    I was messin' around in Excel, and came up with the following little
    tool that let's you easily calculate your speed and cadence, and allows
    you to predict your theoretical top speed on your uni. It's pretty
    self-explanatory. Check it out...

    22425

    I'll follow up this post with another with the file attached in Excel.
    To run it, you'll need to use Winzip to get it on your local drive and
    Excel to open it.

    If any of you Excel wizzes out there spot any errors in the
    calculations, please let me know...

    I hope someone else finds this interesting! 😉

    Paul

    There is a similar calculator at 'IronJungle'
    (http://www.ironjungle.com/) called 'UniCalc'
    (http://home.austin.rr.com/ironjungle/sw.html#UniCalc). You can check
    your numbers by running the same calculations through UniCalc.

    John:

    Thanks for remembering my calculator. I have had several people ask
    for the lockcode.

    It's free for all to enjoy. All I ask is that you place a pin on my
    Frappr map.

    Thanks again!

    You wouldn't happen to have the source for your application, would you?
    What language is it programmed in?

    Thanks.

    I worked too hard. I measured the rotation of my 36" and came up with
    the same 113" and divided into the # of inches in a mile giving me the
    # of rotations per mile. From there i did the same for all the
    unicycles I owned to see how far/fast I could go .... ie how much time
    I wanted to exercise and how much time I wanted to spend exercising. I
    am glad for the calculator I lost lost the paper I did the calculations
    on! Ha!

    When calculating cadence and such for a Coker you should note that a
    Coker wheel is not exactly 36 inches in diameter. The actual rolling
    diameter is closer to 34.8 inches based on the rollout.

    Check the 'Coker rollout measurements'
    (http://www.xs4all.nl/~klaasbil/coker_rollout.htm) by Klaas. Most
    rollouts are in the neighborhood of 2780 mm for the circumference. So
    adjust your input values accordingly.

    Yes, rollout is a factor of the specific tire you have. We have lots of
    reported measurements for Coker tires, but the Radial TA tire might be
    a different size.

    Also, just because your unicycle has a 24" rim, don't assume you're
    rolling out a 24" diameter distance with each rotation. The Miyatas we
    used to ride came out to about 23.3", and my Wilder with a Gazzalodi
    tire is almost 26". Consider tire size before starting your
    calculations.
