Materials in Electric Scooters
Aluminum
One of the primary materials used in the manufacturing process of electric scooters is aluminum. Renowned for its lightweight and corrosion-resistant properties, aluminum plays a vital role in enhancing the durability and longevity of electric scooter frames, decks, fenders, stems, and handlebars.
What makes aluminum such a popular choice? Its high strength-to-weight ratio is one of the key factors. This means that electric scooters made with aluminum can achieve higher speeds while conserving energy. The lightweight nature of aluminum allows for easy maneuverability, making it an ideal material for urban commuting.
Most aluminum alloys won’t crack or rust, and they are mostly recyclable. But keep in mind that not all aluminum is equal. The highest grade aluminum alloys are suitable for airplane construction and thus are labeled aviation grade or aircraft grade aluminum. Apollo’s electric scooter frames are made from durable, recyclable 6061 aircraft grade aluminum, or from nearly indestructible forged aluminum in the frame of the Apollo Ghost.
Carbon Fiber
Carbon fiber has emerged as another sustainable and high-performance material that is gaining popularity among electric scooter manufacturers. Used in bike frames and components for decades for its exceptional strength and low weight, carbon fiber offers numerous advantages for scooter design.
One of the significant benefits of carbon fiber is its ability to reduce the overall weight of electric scooters. By incorporating carbon fiber components, manufacturers can significantly reduce the scooter's weight without compromising on structural integrity. This reduction in weight not only improves battery efficiency but also enhances the scooter's maneuverability. Lightweight commuter scooters like the Unagi Model One use carbon fiber in their design.
Carbon fiber's strength allows for the construction of sleek and aerodynamic scooter frames. This not only enhances the scooter's aesthetic appeal but also contributes to improved performance. The lightweight and rigid nature of carbon fiber ensures that the scooter can withstand the rigors of daily use without sacrificing speed or stability.
Carbon fiber is, unfortunately, subject to cracking under conditions of extreme stress, and it cannot be repaired. On the other hand, the flexibility of carbon fiber makes it ideal for custom or bespoke fabrication since carbon fiber designs can be extruded from 3D printers.
Other Materials
While aluminum and carbon fiber are undoubtedly popular choices, some other materials that can appear in mark in electric scooter design include magnesium and titanium. Magnesium alloys are known for their lightweight nature and impressive mechanical properties, making them an attractive option for scooter construction.
Titanium is well-known for corrosion resistance, exceptional strength, long-term durability, light weight, and stiffness. This expensive metal is typically only used in high end racing scooters.
Electric scooters also use some less-than-sustainable materials in their construction, such as rubber, plastics, and rare earth metals, but the bulk of an electric scooter’s construction is taken up by its frame and battery.
Lithium Ion Battery Construction
When it comes to electric scooters, the focus on sustainable materials is crucial for the scooter's structure. However, it is equally important to consider the battery construction. Lithium-ion batteries have emerged as the standard choice for electric scooters due to their superior energy storage capabilities and longer lifespan compared to other battery types.
First, lithium-ion batteries are known for their lightweight and compact design. This characteristic is particularly advantageous for electric scooters as it allows for a more streamlined and efficient overall design. Riders can enjoy a sleek and agile scooter without compromising on performance. Electric scooters like Apollo’s Pro 2023 use high-quality Samsung batteries that last far longer and provide more energy efficiency than comparable generic cells.
Another key advantage of lithium-ion batteries is their high energy density. This means that they can store a significant amount of energy in a relatively small and lightweight package. As a result, electric scooters equipped with lithium-ion batteries can travel longer distances on a single charge compared to scooters powered by other battery types. This enhanced range capability has been a game-changer, providing riders with the freedom to explore more without worrying about running out of power.
Energy Density
Advancements in lithium-ion battery technology have led to reduced charge times. In the past, charging an electric scooter could be a time-consuming process, limiting its practicality for everyday use. However, with more energy-dense 21700 cells and more efficient chargers, lithium-ion batteries can be charged more quickly, making electric scooters more convenient and accessible for riders.
The construction of lithium-ion batteries plays a vital role in the overall performance and practicality of electric scooters. Their lightweight design, high energy density, reduced charge times, and longer lifespan make them the ideal choice for powering these eco-friendly vehicles. As the technology continues to advance, we can expect even more innovations in lithium-ion battery construction, further enhancing the efficiency and sustainability of electric scooters.
Renewable Materials for Electric Scooter Design and Construction
Beyond the conventional materials like aluminum and carbon fiber, researchers and manufacturers are continuously exploring innovative renewable materials for electric scooter construction. This drive to find alternatives stems from the growing concern over resource depletion and the need to mitigate the environmental impact of manufacturing.
For instance, bioplastics derived from renewable sources, such as cornstarch, sugar cane, or vegetable oil, are being tested as potential replacements for traditional plastics. These biodegradable materials offer similar strength and durability properties but have a significantly reduced carbon footprint and can decompose naturally.

Furthermore, natural fibers like hemp, bamboo, and flax are also being incorporated into electric scooter prototype designs, offering sustainable and renewable alternatives to synthetic materials. These natural fibers not only reduce the reliance on fossil fuels but also provide a lightweight solution that helps improve overall energy efficiency.
The Cost of Sustainable Electric Scooter Materials
While renewable materials for electric scooter construction offer numerous benefits, one significant challenge manufacturers face is the cost associated with these alternatives. Compared to conventional materials, sustainable options often come at a higher price due to limited availability, production limitations, and research and development expenses.

However, as demand for sustainable electric scooters rises and technology advances, it is expected that the cost of these materials will decrease over time. Governments and organizations are also providing incentives and funding to encourage the adoption of sustainable manufacturing practices, which could further drive down costs and make electric scooters more affordable for the masses.
Reducing Carbon Footprint Through Sustainable Electric Scooter Design
Electric scooters offer a significant opportunity to reduce the carbon footprint associated with urban commuting. By shifting from gas-powered vehicles to electric scooters, individuals can actively contribute to a cleaner and greener environment. However, it is equally important to ensure that these vehicles are built sustainably to maximize their environmental benefits.

By incorporating sustainable materials throughout a low-impact electric scooter manufacturing process and considering the entire lifecycle of electric scooters, manufacturers can reduce emissions, conserve resources, and lessen their ecological impact. The ongoing research and development in this field will lead to further innovation and advancements, making sustainable electric scooters an even more attractive and viable option for environmentally conscious consumers.
Apollo is committed to using the most environmentally sustainable materials available and has created over 150 custom parts for their electric scooters to meet the demand for their vehicles with the full oversight of their design and production team. This means much less waste and a much smaller supply chain carbon footprint than other manufacturers – and it means more reliable, durable, and built-to-last electric scooters.
