The Ultimate Electric Dirt Bike Speed Machines

Electric dirt bikes are becoming increasingly popular, with some models rivalling the power of supercross gas bikes. The Stark Varg is widely considered the fastest electric dirt bike, and it's now street-legal in the US, EU, Australia, New Zealand and Canada. However, it's expensive, with a price tag of around $10,000. Other fast electric dirt bikes include the 2025 E Ride Pro SR, the KTM Freeride, the Mag Wheels 23KW Big Boy e-bike, and the Ninja 23.

Stark Varg: the world's fastest electric dirt bike

The Stark Varg is a powerful electric dirt bike that has been hailed as the world's fastest. With double the power of a regular gas dirt bike, the Stark Varg is a sustainable transportation option that doesn't compromise on performance.

The bike's innovative design incorporates cylindrical cells that function as part of the structure, reducing weight and improving overall efficiency. This unique approach to battery technology has caught the attention of the electric motorcycle community, with some users praising the increased reliability and reduced production costs associated with cylindrical cells.

However, heat management remains a challenge for electric motorcycle manufacturers, and the Stark Varg is no exception. While Energica's previous-generation battery packs had no issues with heat, their current-gen packs have struggled with back-to-back ride and charge sessions, leading to concerns about heat dissipation.

Despite this, the Stark Varg represents a significant step forward in the world of electric dirt bikes, offering an exciting glimpse into the future of sustainable transportation. With its impressive performance and forward-thinking design, the Stark Varg is leading the way for electric motorcycles, showcasing the potential for environmentally conscious options that don't sacrifice speed or power.

Cylindrical cells: a potential solution to heat issues

The Stark Varg is considered the world's fastest electric dirt bike. However, Energica, the manufacturer of the Varg, has faced heat issues with its current-gen battery packs. Cylindrical cells could be a potential solution to this problem.

Cylindrical cells have several advantages over other battery types. Firstly, they can be integrated into the structure of the bike, reducing weight and saving space. This is particularly important for dirt bikes, which need to be lightweight and manoeuvrable. Cylindrical cells also offer better reliability and cheaper production costs.

Most importantly for the Varg, cylindrical cells offer better heat reduction. Heat issues are a common problem for electric motorcycle manufacturers, and cylindrical cells could help to address this. By reducing heat, cylindrical cells can improve the performance and longevity of the battery packs.

There are some potential pitfalls to using cylindrical cells, however. For example, it may be difficult to manage the fit of the cells into the bike's structure while maintaining the necessary clearance for cooling. Additionally, the density of cylindrical cells may be lower than that of other battery types, which could impact the range of the bike.

Despite these potential challenges, cylindrical cells offer a promising solution to the heat issues faced by the Stark Varg and other electric motorcycles. By improving heat reduction, cylindrical cells can help to enhance the performance, reliability, and longevity of these vehicles.

Energica's previous gen packs: no heat issues

The Stark Varg is the world's fastest electric dirt bike. It has double the power of a regular gas dirt bike and a battery range of around six hours.

Energica's previous gen packs have no heat issues. This is in contrast to the current-gen packs, which do have heat issues with back-to-back ride and charge sessions. It is suspected that this is because Energica assumes that most of their customers will do a ride that takes up most of the battery, stop for lunch, and then continue riding. This gives the battery time to cool down.

Energica is one of the two most popular electric motorcycle manufacturers, along with Zero. Many electric motorcycle manufacturers have run into issues with heat. This is a significant problem as it can affect the performance and range of the bike.

Cylindrical cells may be a way to help fix heat issues in electric dirt bikes. They have the advantage of better heat reduction, as well as better reliability and cheaper production costs. However, there are also potential pitfalls to using cylindrical cells. It is not possible to know any density numbers for this hypothetical situation, but pairing it with the 4680 cells Panasonic is piloting may be a solution.

Zero and Energica: two popular electric motorcycle manufacturers with heat issues

The Stark Varg is considered the world's fastest electric dirt bike. However, many electric motorcycle manufacturers have run into issues with heat, especially the two most popular: Zero and Energica. Energica's previous-gen packs had no issues with heat, but the current-gen packs do have heat issues with back-to-back ride and charge sessions. This is likely due to Energica assuming that most of their customers would do a ride that takes up most of the battery, stop for a break, and then continue riding. Zero and Energica are two of the most popular electric motorcycle manufacturers, and their heat issues are a concern for riders. It is important for electric motorcycle manufacturers to address heat issues to ensure the safety and performance of their bikes.

Panasonic's 4680 cells: a possible pairing with cylindrical cells

The Stark Varg is considered the world's fastest electric dirt bike.

Panasonic has unveiled a prototype of a new, high-capacity cylindrical lithium-ion battery: the 4680-type (a diameter of 46 mm and a height of 80 mm). The innovation of this battery is that the cells form part of the automobile's design, removing weight as a result of the pack no longer needing to insulate the cells from the movement of the automobile. The 4680 battery also features a 'tabless' design, which ditches the standard tab connectors discovered on cylindrical cells, changing them with simplified connectors which can be simpler to fabricate and higher for EV purposes.

The 4680 cells could be paired with cylindrical cells to help fix heat issues in electric motorcycles. Cylindrical cells can be fitted into a bike that functions as part of the structure, so they take up less space and the overall motorcycle weighs less. This could be a possible solution for electric motorcycle manufacturers that have run into issues with heat, such as Zero and Energica.

Panasonic has not yet revealed the chemistry or details on when and where the 4680 battery cells will enter series production. However, they have rescheduled mass production of the 4680-type cylindrical battery cells in order to improve their performance and thus enhance competitiveness.
