What Should I Look for When Buying an Electric Mountain Bike?

You need to know what to look for before making a confident decision. Here are the tips to use in your quest for the best electric mountain bike. 

Frame Construction and Speed

While the focus of most e mountain bike buyers is on battery life, it's important not to overlook the frame. Given the added weight of the battery and electric motor, a tough and sturdy frame is even more important than a traditional bike. A good frame will handle the extra weight without breaking on rough terrain. 

The right model with good frame construction allows for proper weight distribution so that the bike maintains speed. Modern electronic mountain bikes should have a speed of around 30MPH. 

Motor Rating

The motor determines the power performance of your electric mountain bike. The average electric bike motor rating is 250 watts.

Battery Performance

You need to select a bike with good battery life. Imagine how annoying it would be having to drag your heavy electric bike uphill due to battery failure. We recommend choosing a battery that can last at least 15 miles at 20 MPH. 

Style and Design

Some models allow users to switch biking modes. For example, you can change it to electric mode if you want to avoid pedaling for some time. Some come with a foldable design to make them convenient to carry and easy transportation. 

Review of the Best E Mountain Bikes

Electric mountain bikes come with convenient features to make riding fun. However, different brands have unique characteristics to meet different preferences. Here are some options for you.

Another outstanding feature about this bike is the use of disk brakes, which provide sufficient braking to stop immediately, even at full speed. The coolest aspect is that it boasts an anti-skidding tire, which is favorable for difficult terrain.

What is an Electric Mountain Bike and How Does it Work?

An electric bike is one that comes with a motor to help the user along the way with less effort required for pedaling. It works when you switch the motor into action as you pedal. The motor senses the amount of power you put into the pedals and responds proportionally. In other words, the harder you pedal, the more assistance you get from the motor. 

The electric mountain power bike gives you an option to select the type of power you want. For instance, you can switch the power altogether and ride on non-electric mode.

Benefits of Investing in a Quality Electric Mountain Bike

The electric bike has excellent benefits to the user as highlighted below:

Fitness-friendly

An electric bike is a great product to cut back on your monthly gym membership. The more you use an electric bike, the more you gain on the physical fitness aspect. As you pedal in fresh air and sun, you improve your mental and physical health. It is a good device to invest in for your overall well-being. 

Eco-friendliness

The electric mountain bike is a great investment. It produces clean power you can feel good about. Furthermore, you will be on the safe side of the law as the small size is legal in many places that dirt bikes or ATVs aren't. It doesn't produce harmful chemical compounds to pollute the public lands all mountain bikers share and enjoy. While e-bikes still aren’t allowed on a designated non-motorized trail, recent moves by land managers indicate that may change shortly.

Convenience and Comfort

Electric mountain bikes make your journey a comfortable one, regardless of where you are traveling. It becomes more comfortable when you are crashing the slope with some power behind you. Again, such bikes grant the user the ability to enjoy riding in hostile weather conditions such as snow and ice. The bike assists you in going further beyond your outdoor adventures. 

Pros and Cons of Electric Mountain Bikes

Pros

Types of Electric Mountain Bikes

There are three types of electric bikes, as discussed in this section. 

Type 1 E-Bike

Also known as pedal assist. Such a bike requires the rider to pedal to use the motor. It behaves like a traditional mountain bike except that the attached motor senses how you pedal and comes into action to assist in your peddling efforts. This model may have a throttle or not. It has no age limit and can attain a maximum speed of 20 MPH.

Type 2 E-Bike

It is a throttle-only bike. The throttle controls the motor. The user does not have to pedal to benefit from its motor. You only have to crank the throttle to get the power. It allows one to accelerate when negotiating a corner, thereby increasing traction. When you pedal-less, you run out of battery power.

Type 3 E-Bike

You can operate at a maximum speed of 28 MPH when using this option. However, a helmet is a must.

It is the right option for the user who likes hassle-free commuting. The user must be over 17 years old to use it. It is noteworthy that a license is not required. 

E-MTB Comparisons

It can be hard to decide with so many variations out there. Here are some comparisons to help.

Hardtail vs Full Suspension

A full-suspension bike is your best choice if you are ready to dig deeper into your pocket. It is a suitable option to ride over rough terrain with roots and rocks. The rear and front suspension provide a smoother ride with good traction. 

Such bikes have excellent shock absorption. It reduces fatigue and allows one to ride faster. By absorbing more shock, you can ride at a faster speed over technical sections of the trail. 

The hardtail mountain bike is suitable for you if you are running on a budget. It allows the user to apply it over smooth trails to get a fast and fun-filling riding. The front suspension can soak moderate bumps to increase comfort. 

The hardtail mountain bike requires little maintenance since it has fewer moving parts, which are less costly. However, it also requires some essential maintenance to keep it in sound form. 

This bike weighs less than its full suspension counterpart. Less weight is advantageous when you are covering long distances or climbing. 

E MTB vs Road Bike

Manufacturers design road bikes for comfortable riding on pavement. The road bikes have drop handlebars and skinny tires and are preferable for on-road racing. They can be uncomfortable when used on unpaved trails. Typically, they are lighter than E MTB bikes. 

Mountain bikes are the best alternative for riding on rough off-road trails. They use either upright or flat handlebars. 

Some mountain bikes have shock absorbers for increased comfort. They are suitable for commuting or touring.
