DO NOT, I REPEAT, DDOO NNOOTT, change the settings/parameters on your newly Amyet S8 Electric bike. Doing so will result is so many issues with performance. Your bike will lose power. You will go from 28MPH out the box, to 15 MPH to NONE just from messing with the parameters on the display while holding up+ and down- simultaneously. JUST LEAVE IT ALONE out the box. I understand that most/other E-Bike can be faster by changing the settings, but doing so on this specific E-Bike on the Amyet S8 will result in failure to perform at its full potential. It is NOT like other bikes seen on YouTube or reddit post. Just LEAVE THE BIKE ALONE, PLEASE. If you want to make your bike faster, please follow these steps.

For powerful performance and faster speed, Operation method of lifting speed of S8:

1. Press and hold the left brake lever for 10 seconds and turn on the bike (do not release the brake lever during the process). Continue to Hold the brake lever for 10 seconds and release the brake lever.
2. Turn on dual motor mode and set PAS to 5.

This is a much safer way to unlock your bike without changing any parameters in your settings on your bike. I went from 28MPH out the box to 36MPH on a full charge.
