How Fast Does An Electric Dirt Bike Go

Electric dirt bikes are one of the motorcycle types that came out in recent years. Unlike the typical dirt bike, it does not require fuel to power an engine. Now, in terms of speed, one question that comes to mind is, “how fast does an electric dirt bike go?”

Typically, electric dirt bikes are said to have top speeds of about 30 mph. However, given technological advancements, there are designs with top speeds beyond this estimate. We will elaborate these in the succeeding sections.

Top Speed of Electric Dirt Bikes

Just like other motorcycles, electric dirt bikes come in different sizes, models, and specifications. This is evident with different electric dirt bike brands emerging in the market.

To compare some of the known models of this vehicle type, tabulated below are some of the best electric dirt bikes in recent years with their respective top speeds, power, and battery charging time.


Dirt Bike Model Motor or Battery Power Top Speed (mph) Charging Time (h)
Zero FX 7.2 kWh 85 1.5
Sur-Ron (Electric X Dirt Bike) 6 kWh 47 3.5
Cake (Kalk OR) 2.6 kWh 56 2
Kuberg (Ranger) 8 kWh 50 2
Razor (Dirt Rocket) 7 Ah 15 12
Tacita (T Race Enduro) 8 kW 47 2.5
KTM (FreeRide E-XC) 18 kW 35 2
Segway x260 5 kW 46.6 4
Bultaco Brinco 2 kW 37.3 3
Stark VARG 6 kWh 71.4 1

If you are a beginner or have a kid interested in electric motorcycles, the Razor electric dirt bike is a suitable model to cater such needs. Its speed ranges from 12 to 22 mph.

Factors Affecting Dirt Bike Speed

The more you explore about electric dirt bikes, the more you realize that there are several factors dictating their top speed, which include the following:

1. Battery condition


Battery condition means a combination of its capacity to store power, its age, and the technology behind the design. When you encounter a fast electric dirt bike, its battery is expected to be new, modern, and with more energy storage than its counterparts.

In addition, a bigger battery capacity also means it will last longer before power runs out during rides. An electric dirt bike at full charge will run at its maximum speed consistently, unlike when it is low on energy.

However, it also implies the need for more charging time when the battery runs out.

Older batteries may also yield lower top speeds compared to new ones.

2. Dirt bike weight


The material of an electric dirt bike may also be a factor in its top speed. It is expected that if two bikes have the same battery capacity but one is heavier, the heavier one requires more power to achieve a faster top speed.

In the same manner, the rider weight may also contribute to diminishing an electric dirt bike’s maximum speed.

3. Aerodynamic design


Considering the amount of drag and air resistances encountered while driving, it is expected that higher electric dirt bike top speeds are achievable if these aspects are minimal and optimized through the electric dirt bike design process.

4. Terrain


Bumpy or sloped terrains can slow a bike down. The former has uneven spots that reduce momentum, while the latter requires you to move against gravity.

Fastest Electric Dirt Bikes in the Market

With emerging technologies on electric dirt bikes, there are indeed models that are considered cream of the crop in this category. Two of the fastest off road ebike are the Zero DS and Stark Varg Alpha. Specifications for them are as follows:


Specifications Zero DS Stark Varg
Top Speed 98 mph 71.4 mph
Horsepower 46 80
Battery Capacity 7.2 kWh 6 kWh
Weight 317 lb 242.5 lb


When someone asks you, “how fast does an electric dirt bike go?”, you may say that it typically ranges from 20-30 mph. However, engineering marvels in the dirt biking world allow development of vehicles that are faster and more efficient.

That being said, the possibilities of advanced electric dirt bikes are endless. Who knows, there may be faster ebike models in the years to come that can be on par with the performance of your typical 2-stroke or 4-stroke vehicles.
