• 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.

As an owner of a Cube with a gen 4 motor that has had a Speedbox 3.0 fitted for 800+ trouble free miles, I'm interested by the new Bosch update but as other's have expressed, is this another attempt by Bosch to eradicate tuning once and for all or do you hope they've done with that aspect, as whatever they do, someone will be able to undo it?
I don't think I'll jump in at the deep end on this update until others have proved tuning still works, I prefer the ability to have assistance above 15mph over an increased 10Nm, which I may or may not notice.
