• 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.

Badass box on Bosh smart system

Does anyone have experience with the Badass box on the Bosh smart system?
I have a bosh smart system with a spoke magnet. I would like to use the badass box.
Will it generate errors or does it work just fine?

I wonder if the existing rotor magnet must be removed and a spoke magnet used instead? It looks to me that the signal rate to the sensor is changed (rpm rate). Hence the AA battery which allows the speed box to be isolated. Btw, I’m not familiar with this at all. Looks interesting though but 40kmh is +8kmh more than what I have now.
