Pumping up a fat bike tire with a conventional pump can be a cardio work out of its own. With that said, you should not be getting the same workout pumping up your fat bike tires as you do on the row machine at the gym! Enter the Topeak Joe Blow Fat.
As the first floor pump specifically designed for inflating gigantic fat bike tires, the Topeak Joe Blow Fat's barrel is beefed up by 50% to push big air volume to fill low pressure fat bike tires quickly and more efficiently.
This thing isn't your grandpa's Joe Blow, however it does hold true to its roots. In classic Joe Blow fashion, it features a steel barrel, a wide composite base, and an easy to read 15 psi gauge. Of course the TwinHead still flip-flops between Schrader and Presta with a thumblock lever for an airtight seal. Padded handle and sport ball needles included.

Pump does blow... very well. I use it as my primary pump for my MTBs since most of my tire pressure range between 13 and 30. Also use this pump to set up tubeless tires. Don't need my compressor for that anymore. Great product. Very solidly built.
PROS: Pushes Big Air, Comes With Cool Nipples, Durable, Easy to Use
BEST USES: Plus Size Tires, Setting Up Tubeless, Fat Tires
This pump fits the bill perfectly. I can get your air pressure right where you want it. It's easy to use. The gauge is easy to read and I can raise or lower my pressure within a 1/2 psi no problem. I wouldn't toss this in my pack on rides as it is too bulky to carry, but I can always use a small bike mounted pump to get me fixed after a flat and get it dialed in when I get down the mountain.
Currently using the standard Topeak Joe Blow, but only use up to 25PSI on the massive 170PSI guage. Bought this figuring it would help me dial in more accurately my 20-24PSI range for MTB tires. Guage is 4PSI off at 20PSI, and 6 PSI off at 30PSI. Jenson was helpful with a warranty pump, but unfortunately it was EXACTLY the same. This was cross checked with multiple stems, two different pumps and an independent gauge. I have a friend who recommended this pump, and his older one is indeed accurate. Not sure what the deal is, but this pump is completely worthless if the gauge is dysfunctional.
