs. I had to cut almost 3 inches off
    of the seat post to fit his inseam. Here is a pic of him on it with his
    leg fully extended if anyone wants a look and give me some advice.
    Thanks for any help,
    Mike

  3. That was how I learned. I kept getting stuck at the bottom and then
    getting [censored] because it would be so simple if I could get past that
    position. Turns out I just had to practice more. Maybe it's the same
    with your kid. Get the whip and make 'em practice! 😉 He'll love you for
    it once he can ride.

    That's what I was thinking. Practice is not a problem so far. Lets
    see,he it got at 4:00pm,practiced till about 4:30,went to football
    practice,did homework,back outside at 9:15pm,practiced till 10:00pm,got
    up early this morning,got ready for school,took it to the bus stop,and
    practiced till the bus showed up. Pretty much the same secnario today.
    He's just about past the newness excitement stage and slowly working
    towards frustration,but no sign of giving up,which is something he
    almost never does anyway.But he still gets ear to ear when he gets a
    little further than the time before.

  5. a couple of thoughts

    first things first
    make sure u get the seatheight right
    to do that get him to put his HEEL on the pedal and help him sit in the
    seat
    when seated, his leg should be straight but not locked

    moving on
    from your description it sounds like a fairly traditional 'put your
    weight on the seat' issue and is quite natural in the uni-learning
    curve
    we're bi-pedal animals and when we feel unstable, we quite naturally
    transfer our weight to our feet in order to find stability
    on a unicycle (as on a horse) u need to learn to counter this
    instinctive reaction
    the leg muscles have to make minute adjustments to keep u in the balance
    envelope and they, quite simply, can't do that when they have to carry
    your body-weight (not while u're learning at least - in muni a lot of
    time is spent riding out the saddle)
    with too much weight on the pedal, that pedal will stop in the BDC
    (bottom dead-center) position and there is preciously little u can do
    from there
    except UPD
    u have to suggest to him that he focusses on keeping 70% of his weight
    on the seat and 15% on either foot
    suggest to him that he looks up and across the backyard instead of down
    on the ground in front of the wheel
    this will help with a more upright posture
    also suggest to him to focus on sitting as upright as possible
    even slightly exageratedly so
    from shoulders thru hips to axle should be a straight line, leaning
    slightly forward
    also suggest to him that he focusses on turning over the pedals in as
    smooth a circle as possible
    help him ride along a support for a couple of revolutions so he can get
    the feel for the smooth rotation of the pedals

    now, once he starts riding a lil' way futher and u notice that the uni
    is twisting from side to side with every pedal-stroke, he's simply
    sitting a lil' too upright and needs to lean forward perhaps a eight of
    an inch

    i hope some of this helps

  7. the way i started off learning since i got one for christmas was in my
    house going through hall ways with my hands on the walls and i did for a
    couple of days then when i got outside i used cutches for about fifteen
    minutes then threw those to the nside and just practived and that worked
    perfect for me so if u could find some place like a haallway outside ur
    house then that would be great otherwise u have to be alright with ur
    kid riding around ur house hey i didnt break anything

  8. If the seat hieght is correct, then try letting him ride on a slight
    downhill slope. The slope helped me keep momentum on the dead cycle
    while I was learning.
