At the 2025 Consumer Electronics Show (CES) in Las Vegas, Donut Lab, a startup focused on revolutionizing in-wheel drive platforms, unveiled a groundbreaking electric hub motor that delivers 630kw (845hp) while weighing just 40kg (88lbs).
This impressive power-to-weight ratio illustrates the advancements in electric motor technology, offering a compact yet potent solution for various applications.
The Donut Motor shares design principles with the hubless-rear-wheel motor used in Verge Motorcycles’ TS series, which we'll explore later. This design not only provides a futuristic aesthetic but is also lighter, more compact, offers higher efficiency, less maintenance, and produces far less heat—the killer of electric motors. All of which will greatly contribute to an EV's performance and handling.
Donut Motor Specs
The motorcycle iteration of the Donut Motor is designed as a 17-inch wheel hub, offering impressive up-front specifications.
150kw
1200nm
21kg
The motor's small size combined with its powerful performance makes it ideal for various applications but especially for e-moto, where weight and available space are at a premium.
Donut Lab's ambitions go beyond just motors; they are developing a complete drivetrain. By building their own bespoke motor, battery, 'brain,' and software as an integrated system, Donut Lab aims to streamline electric powertrains across various industries. This approach offers scalability and reduces research and development costs for manufacturers by providing a robust, ready-to-implement solution. The company has ambitious goals and their website showcases five motor versions, each designated for specific purposes such as Drone, Motorcycle, Scooter, Automotive, and Semi-Truck.
The Brain
The Brain,' as it's called, is the control unit that facilitates seamless communication among all Donut Lab drivetrain components - It functions similarly to the controller in your e-motorcycle. However, The Brain offers advanced AI technology designed to integrate effortlessly with both existing and yet to be developed systems. It includes built-in hardware expansion capabilities, providing a strong foundation for future applications and according to the companies press, is a "universal solution for all EVs."
Verge Motorcycles
Verge Motorcycles, a Finnish startup, introduced the TS model featuring their hubless rear wheel motor that doubles as the rear brake.
The TS series includes the TS Pro, with approximately 136.8 horsepower and a staggering 999.9nm of torque, enabling acceleration from 0 to 60mph in under four seconds. Additionally, the TS Pro offers a range of up to 180 miles in urban settings.
Building on the success of the TS Pro, Verge introduced the TS Ultra at CES 2024. The TS Ultra features advanced technologies, including multiple cameras, radar, and an AI-powered system to enhance rider safety.
Final Thoughts
Donut Lab's cutting-edge motor represents a significant leap forward in the industry. Expanding on Verge's technology, Donut Lab delivers unmatched power and efficiency in a small package. By concentrating on creating a comprehensive drivetrain system, Donut Lab could transform multiple sectors. Their dedication to merging advanced AI-compatible technology with scalable solutions highlights their future vision for electric vehicles. It's evident that Donut Lab is at the forefront of the electric drivetrain field. I can't wait to experience these motors first hand and see them on the roads sooner rather than later.
