Avinox M2S (FP700)
Following the massive splash Avinox made in the summer of 2024 with their impressive market debut of the M1, the M2S has some big shoes to fill. On paper, however, it manages this effortlessly: despite weighing barely 100 grams more, it delivers significantly more power and torque, and improvements have also been made to the motor acoustics and the overall ride feel. Since its form factor and mounting points are identical to the Avinox M1, it is extremely easy for bike manufacturers to integrate.
The maximum output power of the Avinox M2S is determined by the battery used. To reach its max output of 1500 W, the DU needs to be combined with the FP700 battery

Power Characteristics
Shows how much power the motor delivers for a given rider input. The value shown is pure motor power, adjusted for input and drivetrain losses.
Input vs. Output: Avinox M2S (FP700)
The motor's characteristics have barely changed compared to the M1. Offering up to 800% assistance, it provides massive thrust even at low rider inputs, hitting its peak output at roughly 170 watts of rider power. The fact that the M2S doesn't quite reach its absolute maximum in this specific scenario is due to our standardized test cadence of 80 rpm. To unleash its full power, the motor prefers a slightly faster pedaling rate.

Cadence Behavior
Shows the optimal RPM range.
Power vs. Cadence (Relative (%))
Just like the M1, the M2S requires a higher cadence to truly hit its peak performance. In our test scenario at 130 watts of rider input, it reaches its maximum at around 105 rpm. After that, however, it remains highly consistent without any power drop-off—a level of stability we've previously only seen from Bosch. Hats off!
Thermal Performance
Shows power output performance over 15/20 minutes under constant full load.
20 min
When combined with the FP700 battery tested here, the M2S demonstrates truly impressive thermal performance. Despite a constant motor output of over 1000 watts, it remains absolutely stable for over 20 minutes. Only the dropping battery voltage causes a slight dip in performance, falling to around 92% by the end of our test. However, a word of warning: after 20 minutes, the M2S casing exceeded 120°C, posing a genuine risk of burns.
