what is maximal speed on 24" and 26" without gliding, just pedaling
and what is common speed ( without trouble pedaling )
maximum speed=as fast as u can pedal
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.

iv got a gps on ma muni
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.
looks like i am wrong. Didnt think people would put them on…

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, and I tend to average between 8 and 9 cross-country.

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!
I’ve got a computer on my 24x3 Muni with 150’s and I’ve reached a max speed of 12.5 mph on quite a few occasions

If you pedal at a given cadence (rpm) then:
A 24 will be 20% faster than a 20.
A 26 will be 8% faster than a 24.
A 29 will be 12% faster than a 26. (45% faster than a 20)
A Coker will be 24% faster than a 29.
However, the cadence you can achieve will vary according to the wheel size, the length of your cranks, and your skill and confidence.
A 29er will hold 10 mph or more for real journey distances, but this takes determination.
A Coker will hold 12 - 15 mph for real journey distances, but this takes considerable determination.
A bicyclist making no real effort can average 10 - 12 mph easily for hours on end, and average 15 mph or more with only moderate effort.
10 mph = 16 kph.
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.

my speed
i have a torker lx and on a graval street i made 10.5 mph…as my average on my cycle computer the max was 14.6mph its the fastest ive gone on basicallly flat ground(not down hill any way) that graval road hat potholes out of the wazooo!
I got my coker up to 65 mph! Of course it was in the back of my SUV at the time!
thank you all very much it was very helpful
from this it seams that is not much diference in speed in 24" and 26"
but still theya re fast anough to follow my bycicle friends
now next question
is 24" or 26" better for municycling
by better i don’t mean easier
26 is better for the style of MUni that involves riding over broken or uneven ground and covering reasonable distances. Big wheels soak up uneven ground better.
24 is better for the style of MUni that involves very steep ascents and descents, and jumping, hopping or dropping over obstacles. Small wheels are lighter and stronger.
So 26 (or even 29) for the style of MUni that might be characterised as “cross country riding”; 24 for the style that some might call “trials riding in the non urban environment.”
This is a simplification, but is the general idea. Big wheels for rolling; small wheels for bouncing.
