He probably knows what maximum speed is, I believe hes asking what the
highest speed you can reach on either of those size wheels is. I dont
have a cycling computer so unfortunatly I dont have an answer.

I dont think you are going to get an accurate answer. Nobody will place
cyclecomputers on a muni. I could be wrong... But doubt it.

You can work it out with some simple maths.

The distance travelled by the wheel in a minute is the circumference
multiplied by the number of revolutions per minute. Multiply that by 60
and you get the distance travelled in an hour. Then it's just a matter
of converting units: inches to miles or whatever.

Circumference is the diameter of the wheel multiplied by Pi. (Pi =
3.14)

However, assuming you have no wish to do the simple maths, I have read
of speeds of 15 mph being reached on a standard 24. Brief bursts of
higher speed may be possible. A couple of years back I found I could
maintain about 9 mph for half an hour on a 24.

All other things being equal (cranks, rpm, etc.) then a 26 will be
about 8% faster than a 24. At these speeds, that's less than 1 mph
faster.

Average journey speed will depend on many variables.

I have a computer on my Muni, although the battery is flat at the
moment. I used it primarily for distance rather than speed.

i have already 20" uni for trials and street
becouse i'm the only guy here in croatia who drives uni i hang out wit
guys who drive bicycles and i found it veary dificult to follow them
while traveling around

so i was wondering to buy another uni for travel and i was wonderig
what are the speeds when you want to go fast and when you just drive
without overpushing your self so that i can know is it worth to buy uni
or some kind of bmx for traveling around the city and if it is worth to
buy uni to know the diference in speed in 24" and 26"

My top speed on my 26" muni is just over 12mph. That's for a flat-out
sprint over a short distance, not sustainable. I have had readings of
14mph a few times but I don't believe them, I think they're glitches.
Sustainable fast speed for me is about 9 or 10mph.

During the last French cup we ran a 10km race, It took me a little over
32 mins to finish it, so that's approx 18.5 km/h -roughly 11.5 mph.
Now the terrain was hilly and a bit rough in places, I think you can
easily reach 20km/h, with shorter cranks, flatter and smoother roads.
25km/h seems reasonable on a short distance w/ 110mm cranls.
EDIT : I forgot to mention that I was riding a 26" w/ a hookworm tyre
(far from ideal for races) and 125mm cranks.

I fitted some 3" cranks to my 26" and got a reading of 20.7mph on my
cycle computer. i was pedaling pretty fast though and i wouldnt be able
to keep it up for long!

We unicyclists try everything. I'm sure the first computer was stuck on
a unicycle within a year of them being on a market. I first installed
one in 1986.

On a 24", which is the standard size for racing, I've peaked at 17.5
mph. With shorter cranks you could go over 18. Not sustainable. I used
to be able to go 11-12 mph for an hour, but that's still on the high
side. That was in my heaviest training days.

Please note that those speeds are for a wheel that's actually less than
24" diameter, with 125mm cranks. A fat 24", like a Gazzalodi, is nearly
26" diameter, so can be pedaled faster. However it's also heavier, and
likely to have longer cranks on it, so average speeds will probably be
slower.

The biggest part in determining how fast you can go is you.

Most days I can go about 7-8 Kmph on my 20" but one day when I was
pumped full of adrenaline and going downhill most of the way, I went
1.7 km in about 7-8 minutes (timed from the time I hung up the phone
with my friend and the time I knocked on his door) this was about the
fastest I have ever gone on anything less than a 29er and I was also
quite lucky with traffic lights.

This was on a luna tire and 155 mm cranks so it is possible to go fast
just you have to spin those legs like mad to do it.

I put a computer on my 26", and mounted it on one of those retractable
keyring things that waitresses use so that I can read it whilst going
along. The only trouble is that you still have to hold it down pretty
low to read it, so the most I've seen is 12.6 mph before my bottle has
gone and I've had to look where I'm going. I'd expect it's probably got
up to about 14 or so, but my legs are going pretty wappy by then.
Around 10 mph is a reasonable cruising speed.
