I have just finished building my first eccentric wheel.
Looks nice.
What is the offset and crank length?
Whoa, that’s insane. Can you ride it?
It’s a 20" wheel with a 50mm offset. The cranks on it are 145mm.
I can ride it with the cranks fitted as pictured (9 O’clock and 3 O’clock with offset peak at 12 O’clock)
It is not too difficult to do short distances but I find it very tiring and run out of steam after only 50m or so.
I am off out to try with the cranks both pointing at the longest spoke now, if you never hear from me again it could be a bad sign…
Lovely, I’ve been thinking about making a wheel like that for a while, just curious, did you calculate the spokelength? if so, how?
Or did you make the spokes as you built the wheel?
I used the spoke calculator from here:
It worked fine although some of the spokes that enter the rim at an oblique angle could maybe do with an extra mm length to compensate for the kink in the spoke & the nipple not pulling down flat because of the angle.
I managed to free mount it & ride 14 pedal strokes so I am happy. 
It is not too difficult and it is a great feeling to be bobbing up and down like a well known marsupial.
looks very cool, Mike!
Hope you take it to a convention or two! 
Cant wait to have a go!
You done any Trials on her yet?
Cheers,
Joe,
(Ps. Took my Trials out today, did some big drops… wheel is great! Thanks! 
)
Cute. Any chance for a video clip?

Looks nice. When I was a relative beginner (level 1) I once spent
about an hour on an eccentric 24". Riding it was not so difficult. But
when I went back to my regular 24", initially I couldn’t ride it at
all due to my biased motor memory (or something). It felt so weird!

If the crank is moving then it really sounds as if it’s loose. - onewheeldave trying to pinpoint the cause of a clicking crank
I posted some video clips of EWU’s with 1 and 2 inch offsets for this thread.
It would be cool to see a vid of this one too.
whoah! that’s crazy. very cool…however, may i ask what the point of it is?
Well, Zach, what’s the point of riding a giraffe? I rest my case.
a giraffe is a tall unicycle, this looks like it’s just a hard-to-ride unicycle.
case? hahaha (malicious laughter), you never had a case.
Wow! Great work Mike. Did you have any problems lacing it?

Joe: Trials on it!#*? I think I will leave that one to you…
Duaner: I am afraid my video potential is limited to a quality that makes it difficult to see that there is even a unicycle there…
Klaas: My son had that experience too, he literally fell off his normal uni…
Zach: I think maybe I missed the point years ago, no reason to start looking for it now… I would be keen to find an even harder to ride unicycle now, any suggestions?
Andrew: I laced it in the same way as normal but some of the spokes need to be bent into quite a tight curve to get them in. I took care not to kink them & they straightened out ok. If anyone has a better way of lacing an eccentric wheel I would love to hear please. The other tricky bit is guessing how much tension to put on each spoke, in my case I just did what felt about right from experience of building normal wheels…
well, since people have already made the unicycle taller, shorter, bigger, smaller, offset the center of the wheel, taken out everything but the wheel, made the wheel a “free wheel”, taken the frame off that free wheeled uni…and…umm, i don’t know could we challenge ourselves anymore?
…how about making the eccentric wheel into an ultimate eccentric wheel? or an impossible eccentric wheel?
Very cool, Mike!
That wouldnt work… would it?
I would have thought that when the pegs get to the lowst position, there would not be enough force to push them back up… and when they are on the way down, they would come down fast!
Thats what I think… anyone?!
Joe,
Which is why you’d have to only ride it on off-road downhill tracks, of course. Like, duh…
