The Best Electric Folding Bikes (Of 2021)

Best Folding E-bikes

Folding electric bikes are the epitome of urban practicality, making multi-modal commutes not only possible but also very practical.

There’s an important reason why the number of folding electric bikes is on the rise on city streets—they work. A folding bike is functional as it gives you all the capabilities of a regular bicycle but makes transportation and storage a lot less of a hassle. Add a motor and a battery to it, and it becomes accessible to a lot of people out there who are looking for more efficient ways to commute.

So whether you’re interested in folding electric bicycles as a way to commute or you’re looking to save space in your home, we’ve found and reviewed the best folding electric bikes on the market.

But before that, here’s some important information on what to look out for when searching for a foldable electric bike to meet all of your needs.


Are Folding Electric Bikes Any Good?

Contrary to popular belief, folding electric bikes are fast, nimble, and practical. They can go as fast as regular bikes, squeeze through traffic jams, and they’re easy to store and transport. Plus, thanks to the motor, you can travel longer distances, without getting too tired.


What to Keep in Mind About Motors?

For practical purposes, most folding e-bikes come with hub motors. However, there are some exceptions, including a few models on our list, that have mid-drive motors.

The reason why hub motors are the go-to choice for electric mini bikes compared to other types is the lack of space. Folding electric bicycles are small, compact, and need to remain that way to fold small. If you add a mid-drive motor, folding will not be impossible, but it takes more engineering to develop an efficient folding mechanism.

Hub motors can be placed in the front or in the rear wheel. But in most cases, you’ll see hub motors in the rear wheel, as this is a much better solution.

Front-wheel hub motors are cheaper to install, but they have a few disadvantages. Namely, they affect the bike’s handling and don’t offer as much traction.

When riding a bike, most of the rider’s weight is on the rear wheel, so the tire has plenty of grip and won’t skid if you apply a lot of torque. On the other hand, the front wheel might spin out if the motor is too powerful and there’s not enough weight keeping the tire in contact with the ground.

Of all the available options, mid-drive motors are usually the most powerful and offer the best riding experience. They provide assistance directly through the pedals, so you have a good feel of how much of your own power you need to apply.

But in addition to the motor placement, you also need to think about power—watts and torque.


Watts—Is There Such a Thing as Enough?

Electric bike watts

If we assume that Watts=Power is correct, we can conclude that the more Watts your foldable electric bike has, the better. But that’s not completely true for a folding electric bike. Due to smaller wheels, you don’t need that much power to feel like you’re getting somewhere. Too much power can even be dangerous as the small-diameter wheels are not as stable as larger ones.

The majority of bikes on our list have either 250W or 750W motors, but there are a few 500W models as well. The wattage depends on the amount of assistance you require, but it also depends on your country’s e-bike laws. For example, in the UK, e-bikes are allowed to have 250W; in the EU, e-bikes can have up to 500W motors; in the US, e-bikes are limited to 750W.

But wattage is not the only metric you should be worried about. You should also consider the torque. A 500W motor with 40Nm or 80Nm of torque is not the same. More torque means that the motor will have more immediate power, climb better, and offer faster acceleration.

Keep in mind that more Watts and more torque does not translate to a higher maximum assisted speed. Most folding e-bikes are Class 1 and Class 2 e-bikes and are thus limited to between 15–20 MPH. The only exception is Class 3 e-bikes or speed-pedelecs, which can go up to 28 MPH. But these are rare in the folding world.

As a rule of thumb, if you are a heavier individual or you live somewhere hilly, you should look for a motor with more power. A 250W motor with little torque might struggle to pull you up a steep hill.


Which Wheel Size Is the Best?

E-Bike wheel sizes

Wheel size is one of the main considerations when choosing the best folding electric bike for you. The smaller the wheel, the more compact the bike will be when folded. However, small wheels come with some limitations, especially when it comes to the terrain they can conquer.

Most electric mini bikes have 20″ wheels, including the models on our list. This wheel size offers a good compromise between practicality, stability, and rolling efficiency.

If you want, you can go even smaller and choose 16″ wheels, but keep in mind that you’re limiting yourself to the choice of terrain you can ride on. Such small wheels won’t feel stable on pretty much anything but completely smooth city streets. Also, they don’t roll over bumps and rocks as easily, so comfort is affected as well.

Small wheels mean that you will have to pedal a bit more to reach a certain speed. But that is not a big problem considering you’ll be getting assistance from the motor.

Those who don’t want to compromise on speed and pedaling efficiency can choose a folding bike with full-size, 700C wheels. But keep in mind that such bikes don’t fold down as small as models with smaller wheels. Thus, storage and mobility become bigger challenges.

To sum, if you’re uncertain, go for 20″ wheels. They’re the gold standard when it comes to folding electric bicycles, as they combine the best of both worlds.

FULL REVIEW of Rad Power Bikes

Rad Power’s RadMini is a versatile folding fat-tire electric bike with a suspension fork, that can conquer different types of terrain. You can use it equally well for city commutes as well as for off-road gravel and dirt detours.

It folds down quickly and in a few steps—its folded dimensions are 41″ x 22″ x 28″. However, it also comes with a 67 lbs. weight, so it takes some effort to carry it up a flight of stairs.

RadMini is equipped with a 750W geared rear hub motor that delivers 80Nm of torque. Therefore, power will not be a problem. The range shouldn’t be either, considering the massive 48V, 14Ah (672Wh) battery with Samsung cells. According to Rad, you can expect up to 45+ miles on one charge.

RadMini is a Class 2 electric mini bike so it has both pedal-assistance and throttle. Its maximum assisted speed is limited to 20 MPH, which is more than enough for an efficient commute.

When it comes to the mechanical parts, this folding electric bike has a 7-speed Shimano drivetrain to make pedaling more efficient. It also comes with an SR Suntour 60mm suspension fork that will improve comfort and stability.

The package also includes fenders, a kickstand, battery-powered lights, puncture-resistant tires, and a few other perks.

Tern GSD S10 is a one-of-a-kind cargo folding electric bike. This is the ultimate utility vehicle for parents with kids or big families that make huge grocery hauls. If you want to drive your car less, this Class 1 foldable electric bike is the way to go.

The thing that excites us the most about this folding electric bike is the integrated cargo area. It can easily carry two kids or a week’s worth of groceries. The total weight limit including the rider is 440 lbs., which is a lot considering the size of the bike.

GSD S10 comes with a high-end Bosch Performance Line 85Nm mid-drive motor coupled with a 400Wh Bosch battery. This is a reliable setup that ensures a 20 MPH maximum speed and 26 – 53 miles of range.

Tern built the GSD S10 around a durable 6061 aluminum frame and also equipped it with a Shimano Deore 1×10 drivetrain, hydraulic disc brakes, fenders, and a dual kickstand.

It’s important to note that this bike does not fold fully. It allows you to lower the saddle all the way down and fold the handlebar, so you can store it more easily. But the frame itself does not fold.

All in all, Tern GSD S10 is the best cargo folding electric bike a family can dream of having. It solves the mobility puzzle, saves money in the long run, and adds a layer of fun.

This bike offers five levels of assist, plus a throttle. If you use them smartly, you can get up to 40 miles of range out of the battery.

Though Aventon Sinch folds quickly and completely, the folded dimensions are not super compact because of the wide 4″ wheels—41″ L / 23″ W / 31″ H. Plus, the bike is not ultra-light at 68 lbs.

However, if you’re fine with the higher weight and larger dimensions, Sinch will save you money and do all the things more expensive folding e-bikes do.

What Should I Look For in a Folding Electric Bike?

You might have experience with buying bicycles, but purchasing a folding electric bike is a bit more challenging. In addition to all the standard features you need to consider, you should also think about the electric components and the folding mechanism.

The folded dimensions should be small enough to fit your car’s trunk or the storage space in your apartment. Most models nowadays have easy-to-use folding mechanisms, so that shouldn’t be an issue.

A good folding electric bike should be compact, light, practical, and easy to fold.

Next, you should think about the motor and the battery. If you live somewhere hilly or windy, you should get a more powerful motor and a bigger battery. Also, choose between a hub and a mid-drive motor. The former is cheaper, but the latter is more stable because of better weight distribution.

If it often rains in your area, consider better-quality hydraulic disc brakes as well.

We’d also recommend paying attention to the wheels and tires. Big wheels are more stable, but they increase the bike’s folded dimensions. If you plan to ride off-road, choose a folding fat-tire electric bike, such as RadMini or Aventon Sinch.

In the end, look for a bike that you will find practical to use every day and that will thus significantly improve the quality of your life.
