Coker questions

Based on a 36" wheel with 125mm cranks, it's 23" from the top of the
wheel to the bottom pedal. Add a good 6" to get to your seat at lowest
extension, 29". Probably a little more than that to be safe, but
remember inseam measurement doesn't go to the floor, just to the bottom
of your pants so your actual leg length may be longer.

Hopefully someone will jump in here with a more exact number that's
known to work. Basically though, you don't have to be tall to fit a
Coker.

Next time, please put the actual question in the subject line, not the
fact that you're about to ask a question.

Rather than working with an inseam measurement, a better measurement is
the distance from the pedal in the lowest position to the top of the
saddle.

Adjust one of your current unicycles to have a Coker style seat height.
That seat height will be higher than for muni or trials and possibly a
little higher than many people use for freestyle. You want your legs
to have only a slight bend.

Adjust one of your unicycles like that and then measure the distance
from the pedal in the lowest position to the top of the saddle. That
will give you a better number to compare with various Coker
configurations and crank lengths.

Still not a perfect way to determine if you'll fit a Coker. There's
other variables to consider like which Coker frame, which saddle (a gel
saddle will have a lower profile than a KH Fusion), and whether you use
a rail adapter or not. It's not so easy to figure out especially if
you are just barely tall enough where half an inch either way will make
a difference.

My inseam is 71cm (aprox 28" I think). I am just too short for the stock
coker (but Roger from UDC has a 'short person's coker frame that he
made for me). I rode my short person's coker with 140mm cranks.

I a also just about too short for the new Nimbus 36er, but again Roger
was able to make some adjustments and I ride my Nimbus 36er with 125mm
cranks.

'I shortened both Radial 360 and Nimbus frames '
(http://www.unicyclist.com/forums/showthread.php?t=56041) to
accommodate my ~28 inch inseam. On my Nimbus I cut down the seat tube
to where measuring from the bottom of the seat lowest position to the
center of axle can be as short as 21.5 inches.

You have a nimbus and c coker?! Wow! Why'd you go with the Nimbus and
is it laverndar too?

I have a 30" inseam and I ride a stock coker with the seat almost all
the way down. there is an inch of seat post visible. THis makes sense
with Cathy's post, so seems like Foss's estimate of about 29" is right
on.

36ers rule!

I'm the same size as Podzol - 30" inseam. The seat (on my Radial 360)
was almost all the way down with 150mm cranks, but with 125s I can
raise 1.5 or 2 inches up. Either way, it makes a short person like me
feel quite tall.😄

My son was 4'11" when he started Cokering. But he couldn't comfortably
fit with 140mm so used 125mm cranks. With 140s somewhere around 5'0" or
5'1" or so is probably about it (assuming normal leg length).
