Avinox M2 & M2S Motors Explained

The latest generation of Avinox motors — the M2 and M2S — build on the already powerful M1 system, bringing more performance, improved efficiency and a more refined ride feel.

While the headline figures grab attention, the real story is how these motors have evolved in terms of power delivery, efficiency and overall ride quality.

From M1 to M2: What’s Changed?

The original Avinox M1 motor already stood out in the e-MTB market, delivering significantly more power than most competitors. The new M2 and M2S motors take that platform further with a number of key improvements.

• More power: Increased output across both motors
• Higher efficiency: Improved energy conversion from battery to motor
• Reduced drag: Less resistance when pedalling unassisted
• Quieter operation: Updated internal gearing reduces noise
• Refined control: Smoother and more responsive power delivery

Avinox have also redesigned internal components, including motor windings and gearing systems, to handle higher power more efficiently while improving long-term durability.

M1 vs M2 vs M2S: Key Specifications

Peak power on the M2S motor depends on the battery used:

• 700Wh integrated battery: Up to 1500W peak power
• 800Wh removable battery: Up to 1300W peak (1500W Boost mode)
• 800Wh integrated battery: Up to 1300W peak and Boost

This means the system isn’t just about the motor itself — the battery plays a key role in how much power is available.

For context, many traditional full-power e-bike motors sit around 85Nm and 600W, highlighting just how far the Avinox system pushes performance.

What Makes the M2S Different?

The M2S is the higher-performance version of the system, designed to deliver more sustained power and higher peak output.

It uses upgraded internal construction, including flat wire motor windings, which improve efficiency and allow it to handle higher loads more effectively.

This results in stronger performance under sustained effort and more available power when needed, particularly in demanding riding conditions.

Where the M2 Still Stands Strong

The M2 is not simply a “lower spec” motor — it is still a highly advanced system and a significant step forward from the original M1.

With upto 1100W of power and up to 125Nm of torque, it already exceeds the output of most traditional full-power e-bike motors.

For many riders, the M2 offers more than enough performance, combined with the same core technology, efficiency improvements and refined ride feel as the M2S.

Efficiency, Noise & Ride Feel

Beyond raw numbers, the biggest improvements come in how the motors feel on the trail.

• Improved efficiency (up to ~84.5%)
• Reduced mechanical drag when pedalling
• Quieter operation thanks to revised gearing
• Smoother and more controlled power delivery

These changes make the new generation motors feel more natural and refined compared to the already capable M1 platform.

Battery Integration & System Design

The M2 and M2S motors are part of a complete system, working alongside new battery options including:

• 700Wh integrated high-density battery
• 600Wh and 800Wh removable battery options

This flexibility allows brands like Amflow to build bikes with different ride characteristics, from lightweight integrated designs to higher-capacity removable battery setups.

Where You’ll Find These Motors

The latest Amflow bikes use both versions of the Avinox system depending on the model:

• M2 Motor: Found on the Amflow PR
• M2S Motor: Found on the Amflow PR Pro, Amflow PX Pro and Amflow PX

This allows riders to choose between a more accessible setup with the M2, or the highest performance option with the M2S system.

Final Thoughts

The M2 and M2S motors represent a clear evolution of the Avinox platform, improving on the already impressive M1 with more power, better efficiency and a more refined ride experience.

Importantly, both motors sit well above what has traditionally been considered “full power” in the e-bike world.

The difference between them is not about one being basic and the other advanced — it’s about how much performance you want from an already highly capable system.
