Electric motorcycles are more efficient than electric cars, with two-wheeled electric motorcycles consuming less battery capacity per kilometre travelled. The total battery capacity of an electric motorcycle is measured in kilowatt-hours (kWh), which indicates how much electricity can be stored in the battery. The Stark VARG electric dirt bike, for example, has a 6 kWh battery, while the Energica Ego supersport race bike has a 21.5 kWh battery. The rider's weight and average running speed positively influence electricity consumption, while deceleration time negatively affects it. Eco-driving behaviours, such as maintaining an average running speed of 12.7% lower than the non-eco-driving cycle, can reduce electricity consumption and CO2 emissions.

What You'll Learn
Kilowatt-hours (kWh) are a measure of stored energy
For instance, the Stark VARG electric dirt bike has a 6 kW/h battery, while the Energica Ego supersport race bike has a 21.5 kWh battery. The former is designed to be light and nimble, with a shorter range, whereas the latter has a higher power output and a longer range of around 220 km.
The range of an electric motorcycle depends on several factors, including brand, size, energy output, and road conditions. Generally, electric motorcycles can achieve a range of 50-110 km on a single charge, with some models, like the Tromox Mino, capable of exceeding 100 km.
When calculating the power of an electric motorcycle, we use kilowatts (kW) as the unit of measurement. A higher kW value indicates greater power and faster acceleration. Similarly, the efficiency of an electric motorcycle is measured in watt-hours (wh), with lower values indicating higher efficiency. For instance, most full-speed electric motorcycles have an efficiency of 30-60 wh/km, making them more efficient than electric cars, which typically have efficiency values of 130-250 wh/km.
By understanding the relationship between kWh, kW, and wh, we can make informed choices about electric motorcycle performance, range, and efficiency, ensuring we select the most suitable vehicle for our needs.

Battery capacity is measured in kWh
The total battery capacity of an electric motorcycle is measured in kilowatt-hours (kWh). This unit of measurement tells you how much electricity can be stored in the battery. The higher the kWh, the more electricity the battery can store and the longer the range of the motorcycle.
For example, an electric motorcycle with a 10 kWh battery, or 10,000 watt hours, can travel 333.3 km or 208 miles. This is calculated by dividing the total capacity of the vehicle by its efficiency. In this case, the electric motorcycle has an efficiency of 30 watt hours per km (wh/km), so 10,000 wh divided by 30 wh/km gives you a total range of 333.3 km.
The kWh measurement is also used to determine the efficiency of electric motorcycles in comparison to electric cars. For instance, a full-speed electric motorcycle may have an efficiency of 30 wh/km to 60 wh/km, while a four-wheel electric car typically ranges from 130 wh/km to 250 wh/km. This means that electric motorcycles are more efficient than electric cars in terms of battery capacity consumed per km travelled.
It's important to note that the kWh measurement represents stored energy, not the rate at which electricity is consumed. Different electric motorcycles will have different kWh capacities depending on their intended use. For example, a lightweight electric dirt bike designed for short, explosive bursts of speed may have a smaller battery capacity than a supersport race bike designed for higher power output over longer distances.

Electric motorcycles are more efficient than electric cars
Secondly, electric motorcycles offer better mileage than electric cars. Due to their smaller size, motorcycles can achieve greater energy efficiency, and they are not subject to the same emission standards as cars, further enhancing their environmental benefits. The higher mileage of electric motorcycles also makes them a more cost-effective option, as they require less energy to charge and can take advantage of the increasing number of electric vehicle charging stations.
Additionally, electric motorcycles provide a unique driving experience that cannot be replicated in a car. They offer riders the freedom to enjoy nature and explore their surroundings, whether it's a scenic drive or a commute in a crowded city. The growing community of motorcycle riders also provides opportunities for social connections and building new friendships.
Furthermore, electric motorcycles are generally cheaper than electric cars, even when considering rebates and incentives for purchasing electric vehicles. The lower cost of maintenance for motorcycles makes them a more economical choice, especially for those looking for an affordable and environmentally conscious mode of transportation.
While range may be a concern for some when considering electric motorcycles, the rapid development of electric vehicle charging infrastructure is bridging the gap between motorcycles and cars in this respect. Overall, electric motorcycles offer a combination of efficiency, environmental benefits, cost-effectiveness, and a unique driving experience that makes them a compelling alternative to electric cars.

Solar power can be used to charge electric motorcycles
The average home solar system in Australia, for example, is an 8kW system that generates around 32kWh of power per day. After accounting for the average daily power usage of an Australian household (approximately 19kWh), there is typically an extra 12kWh of solar power that can be used to charge an electric vehicle. This is particularly relevant for those with irregular working hours who may have more opportunities to charge their vehicles during daylight hours.
The efficiency of solar charging for electric motorcycles depends on various factors, including the size of the solar panels, the output of power, and the battery capacity of the motorcycle. Smaller electric motorcycles, such as the Stark VARG electric dirt bike, have lower battery capacities, requiring less solar power to charge. On the other hand, the Energica Ego supersport race bike has a larger battery capacity of 21.5 kWh, which demands more solar power.
Additionally, the range of the motorcycle, terrain, riding style, and weather conditions also play a role in determining the effectiveness of solar charging. Investing in high-quality solar panels with photovoltaic cells can improve the efficiency of solar-powered electric motorcycles, even during unfavourable weather conditions.
While portable solar panels may not provide sufficient power for electric motorcycles, home solar systems with fixed panels can be a viable option for charging. With strategic charging, such as charging the motorcycle on full sunny days at home during the weekend, it is possible to store enough solar-generated battery capacity for multiple days of commuting.

Higher kilowatts mean more power
Kilowatts are a measure of power, and kilowatt-hours (kWh) are a measure of energy. The total battery capacity of an electric vehicle (EV) is measured in kWh, indicating how much electricity the battery can store. When it comes to electric motorcycles, higher kilowatts indeed mean more power.
The Stark VARG electric dirt bike, for example, has a 6 kW/h battery that can output 45 kW of power. In contrast, the Energica Ego supersport race bike has a 21.5 kWh battery and can deliver up to 126 kW of power. The Energica Ego's larger battery capacity and higher kilowatts translate into greater power output, showcasing that higher kilowatts mean more power.
The relationship between kilowatts and power is also evident in the example provided by Australian Electric Motor Co. They mention that most home EV charging cables draw about 2.5 kW from the power supply, while household solar systems are typically around 8 kW. This means that during periods of strong sunlight, your EV charging may not utilize all the energy produced by your solar panels.
To further illustrate the concept, let's consider an electric motorcycle with a 10 kWh battery, which equates to 10,000 watt-hours. By dividing this capacity by the efficiency of the motorcycle, we can estimate its range. For instance, if the motorcycle has an efficiency of 30 watt-hours per kilometre (wh/km), we divide 10,000 wh by 30 wh/km, resulting in a total range of 333.3 kilometres or 208 miles.
In summary, when discussing electric motorcycles, higher kilowatts directly translate to increased power output. This relationship between kilowatts and power is fundamental in understanding the performance capabilities of electric vehicles, and it plays a crucial role in calculating their efficiency and range.
