I Love It!

At my age the convenience of having a folder which I can carry in my trunk for easy access is priceless, and the low step makes it super easy to get on to and ride. The fat tires makes riding super comfortable despite my back problems. This ebike has changed my life for the better.

Thank you Tina. We really appreciate your review.

Fat tire bike

Long wait to get. Bike rides great , but battery lasts only about 20 miles. Should have a better battery.

Thank you for the review Valerie. I agree about the battery.

Weight without the battery

It says the bike weighs 65lbs. Is this with the battery attached to the bike or without the battery? It might be a bit heavy for me to lift in and out of my car to transport to the rail trails that I mainly ride on. Thanks

Weight shown is with the battery.

Great bike

First I want to say how great Steve was in helping me decide which bike would be best for me. He kept me updated on the delivery time since I had to wait a bit but it was well worth the wait he is very informative when you have a question I received the bike and it works perfect for me I am 64 years old with knee problems and had trouble riding my other bikes. It is easy to mount and I pedal with the assist and it gives me exercise and yet I get to keep up with my husband

Thank you Suellen. It was nice getting to know you, and I'm glad I could help.

Great Design and Function

I'm very pleased overall with my new ebike. My only complaint is that I had to wait so long for it to arrive. You should keep these in stock. Thanks.

Thanks Gordy. I completely agree, but my suppliers have had shortages because the coronavirus disrupted the ebike supply chain. I hope this will resolve soon.

Eunorau E-Fat-Step Description

As you probably know, ebikes come in many styles, just like regular bikes. You have fat tire ebikes, folding ebikes, step-through ebikes, and so much more. But what if you could all these styles in a single ebike?

Welcome to the E-Fat-Step, the latest addition to the Eunorau Ebikes lineup. This awesome ebike has 20" x 4" fat tires, which are perfect for off-road riding, including in sand and snow, or just the urban jungle.

It features a step-through frame so it's easier to get on and off the bike (especially if you carry stuff on the rear rack, it saves you from having to lift your leg over the seat). And, of course, it's a foldable ebike, which makes it more portable.

The E-Fat-Step features a 500W high-torque rear hub motor, paired with a 48V/12.5Ah lithium-ion battery. This long-range battery can quickly be removed from the bike to take with you or for remote charging.

To operate the E-Fat-Step, you have a 7-speed gear transmission, so it can be pedaled just like a regular bike. But there are also the 5-level pedal assist system (PAS) and a thumb throttle at your disposal. This gives you great flexibility for every riding condition. I should also mention that the strong mechanical disc brakes have automatic motor cutoffs, so when they are engaged, the motor will stop working - a great safety feature.

Please watch this video of a woman riding the E-Fat-Step. In our opinion, the bike looks too big for, especially the reach which forces her to keep her arms up and stretched out. Use this as a guide to make sure the E-Fat-Step is not too big for you.

Ask a Question
  • What is the speed and range of the bike when using the 17.5Ah battery? Can that be increased at all?

    The maximum motor speed is 20mph, but you can ride as fast as you like using pedal power. The 17.5Ah battery has an average range of 42 miles per charge, based on our ebike range calculator. The bike comes with a 12.5Ah battery, which has a range of about 30 miles per charge, and you have the option of getting a second battery with a 12.5Ah or 17.5Ah capacity.

  • I am 5'2" with short arms 26 inches from shoulder to the tips of my fingers will the eunorau step through still work for me.

    The minimum seat height is 31.5", so it might be a little tall for you. Check out the video on the product page - it shows a shorter woman riding the bike and you can see how it fits her. The Runabout is another option for shorter riders, although it is not fat or a folder.

  • What is the dimension from ground to top of bike seat in it's lowest setting?

    The minimum seat height is 31.5".

  • Can I purchase the 17.5 AH battery in place of the standard 12.5 Ah battery?

    I'm sorry, but the option are to add an extra battery, not swap out the battery for a larger capacity.

  • How much is a spare battery for this bike and how much does it weigh?

    The replacement battery is usally about $500 and weighs about 9 lbs. But we are not in stock at the moment.

    About 13".

  • What is the maximum rider weight for this bike?

    250 lbs.
