Avinox is doubling down on the high-power e-MTB arms race with the release of its second-generation drive units: the standard M2 and the premium M2S. Pushing boundaries in torque, peak wattage, and battery energy density, these new motors aim to deliver class-leading power without compromising on weight or ride feel.
⚡ Power & Performance Specs
Avinox has engineered two distinct tiers for their new motors, both of which outpace many current market leaders in raw output:
Avinox M2S (Premium): * Continuous Power: 1,300 W & 130 Nm
Peak Power (30-second Boost): 1,500 W & 150 Nm
Weight: 2.59 kg
Tech Upgrades: Utilizes flat wires inside the motor to maximize space and current, raising the maximum potential efficiency to an impressive 84.5%.
Avinox M2 (Standard):
Continuous Power: 1,100 W & 110 Nm
Peak Power (30-second Boost): 1,100 W & 125 Nm
Weight: 2.65 kg
Tech Upgrades: Uses larger-diameter round windings to handle extra current, achieving a maximum potential efficiency of 83%.
Weight Context: Both motors are slightly heavier than the original Avinox M1 (2.52 kg) but remain highly competitive, undercutting rivals like the Bosch CX Race (2.7 kg).
🔇 Noise Reduction & Durability
High power often comes with loud mechanical noise, but Avinox has tackled acoustic management directly:
The M2S utilizes a dual-gear meshing design specifically engineered to eliminate gear-play noise on descents.
The M2 employs helical gears to significantly reduce knocking and rattling sounds.
Durability: Both drive units boast an IP66 rating, featuring enhanced waterproof performance at the connectors and increased resistance to internal wire twisting.
🔋 Next-Generation Batteries
Avinox introduced a brand-new 700 Wh integrated cylindrical battery designed for frame stiffness and weight reduction.
Weight: 3.18 kg
Energy Density: A staggering 220 Wh/kg.
Note: The wider, removable 600 Wh and 800 Wh battery options are still available for compatible frames.
📱 Display & Smart Connectivity
The software and cockpit experience have also received major quality-of-life updates:
Navigation: The 2-inch OLED Avinox display can now import routes directly from third-party apps like Komoot to provide turn-by-turn directions.
Heart-Rate Syncing: Riders can now pair a heart rate monitor directly to the system. The motor can be set to automatically scale its assistance up or down to keep the rider within a pre-set heart rate zone.
🚵♂️ Initial Ride Impressions
Despite the jaw-dropping stats on paper, the on-trail experience remains refined. Reviewers noted that the immense power is surprisingly intuitive and easy to control. The Automatic mode shines by seamlessly adjusting assistance based on rider output and speed. Furthermore, the acoustic updates have paid off—climbing is remarkably quiet, emitting only a subtle whir when pushed close to maximum wattage, with no distracting clacking on the descents.
Here's a (not exhaustive) list of bike manufacturers known to have at least one e-bike with the Avinox M2/M2S drive unit on the way.
