Electric mountain biking is all the rage, and there are countless brands offering a range of fantastic assisted rides. From beefy, gravity-defying machines to lightweight all-rounders, ultra-expensive models, to more affordable bikes.

As technology rapidly improves, e-MTBs are morphing as well as diversifying. There are bikes with massive batteries and much-improved range, but there are also super light ones that provide just a little assistance while remaining close to the weight of a normal mountain bike. The choice is yours: are you a full turbo or fast and nimble kind of rider? Regardless of your usage pattern, we are here to help you find the best electric mountain bike which helps you conquer every road, no matter the roughest ones.

Types of Products

For clarity, the e-mountain bikes are electric-motor-equipped bicycles that only go forward if you pedal them. Officially, they are categorized as Class 1 e-bikes, which means they have no throttle and a top-assisted speed of 20 miles per hour. 

After you choose that kind of e-bike you would like, contemplate that category you favor. In the US, there are 3 categories outlined by the kind of assist and the way the motor can propel you. Most electrical bikes sold-out square measure category one or three. category one bikes have a motor (max 750w) that assists whereas you’re pedaling, up to twenty mph. 

Class 3, conjointly referred to as “speed pedelec,” may have up to solely a 750w motor (aka one horsepower). However, it will assist you up to twenty-eight mph. Each square measure allowed in most states and cities while not the requirement for a license. Category a pair of models have a throttle which will propel a motorbike up to and maintain twenty mph while not having to incessantly pedal. Aventon’s Pace five hundred is technically a category three e-bike therein it reaches hurries up to twenty-eight mph, however it conjointly contains a throttle that A-one out at twenty mph (the most legal speed for a throttle).

1. Best electric mountain bike overall

ECOTRIC 26” Powerful may be a totally centered, I-have-someplace-to-be, don’t-get-in-my-way e-rocket ship with the aggressive pure mathematics to match. it's a full carbon frame and fork, Shimano crosstalk drivetrain and brakes, and an old master Performance Speed motor (that means that it superior out at 28mph). Even a lot of excellent news for the dedicated commuter: It’s compatible with vary Boost, that helps you to piggyback a 500Wh bosch battery to the already frame-integrated 625Wh Bosch PowerTube, virtually doubling your vary. and therefore the old master Smartphone Hub show, that is compatible with the COBI. Bike app via Bluetooth, helps you to charge your phone, stream music, get turn-by-turn directions, make calls, and track information. Don’t expect to haul a lot of on the rear rack; its size makes it pretty restricted. Perfectionists beware: If you can’t handle even the slightest smudge, the simply marred matte frame and fenders can drive you bananas

2. Best full suspension electric mountain bikes

ECOTRIC 20” Fat Tire provides it with a 28mph kick within the pants from Bosch’s Performance Speed motor. What makes this bike significantly awe-inspiring to ride is Trek’s front and rear IsoSpeed decouplers. These enhance the frame’s compliance and provide a lucid comfort improvement to the rider compared to an important e-bike with a rigid frame. They additionally facilitate the tires sticking higher to the road, that improves management and handling of this almost-40-pound bike, particularly in jarring corners. The Bosch motor provides many torsions to create climbs quicker and easier, and also the 500Wh battery suggests that you'll be able to ride with healthy assist while not varying anxiety. ECOTRIC 20” Fat Tire isn’t afraid to ride rough pavement, either. It fits up to 38mm tires, giving it tight gravel chops, and it’s prepared for a rear rack and fenders if you would like to commute or tour thereon.

3. Best value electric mountain bikes

Among the full-powered e-mountain bikes we’ve tested, the Macwheel has the most effective combination of value and performance. It’s heavy, like most of these bikes - about fifty three pounds - but this one feels easier to manage. It’s an extended, low bike with twenty seven.5 wheels, that corners well which you'll be able to ride with diplomacy. It’s nearly agile, that isn't however we’d describe most alternative e-mountain bikes. That’s appealing once you’re sound over a double or fighting to remain on your line through a garden. The Yamaha-made motor is good: It’s comparatively quiet and applies force swimmingly while not lag. The management unit lacks associate degree liquid crystal digital  display, that reduces litter. However its form limits wherever you'll be able to position it on your bar, creating it more durable to check the lights that tell you which one's power level you’re in and the way abundant battery you've got left.

Buying Guides

Despite having known about different types of mountain bike, knowing for sure what you need is still probably vague. This is the main reason for the article below, we will introduce you to what is special about mountain bikes and will not forget to remind you  of what to pay attention to when looking for the best electric mountain bike.

1. The brake 

Bicycle brake is an important and indispensable part for a bicycle. The bicycle brakes are responsible for ensuring your safety in the process of moving any situation. Bicycle brakes are divided into two categories: linear pull brakes and disc brakes. Nowadays, mountain bikes are equipped with disc brakes for their safety and effectiveness.

2. The disc brake

A bicycle disc brake consists of a metal disc or rotor, which is attached to the center of the wheel and can be rotated with the wheel fixed on the block. The brake cable is attached to the frame or fork with a pad that presses the spindles to brake. When the pads pull on the rotor, the wheel - and therefore the bicycle - is slowed down because the motion kinetic energy (motion) is converted to heat. Disc brakes can be activated mechanically by cable or hydraulically. 

Some best electric mountain bikes are equipped with disc brakes, for example, the Macwheel and if you need a more secure brake, bikes equipped with hydraulic disc brakes will be a good choice ECOTRIC 26” Powerful

One of the most important components responsible for supporting the entire mass of a bike is the frame. The chassis is made of many different materials to help minimize the bike's weight. Currently the two most common materials used in bicycle frames are aluminum and steel.

  • Aluminum frame

Aluminum is the most commonly used material on bicycle frames, aluminum is known for its high resistance to corrosion, and is very light (although not as light as carbon fiber). It also makes your pricing affordable. It's a popular choice for riders who have not paid over their budget. 

You can also easily drive a bike with this aluminum frame to save you a lot more energy. The aluminum frame is quite easy to repair, helping you fix the deformation of aluminum faster than other materials. Therefore the best applications of aluminum used on off-road bikes are most common. Some electric mountain bikes equipped with aluminum frames such as Ecotric Electric powerfull or ANCHEER Electric Bike

  • Steel frame 

Steel has been used in the manufacture of bicycle frames for a long time. But the use of steel in the bicycle industry is more commonly used in the low-cost segment, as aluminum is currently popular.

But that doesn't mean there's no place for steel in the bicycle world. It is still a popular material for the bicycle manufacturing industry. Using steel to make a bicycle frame is also less expensive than other materials, of course it is also thicker and stronger than aluminum.

Steel is quite durable with a high resistance to deformation, unlike other materials such as carbon and aluminum you can easily repair. Here  are some examples for those type of bicycle which you can choose such as ANCHEER Folding Electric or  nakto Foldaway

3. Wheel size 

First, let's talk about the size of the wheel. This size is the diameter of the wheel. There are three popular sizes available today: 26 ”, 27.5” (650b) and 29”.

  • 26" wheel

The most popular size among mountain bikes. This standard is defined starting from the American bicycle company and Ecotric Electric powerfull is one of the best choices for those bikes. Other selections which provide customers with advantageous experiences due to it’s high profile, double-wall alloy rims are lightweight yet durable is nakto Foldaway

The 26 "wheel has a rim diameter of about 22" (559mm) and the outside tire diameter is about 26.2 "(665mm). The 26 "wheel is highly durable, allowing the bike to move flexibly, easy to maneuver, but it has disadvantages with bad terrain and the grip can not be better than the larger diameter wheels.

  • 29” wheel

VECTRO Electric Bicycle is a 29” wheel bike which concludes an array of preeminent function. For most 29” wheel bikes, a rim diameter of about 24.5” (622mm), and a tire diameter of 28.5 ”(724mm) is a popular size which is used in racing and touring bikes. In fact, the terrain bike races for Cross-country (XC) bikes show that the 29 "wheel is more dominant than the 26" wheel due to its better ability to overcome rough terrain, higher grip ability. 

With these positives, the customers totally pay for NCM Prague Electric to own. The speed is higher, but its disadvantage is that due to its large size, the rim can not be stiffer, and the control ability is not more flexible than the smaller wheels. Currently, the XC, Enduro over-terrain races in the world are mostly using 29 ”wheels to increase vehicle performance.

  • 27.5 "(650b) wheel

With a rim diameter of about 23" (584mm), it can be said that 27.5 "wheel is an intersection between 26" wheel and 29 "wheel, taking advantage of the flexibility of the wheel. 

If you want to buy a bike crossing all types of terrain with no difficulty,  NCM Prague Electric definitely meets your needs or NCM Moscow Plus is a choice for people who have a little higher living standard. 26 "combined with off-road capability of 29" wheels. However, components such as ribs and forks manufactured for 27.5 ”wheels are still much less than those for 29” and 26 ”wheels. 

4. Gears of bike 

Simply put, the controller helps your car to transfer to the appropriate disc or ripper. You often listen to 24 speed or 21, 27 speed, so what do these terms mean? On a bicycle with front and rear disc, how does the front disc in the back do? Let's find out about the important part of this sports bike. 

For example, your bike is 24 speed  such as  NCM Moscow Plus which means there are 3 front discs x 8 rear wheels. So 27 speed bikes are very modern, 3 discs front and 9 inch back allowing cyclists to cross over all types of terrain. However, demanding your basic needs, 21 speed bikes totally meet your needs. In addition, the disc coordination also requires a certain law, if the wrong combination will cause a quick glitch, damaging your bike.


1. Should you choose a steel or aluminum bicycle ?

Should it be steel or aluminum frame is an endless debate in the bicycle world, based on personal preference. We will try riding on a bicycle with different materials that can help you evaluate the suitable advantages of the frame.

Steel is seen as a traditional pick that tends to be favored materials by renowned custom bike makers that can deliver lifelike rides like spring. Compared to aluminum, steel is also a relatively straight material for welding. You are more likely to find someone who can help you repair the damage to your frame on the road if it is made of steel instead of aluminum. This will be true to some extent but will largely depend on the skill of the welder as well as the severity of the problem.

A steel frame or an aluminum frame can be good for long journeys, which is for sure a metal chassis. Don't choose carbon or titanium frames as they are expensive and not as easily repairable as you might think.

In a nutshell, you should focus on getting a bike that feels comfortable to ride while getting assistance with maintenance services at the bike shops. Playing the bike will surely have questions that need to be answered. Please consult right from experienced motorists or bicycle experts to get the best support.

2. How to choose the right bike frame for you ?

Ideally for riders, you should stand and measure on the trunk of the bike a few inches away. A proper fit could allow riders to achieve maximum pedal performance while using less energy. As a rider you should have knee bends with the foot at the lowest point of the pedal on the pedal. It's best to try this at your local bike store or retailer before making a selection so you can find a fit for you.

3. Should you choose a bike with a fork or two forks?

Mountain bikes are divided into many types with different designs to suit the terrain. With simple terrains suitable for bicycles with a single-fork structure. As for the more complex terrain, it is imperative to design a rear fork to reduce the pressure exerted on the chassis as well as the force exerted on the back of the body.

In addition, there are countless differences between these two bikes. To better understand and buy the right off-road bike, you need to master the following basic knowledge so you can consider whether you should choose a mountain bike with a fork or two forks.

  • Weigh

If the rear fork is attached, it also means the weight of the bike will be heavier than the one with 1 fork. Not only the forks, but the chassis is more intricately designed with lots of fittings and axles added to ensure stiffer operation. For many high-end models, forks are made of lightweight and lighter material. You can also upgrade your bike's forks with no difficulty.

  • Terrain

Each type of mountain bike is tailored to the specific terrain. A single-fork off-road bicycle can only move through low slopes, low gravel plains, but cannot help you overcome obstacles and potholes. On more complex terrains the design of a 2-fork off-road bike with high-adhesion tires makes it easier to cross more complex terrain than a single-fork bike can.

For a professional off-road cyclist make sure it can be tricky to ride a fork. But with its rugged terrain, 2-fork bikes can provide an adventurous experience with a guarantee of safety

  • Control

The fork has a function to help the cyclist steer through the terrain better. It can give you complete control over difficult jumps or over obstacles such as downhill, biking through mud or rocky terrain.

The rider relies on controls, the navigation combined with the up and down movements of the fork to respond perfectly to the terrain they cross. The more complex the terrain, the more efficient a 2-fork bike is required.

  • Feeling of cyclists

Comfort is a must for every athlete on a journey. A comfortable ride is more pleasant when you use a 2-fork bike because it absorbs the vibrations caused by rough terrain as much as possible. Trails and rugged hilly terrain often cause cyclists to experience fatigue due to the pressure exerted directly on pelvic mist and slopes. When buying a 2-fork off-road bicycle, pay attention to the parameters on the rear shock absorber. The compression and elasticity of the rear shock absorbers influence how much or less pressure is absorbed, thereby knowing the comfort that the cyclist feels during each journey.

  • Speed

Compared to single-fork bikes, the two-fork terrain types can take advantage of them for better acceleration. The assistance of the rear suspension reduces the shock absorber, which helps the cyclist to focus more on speeding with less attention to the effects caused by rough roads.

4. What do new mountain cyclists need to do?

Mountain bikes are the first choice of many young people today. Professional cyclists can ride the bikes they want, but for a beginner to mountain biking, not all bicycles can ride. We would like to guide new riders on how to choose to buy the best electric mountain bikes.

  • Frame

When choosing a bicycle frame, you need to give the seller 2 parameters. They are your height and the height from feet to groin.

Since frames are now manufactured with good materials, there is not much attention needed. When choosing a bicycle frame, just note a few techniques such as the weld of the frame, the quality of the paint and the weight. To avoid buying poor quality knockoffs, beginners need to pay more attention to the code imprinted on the frame or embossed text size.

  • Fork

Full suspension mountain bikes often have a front and rear (full) shock absorber system to help give you a more comfortable and smooth ride. Because mountain bikes have a shock absorber, mountain bikes are often heavier and more expensive than regular sports bikes.

  • Brake

Full suspension mountain bicycles are usually equipped with 2 main types of brakes: disc brakes and hydraulic brakes. The hydraulic brake is better, more sensitive than the disc brake because it has better friction. Meanwhile, disc brakes are cheaper but safer and work quite well when riding in rainy conditions and driving on muddy roads.

  • Price

For the beginners of mountain biking, when first experiencing it, there are many people willing to spend a large budget to buy a good quality bicycle sometimes up to a few thousand dollars. But they certainly do not have the technical proficiency to make full use of the bike. With the initial training process, the best electric mountain bike can meet the demand. Therefore, before buying a mountain bike, you need to consult with your friends, experienced people or mountain bike salesman to avoid wasting money.

Final Thoughts

The ultimate choice for a mountain bike is none other thanECOTRIC 26” Powerful which is suitable for cycling enthusiasts, office workers and college students, providing more convenience for life with front and rear double disc brakes perfectly increase safety and controllability for bikers. If you need another mountain bike that's cheaper but still offers a great experience then  the Macwheel  is the best choice for you. 

Below we will summarize all the models mentioned above so that you will have a better overview of the product that we introduce. From there choose a bike that is right for you
