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 about...?

Multi-speed bikes with derailleurs

All FATWHEELS products are designed to accommodate bikes with derailleurs

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


Folding bikes

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

We do not recommend that FATWHEELS be used with electric bikes - our kits are not designed for higher speeds.
