When the first generation of the Avinox motor (M1) appeared on the market, it literally caused a stir in the cycling world. It offered performance that the competition had previously considered impossible. Now, the Avinox brand comes with its second generation – the M2 and M2S models. This is not just a minor evolution, but a technological assault on the position of the absolute number one on the market.
If you want to get an idea of the power of these motors, just compare: standard "full-power" motors (e.g., Bosch CX) offer around 85–100 Nm of torque and 600–750 W of peak power. Avinox essentially doubles these figures.
M2 vs. M2S: Choose your level of dominance
Both motors share the same compact dimensions and shape as the previous generation, making integration easier for frame manufacturers. However, the differences are found inside:
Avinox M2
The standard version, whose power puts most of the competition to shame. It offers a continuous torque of 110 Nm and a peak power of 1100 W. In Boost mode, however, it can briefly push itself up to 125 Nm. It weighs a solid 2.65 kg.
Avinox M2S
The letter "S" here stands for extreme power. Thanks to an improved winding (flat copper wires instead of round ones), it achieves a higher power density. In standard modes, it delivers 130 Nm and 1300 W, but in Boost mode, it pushes out up to 150 Nm and 1500 W (for up to 60 seconds). Weighing 2.59 kg, it is one of the lightest motors in its power class.
Technological finesses: Why is it better than its predecessor?
While the first generation M1 was about raw power, the M2 and M2S add sophistication and refinement.
1. Silence and the end of "clacking"
Many powerful motors suffer from the so-called "clacking" – an unpleasant metallic clicking in the gears during descents in rough terrain. Avinox used a dual gearing system on the M2S model, which completely eliminates this play and unwanted noise. The M2 model relies on helical gears, which reduces motor noise under load to a minimum. The result is a quiet, deep sound profile that is not bothersome even at maximum load.
2. Pedaling without resistance
One of the biggest improvements is the reduction of pedaling resistance without assistance (over 25 km/h or when the motor is turned off). Avinox replaced the original oil seals with new sealed low-friction bearings. Thanks to this, the resistance has been reduced by an incredible 41%. The feeling of riding "on your own power" is thus almost indistinguishable from a regular bicycle.
3. Thermal efficiency and GaN technology
Thanks to the use of gallium nitride (GaN) based semiconductors and new temperature sensors, the motor heats up much less. In practice, this means you can use the full 1500 W power for longer without the system having to "throttle down" due to overheating.
Energy that is always ready
Avinox comes with a new line of batteries that are among the most energy-dense on the market (more energy in a smaller volume):
New 700 Wh battery
A true technological gem. It weighs only 3.18 kg and, thanks to its cylindrical shape, allows building bikes with a slim downtube. Additionally, it has a higher discharge current, which is crucial for achieving maximum Boost (1500 W) on the M2S motor.
Freedom of choice: For the first time with a removable battery
For the first time, Avinox is also thinking of riders who do not have the option of parking their bike directly at a power outlet (e.g., in an apartment or hotel). It now offers removable battery variants with capacities of 600 Wh (2.96 kg) and 800 Wh (4 kg).
Although they are slightly heavier than their fixed integrated versions (due to a more robust and secure casing), the practicality is priceless. You can easily take them home to the charger or remove them when transporting the bike on a car rack, significantly reducing its weight.
Extremely fast charging
With the 12A fast charger, you can charge the 700Wh battery from 0 to 80% in just 1 hour and 24 minutes.
"Infinite" range thanks to the Range Extender
For those for whom even 800 Wh is not enough, Avinox has pulled a real ace up its sleeve. The 600 Wh battery can also be used as an external Range Extender. You simply attach it above the downtube. On compatible bikes, you get a brutal total capacity of 1,200 to 1,400 Wh.
With such a portion of energy, you no longer have to wonder if your battery will last for a whole day in the mountains – the question is rather whether your legs will be up to it. Avinox puts a tool in your hands with which you can plan routes you previously only dreamed of.
Ride performance: Brains and brawn
Power without control is useless. That's why Avinox uses an advanced Smart mode that constantly adjusts assistance according to your pedaling and the terrain. In practice, you barely notice the motor – until you start effortlessly overtaking others on a hill.
Digital gadgets
2" OLED display
Bright and readable even in direct sunlight. It allows detailed settings of everything – from the onset of assistance to the duration of Boost (10–60 s).
Apple Find My Integration
You can locate your bike just like an iPhone.
Heart rate synchronization
Connect a chest strap and the motor will change output to keep you in your chosen training zone.
Security
The bike automatically unlocks via Bluetooth when you approach it, and notifies your mobile phone if someone moves it unauthorized.
Who is already using Avinox M2/M2S?
This system is becoming the new choice for ambitious brands that want to offer more than just "standard" drives. Among the first in the greatebike.eu offer are the brands below.
Conclusion
The Avinox M2 and M2S represent more than just powerful motors. They are systems that eliminate the most common ailments of e-bikes (noise, pedaling resistance, slow charging) and add performance that turns every hill into a flat plain. If you are looking for the best that current technology has to offer, Avinox is the clear choice.
