Another Guy Considering a Fat Mundo...
So I've been reading up what I can on the fat Mundo projects, and thinking that might be for me.
My choice tire would be a fast off-road tire such as Knard, Small Block 8, Racing Ralph, etc. Floyds are too slick, Endos too knobby. From what I am aware of, there isn't anything in between 2.35 Small Block 8s and 3.8 Knards that isn't either an urban cruiser or aggressive DH tire. My thoughts were to fatten a thin tire or thin a fat tire through rim selection, if need be.
For chain clearance, I don't want to move the wheel to the side. I would rather go IGH or use a cassette with fewer gears. Though I don't want to sacrifice range, just the in-between gears.
So hearing all this, does there seem to be any hope for me? Or should my next step be therapy?
For my range of uses, I think so, but I'm still learning a lot. Is it correct that Knards are less knobby than Endos? If any of my comparisons are off, I'm up for being educated.
Endo is least knobby (very shallow chevrons). Then Larry, then Knard (or maybe 45Nrth Husker Du), then Nate. Endo and Larry are far less knobby than SB8, Racing Ralph

Welcome to the world of Fat Yuba
The sunlite 3.5 crusher tire will be available very soon, like a couple weeks or so. 3.0 kenda flames are legit even though they might seem corny because of the flames. 2.5 hookworms on 65mm rims are also legit. I want a nuvinci 360. you can get a floyd in the back but it will be too close to be practicle in my opinion. The best option in my mind is to go fat with rims, like 65mm or 80mm (yes they will fit) and go with either a hookworm or Flame. I will be trying the crusher tire as soon as they are available, I think they might work on 65mm rims which would be the ultimate if you ask me. Good luck.

Assuming I went with the 3.5, and perhaps 3" US choppers rims, what does that leave for gearing options? Part of me thinks I could survive with 3 or 4 gears in back at large intervals, but again I may be in store for some education. Open to IGH but hoping that isn't the only choice. I typically shift 2-3 gears at a time. Is that bad technique, possibly more so for a cargo bike?
I just saw that the crusher tires with the wire bead white sidewall stripe (they are going to have an all black folder too) are available now on j&b importers.

You might run into problems with the derailleur hiting the cogs if you try to make the jumps between cog sizes to big, this is because the derailleur moves in and down at a certain ratio and it might not move far enough down in the short distance it moves over when using a high range/low cog count cassette.
I personaly don't care for derailuers anyway, they destroy wheels, lives, families etc.
I would go IGH, But I have seen people run a tentioner, single cog in the back and a triple up front. I am going to do nuvinci with 65mm rims, I got the hoops from jbimporters and am waiting for a deal on the nuvinci 360. I will just use some custom machined axle adapters since nuvinci is 10x1 axle.
I don't think there is a right or wrong for shifting, just personal preference.
Do you have a Mundo yet?
I do not have a Mundo yet - I am still kicking myself for not jumping on their $400 frame sale.
Upon closer inspection, the Crusher tires seem to be for asphalt and sand only, and I was looking for something with a little more grab, at least around the edges. Though truthfully the vast majority of my riding would be an excellent fit for those tires. It's that detour through the park that's still beckoning.
