The Avinox Press Team Aims to Justify its Super Powerful New M2S Motor
Summary By: eMotoX
Avinox has introduced its latest eMTB drive unit, the M2S, which significantly raises the bar in terms of power output within the electric mountain biking sector. Building on the success of its predecessor, the M1, which was already the most powerful motor on the market at 850W peak power, the M2S offers continuous peak power of up to 1300W and torque reaching 130Nm. It also features short-term Boost modes delivering an impressive 1500W and 150Nm of torque. Despite these high figures, the M2S remains compliant with speed limits, restricted to 20mph in the US and 25kph in Europe, meaning its increased power does not translate into higher top speeds.
The release of the M2S comes amid an ongoing "motor power war" in the eMTB industry, with competitors like Specialized and Bosch recently increasing power outputs of their drive units through over-the-air updates. Specialized’s 3.1 and 3.1 S-Works motors and Bosch’s Performance Line CX units have all seen boosts in torque and power, challenging the boundaries of regulatory limits. Avinox’s new motor, however, pushes these boundaries further, sparking debate about the necessity and practicality of such high power levels, especially given that many riders rarely utilise the full potential of existing motors.
Cory Benson, a tester who has ridden both the M1 and M2S units, praises the flexibility and tunability of the Avinox systems, particularly valuing the ability to adjust power output to suit different riding styles. He notes that while the peak power figures are striking, the real-world experience of power delivery and control is what matters most. Benson also compares the M2S favourably with the latest Specialized 3.1 S-Works motor, though he highlights the distinct advantage of Avinox’s Boost mode for short bursts of extra power.
The introduction of such a powerful motor has raised regulatory concerns, especially in the US, where federal and state laws typically cap e-bike motor power at 750W nominal or peak. Proposed legislation, such as California’s SB 1167, threatens to prohibit the sale of e-bikes exceeding these limits, complicating the market for high-powered units like the M2S. Avinox acknowledges the regulatory challenges but argues that power should be viewed as a tool to enhance rider capability rather than speed, emphasising that their systems comply with speed restrictions and are designed to improve access to challenging terrain safely and reliably.
Avinox’s press team defends the M2S’s power output as a means to expand the possibilities of mountain biking, allowing riders to tackle steeper climbs and more technical trails without sacrificing control or safety. They stress that power and speed are distinct factors, with power aiding acceleration and handling in difficult conditions rather than increasing maximum velocity. As the eMTB landscape evolves, the debate over motor power, regulatory compliance, and rider needs is set to continue, with Avinox positioning
