Gobao X1P Gearbox Motor: A Potential Game-Changer for eMTB Drive Systems

The traditional derailleur system has long been a staple in cycling. Even today, eMTBs boasting up to 150 Nm of torque and peak power exceeding 1,200 watts still utilize a similar setup to what was established decades ago: a front motor paired with a rear cassette. However, this norm may soon be challenged.

At EUROBIKE 2026, Gobao unveiled the X1P, an impressive new drive system that redefines how eMTBs operate. Rather than treating the motor, shifting mechanism, and drivetrain as distinct entities, this Chinese manufacturer has integrated them into a cohesive unit. The outcome is an E-CVT drivetrain featuring an integrated gearbox, automatic gear ratio adjustment, a belt drive, and rapid charging capabilities that could render existing systems from brands like Specialized, Avinox, or Bosch obsolete.

What Makes the Gobao X1P Stand Out?

Central to this innovative system is the Gobao X1P, which weighs in at a mere 3.8 kg. This motor-gearbox assembly combines propulsion and shifting functions within a single housing, delivering up to 150 Nm of torque and a peak power of 1,500 watts, as claimed by Gobao. Future iterations may reduce the weight to an impressive 3.5 kg. Additionally, the system boasts a continuously variable gear range of up to 500%, with potential for expansion to 600%.

In contrast to traditional drivetrains, the X1P eliminates fixed gears. Instead, its electronics continuously modify the gear ratio based on cadence, power output, and terrain. For riders who prefer the sensation of shifting, simulated virtual gears can be activated. An intriguing feature tested on the Hepha Urban X is the motor's ability to enable controlled regeneration, gently decelerating the bike when pedaling stops. Backpedaling can enhance this braking effect, providing noticeable benefits, especially during lengthy descents. However, for a truly seamless riding experience, further refinement is needed in specific scenarios like cornering.

Understanding E-CVT Systems

E-CVT, or Electronic Continuously Variable Transmission, merges a motor with a continuously variable gearbox into one unit. This system allows for continuous and nearly imperceptible gear ratio adjustments instead of shifting between fixed gears. The aim is to maintain optimal cadence, whether climbing steep hills, navigating technical ascents, or sprinting on flat terrain. Riders experience an almost infinite number of available gears, with many systems offering automatic shifting to manage gear changes.

In models like the Owuru Gearbox, Avinox MG, and Gobao X1P, two electric motors work within a planetary gearbox. One motor adjusts the gear ratio and manages the ease of pedaling, while the other regulates motor assistance. Together, they ensure that the gear ratio and drive power are continuously optimized for the riding conditions.

Critiques of E-CVT systems tend to focus on electronic calibration, potential efficiency losses, and the characteristics of throttle response and power delivery.

Initial Riding Experience with the Gobao X1P

Test rides of the X1P at EUROBIKE in Frankfurt showcased a remarkably polished system, despite it not being a final production model.

The most notable aspect is the immediate and well-defined power delivery. Even at lower cadences, ample torque is available, allowing the bike to accelerate rapidly yet smoothly up to the 25 km/h assistance limit. With no gear shifts, power delivery remains consistent and exceptionally fluid throughout the ride. Starting off is also straightforward and clearly defined.

Even more impressive is the noise level. While many gearbox systems produce noticeable sounds under load, the Gobao drive operates with surprising quietness. Only at cadences above approximately 100 rpm does a subtle electric whir become audible. Compared to existing gearbox systems, the X1P already feels remarkably close to being ready for market. However, questions regarding efficiency and long-term durability still linger. Additionally, the response characteristics and pedal feel could benefit from further enhancement before mass production. Nonetheless, the system's immense potential is already evident.

Earlier this spring, Gobao welcomed us to their headquarters, where we gained insights into the development of the drive system, its manufacturing processes, and the company's long-term strategic vision.

No Derailleur, Reduced Chain Wear, and Lower Maintenance

The X1P has been specifically designed for Gates Carbon belt drives, completely eliminating the need for a cassette, derailleur, shifter, and shift cables. This design not only minimizes maintenance but also reduces the unsprung mass at the rear suspension.

According to Gobao, the Gates CDX belt outlasts traditional chain drivetrains by approximately three times. The system also promises nearly maintenance-free operation.

Fast Charging: Under 30 Minutes

Equally impressive as the motor is the new fast-charging technology. With a charging capacity of up to 1,500 watts, Gobao promises remarkably brief charging times. The manufacturer claims that the 500 Wh battery can reach 80% charge in just 24 minutes, the 750 Wh battery in 28 minutes, and the 900 Wh battery in only 32 minutes. This would place the system well ahead of current eBike drive systems. For reference, a Bosch PowerTube 800 takes approximately 2.5 to 3 hours to achieve 80% charge, while Avinox requires about 2 hours and 20 minutes for its 800 Wh battery using a 12 A charger.

Gobao is also pursuing ambitious goals for weight and energy density. The 500 Wh battery is claimed to weigh only 2.6 kg, the 750 Wh variant 3.6 kg, and the 900 Wh version 3.7 kg. This means the largest battery is roughly 300 grams lighter than the 800 Wh battery used in the Avinox system while offering greater capacity. Despite its impressive output of 1.5 kW, 30 amps, and 52 volts, the accompanying charger remains relatively compact and lightweight at around 1.2 kg. If these specifications hold true in real-world scenarios, Gobao could redefine charging speed standards in the eMTB sector.

Display Comparable to Avinox?

The system features a modern HMI with a touchscreen and USB-C charging port, GPS and GSM modules, wireless remotes, and over-the-air updates. Riders can customize motor characteristics and shifting behavior via an app. While the display does not yet fully match the smartphone-like experience of the Avinox system, Gobao is already performing at a high level, and the remotes feel robust.

To make the X1P ready for public demonstration, Swiss engineering firm Radiate developed a complete carbon bike platform around the new drive system in just two months. This concept encompasses Enduro, All-Mountain, and SUV variants, with the lightest All-Mountain model reportedly weighing only 20.5 kg while housing a 750 Wh battery.

Final Thoughts on the Gobao X1P

While crucial questions about durability, efficiency, and initial production partners remain, the Gobao X1P is already one of the most exciting innovations showcased at EUROBIKE 2026. It left a positive impression during initial test rides, despite still being a prototype.

While Avinox is offering a glimpse into the future with its MG Concept, Gobao is presenting a product that feels surprisingly close to market readiness. If the system can deliver on its promising initial test rides and technical specifications, the X1P may become the first gearbox motor to establish itself as a long-term solution for many eMTBs and pose a serious challenge to Avinox in the competitive eBike motor market.
