Are you looking for an affordable, portable fat tire folding electric bike? Well, check out the Fat-MN from Eunorau. This 20" x 4" fat tire folder is full of great features, and is perfect for trips around town, moderate trail riding, and even snow and sand.

Featuring a high-torque 500W rear hub motor, paired with a 48V/12.5Ah removable lithium-ion battery, Fat-MN is a powerful ebike. 

The Fat-MN features a 5-Level Pedal Assist System (PAS) which will help when you're pedaling uphill or against headwinds. There is a right-side Class 2 thumb throttle, which allows you to ride without pedaling. And the Fat-MN also has a 7-speed conventional gear transmission, which can be used alone or with the motor engaged.

Ask a Question
  • There were two different prices for the battery: One place that had the price with the bike, it was $300. Another place had the price at $500. Clarify please. Is there a discount if Two bikes are bought?

    Using the dropdown menu on the product page, you can add a second 48V/12.5Ah battery for $300, or a second 48V/17.5Ah battery for $500. If you buy 2 bikes, please use discount code SAVE5 at checkout to save 5%. Thank you.

  • Is there a manual for the e-bike? Are there instructions for the buyer to assemble the e-bike?

    The bike should come with a written instruction manual. We will check with Eunorau and post a pdf of the manual if one is available.
