What Is the Heritage Spirit Scrambler and What Makes It Unique?

Based near Lake Annecy in the French Alps, Ateliers Héritagebike produces motorcycles in small, carefully crafted series. Their philosophy blends French manufacturing, European sourcing, and refined craftsmanship with sustainable electric mobility.

The Heritage Spirit Scrambler is designed as a modern interpretation of classic scrambler culture with upright proportions, minimalist lines, authentic wire-spoke wheels, combined with a fully electric drivetrain. The challenge was to preserve the emotional appeal of a vintage motorcycle while integrating advanced electric technology in a way that feels natural and invisible.

What Challenges Arise When Integrating an In-Wheel Motor into a Retro Motorcycle?

Integrating electric propulsion into a design-led motorcycle presents several engineering trade-offs. Traditional central motor with transmission appears bulky mounting all components: motor and motor controller and mechanical transmission. It increases  system complexity and disrupting clean frame lines. Selecting GEM in-wheel drive with integrated motor controller together with lassic wire-spoke rims integrate seamlessly into  modern electric propulsion systems.

For a brand where aesthetics define identity, any visible technical compromise would weaken the concept. The drivetrain had to deliver performance, reliability, and structural precision, all while remaining visually coherent with the scrambler’s heritage styling.

How Did GEM Motors Customise the In-Wheel Drive for This Motorcycle?

Rather than adapting a standard product, GEM Motors engineered the customized drive system around the motorcycle’s geometry and design intent.

The motor controller was integrated directly into the hub motor housing, eliminating separate electronic boxes and significantly reducing wiring complexity. This preserved the clean, uncluttered appearance of the frame.

A dedicated double-side mounting configuration was developed to match the rear fork structure, ensuring mechanical stability and precise alignment under load.

The defining innovation is the custom-machined spoke flange integrated directly into the motor housing. This allowed a traditional wire-spoke rim to be laced directly onto the in-wheel drive, maintaining authentic scrambler aesthetics without adapters or visual compromise.

What Are the Performance and Reliability Benefits of an Integrated In-Wheel Drive?

Beyond design integration, the architecture offers clear functional advantages.  By eliminating chains and external transmission components, the drivetrain becomes mechanically simpler and requires less maintenance. Fewer moving parts reduce wear over time. Direct drive ensures smooth torque delivery and immediate response, improving riding feel in both urban and touring conditions.

Integrating the controller inside the motor also reduces potential failure points, increasing overall system robustness and long-term reliability.

Why Is This Project Important for Premium Electric Motorcycles?

The Heritage Spirit Scrambler demonstrates that electric propulsion does not have to conflict with classic motorcycle design. When engineering begins with respect for aesthetics and structural integration, advanced technology can enhance heritage styling.

For GEM Motors, the project highlights the flexibility of its in-wheel drive platform in demanding, design-focused applications. For Ateliers Héritagebike, it confirms that sustainability, craftsmanship, and innovation can coexist within a premium electric motorcycle.

Both companies are continuing discussions around future models and serial production development, building on the technical and creative foundation established with this project.

“This project perfectly reflects our philosophy at GEM Motors — technology must adapt to the vehicle’s identity, not the other way around. With Héritagebike, the challenge was not only performance, but preserving authenticity. By integrating the controller directly into the motor and developing a custom spoke flange, we created a solution that respects classic motorcycle design while delivering modern electric efficiency. That balance between heritage and innovation is where we believe the future of premium electric mobility lies,” stated Simon Mandelj, CEO and Founder of GEM Motors.
