Frequently Asked Questions

What is a Fat Tire Electric Bike?

Fat Tire bikes are fitted with 4.0 inch wide tires. These”fatter” tires provide additional traction and stability which makes our bikes safer. Fat Tires are considered ‘go anywhere, anytime tires’. They can handle terrain most bikes would not be able to navigate. Rain, snow gravel, sand and potholes are no match for fat tires. The increase in stability is instantly recognizable when you ride a FattE-Bike. Our fat tires also make the rider more visible to other cyclists and motorists. This additional visibility also contributes to the safety of a FattE-Bike.

Where can I find FattE-Bikes?

FattE-Bikes was born in Denver, Colorado and is proud to be Denver’s first electric bike manufacturer. Our storefront and manufacturing facility is located at 2596 W Barberry Pl Denver, CO 80204. We also have our online store at  Currently we are growing to more retail partners in Colorado and beyond.  Our retail partners page of where you can find FattE-Bikes outside of Denver is coming soon!

Where are your fat tire electric bikes built?

We're proud to say that our FattE-Bikes are built right here in the USA. Our headquarters are in Denver, CO where we do full assembly, powder coat painting and complete customization of our bikes. FattE-Bikes is one of the only electric bike companies in the country to build our bikes in the USA. This gives us higher quality control over our products while enabling us to offer more colors and custom options as well as be able to provide better care and customer support to our FattE-Bike community.

What class are your Ebikes?

Our FattE-Bikes can be ridden as a class II OR class III ebike. You're in control of the speed settings. We send most of our bikes out as class III as they're able to get you up to 25+mph or so with ease. However, if you prefer it to be class II then it's a simple adjustment with your LCD which would cap the top speed at 20mph.

What type of throttle is it?

We use a half twist throttle that includes an off-switch if desired. Some companies will opt for a thumb throttle, however in our experience, thumb throttles can quickly wear out your hand and are more difficult to maintain desired speeds. More importantly, thumb throttles can be more dangerous as when using your thumb it forces you to release your 5 finger grip down to a 4 finger grip (since your thumb is now on the throttle). This can cause serious hazards should you hit a pothole or need to make a quick reaction for some reason. If your hand were to slip off, it won't end well. This is why we use a twist throttle and the same reason why motorcycles and scooters use twist throttles as well. You maintain a full 5 finger grip at all times, your hand doesn't get tired and you have greater control over your speed.

Do I need a license or permit?

No! Our FattE-Bikes are classified just like a regular bicycle and therefore do not require a special license, insurance or anything else that a scooter or car requires. This also gives electric bikes access to most bike paths and other places that vehicles can’t go. That said, FattE-Bikes recognizes that laws can vary in different municipalities therefore we recommend checking local regulations before riding. Feel free to reach out to us for additional information.

How fast can an electric bike from FattE Bike go?

In order to be classified as a bicycle and not require a license, motors for all our ebikes have a top speed of 20-27 MPH depending on the model. However, it is possible for the rider to go faster by only using their own pedal power.

How far can I go on a single charge?

Average riders can go up to 65+ miles on a single charge, depending on which of the 2 choices of battery we offer (48v 14.5ah/19.2ah). There are a number of factors that influence the range, such as the weight of the rider, the amount of power they choose to use while riding, the terrain they ride such as hills vs flat terrain, etc. Most people do not commute this far and can easily manage their daily riding on a single charge. However, for greater distances we make sure to provide a charger that’s light enough to carry around. Of course all FattE-Bikes come with a battery monitor so you’ll always know when you need to charge your battery.

Do I need a special outlet to charge the battery and how long does it take to charge?

You can charge your battery anywhere! Depending on the battery size they can take anywhere from 4-8 hours to fully charge on our chargers included with the bike, using a standard 110 volt outlet. If you purchase a high speed charger, typical charging times are cut in half.

How long will the battery last?

Our batteries are rated to last about 600 full charge / discharge cycles.

Is there a height and weight limit?

At this time our bikes are best suited for anyone 5’0 – 6’5. To see measurement specs go to bike model of choice and click on measurement dropdown menu for more information. Our bikes have a manufacturers suggested weight limit of 285 lbs but heavier riders weighing up to 350 lbs have still fully enjoyed using our bikes. *

*Anyone over this weight limit takes full responsibility and if there are any mechanical or bike issues that develop as a result, FattE-Bikes is not to be held liable. 

Do I have to use the motor?

No, you choose when to engage the motor. You can either turn your LCD off and pedal or keep your system on and turn your PAS to 0.  It doesn’t matter whether you’re using the PAS (Pedal Assist Sensor) or throttle system, the motor only kicks in when you decide. If you choose not to use the motor your FattE-Bike will operate just like conventional bicycle. However, electric bikes can weigh as much as 70 lbs, so even though you don’t need to use the motor it will take a little more effort to get around.
