Guide to “Fat” Electric Bikes

Posted by Tom Lee on

What is a “fat” electric bike?  Well it’s basically the monster truck of the electric bike world!


These “fat” e-bikes generally have tires that are 4+ inches wide and they are designed to handle all sorts of terrain like snow, sand, rough trails, the urban jungle (curbs, stairs) and anything else you can think of.

Because of the large volume of air these tires hold you can run the tire pressure extremely low and these tires will conform to almost anything you rollover.

The fat tire mountain bikes have been popular in the conventional bike world but adding electric assist really makes these bikes a lot of fun to ride!

If you’re looking for a bike they can handle any kind of terrain and will get you a lot of looks around town then you should definitely check out the new “fat” electric bikes!


Here is a guide to some complete electric fat tire bikes as well as some other fat tire bikes that you could add an electric kit to:
