# Speed record

What is the very highest speed that anyone has ever gone on a uni? I’m not talking coker speed here, i mean real phenomenal speed attempts, probably done on specialy made unis. Any one got any idea?

in that Thunder Dragon video clip.it looks like KH is gliding at a realy high speed.although that whole clip looks a little speed up so i dont know if was quite as fast as it looked.

These two entries are what the web (read: Google) had to offer after about 2 minutes of searching:

Seems to me it’s something that could definitely be up for grabs. Obviously Harper would have to be in on it all (is a uni2.0 possible, or are there constraints in the sizes of the sun and planetary gears that keeps it at it’s current uni.5 size?).

I’m thinking a uni.5 (or better hub) with a custom-made rim (anyone know if it would be possible to build a Spinergy-style wheel for a uni? One with 8 “spokes” or so… preferrably made of carbon-fibre). Something of the titanium or carbon ilk for the frame. The wheel would have to be as large as possible, with very tiny cranks, so someone with as long legs as possible would be needed as the rider.

This could be cool (and expensive).

I dont think riding can match gliding. Yeah, High speed gliding is the way to go at it.

Im pretty sure that brett “bloodman” no clue on howto spell his last name has the rcord, with his high speed gliding.

My friend kyle are going after it though. Hes going hi speed gliding hardcore on a modified torker down a wicked steep hill, Im doing a follow cam in the buick. Ill let you guys know how it goes.

In relation to getting an epicyclic hub with a 2:1 ratio.

I looked into this a while ago. The ratio of a plantery gear system is definded as

## ((number of teeth on sun) + (number of teeth on ring))

``````               (number of teeth on ring)
``````

If you solve this so that the answer is 2 (i.e. the ratio is 2:1) then you find that (number of teeth on sun) = (number of teeth on ring) so there is no room for the plantery gears.

This means that a hub can approach a 2:1 ratio but never achieve it. The only way to gear this higher would be to put multiple gear systems within a single hub.

Thanks

Re: Speed record

None of that footage is sped up. He was going fast, but I don’t know how
fast. For sure not as fast as Brett Bymaster’s record of 25.5 mph. That was
gliding on a Miyata 24.

Re: Speed record

It might be possible to set this record by jumping off a high place onto
lots of pads. From 16’ high (exactly 1 second fall), the speed would be
21.8mph. If you could jump off something 20’ high, you’d get 24.4mph. Kris
may have gone this fast on a 15’ drop when you consider the forward momentum
part of the equation. 32’ into water might be possible and would give a
vertical speed of 30.8mph.

Maybe tow dragging would be a way to go faster than this.

Some 20 years ago I heard about Floyd Crandal achieving, for an instant, a speed
of 52 kilometers per hour on a big wheel. I am not sure about this and don’t know
if it has been verified.

Re: Re: Speed record

Didn’t someone do a parachute jump with a unicycle and attempt to land on the uni and ride away from the landing? If I recall, they were not successful in riding away. Don’t know how long of a freefall he had but I would bet he set the speed record during the freefall.

Re: Re: Speed record

I get the impression that this is in relation to his (failed) attempt at the 100 mile record in 1980. If so, he was using a wooden wagon wheel weighing 50 pounds or more. This was the main reason he was unable to keep up with Cathy Fox, who did win the record at that time.

52 km/h is an outrageous speed, and if it had been done I’m sure there would have been more attention/hubbub, articles about it, or at least some recorded information that would have made it self to the USA Newsletter by now. So I think it’s a rumor or exaggeration.

Jumping off a cliff does not count as “riding” a unicycle, even if you ride away from the landing. I give you credit for surviving, but not for the speed of a freefall. The same goes for riding on a train or plane, as a friend of mine has done.

If I were the one keeping track of records (which I may someday be), I would count gliding and self-powered speed records separately. Therefore, unofficially, I would guess that Brett Bymaster has the gliding speed record, at an unofficial speed of 25.5 mph.

For a proper ground speed record, if you really want to get serious about it, one should ride through a timed speed trap in opposite directions, to cancel out wind speed, and take the average time. This is how it’s been done for automotive land speed records for about 100 years, and it’s how I believe the IHPVA does it.

That’s the International Human Powered Vehicle Association. Once upon a time, in 1986 I believe, Floyd Beattie set a speed record for unicycles on a brand new 45" that had just been built for him. Because the cycle was so new, he hadn’t had time to get comfortable on it and was not as fast as he could have been. I think the cycle was assembled the night before or something. I don’t remember the details of his attempt, but the IHPVA requires a 200 meter speed trap in both directions. His average time came out to something like 22 or 23 mph. I think people have been recorded as going faster than this on Cokers.

Floyd also set an hour record, trying to beat one from the year 1888 or so, for which some old records exist. He wanted to break 14 miles, but missed it by a tiny bit. He was a purist and only would drink the water he started out with (not accepting any handed up to him). He got dehydrated, and had to stop with less than a minute remaining to be sick. I think there are Cokerheads out there today that could probably easily top this record as well.

RE: Speed record

How about power-gliding?? Gliding after a car or like it. Last summer I
did a speed record of 50 km/t, I guess I would convert to 31,25 mph.

Arne or Poul from Germany might have gone faster than that…

Re: RE: Speed record

The power gliding is amazing. I hope that I never get skilled enough at unicycling that I attempt to do power gliding – I would surely hurt myself.

Your links got word wrapped on the forum. I’ll repost the links so the forum people can easily click on them.

A year or so ago someone posted a link with pictures and descriptions of Arne power gliding. The site was in German but made for an entertaining read after a crude Babel Fish translation at AltaVista.com. Does someone have that link? I couldn’t find it using groups.google.com or the forum search at unicyclist.com.

Could someone who knows German ask in the German forum on unicyclist.com for the link and any additional background info on power gliding (like has Arne gone even faster now?)?

The higest speed reached while actually pedaling a unicycle that I know of is 47 kph (29.2 mph)

Christian Hoverath reached this speed trying to pass a biker on the European unicycle tour.

While this may sound like an unbelievably fast speed those who have seen Christian ride will understand how it is achievable. It equates to about 277 rpm

(The maximum I’ve reached is 227 rpm so I’ve a ways to go yet

Well, my understanding is that Christian Hoverath (who is a level 10 rider
and is young and extremely fast on any uni) rode nearly 30mph down a hill
in pursuit of a biker while on EUT. When others have reported seemingly
too-fast eah,speeds (there have been several reports of people riding
25+mph), I have always been a been skeptical, but I’m not too skeptical
about Christian – he’s amazing.

Yeah, like while I was riding home tonight!

Actually, my ride doesn’t allow a straight ride for an hour – more like
two nice 20-minute rides broken up by slower parts in the streets and on
the bridge. But I have maintained about 15mph for an hour during last
year’s Unithon on Long Beach Island, NJ. That’s pretty fast, but certainly
there are some who could do better (Christian, Roger Davies, and a bunch
more).

I wonder whether Christian could hit 40-45 mph on Harper’s big blue uni
(the 29" that rides like a 43.5"). I would pay to watch him try.

That is amazing indeed! What wheel size and crank length was he using?

Why not apply to Guinness?

I don´t think Arne is present in the german forum. I met him the day
before yesterday on the german unicycle hockey tournament. His

I think I will put a 28" wheel on my ‘uni.6’ (with a gear ratio of
1.57:1. Then it equals a 44" and has a very light rim. It seems that
we may ride a city marathon in Duesseldorf next year with unicycles. I
want to ride my uni.6 and Christian will ride his coker, I think.

You can attach the ring gear to the frame, drive the planet cage and
attach the sun gear to the wheel. Then only gear ratios more than 2
are possible.

With my design (i used gears from a shimano hub where the planets have
two diameters) i could drive a ring gear with the larger diameter of
the planets.

But I´m satisfied with 1.57*26"=41" :))
