Questions on buying a 28- or 29-inch unicycle

(1) I’m looking for advice on buying a 28- or 29-inch unicycle for pavement
and light trails. Which brands and models do you recommend (for example,
Semcycle vs. Yuni)? Are there other factors I should consider?

(2) So far, I’m leaning toward the “Yuni 29-inch Black with Kris Holm
Saddle” (http://www.unicycle.com/shopping/shopexd.asp?id=646).
Specifications from the Unicycle.com description:

Yuni gloss-black finish frame with chrome main-cap style bearing
housings
Odyssey GI seat post clamp with hex bolt
Seat post with 4-bolt pillar bracket (I think this is correct)
Suzue 36-hole high-flange cotterless hub
Bicycle Euro cotterless steel crank arms with black finish
700c rim with black-finish, double-walled construction, made of
lightweight alloy with nipple eyelets
Marwi stainless steel 14-gauge spokes with black finish and brass
nipples
Wheel hand-built in the USA by Kovachi Wheels (www.kovachiwheels.com)
WTB Nanoraptor 29 x 2.1 tire
European-style tube with Presta valve (order the Presta-to-Schrader
valve adapter if needed, by clicking on the link below)
Kris Holm contoured saddle
Union pedals made in Germany (I think this is correct)

Do you recommend any upgrades to the stock unicycle above (for example,
different pedals)? Any other comments about this unicycle?

(3) Is there a fatter 29-inch tire than the WTB Nanoraptor available? Is
there a wider rim available than the one above?

(4) Is there a 28- or 29-inch frame available that is wider than the Yuni?

(5) The crank length options on the unicycle above are 125 mm and 150 mm.
I’m more interested in speed than in leverage (I probably won’t have to deal
with steep hills often), although I would like control when I’m around
pedestrians. Should I go with the 125s or 150s?

(6) I’m not heavy and I don’t plan to do big drops on the unicycle, so is a
36 spoke wheel sufficient? Or should I look for a 48 spoke wheel if
available?

Thanks for your help!

Made a similar purchase

Hello:

I had the exact same questions on a thread a little while ago, sorry I don’t know how to link to it, but in essence it was as follows.

The Kovachi wheel is good because it is a standard size rim (700c) so you can get a variety of rims. The standard Semcycle is a funny size rim. The rim on the Kovachi wheel is narrow though, I don’t know if you can fit a wider tire than the Nanoraptor on it.

I wanted the black Yuni but at the time it was out of stock, so I got the Semcycle frame instead. I think these frames are built just about the same way and unicycle.com said they were similar in strength. I am 220 lbs or so and the only thing I have damaged on my Semcycle frame/Kovachi wheel is one of the plastic pedals.

Good luck.
Phil

Over here, the Yuni is called the Nimbus, I think.

The Nimbus 2 frame has a squarer fork crown which I think gives a bit more tyre clearance.

It makes sense to have a 700c rim, for the wider choice opf tyres.

Unless you are exceptionally heavy, or intend to do big drops, I’d expect any reasonable quality unicycle to stand up to quite heavy use. I’m only 145 pounds, but I’ve ridden my Nimbus 28 off road on skinny tyres and never had cause to doubt the rim.

I’ve got the Yuni 29 you’re looking at. I’ve never had any other 29, so I can’t compare. But this one is serving me fine.

Get both size cranks and don’t forget the wrench. But if $$ dictate, get the cranks that suits your terrain.

For road and light MUni, I use the 125. Fast enough for me. Can idle with concentration.

For more hilly MUni, I use the 150. Way more control. No prob idling, backwards, reacting to oddities. But feels sluggish.

I upgraded my pedals at my Local Bike Shop.

Check the Unicycle product reviews section of this website. I posted my Pashley Review there, and there is also a Yuni review. You will be happy to know that both uf us posters are satisfied customers, and a lot of my comments are simply musings concerning the 26er I didn’t get. carjug

Unicycle.uk.com sells basically the same uni with 125’s only. For
speed, 150’s are too long. You may need some getting used to with
125’s but then the control around pedestrians is probably good enough.

Is there a wider 700cc rim than the one on the Kovachi wheel? I’d like to
have the option of using the widest tire possible.

My rim has an inside width of 22 mm. It says 26x1.75/2.125 on the rim
strip, but the 2.35 Big Apple seems to fit just fine. (I should add
that I’ve only ridden it in one light ride of about 5 miles on paved
surfaces). I think a few more people have that combo. I don’t know of
a wider but almost-slick 29" tyre than the 28x2.35 Big Apple.

Strange that the rim strip says 26 because it is definitely a 28"
wheel. Also, the original tyre was less than 1.75".

Don’t worry about rim width. If I can run an Intense 24x3.0 tire on a Rhynolite rim you’ll be fine with that one. Just don’t do any 3 ft drops perpendicular to any slants and you’ll be fine. Have fun.

Just thought I should mention this, because I never read about it here:

If you have a wide tire mounted on a narrow rim you should always keep it at low pressure. If you inflate it to more than 2 or 3 bar (approx 30-40 psi), you risk that the rim breaks.

Schwalbe has some information on this:

OK, wide tires are generally for low-pressure use, but nevertheless one should keep that in mind… .

Where can you get the 28 x 2.35 Big Apple? Unicycle.com doesn’t seem to
carry it…

Also, does anyone else know of a wider 29" tire, or is this as big as they
come?

Thanks Juergen. I’d never given rim stress from tyre pressure much
thought but it’s something to keep in mind. BTW, that’s a nice
informative website that Schwalbe have there.

Where are you located? In the USA, your best bet is probably
<www.schwalbetires.com>. That web site is for the North American
distributor of Schwalbe tyres located in Victoria, British Columbia.

A couple of German websites to search for suppliers:
<http://www.schwalbe.de/> (Schwalbe is a German company; not sure if
this site leads to suppliers though.)
<http://www.utopia-fahrrad.de/15Jahre.html>
<http://shop.epple.org/>.

I got mine (in the Netherlands) via the LBS. They initially claimed
that it was unavailable in the Netherlands because the Dutch
distributor didn’t carry it. But after mailing utopia (see above), the
tyre was sent to that LBS through the intermediate involvement of a
company behind the e-mail address <info@anglodutch.nl>.

Hope this helps.

This may be a stupid question, but is the 29x2.1 Nanoraptor an inch larger
in diameter than the Big Apple 28x2.35? Or are tires listed as 28 or 29
actually the same size, since they both fit on a 700cc rim?

Also, is the Motoraptor available in the U.S.? It’s not listed on
Unicycle.com.

Re: Re: Questions on buying a 28- or 29-inch unicycle

There are two kinds of people. The ones who are confused about tire sizes at first. And the ones who don’t care about tire sizes.

700c is the rim size that fits 28" and 29" tires

Ideally a 28" tire is 28" in diameter, but since tires come in so many sizes this is just an approximation.

Tires that fit a 700c rim are usually about 28" in diameter so sometimes a tire (e.g. Big Apple) which fits a 700c rim is called a 28" tire even though it is actually bigger than some 29" tires (e.g. Nanoraptor)
