Where are my fat bike riders?

Man, I just picked one up two weeks ago...and I LOVE IT!

I used to amateur race MTB, and had a ton of fun. My MTB is still in the garage...and I actually just upgraded the tires and brakes again. In the last two years I have switched to road bikes...and have really enjoyed pounding out some very quick multi-mile trips on a much more efficient ride. Moving once again into winter I wanted this year to keep riding...and so began my search into fat tire bikes. I finally pulled the trigger on one...and even though there has not been snow yet, I have not spun a wheel on my road bike in the last two weeks, and I don't see pulling the MTB down off the rack. I love riding my fatty! The best part is that I live on gravel, and close to "level B" roads...so I can just hop on at my front door and go! No more loading up the bike for a trip down the gravel to find some pavement.

Yes, my distances are less, yes my pace is slower (just over half), but I am having a ton of fun, and keeping my cardio up as we turn into winter. What a blast!

PS...running around 20PSI and already had a flat from a thorn...normal to have higher flat tire rates of a fatty? I already bought several tubes to keep her running...just wondering if that is normal to get one so quickly?

First off, pics or it didn't happen. And brand and model is always welcome if no pics so we know what you're talking about.

I've been riding a 27.5x3.0 mid-fat(+) for 3 years and run 12-13 front and 13-15 rear, if you're riding a true fatty, 4.0 or more you're way over inflated, the whole point of the fat tires is the low pressures you can run. Go tubeless if you can, you'll never look back.

Go to the forums on mtbr.com, there's one for + bikes and one for fat bikes.

Big tires are a hoot!

Edit: if thorns are a problem and you want to run tubes then by all means get Slime or Stan's sealant.

Those look like 4" tires. Do some research but you'll probably want to be running under 10 psi in the snow, 10-15 trail riding and 20-25 gravel road riding. 20 psi on dirt defeats the purpose of the fat tires.

they are 4" tires...and all but about one mile of my ride are gravel roads...so I thought ~20psi to be appropriate.

The hottest new bike of the past couple of years is the gravel bike, basically a road bike with 45mm wide knobby tires and disc brakes, for riding fast on dirt (gravel) roads. Did you check them out?

You bought a Jeep with big tires, these are rally cars.

I did, and my mountain bike seems to fit that bill when I put crossover tires on it. I got the fat bike to keep riding in the winter - in the snow and ice that we are already getting here in Iowa. Fat bikes excel in those conditions.

20 psi is way too much for fat bike tires. You want the sidewall to bulge a little bit when you ride the bike to increase the footprint, if that makes sense.
I'm in full agreement with you about fatties being so much fun. I used to ride a full suspension 29er. Around 2011 or 2012 I got a taste of fat bikes and now I won't ride anything under 3 inches wide.
To address your thorn... You need to go tubeless. I believe that bike comes with Weinmann rims which are not really suitable for tubeless. It's a bit of money but if you want to have trouble free riding and maximum traction, tubeless is where it's at. When they're available, Alex Blizzerks are excellent, cost effective rims. They do tubeless perfectly. I've been riding tubeless since around 2009 and have never had a flat since. My fat bikes have only ever been tubeless. No issues.
I run 5" tires on the bike below. I run 9 psi in the front tire and about 11 in the rear. Less for beach sand or snow. Don't be afraid to experiment a little.

What bars are you running NYE? Due to wrist problems I'm running carbon Answer 20/20s on my + bike and Origin8 OR2 bars on my 26" converted gravel bike and won't ever run shallow bend bars again. Tubeless is the real deal but the OP shouldn't have any more or less problems with his 4" tires than any other. Slime or Stans.

I run Jones H Bars on all of my bikes. I have a poorly done right forearm repair and straight bars make my wrist hurt after a short time. Now, I run the Jones Loops with 2 1/2" of rise. Great bars plus, they have an awesome space for a bag.
Lots of people say the Jones bars are for touring and you can't ride singletrack with em. It took me a few rides but now I can ride the gnarliest tech with them just fine. My fifteen year old son runs em too.

I was going to post the same thing. 20 psi is way too high.
If you're not riding on snow or sand 15 psi is probably the most you'd want.

Also, lower psi = less pressure between the tire and the ground because your weight is spread out over a larger area which generally means less chance of punctures (less force to push sharp things through the tire).

Tubeless is an option if you ride your bike a lot but it's a bit more maintenance-heavy than tubes (the sealant dries out over time and the tires lose pressure faster between rides).
