The Avinox M2S is one of the most powerful and advanced e-bike systems available today.
Designed for modern electric mountain bikes, it combines extremely high torque and power with a surprisingly lightweight and compact design.
Already featured on selected Amflow and Whyte models, the M2S is set to become a major player in the e-MTB market, offering riders a new level of performance without compromising handling or ride feel.

Avinox delivers significantly higher peak output while keeping weight competitive, making it ideal for riders who want maximum assistance without sacrificing handling.
Lightweight performance
High power is only really useful if the bike still feels balanced and enjoyable to ride. That is where the Avinox M2S stands out.
At around 2.59kg, the motor remains impressively light for the level of output it delivers. This gives it one of the strongest power-to-weight ratios currently available in the category.
In real riding terms, that helps the bike feel agile, responsive and easier to manage on the trail, rather than overly heavy or cumbersome. You get the benefit of the extra power without losing the lively handling that matters so much on a performance e-MTB.
Avinox M2 vs M2S
The Avinox platform is available in two versions, M2 and M2S. Both are designed to deliver a modern, lightweight and powerful ride experience, but they suit slightly different riders and priorities.
The M2 is still a very capable system, offering strong assistance and a lower-tier entry into the Avinox platform. The M2S builds on that with more torque and noticeably more peak power, making it the more aggressive option for riders who want maximum support on demanding climbs, technical terrain and harder trail riding.
125Nm peak / 1100W
A strong, well-balanced option for riders who want plenty of support and modern integration, without stepping right to the top of the range.
150Nm peak / 1500W
The higher-output system, built for riders who want the most powerful and capable version of the platform currently available.
In simple terms, both systems are impressive, but the M2S is the one to look at if outright performance is a priority.
Bikes with Avinox M2S
If you want to experience the system for yourself, these Amflow PX models are a great place to start. Both combine the Avinox M2S drive unit with lightweight carbon frames, 700Wh batteries and premium trail-ready specifications.
