  1. I am finally starting to ride the giraffe I bought years ago, but was
    never brave enough to get up on. It has ceased to be just an ornament.
    A 5 foot giraffe grows in height as you climb up on it. To a spectator
    it may only be 5 foot. To me, perched on top of it, it has to be
    double figure height. So it still scares the hell out of me, but...

    It is a DM twin chain, a heavy, solid beast. I hope to be able,
    eventually, to do simple riding forwards, maybe backwards, idle and
    juggle three clubs on it. Freemounting is not on the immediate wish
    list. Tricks also are not essential. So a question for the experienced
    giraffe riders here. What would you consider to be an ideal crank
    length for comfort when doing this sort of riding, on a 5 foot DM?
    Any tips on seat type? I don't want to keep the T bar seat if I can
    find something more friendly.

    And what is the safest way to get off a DM giraffe? Other than the
    parachute?

    Thanks Nao

    The dress in which I unicycled was not THAT short, but in retrospect, I
    think that maybe the blue one would have been more appropriate to the
    terrain. Nao April 2007.

  2. 125-140mm cranks should do the job...it all boils down to personal
    preference, riding style and types of riding you'll be doing.

    As for dismounting: Exit to the rear of your aircraft...hold onto the
    front of the seat and step off/drop to the back allowing the unicycle
    to move forward. This way you can dismount safely when you know the
    unicycle isn't going to shoot out and hit someone or something.

    I foresee a problem here. My DM giraffe's seatpost and seat doesn't have
    the standard four-bolt pattern, but a different three-bolt triangle
    pattern, with one bolt at the front and two bolts at the back. Apart
    from other DM giraffes I've never seen or heard of this bolt pattern
    used anywhere else.

    So the only way to change the seat (to a non DM seat) would be to
    change the seatpost first. I can't remember if the post diameter is
    25.0mm, 25.4mm or 25.8mm (the pains of metric conversion).

    As Dustin says, make sure there's plenty of space _in_front_of_you_,
    grab the handle on the front of the seat, take your feet off the pedals
    and drop straight down, making sure the wheel scoots _forwards_.

    If you can jump off a 4ft wall safely, you can dismount a giraffe
    safely.

    I wish I could mount mine. Four years after I've bought my six footer
    I've still never attempted it at all! 'Cos I'm a wimp and I'm scared of
    heights.

  4. I agree with what everyone else says. Dismounting on the back side is so
    much nicer than on the front side. I don't feel hardly any impact
    compared to dismounting on the front side of the uni. When you are
    learning and/or getting used to riding on the giraffe (it's a bit
    different feel cause of the chain drive and the height) you'll probably
    dismount/upd off the front side at first. This will hurt a little bit
    because your not used to it but as you get more experienced you will
    learn how to absorb the impact.

    P. S. If you ever decide to try learning rolling giraffe mounts, check
    out the tutorial in my sig 🙂.

    Haha.

    You guys should give it a try. I've only ridden a giraffe twice. I was
    able to freemount within about 10 tries.

  6. Once you start riding it regularly, you will eventually get tired of
    having to find a wall/steps/ladder to mount the thing.

    A handy 'cheat' in the meantime is to mimic the freemount while holding
    onto something like a lamppost.
    That makes it much easier to get on, and especially when trying to
    mount while holding three clubs.

  7. If the giraffe scares you, remember to think of its height not in terms
    of where the top of your head is, but where your feet are. On a
    5-footer, that's less than 3' off the ground. No big deal at all.

    Essential skills:
    You really want to learn to idle and go at least a little bit backward
    on your giraffe. Without those skills there are many more ways to hurt
    yourself, others, or the giraffe itself if you get into a pinch.
    Consider those the basic skills of entry.

    Cranks:
    The ones on there should be fine. Short or long, unless you plan on
    taking it offroad or something, crank length isn't really relevant. The
    old Schwinns were made with 140mm or 5.5" (one piece) cranks.

    Seat:
    Find out your post diameter and then work from there. If it's an odd
    size, you might have to hire someone to either make you a post to fit
    your new seat, or just cut the top off the old one and weld on a seat
    plate for the appropriate seat. That's what I did with my DM ATU, where
    the original post is now topped with a gusseted Miyata mount.

    Dismount:
    What Dustin said. Always check for bumps or other obstacles before
    letting your wheel roll out. Never let you wheel roll out to the rear
    unless you're absolutely sure there's nothing there. If it hits a curb,
    for example, it could cause a back injury. You can also hold the pedals
    steady and come down in a arc. This arguably softens the blow because
    you start slower, though you then come down at an angle. When you get
    more comfortable up there, a good-looking dismount is to make a sudden
    stop while popping the seat out in front of you, then jumping straight
    down to land next to the unicycle, holding it up. That's my "show"
    dismount. 🙂
