Things to Consider

Here are a few key things to consider when finding the electric mountain bike under $4,000 that’s right for you.

Type of Tires

On this list, we see a bike with a thin tire and one with fat tires, plus two with regular sizes. Each comes with its own realm of pros and cons. For example, thinner may be more lightweight but won’t be able to handle rugged terrains.

Battery Voltage

You want to make sure you’re buying a battery with voltage you need. That way, you don’t end up without a charge on the side of the mountain. That said, pay attention to the battery voltage and how long the battery can sustain this charge.


A strong motor is best for those planning to go on excursions in different terrains and scales. A powerful motor will be able to handle uphill and downhill with ease whether you’re on sandy, snowy, or rocky terrain.


Consider the overall MPH of the pedal-assist. This is critical. If you want your bike to lend you a helping hand with lots of speed, then you need to find a bike that can take on the heat.


Want extra features for your convenience? Everyone has a personal preference when it comes to features they want or need, such as a backlit LED or an intelligent eMTB. Pay attention to what each bike has to offer to find the one that’s right for you.


Last but not least, consider the price. Yes, it’s clear that you’re here to stick to a budget of under $4,000, but that doesn’t mean you want to get as close to $4,000 as possible. There are a lot of options on this list that are under the $2,000 range, which means almost every budget can find what they’re looking for.

Final Thoughts

Having an electric motor bike can open the door to new experiences, and you don’t have to spend an arm and a leg. These four electric mountain bikes under $4,000 are crafted to satisfy all of your electric mountain bike cravings.
