iZip E3 Sumo | Fat Tire Electric Bike | Salt Lake City, Utah

If you like to ride your mountain bike year round, you’ll find snow and ice here in Utah can keep you down. For this reason, we sell a lot of fat tire e bikes like the iZip E3 Sumo to our Salt Lake City area customers. You’ll be able to ride anywhere and any time with these colossal tires.

The Bosch or Yamaha motors with torque sensing add that extra power to get up steep hills and ride over difficult terrain. And any limitations that come with fat tire bikes are minimized with the power-system.

Kurtis Downs, our sponsored pro, riding the iZip E3 Sumo, showing that with some skill and know-how, you can do just about anything on a fat tire e bike.

Some customers prefer suspension on their e bikes, and we can’t say we blame them. But you’ll find that the fat tires add the extra bounce and comfort that you typically see with shocks, making the price and features on this superior electric bicycle very appealing.

If you want front or full-suspension, consider the Haibike XDURO FatSix and SDURO FullFatSix.

Fat Tire E Bike with Walk-Assist

One of the coolest features that we love about this model is the walk-assist available on Bosch motors. Many hunters need to walk up a steep hill with their bike to the side of them. They don’t want to be pushing their heavy bike along. Walk-assist lets them push a button and their bike will move along with them at walking speed, without effort.
