Hubless Motorcycles: The Disruptive Future of Two-Wheeled Mobility

As global transportation accelerates toward electrification, the motorcycle industry is undergoing a radical transformation. Internal combustion engines are being replaced by electric motors — but beyond that, even the drive architecture itself is evolving.

In recent years, the hubless motor (also known as a toroidal motor) has emerged as one of the most futuristic innovations in the electric motorcycle field. Led by pioneers like Verge Motorcycles and Noll, this technology is redefining vehicle mechanics, design aesthetics, and space utilization — offering a glimpse of how two-wheeled mobility could look in the near future.

What Is a Hubless Motor?

Despite its name, a hubless motor doesn’t mean the absence of a motor. Instead, it refers to a drivetrain that eliminates the traditional central axle and integrates the motor around the outer rim of the wheel. Find the more about the electric motorcycle drivetrain.

Unlike conventional in-wheel motors, which enclose the entire motor within the wheel hub, a hubless motor features a hollow-center wheel. The stator is fixed to the swingarm or frame, while the rotor is mounted on the wheel’s outer edge, directly driving the tire. The result is a ring-shaped power unit, often described as a “doughnut motor” due to its hollow geometry.

In essence, the wheel itself becomes the motor. This integration removes the need for axles, gearboxes, or chain drives, simplifying mechanical complexity while maximizing efficiency.

Hubless vs. In-Wheel Motors: The Core Differences

Although both technologies place the motor near the wheel, their engineering philosophies diverge sharply.

Feature Hubless Motor Traditional In-Wheel Motor
Core Structure No central axle; stator fixed to frame; rotor drives rim Motor enclosed within the wheel hub
Space Utilization Hollow center allows integration of brakes, sensors, or batteries Interior filled with motor components, limited space
Integration Level Deeply coupled with chassis or swingarm Modular, easily replaceable unit
Unsprung Weight Still high but can be optimized structurally Significantly increases unsprung mass
Common Use Cases High-end electric motorcycles, concept vehicles E-bikes, low-speed EVs, entry-level e-motorcycles

These structural distinctions lead to tangible differences in performance, handling, maintenance, and design freedom.

Verge Motorcycles: The Pioneer of the Toroidal Drive

Verge's First Hubless Electric Scooter

Founded in Finland in 2024, Verge Motorcycles has become the most recognized brand in the hubless electric motorcycle arena. Within just one year, Verge introduced three models — TS Pro, TS Ultra, and TS California Edition — all built on its proprietary toroidal drive system.

The Verge TS Ultra is particularly impressive: delivering up to 1,200 Nm of motorcycle torque directly to the rear wheel and accelerating from 0–96 km/h in just 2.5 seconds — numbers that rival top-tier supercars.
Its secret lies in the ring motor integrated into the rear wheel’s rim. This design not only frees up the wheel’s center space but also allows direct torque transfer, minimizing energy loss and achieving near-perfect drive efficiency.

At EICMA 2025 (Milan Motorcycle Show), Verge is expected to unveil its first hubless electric scooter — a compact model tailored for urban commuters:

  • Equipped with a 12-inch ring motor offering 2–15 kW power and 80–350 Nm torque;
  • Features a transparent wheel cover design emphasizing its futuristic hollow structure;
  • Seamlessly integrated with Verge’s in-house battery modules and software suite;
  • Positioned at a more affordable price point, aiming to make hubless technology mainstream.

Perhaps most strategically, Verge has announced a platform licensing model, branded as Verge Next, allowing other manufacturers to adopt its toroidal motor technology — potentially accelerating industry-wide adoption.

From Motorcycles to E-Bikes: Expanding the Hubless Horizon

Noll Go Spokeless Electric Bike

The hubless concept is also making its way into electric bicycles. At Eurobike 2025, Swedish startup Noll unveiled its debut model, the Noll Go, showcasing a hubless, spoke-free wheel architecture.
The Noll Go’s wheel integrates dual drive modules and traction control, offering enhanced stability on uneven terrain. Its hollow center serves multiple purposes: it can house storage accessories, an auxiliary battery, or even a cargo rack. Other innovative features include:

  • Built-in LED turn signals within the wheel;
  • A touch display mounted on the handlebar;
  • USB-C charging and reverse power output for mobile devices.

Priced at €6,995, the Noll Go may not be cheap, but its bold engineering and futuristic design have sparked widespread attention across the e-mobility industry.

The Technical Advantages of Hubless Motor

The hubless motor’s appeal stems from a combination of engineering efficiency and design freedom.

  • Maximized Space Utilization: The hollow hub provides room for braking components, sensors, or small batteries — a game-changer for compact or modular vehicle designs. Explore more about ebike sensors.
  • High Power Transfer Efficiency: With no chain, belt, or axle, torque flows directly from motor to tire, reducing mechanical loss and improving regenerative braking potential.
  • Design Flexibility and Aesthetics: The absence of a central hub allows radical wheel designs — transparent, skeletal, or aerodynamic — blending function with futuristic form.
  • Platform Scalability: Hubless drive systems can be standardized across multiple vehicle types, lowering R&D costs and shortening time-to-market cycles.

The Challenges of Hubless Technology

Despite its promise, hubless technology still faces several engineering hurdles:

  • High Unsprung Mass: Integrating the motor into the wheel increases unsprung weight, affecting handling and ride comfort — especially at high speeds or on rough roads.
  • Thermal and Sealing Complexity: The confined rim area makes heat dissipation difficult. The motor must also be sealed against water, dust, and road debris — demanding robust materials and precision manufacturing.
  • High Manufacturing and Maintenance Costs: The integrated design is expensive to produce and challenging to repair. In many cases, component failure requires replacing the entire wheel module.
  • Brake System Integration: Combining mechanical and electronic braking within a compact rim environment is complex. Electric braking alone isn’t sufficient for safety, and traditional vacuum-assisted systems are unsuitable for EVs.

The Road Ahead: From Concept to Mainstream

Currently, hubless motors are primarily found in premium electric motorcycles, concept vehicles, and special-purpose machines. However, compared to cars, two-wheelers experience less impact from unsprung mass — giving the technology a more favorable testing ground.

Future advancements in lightweight materials (carbon fiber, high-strength aluminum), thermal management (liquid cooling, phase-change materials), and active suspension algorithms are expected to mitigate many of today’s limitations.

The success of Verge and Noll shows that consumers are increasingly open to products that combine technological innovation with aesthetic expression.

Ultimately, the hubless motor represents more than just a new drivetrain — it symbolizes a paradigm shift in mobility engineering. It transforms the wheel from a passive rotating element into an intelligent power module, blurring the line between mechanics and electronics.

Conclusion

Hubless electric motorcycles embody the next frontier in personal transportation — compact, efficient, and visually striking. While the technology still faces cost and durability challenges, its long-term potential is undeniable.

As innovation in materials, software, and manufacturing accelerates, hubless drive systems could soon become a realistic option for mainstream two-wheelers, offering cleaner, quieter, and smarter mobility solutions.

In the near future, hubless motorcycles may not only reshape how we move but also how we imagine the machine itself — turning the wheel into the beating heart of the electric revolution.
