Serial 1

Serial 1 was created to address the growing need for clean, efficient urban transportation by offering an e-bike that’s accessible, stylish, and intuitive. The challenge was to combine high-end performance with low-maintenance design while retaining the soul of Harley-Davidson’s iconic engineering. Key obstacles included achieving a lightweight frame, ensuring global compliance with strict safety standards, and integrating advanced features like automatic gear shifting and app connectivity without overwhelming the rider. The result is a premium e-bike that feels effortless to ride, appeals to a wide demographic, and exceeds expectations for both functionality and design—redefining what modern e-mobility can be.

The Serial 1 design solution blends Harley-Davidson’s legacy with cutting-edge e-bike technology to create a seamless, rider-focused experience. Key breakthroughs included integrating the Brose S MAG mid-drive motor for natural-feeling assistance, the Gates Carbon Belt Drive for low maintenance, and Enviolo's automatic shifting hub. Early prototypes revealed challenges with weight distribution and intuitive control, leading to refined frame geometry and improved UX. A major milestone was adapting the design for global safety standards without compromising performance. By prioritising simplicity, safety, and style, Serial 1 delivered an elegant solution to modern mobility—making e-biking accessible, enjoyable, and sustainable for a wider audience.

Serial 1 e-bikes have made a strong impact by redefining urban mobility with a premium, sustainable, and approachable product. Commercially, the brand has attracted both new and experienced riders, strengthening market presence and customer loyalty. Environmentally, it promotes clean transportation and uses durable, low-maintenance components to reduce waste. Socially, it encourages healthier lifestyles and greater transport equity by making high-quality e-bikes accessible to a wider audience. With U.S. assembly under new ownership, Serial 1 also supports local manufacturing and shortens supply chains—amplifying its positive economic and environmental impact.

Serial 1 e-bikes are engineered with standout features that prioritise simplicity, performance, and user experience. At the core is the Brose S MAG mid-drive motor, delivering smooth, natural power with four ride modes. The Gates Carbon Belt Drive replaces a traditional chain for a maintenance-free, grease-free ride, while the Enviolo AUTOMATiQ CVT hub offers seamless, automatic gear shifting based on cadence and terrain. A fully integrated battery and internal cable routing preserve clean lines and protect components. Built-in LED lighting and reflective details enhance rider visibility and safety. The frame geometry is optimised for comfort and control, and models are available in step-through and diamond frame designs to suit a wide range of riders. Each bike includes app connectivity for real-time ride stats, GPS tracking, and system updates. The design also considers regional compliance—such as the Australian market’s adaptation of frame components for local safety certification—without altering the iconic aesthetic. These key features, along with durable construction and low-maintenance systems, create a premium e-bike that’s as stylish as it is functional, appealing to both urban commuters and recreational riders.
