• 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.

Stunlocker, quick question.

I've just used Stunlocker to up the support, in trail, on my Canyon Spectral On (E8000). At the same time, my Focus Jam 2 (also E8000) on the other side of the garage also updated itself to the same level of support, even though it was not turned on.
I've done several updates to each bike to check and every time the other bike, even though not turned on, mirrored the changes. They were around eight foot apart
Anyone know if this is normal or is my garage the potential basis of a Steven King novel?

You have entered the Twilight Zone! 😆

3 Shimano motors here E8000, Ep8RS and full Ep8 and it doesn't change the others when I make changes. Weird one for certain but E8000 is the common element,,, 🤔
