Ezi Hyperide S controller

[AlienWalker84]

Hi. I want to know what controller is in the new EZI Hyperide S. Mine is limited to 30 km/h and I know it can go 45 km/h, but I can’t figure out how to change it. Some said to find a blue/yellow wire and short it to ground, but no luck there. Others said to hold the front brake and throttle, turn it on and hold for 5 seconds — no luck there either.

I got a picture of the controller in it. Can anybody ID the controller?

Best Wishes,
Stefan
