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.

I see that no one answered this thread and it is similar to mine which I just started. From the information I've obtained from two companies overseas that sell these devices, the Pear Tune 4.0 and the Speed Fun Ribelle and Furious will work the Ribelle showing real time data (speed, etc) the Furious not. However, whether these actually work in practice is something I am attempting to find out on my thread. . .if you found an answer somehow would appreciate knowing. . .
