I have a bafang mid-drive motor but was surprised to see it arrived without a speed restriction. I need to make it speed restricted so it is street legal to use. I used a programming cable and this site (https://devnotes.kymatica.com/BafangWebConfig) to set a speed limit at 25 km/h. Issue: The controller seems to think this is a dynamic speed limit to 'roughly' maintain, while cycling it doesn’t appear to go over but when I spin the wheel without a loud it goes well above 25 km/h. In my country, the police can stop and speed test bikes, so I need the motor to cut out immediately when it hits 25 km/h. Is there a firmware I can use to enforce a strict speed limit on the controller so that it cuts out immediately at 25 km/h instead of doing whatever it does currently which is roughly maintain the limit. Thanks.
