We had powerful motors before Avinox:
- Sachs – 112 Nm
- Rocky Mountain Dyname – 109 Nm
- Bafang M620 – 170 Nm
Progress is always welcome in any field. However, I personally feel that focusing solely on
maximum power does not help in fully understanding the overall situation.
Avinox has brought a completely different perspective on what assistance from an eBike motor can be.
Below, we can identify three major assistance curves:
- Avinox
- Shimano/Specialized
- Bosch
It is easy to see that for the motor to deliver
400 W, the rider only needs to supply approximately:
- Avinox – 50 W
- Shimano/Specialized – ~75 W
- Bosch – ~120 W
For a motor output of
600 W, the required rider input is roughly:
- Avinox – 75 W
- Shimano/Specialized – ~120 W
- Bosch – ~200 W
From this, we can quickly conclude that
Avinox is characterized by
low rider power input and high motor power output, while
Bosch represents the opposite approach, with
Shimano/Specialized positioned in the middle ground.
Unfortunately, we cannot directly compare
SL motors on
ebike-lab.de, but it is reasonable to deduce that they fall below the
Bosch CX4/CX5 in terms of assistance. This implies
higher rider power input and
lower motor power output.
It is here that I believe we are witnessing the emergence of a
new class of eBike motors, characterized by
low rider input and high motor output—an
“Avinox Class.”
Personally, I am not particularly drawn to this low-input/high-output approach. I have tuned down the
Tour mode on my
Bosch CX4 to
450 W and
60 Nm, with
ECO set to even lower values. While I can still use
Turbo or
eMTB+ modes for very steep or technical climbs, what I truly seek is the
bike experience—without the suffering, but also without excessive motor assistance.
I do believe that
Avinox systems can be configured for lower power output. However, whenever I read reviews, the emphasis is almost always on maximum power. For that kind of experience, I would rather use my
300cc two-stroke enduro/hard-enduro motorcycle.
The Avinox Effect – How a Manufacturer Disrupted an Entire Market
Anyone interested in eMTBs has likely heard about the
Avinox motor. When
DJI released the
Avinox M1 in 2024, it immediately disrupted established players such as
Bosch,
Specialized,
Shimano, and
Giant. The surge in power triggered a “power race,” with Bosch increasing the torque of its latest Performance Line CX (“Gen5”) from 85Nm to 105Nm, while Specialized enhanced the output of its non-S-Works models. Shimano has maintained its EP801 at 85Nm, and Giant, despite...
