The new Avinox MG motor could be one of the biggest shifts in eMTB drivetrain design.

Just months after launching the impressive M2 and M2S motor systems, Avinox has revealed something much bigger. A gearbox motor. And if early signs are anything to go by, this is not just another concept designed to generate headlines at Eurobike.

This looks very real.

At Eurobike 2026, Avinox revealed the new MG (Motor Gearbox) platform — a next-generation e-bike motor system that integrates both the motor and gearbox into a single unit. That means no rear derailleur, no cassette, no traditional gear system, no mechanical shifting at the back of the bike. Instead, everything happens inside the motor unit.

That alone is a huge deal. But what makes this even more interesting is what Avinox appears to be building.

Is the Avinox MG a CVT eMTB motor?

From what has been revealed so far, the Avinox MG system appears to use a CVT-style (Continuously Variable Transmission) drivetrain or something very close to it. Rather than fixed gears, Avinox describes the system as using stepless virtual gearing. That means riders may be able to choose:

• 4-speed setup
• 5-speed setup
• Traditional 12-speed feel
• Fully automatic shifting
• Or no defined gears at all

Instead, the motor simply maintains optimal cadence automatically. This is where things get exciting. If Avinox delivers this properly, it could eliminate one of the weakest points in modern eMTBs.

Why this matters for eMTB riders

Modern eMTBs have become incredibly powerful. But drivetrain durability remains one of the biggest pain points. Rear derailleurs still get smashed. Hangers still bend. Cassettes still wear. Chains still suffer under high torque. For aggressive trail, enduro, and gravity-focused riders, drivetrain damage is almost accepted as part of riding.

The Avinox gearbox concept could change that.

That last point is especially important. By moving drivetrain mass away from the rear wheel and into the bottom bracket area, Avinox could improve suspension performance and overall bike handling. That is a major win for serious riders.

Auto shifting and AI support

Avinox is also pushing heavily into intelligent shifting. The MG system reportedly supports:

• Automatic shifting
• AI-assisted shifting
• Rider-defined cadence targets
• Near-instant gear changes

Avinox claims shift transitions happen in around 0.1 seconds, with no interruption in power delivery.

That could fundamentally change how eMTBs ride. Especially uphill.

This looks bigger than a concept

This is the biggest takeaway for us at Day Zero. This does not feel like a rough prototype. Avinox already has major bike brands building around the platform. At Eurobike 2026, Avinox showcased concept bikes with:

That is significant. Major brands do not invest engineering resources into something unless they believe it has real production potential. Which tells us one thing — this platform is likely much closer to production than most people think.
