Uni.5 43.5/29" two-speed shiftable unicycle

There is a gallery with eight views of the new, shiftable two speed uni.5. It’s on a Steve Howard custom 29er frame with cutouts for experimental shifting schemes. The rim is a Velocity dyad 700c and has a NanoRaptor 29" tire mounted on it. Steve’s frame accommodates an Interloc 27.2mm aluminum seatpost onto which is mounted one of his stainless steel, tiltable Miyata rail adapters.

I have 5.5" Lasco cranks mounted on it because I have to have aluminum cranks. I’d really like to get some blue anodized Kookas that are straight and the right length (5 or 5.5") but nothing like that is available that I know of. The pedals are blue Wellgos because, well, they’re blue.

The unicycle is shown with the hub locked in 1:1 or 29" mode. It will be shifted by removing a single stainless steel shoulder bolt and nylon spacer and installing them in the 1.5:1 or 43.5" mode position. I still have a stainless steel sleeve to press into the frame tonight for the 43.5" mode.

Steve and I hope to eventually incorporate a tool-free shifting scheme. Technically this is a very difficult problem to solve without substantially increasing the geartrain backlash.

Pretty, isn’t it? Pretty fast. Maybe I’ll work up the courage to ride it soon.

Oops, sorry. 50 years old…no memory.

The total weight is 15 pounds.

Harper,

Very shiny, very beautiful. That cycle is to die for! Nice stuff. Perhaps one day I can meet this beauty in person. That’d be nice. :slight_smile:

Take care,

Lewis

Greg,

My but you’ve lost weight as you’ve aged…50 years old, no memory, 15 pounds. How do you keep your figure?

B

ooooooohhhh. Its real purdy.

I really like the frame, the metalicy blue makes it look really nice, and how the frame has space in the middle and stuff. It looks awsome.

all i can say is WOW :astonished:

i bet you could really make some money sellin those

congrats on the awsome uni

Wow! Nice work! I can’t wait to hear how it rides. I can just see it now; you pull up next to some frat boys in a mustang who promptly call you names, to which you reply by asking them if they want to race. You then proceed to ride so fast that all of us catch up to you in age.

remember when some one posted the ticket from the police? We won’t see that from you because you’ll just run from the cops, and they will be powerless to stop you. Should they corner you, you can just shift into your secret trials gear and levitate above them. Make sure you grab one of their hats on the way up so you can indulge in a demented game of keep away.

Is Jagur going to threaten to move to Seattle now? If Jagur does move to Seattle I’m going to hold Greg responsible.

Re: Uni.5 43.5/29" two-speed shiftable unicycle

Very nice looking but what are you thinking man? Lascos?! Haven’t you seen
enough pictures of them blown to bits by just riding? Scot Cooper actually
injured himself on the last one he broke and SWORE he’d never use one again.
He was only going about 2mph on his Coker at the time! There was a recent
picture of one that actually broke into 3 pieces - not from huge drops, just
from riding. I have several pairs at home that people have slipped into my
garage somehow - they all go into the trash tonight and I suggest you do the
same.

Here is your replacement, tested by several of us, seems to work great:

43.5" wheel!!! YOW>! 20mph, no problem at
all, eh!

Harper

there is a new option to your crank arm problem.they just showed up on uni.com today.

http://www.unicycle.com/shopping/shopexd.asp?id=164

the color is kind of flat & ugly though,the Montys would go better with your sleek ice blue ride(tasty).

Boy is it gratifying to see that uni all put together - and what a relief to see that it all fits together! Harper’s AutoCAD drawings of the uni.5 hub were invaluable when making the frame for it. Pretty cool stuff!

Jagur - If you decide to move to Seattle rather than Idaho I’m sure John Childs won’t mind letting you sleep on his hide-a-bed for a while.

Steve Howard

I had 6" Euros on the original uni.5. The “Q” is a bit large. The Montys are about the right length and it looks like they’re straight so the “Q” is really low. I might even be able to get the unfinished ones anodized blue. Thanks for the tips, guys. I can’t believe I missed the Montys on the unicycle.com page.

I made the torque arm sleeve and pressed it into the frame tonight. The whole thing fits together perfectly. The shoulder bolt glides into either lock position. I rode it inside at the lab because it was dark when I finished. I have created a monster. There’s nowhere near enough room inside to ride this wildebeest. It’s incredibly fast.

oh i forgot to mention that whenever your ready to put this one in a crate and send it all over creation,i would like to be 1st on the list this time.

Only 97 more shopping days til Christmas.

Re: Uni.5 43.5/29" two-speed shiftable unicycle

Covet, covet, covet…bad dustin! Thanks for giving me something to dream about Greg and Steve…I’m talking about the Bluni.5 Harper :smiley: .

As far as cranks go, if you’re looking for 5 or 5.5 inch the Monty’s may be a bit long for you. Also, I think the 140 Monty’s only come in the darker version. You may want to check out the aluminium cranks at http://www.mys-co.com Here’s a link right to the cranks: http://www.mys-co.com/newSite/shopping/cgi-bin/shop.cgi?lang=eng

The pics of the Bluni.5 look great, my only complaint would be the long axle. Any chance that could be shorter so the cranks rest closer to the frame?

Powdercoating is always an option Greg. If you can’t find anyone locally to do it for you, then just order them from unicycle.com, have them shipped to my house, I’ll have them powdercoated, and shipped back to you.

I posted some views of the hub locked in 43.5" or 1.5:1 mode. This is the state in which I rode it this evening. Tomorrow is the long test ride and time test for changing modes. Shifting seems hardly an appropriate term.

http://www.unicyclist.com/gallery/albun23

Thanks for the links to the Japanese cranks, Dustin. Are they a pain to order? How’s shipping?

Thanks for the powdercoating offer, Adam. Is it a tough finish for cranks? The Montys look like they’re bead-blasted so they may be roughed up nicely to begin with.

Which songs can the Bluni.5 play? Can it do ragtime too or just the blues?

I’m going to begin having everything powdercoated. It helps prevent rust, due to the light layer of “plastic” being put over the metal. Cranks should be no problem at all. Wait until I have my translucent orange over chrome Profile 170mm cranks. :slight_smile:

Re: Uni.5 43.5/29" two-speed shiftable unicycle

Remember, we missed having a Washington State Records day this year–due to all
the other events going on. Maybe now we can organize a little Blue Harper Demo
Day–maybe in North Bend. I have a feeling we’d get about a hundred people
who’d love to drool on your machine.

Shall we try to pick a date? I’m not moving to South Dakota until it gets good
and cold there.
