What crank length do you recommend for 20" wheel, freestyle

I’m buying a Myata 20" freestyle. What crank length do freestylers like to use?

I’m using 5.5" on my Monty 20" and 5" on my Miyata 24". Happy with that

The 5.5 (140mm) are nice for trials, but they scrape on the ground if I lean too
far on a turn. Would 4" be too short? It seems tiny. I’m thinking 4.5" might be
nice, but according to the Drummond’s web site, they only come in 4" or 5" from
Myata. Are there any advantages to custom cranks over the Miyata cranks?

Overheard at my house, “Daddy, don’t you think you hae enough unicycles?”

well, Joe personally i use 3 inch cranks on my 20" wheel…now i know this is
short but it seems good to me and i can also muni(somewhat) with them…i
don’t know though, i may just be me; all though it may be that for
trials/freestyle if i need to hop it doesnt take to much space to get a good
pedal position… well i probably haven been too much help i hope that i have
helped some…

Best of luck, Chance

3" cranks!?!

Is this for real? Are there 3" cranks? This seems like a typo. I can’t even
recall having seen 3" cranks (unless maybe on a 12" or 16" uni). I have to say,
it sure would help get some speed on those 20" unis – when I ride my Schwinn ,
it feels like I’m pedaling in place. But I still can’t imagine that 3" is a good
idea…esp. for muni! - David

The Unicon X Male Freestyle Champion, Kazuhiro Shimoyama, rode with tiny cranks,
although I thought they were 94 mm which would be a little more than 3
1/2". They could very well have been 3". The Japanese style relies heavily on
spins, which I am told, are made easier with the tiny cranks. The Japanese
freestyle riders, especially the Toyoda Unicycle Club group freestyle, was the
most amazing thing I saw at Unicon X. It was a real eye opener as to what is
possible on unicycles.

I believe you can get even shorter ones, I’ve seen two inch on an unmimited
raceing uni , and once saw 1 inch but they were not attached to the cycle in
question, more to get round a legal technicality.

I have 4 inch on my 20 for hockey, five on my racing wheel , and 6s on the muni
and coker. I tryed 5s on the coker but didn’t like the hills.

It’s not a typo. Ono at UX used them for the marathon and I tried to ride his
24" uni. VERY fast but very hard to get going, stop and turn. Though it is very
fast, he couldn’t beat me in an informal 100 race against my Coker (at the UX
marathon site). But I think that for long distances he might actually have won.

Re: 3" cranks!?!

Based on my experience riding a Coker with 4" (102mm) cranks, I would bet that
the person trying out 3" cranks is not actually having fun if they are installed
and he’s trying to mount or stop or turn or slow down. :slight_smile:

Apart from the loose use of the word “exactly” I doubt whether the ratio between
wheel diameter and crank length would be the sole factor determining speed (as
Roger implies). Think of a 10" wheel with 1" cranks!

But 4.5" would be 114.3 mm, not 110.

If your assumption is that the human foot can reach a certain velocity
irrespective of the rotational speed, then your mathematical reasoning is
correct. But apart from the difficulty of maintaining balance, I don’t buy the
idea that shortening the cranks by a factor of two makes you a factor of two
faster. This reasoning might hold a bit better for extraordinarily long cranks
(like 8" versus 4" cranks on a Coker) but not for ever shorter cranks.

Re: 3" cranks!?!

There was a group of about 10 Japanese at UX that had these short cranks on. I
actually thought that they were 2.5" (63.5mm), but I did not measure them, 3"
makes more sense. It also equates exactly in ratio to having 110 cranks on the
Coker. I thought it was a fair match in the end, but the Coker with it’s extra
mass I think has the advantage with approximately a minute faster time - can
only give it approximately because the Chinese officials didn’t understand that
the unlimited race included 24" with short cranks and Cokers! I sold a pair of
3" cranks recently to a Cokerhead to put on his Coker, I haven’t heard the
results yet but I bet he is having fun.

OK… I did it in inches and that way it does look pretty exact 12/3 = 4 and
18/4.5 = 4

Because a unicycle is a direct drive fixed wheel there is no other mathematical
reason other than the ratio of the crank to the diameter of the wheel that
affects the speed of a unicycle. There are other factors that effect the speed
of a unicycle but the overwhelming reason is this ratio. I produced a
spreadsheet where I worked out the ratio for a series of different wheels and
cranks, showed the forced at the pedals and the movement of the foot. I did post
a text version to the newsgroup about 2 years ago and I of course can not find
my copy at the moment!

Re: 3" cranks!?!

Let’s not forget biomechanics. The human body is probably more suited to turning
4.5" cranks at 150rpm than it is at turning 3" cranks at 225rpm. That’s why the
Coker still wins, even the the “ratio” is the same.
