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.

It's just amazing you ask a simple question and you get these really not bright holier-than-thou trolls that need to get a life always coming out of the woodworkAgain, I don't use the de-regulator on trails in part due to the exact reasons you mentioned, but also because the only time I'm going over 25mph on trails is when going downhill w/gravity (gravity=no pedaling=no pedal assist) and riding at +30mph down a trail isn't uncommon. With that said, I've gotten a traditional full suspension mtb up to 46mph downhill on a paved road before..but I had to earn that. But I don't need (or use) the de-regulator on trails. Also, the argument against e-mtbs on trails (like in Soquel Demonstration State Forest near Santa Cruz, CA where they are banned) is because (and this is their explanation) it increases the number of riders as it wouldn't simply be those physically fit enough to ride using the trails now (these also tend to be more novice riders and are at times unaware of trail etiquette). It is this potential increase in usage that would impact the trail systems. Next, more than anything else the laws exist to create a deliniation between a "motor bike" vs. a "motorized bicycle" as the prior would require insurance, registration and a license plate. Introducing manufacturing regulations is a common legislative approach when it comes to things like this. So, unless I was on pavement it wouldn't even be turned on...beleive it or not there's actually a way to turn a chip-based de-regulator (like SpeedBox) on and off via the controller. Again, IT WOULD ONLY BE USED ON PAVEMENT...and I bike at high speeds on pavement when on my road bike on a regular basis. Folks should do a bit of research on de-regulators/de-restrictors; they should gain an understanding of the various use cases and familiarize themselves with the impetus behind the laws. Unfortunately, the viewpoint many have tends to be rather myopic and lacking of much actual information beyond the typical narrative. Finally, a de-regulated e-mtb is a far cry from even a pit bike...and there's no throttle to gas through berms which is what usually causes the most damage. If you personally don't like de-regulators that's fine...but step down from the soapbox and go start your own thread where those pros and cons and individual perspectives can be discussed...that definitely isn't the topic of the my post/thread. Cheers mate.
