I saw a fat bike with 29 x 4.0 inch wheels. I am told it was made in Taiwan. Expect these to become common in the next couple of years.

I've already been wanting one for over a year, so...

Fat bikes peaked in 2015 and their sales have declined ever since. I don't ever expect them to become "common," regardless of tire size.

There are supply problems to North America. Where I am, you can walk into the shop and buy one.

I am curious to know whether others have seen 29 inch fat bikes, or whether there are very few out there yet.

I see a chicken and egg problem - manufacturers will be reluctant to make a 29" fat bike until 29" fat bike tires are common enough, and tire manufacturers will be reluctant to make 29" tires until 29" fat bikes become more popular.

A big company (e.g. Quality Bicycle Products) needs to jump start it.

Why don't you ask the mods to move this to the Fat Bike section? That way you can get input from folks who are interested in fat bikes. On the other hand, you'll get yourself more attention if you leave it here. Just depends on what you want from your thread.

I'm wondering what will be the preferred jockey wheel size on a 29" fat bike.

But if I put a motorcycle mirror on it and swap out the top quality Shimano derailleur for say this really awesome one that cost 2.50 and I only have to replace it every 6 months...

It is happening. This is what I am talking about.

brands of 29" fat tire bikes?

alo

This one was X-treme. I don't know all of them.

I believe they are manufacturers based in Taiwan.

America has a delay on deliveries. But I would expect 29 inch fate bikes in America next year.

but did you waive at them? It's not official unless you waive.

The biggest market will be FAT E-Bikes. Able to pass those skinny tire road bikes with the touch of a switch.

I can't say if the larger tires will be widely adopted.

It was a Site Admin that made the #2 post here.

I don't believe they make 4 in. fat tires for 29 inch wheel. Post a link with specs. to prove yourself.

I'm seeing several 29x4 rims on E-Bay, but I'm not finding any tires. Of course, who knows what would be shipped.

A couple of Google hits on 29x4.0 tires from China, but listing marks 26x4.0 & 29x4.0. So, who knows what they have.

29x3 is relatively easy to find.

29" fat bikes: mudguards or fenders?

Someone correct if I'm wrong, but I've never come across 29 inch bicycle wheels. 29 inches refers to the approximate tire outside diameter, but 29er tires use the same 622mm diameter rims as 28 inch/700C tires do (width may differ though).

As for fat bikes, as far as I know, they have the same rim diameter as regular 26 inch tires (559mm), but the outside tire diameter of the 4 inch tire comes to roughly the same as regular 29 inch tire.

I bet OP seen a bike with 27.5 wheels and 3.8 inch tires and he thought that it was a 29'er...

CliffordK

Yeah, mostly true.

Part of the reason we have a mess with 26" (and some other tire sizes) is the 26" refers to the outer size of the tire.

So far 29" has been defined as using a 622mm bsd rim.
And a 26" Fat Bike is defined as using a 559mm bsd rim.

Hopefully someone doesn't come along and redefine the sizes... well, just because.

It would be sensible whenever they bring out a new size, to make it something standard. For example, they could have a 500mm rim, a 600mm rim, and a 700mm rim. To change it now, would result in too many sizes, but if they had a standard system from the beginning, it would be simple.

If they used the same standard as they use for cars, trucks and motor bikes, the 26 inch would be called 22 inch, and the 29 inch would be called 24.5 inch. But this would confuse people.
