Power Delay Issue on a Flat Road
In the Video that I present below it is possible to verify the existence of the problem even in flat roads.
I would also like to mention that when I made this video I did not detect the problem.
Perhaps due to kinetic energy. It was when I saw the video that I noticed. But on steep roads the effect and the lack of power are quite felt due to the delay.
The following can be seen:
- At (minute: s, ms) 1: 14,397 I stopped pedaling
- At (minute: s, ms) 1: 20,307 I started pedaling again.
6s877ms later.
- 100 ms later the motor current starts to increase.
- only 1m485ms later the PWM starts to increase.
If PWM = 0 the motor power is zero.
Power Delay Issue it is more visible, on youtube, if the video is being presented with a playback speed of 0.25.
The video was recorded at a speed of 30 frames per second.
With the free Windows VideoPad program that you can download here

As I showed in a previous post, the Power Delay Issue is more evident and critical on steep roads, or unpaved paths.
It is also shown that the delay is greater with the highest assistance levels.
However, even at assistance level 9 you can see the delay in the video.
Above Level 9, I do not recommend using these levels on MTB circuits.
In the various Videos I made, and the tests I did, what I was able to verify is that all levels of assistance can be used.
Up to level 20, it can be used without any problems and instability.
It also seems to me that the torque sensor is not a problem.
I hope that this information will help to solve this issue, if there is a solution to the problem.
