• Warning!!

    Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.

    Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.

Have you tried changing the battery in the badass yet?
[/Q yes just done that it seems ok just now but I’m worried incase it happens again iv heard the new Bosch motors have anti deristricrion three attempts and it bricks your motor ?

No, it's just the battery running out on the badass.
The batteries don't seem to last very long and it's happened to my friend a few times now who rides a bafang powered bike.
Instead of just defaulting to the stock speed, it throws up errors and shuts off.
