Innovative CVT Motor Systems at Eurobike 2026
The Eurobike 2026 event has unveiled significant advancements in electric bicycle driving systems, focusing on integrated solutions over traditional setups. While classic mid-mounted motors continue to rely on external chain systems, innovative concepts like those presented by Avinox and Gobao are working to unify transmission and motor control in a more cohesive system. This year, the spotlight is on continuously variable transmission (CVT) systems, aiming for efficiency and flexibility in gear shifting.
Avinox MG Drivetrain: A Game-Changer
Avinox’s MG Drivetrain was a highlight at Eurobike, showcasing not only a new motor but a complete motor-gear system. With an impressive range of 100% to 520%, this system touts an “infinitely variable gear ratio.” This flexibility positions it as a suitable alternative to traditional 1x systems often used in e-MTBs, offering adaptability in different riding conditions.
An intriguing aspect of the Avinox MG Drivetrain is its performance under load. The system is designed to shift gears in under 0.1 seconds while maintaining torque, a feat that challenges traditional models that require more than a second for gear changes. With various shifting modes available—automatic, manual, and multi-gear—users can customize their riding experience significantly.
Key Features of Avinox MG Drivetrain
- Infinite Gear Ratio: 100% to 520%
- Shifting Modes: Automatic, Manual, and Multi-Gear
- Load Capacity: Can shift under load with up to 300 Nm
- Functions: Includes assist-off gear shift, mechanical motor lock, and integrated speed sensor
- Compatibility: Works with existing Avinox batteries of the M1/M2S platform
- Market Release: Anticipated by year’s end, although not confirmed
Gobao X1 and X1P: High-Performance Motor Systems
In contrast, Gobao’s X series takes the integrated approach further by combining the E-Motor with an electronically controlled CVT within a single housing. The more robust Gobao X1P offers a peak power of 1,500 W and a maximum torque of 150 Nm, while the standard X1 generates 1,200 W and 120 Nm. Both units weigh 3.85 kg, establishing them as lightweight contenders in the e-MTB market.
During initial test rides, the Gobao motor demonstrated substantial power without being excessively rough or noisy. What stands out is the motor’s versatility, offering various shifting modes: manual, cadence-based, and automatic, providing riders with a fulfilling experience tailored to their preferences.
Features of Gobao X1 and X1P
- Power Output: X1 at 120 Nm and X1P at 150 Nm
- Peak Performance: X1 at 1,200 W and X1P at 1,500 W
- Weight: Each unit weighs 3.85 kg
- Shifting Options: Manual, cadence-based, and automatic shifting
- Quick Charging: 10% to 80% in just 20 minutes with a compatible battery
The Appeal of CVT Motorization
The allure of CVT systems lies in a streamlined design with fewer exposed components, thereby reducing the chances of mechanical failures like bent derailleurs. Notably, the separation between motor performance and shifting processes provides an enhanced user experience. This design is particularly beneficial in e-MTBs, where power delivery and gear selection need to be in sync constantly.
However, as impressive as these advancements are, integrating motor and transmission systems remains a complex challenge. Factors such as efficiency, durability, maintenance, and user-friendliness will dictate whether these innovations will thrive outside of trade shows and into real-world applications.
Conclusion
With companies like Avinox and Gobao pushing the boundaries of e-MTB technology, CVT systems represent a bold step into the future of cycling. For enthusiasts and casual riders alike, the question remains: Are CVT motors the logical next step for e-MTBs, or do traditional gear systems still have an edge? Only time and user experience can dictate this outcome.
Stay tuned for more insights and updates from Eurobike 2026 as this innovative technology unfolds.
