Guide to “Fat” Electric Bikes [VIDEOS]

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:

    Thinking that that would be the only way i would ride a Fat bike is with electric assist Pedaling all that extra rubber around for no other reason really then comfort would be tuff

    • Lynn Ellsworth says

      Bell makes solid rubber tubes for several size wheels.
      BUT they are terrible. They are heavy. If the tire is on the high end of the capacity the tube is suppose to fit you will feel that you are riding on flat tires. If the tire is on the low end of the tube capacity the Bell tube is suppose to fit you can NOT use a tire with a strong bead because it will be impossible to get the tire on the rim over the solid tube.
      If you want to waste your money (like I did) to experiment with the Bell solid tubes make sure you have very cheap and very flexible lower capacity tires that might fit over the solid tube and on the rim.

    I just bought a Salsa Beargrease X9, the new carbon 2014. I would like to put a electric support to this, and it need to be a pedal assist system. Does any of you guys have a suggestion?

    Best regards

    I bought a “Big ‘oL Fatbike” from Nashbar last fall, and I love the thing. It cost only about a thousand bucks. It was an arduous task to ride my bicycle across the dry lake bed where I live (Lake Isabella, CA), due to soft sand and soft mud in parts, but the bike handled remarkably well. Riding on the road was only slightly slower than my other mountain bike. I emailed Falco electric motors and their president promised that he has a hubmotor kit for the rear wheel that had a 170 mm axle width. That’ll be my next big ticket purchase for this year!!
