• 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.

Has anyone successfully derestricted a Pinion MGU with the BikeSpeed RS?

I have changed the pulleys and updated the gear ratio's using the Bikespeed RS Module but it always throws an Error and shuts down.

Thanks

It,s not possible As far as I know, FIT has blocked any option to derestrict this engine after last firmware upgrade
be careful about trying it to many times , because after a limited failed attempts and errors , the motor will enter protection mode and you’ll have to take your bike to the dealer to reset the software
