You can now buy a folding electric mountain bike that can handle all kinds of offroad terrain and inclines for the same price as a decent standard model mountain bike. Today, I’m writing a review of the top 4 folding mountain e-bikes that Ecotric has available.

Folding bikes are not a new concept, but a folding offroad fat tire electric mountain bike, well that is a new concept.  Electric bikes have come long and far in terms of cost and technical specifications in the past couple of years.  The new company Ecotric is leading the tech race when it comes to folding electric mountain bikes and an affordable cost.

So let’s dive in and get on with our best Ecotric Folding Electric Mountain Bikes Review

Transportation of Standard Mountain Bikes

If you own a mountain bike, whether standard or electric, you can attest that storing and transporting it is a daunting task. People who do not have enough room in their garages often resort to hanging the bikes on the wall or squeezing them behind the front door. This where foldable bikes come in very handy.

Folding offroad fat tire electric mountain bikes is gaining popularity because of their convenience;  A personal bugbear of mine is unpacking and packing back up 4 mountain bikes on our trailer. We love going out on the trail as a family but having the hassle of packing and unpacking the bikes after a long bike run is a pain in the ass.

The Ecotric range of folding e-mountain bikes is just so innovative that folding and storing away is a breeze.  This feature alone makes buying one worthwhile, but the power, balance, look, and range of these awesome e-bikes by Ecotric are just awe-inspiring. But more on this later…

What to Look for in an Electric Mountain Bike

Before purchasing an electric mountain bike, here are some factors to consider.


Most e-bikes have a wattage that ranges between 300W and 500W. In most cases, a higher wattage translates to more engine power. However, highly-rated motors also consume more power and drain batteries faster. Most e/bikes with a higher wattage also showcase a higher performance compared to those with a lower wattage.

Maximum Power

Power is among the most crucial qualities of an electric bike. The amount of energy you need depends on the bike’s intended use. For instance, a hunting bike should have a higher torque rating that a commuting bicycle.


Most folding electric bikes have a hub motor instead of a mid-drive motor that is common in other e-bike types. This is because hub motors are smaller, meaning that they do not interfere with the folding mechanism. They also enhance portability.

Wheel Size

Wheel size dictates how small the e-bike becomes when folded. Most variants in the market come with 20-inch wheels, allowing them to fold into a size that fits in your car’s trunk. This size is perfect especially if you do not have a large storage space in your car. If you have limited space, you can get the 16-inch models, although they are rare.


How long do you plan to cycle? How expensive is a replacement? The quality of your battery cells is a critical aspect of any electric bike. Generally, the bigger the battery, the more expensive it is. High-capacity batteries also have a bigger range.

It is also worth noting that battery influences your bike’s performance. When the battery is located near the rear wheel, it is easier to remove but shits the weight to the back. On the other hand, batteries situated in the mainframe distributes weight evenly and improves handling, but it makes it difficult to install.

Component Quality

Many people tend to prioritize portability when shopping for foldable bikes and overlook the build quality. Ensure that the core components can suit your performance needs. You should particularly pay attention to the drivetrain, derailleur, display, and battery pack. A high-quality build will also ensure that the bike serves you for the longest time possible and you will also save yourself some repair bucks.

Size and Weight

This is perhaps the most crucial consideration when shopping for a folding electric mountain bike. Ideally, the bike should fold in a way that is small enough to fit in your space. It should also have a lightweight design. This as mentioned earlier ensures that you maximize the storage space you have efficiently.

The most impressive feature of the Ecotric Starfish is its huge load capacity, despite having a smaller motor than other e-bikes in the Ecotric range. That said, its 350W rear hub motor still produces enough torque to assist you through off-road conditions. However, the limited amount of power means that riding the Starfish on steep terrains requires more effort as compared to other bikes in the Ecotric range.

This model is great for very mild country trails and rides about town.  If you are looking for more hardcore offroad trail biking then one of the other 3 models would be more suitable.

  1. Great review, Martin.

    I love this concept and I have been looking at these bikes much more seriously of late.

    The issue is always their ability to climb and battery life.

    What type of charging process is involved? How much life does a battery have?

    Can the driver assist the electrical system when climbing to preserve battery life? Very informative and complete. I will forward this to my brother.

    Thanks, Paul

    1. Hi Paul.

      Thanks for your comment. To charge the Ecotric Electric Mountain bike is simple. You will be supplied with a charging adapter that plugs into the battery directly on the bike and then into the mains. A full charge after full battery drain is about 8 hours.

      You have full control over the pedal assist. Can be turned off or on with a flick of a button. So yes you can preserve the battery when you do not need the assist.

      I hope this has answered your questions sufficiently?

      Please ask more if you need any more clarification.



  2. Been on the lookout for a good e-bike for a while now but have not seen any that tick all boxes with regards to prices, portability etc. This seems to be pretty close to what I’m looking for in an electric bike, robust frame, fat tires, can fold, and does not cost a bomb.

    Defo going on my shortlist. Thank you for a very good review. Bookmarked for later.

    1. HI Aug,

      thanks for your great comment and glad I have helped you make up your mind on which e-bike to go for.

  3. I have been looking over your reviews on this ECOTRIC brand and done some more research on them also. Not too much info online but I guess that’s because they are pretty new right?  The electric mountain bikes they sell and in particular these folding electric bikes have really caught my eye.

    Not quite ready to buy one as yet but they are definitely on my ‘to buy’ list. Thanks for a really well put together review.

    1. Hi Sean. Thanks for the great comment and for taking time out to read my Ecotric Electric Folding Mountain bikes review.

      Yes, you are correct, Ecotric has not been around for that long but they are an awesome brand and a very trustworthy company.  

      Really top quality e-bikes at a very affordable cost.



  4. I’ve been in two minds about electric bikes but after reading your article I’ve noticed there are more pros than cons. Would you say getting an electric bike is generally more beneficial or does it all depends on what you use it for? For example, if I wanted to use it for fitness would it be better to get a normal bike?

    1. Hi Kurtes,

      Thanks for your comment.  If your main aim is for fitness then having pedal assist does not really make sense but you can turn it off and have the best of both worlds.

      There are hills you can tackle that you could not do on your own which opens up routes to you that you would not ever consider with a normal bike.

      So yes it’s great for fitness as you can turn pedal assist on and off when you please.
