Eunorau E-Fat-Step Description

As you probably know, electric bikes 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 have all these styles in a single ebike?

Welcome to the E-Fat-Step, the latest addition to the Eunorau (pronounced U-Nor-O) Ebikes lineup. This awesome ebike has 20" x 4" fat tires, which are perfect for off-road riding, including on dirt trails, gravel roads, city streets, and sandy beaches.

The E-Fat-Step is also an incredible bargain, and is actually featured in our review of the best, most affordable (cheap) electric bikeson the market today.

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 hydraulic 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.

  • How high is the step thru?

    About 13".

  • What is the maximum rider weight for this bike?

    250 lbs.

  • what is the wieiht of the bike

    66 lbs.

    Good E-bikes for Older RV Couple

    My husband and I are retired and traveling the US in our RV. We love riding bikes, but we both have a touch of arthritis, so we needed to get e-bikes to help us continue to stay active. Anyway, Steve was super helpful in talking us through how to find the right bike for our needs, and guided us to the E-Fat-Step, which just worked out perfectly. They fold up for easy storage, and have nice fat tires for trail riding. The low-step frame is really easy to get on and off of, and we find the controls are easy to operate. It's just like riding a regular bike, but with a boost from the motor and battery when you need it. Thanks again for all your help.

    I love my new ebike

    I'm not a big writer of reviews, so I will just say that this ebike has been life changing for me. I ride it every day and have already lost about 20 pounds. Very satisfied customer.

    Thank you Tina for your review. It's perfect.


    Betty’s bike

    After months of research, we settled on purchasing this bike. I love everything about it, especially the buttery yellow color! I am 66 years old. In my younger years, I participated in many long distance bike events. Then I got old and fat. I’m looking forward to getting “back in the saddle” and getting this old body back in shape!

    Really Good Ebikes

    Thank you for the kind review Betty. Riding an ebike is an excellent way to get in shape and have fun while doing it. So proud. Steve


    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.

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