They have those geared unicycles. the 20 inchers that go as fast as 36 inchers, but almost as light as 20 inchers. So you could get the speed of a 36 incher (30 mph or so at fastest) and take it off jumps, you could do amazing tricks like backflips and stuff with that much speed and power, it could be the future of unicycling one day.
what are your guys thoughts on this?
any other idea’s
this is one of those stupid threads, that “somehow” has a good reason to exist.
Sounds cool maybe one day. I am convinced though that somebody like Fabian (anybody with a high jump) could backflip I mean they get up close to 4ft…
It’s been discussed before. Kind of expensive, not many people will be willing to pay thousands of dollars for a geared hub and then take it off a 15 set. Hub failure on landing will really suck and repeated double digit sets will practically guarantee that.
edit: IMHO backflips (body and uni together) don’t look that cool when I imagine it.
I think he mew that we just need to make them stronger.
30mph…o…k…
maybe down a massive hill with a geared freewheeling hub ?!?!?!
Ok…since when has anybody gone 30 mph on a 36er??
If you gear a unicycle up too much, it becomes too hard to ride to be enjoyable. Right now 1.5:1 seems like the comfortable number for Schlumpf. I’ve tried a unicycle with a 3:1 gear ratio once. I could ride it but would never have attempted to ride it fast, let alone over a jump or even any decent sized bumps. It had a 20" wheel.
was it internal gearing or a penguin?
Foss’s was a giraffe with different size sprockets on the bottom bracket and hub.
yea, I don’t think many people would take a penguin (what a geared-up low giraffe is called) off a ramp, or go for a speed record.
Penguin? That was a brand of unicycles, which included a short giraffe. I’ve never heard it used as a name for a geared-up giraffe. When Tom Miller used to make them he called them Travellers.
1) Perhaps.
2) Well me and Madison have cracked the 35km/h barrier. 
So what’s that in mp/h??? 
Florian Schlumpf has one. Which means his 20" is only geared up about the same as a 29" gear, but still…it probably means you could get some real speed up before launching various moves.
35 km/h = 21.7479917 mph
Isn’t google great?
T.
Thanks for that tom.
Or even basic arithmetic and general knowledge! What did we do before Google? What if there’s a power cut?
One mile = 1.609 km.
1.6 is near enough for most unicycle-related purposes. 1600 metres is a “metric mile”. That’s interesting because 16 is a binary number, so it’s easy to work out half, quarter and eighth miles in metric!
A “sun and planet” set of gears has a maximum ratio possible. I think it’s around 1.6:1, give or take. More than that and you’d need an even more complex hub gear.
The Sturmey Archer 3 speed - the robust and popular 3 speed bicycle hub was “Plus a third or minus a quarter”. That is, the top gear was the middle gear x 1.33; the bottom gear was the middle gear x 0.75.
So gearing a 20 up to 36 would require something far more complex, and fragile, than has been made yet.
You’re doing well on an actual Coker to exceed 20 mph (32 kph). I never logged more than 16 mph on mine, although that was on 150mm cranks.
If you want to treat it so much like a bicycle, why not, er, buy a bicycle? To me, the beauty of the unicycle is the elegant simplicity of the machine.
Significant figures are also impressive.
This is about right for a simple planetary system. The planet gears are infinitesmally small for a hub with a gear ratio of 1:2. I always figured a 1:1.8 ratio was attainable but even then the planets must be very tiny. The next most simple step is to use complex planets and a slightly larger ring gear. The smaller gear is driven by the sun and the larger one drives the ring gear.
It would be cool to get enough speed to hit jumps, but first the geared unis need to be more affordable. On unicyle.com they’re about $2,000.
They have to be more affordable to get more speed?
Oops. That should read compound. The post must have self-editted; I couldn’t have made that mistake.
Hmmm… For myself, I don’t want to see unicycling get into that kind of super-fast geared stuff. If you want to do dirtjumps, get a bmx.
Copying what the bikes do takes the originality out of unicycling. Right now, we have are own style. We keep developing our style but we keep it our own.
Also, even if you start doing jumps and shit on a Shlumph, bikes are still going to pwn you especially seeing as how you’re doing their style.
And shouldn’t this be in RSU?
