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.

    Excitement Overload

    If you are looking for a great fat tire folder, the FAT-MN is a great find. I search around for a bit before I stumbled on this beauty. The quality of this folder is what stood out to me above the rest. The price is not bad either, can't wait to get my bike next month.

    Love Love Love This Ebike

    Love love love this bike! I don’t have great balance when starting to pedal and using the throttle makes this so much easier! I’m able to go up hills which means there are so many more bike riding options.

    Great Fat-Tire Folding Ebike

    This compact folder is exactly what I needed. After looking around for a bit I decided to get this portable folder from Really Good Ebikes and I am so happy that I made the right choice. It is perfect for off-road trails around my neighborhood, It was within my budget and the fat tires on this bike allows me to ride even when it snows.

    Perfect Fat Folder

    I know there are a lot of similar fat folders on the market, but I was really impressed with the build quality of the Fat-MN. That, and the fact that it was in stock. Thanks for taking my order by phone.
