find your FATWHEELS
To find the right set of FATWHEELS you must know the size of your bike and the weight of your rider.
How do I know what size bike I have?
Bike size is determined by the height of the tires. The size is printed on the sidewall of the rear tire. The first number in the sequence is the height of the tire - this tire fits a 29" bike.
about fat tire bikes
Fat tire bikes sit higher off the ground than typical bikes so you need to measure your bike's rear height from the ground to the center of the bike's rear axle nut and choose the appropriate kit.
Small FATWHEELS: Rear Axle Height Range (7 1/4 - 10 1/2")
Large FATWHEELS: Rear Axle Height Range: (11 3/4 - 15")

what are the best bikes for FATWHEELS?
There are four basic features that work best for compatibility with FATWHEELS:
"A" frame bike with a straight chain stay
Solid rear axle
Rear axle thread extends at least 3/16" past nut
Rear axle thread 3/8" X 24 or 26 tpi (threads per inch)
Multi-speed bikes with derailleurs
All FATWHEELS products are designed to accommodate bikes with derailleurs
Small and Large FATWHEELS kits including Upgrade Brackets will not work with bikes equipped with a Nexus shifter
Bikes with active rear suspension
FATWHEELS will not work on bicycles with active rear suspension
Bikes with quick-release hubs
The Small & Large FATWHEELS cannot be used on a bike with quick-release hubs - they require a solid rear axle.
The Small HD and Adult FATWHEELS are designed differently and can be used on bicycles with quick-release hubs.
FATWHEELS will not work with folding bikes.
Tandem bikes & tag-a-longs
We do not recommend that FATWHEELS bikes be used with tandems or tag-a-longs - they are designed to be used by a single rider on one bike.
Electric bikes or E-bikes
We do not recommend that FATWHEELS be used with electric bikes - our kits are not designed for higher speeds and should not be used at speeds greater than 6-10 miles per hour. If your E-bike has a frame design compatible with our product, we recommend that the bike be speed governed to a speed not to exceed 6-10 MPH.
