Do I need to derestrict an ebike for general use?
no, you can go faster than 16mph but it's hard work with a 20 odd kg bike and beefy tyres.
I guess most people just bounce around 15mph with the motor kicking in and out, it's boring if your on any long straights.
probably will still seem really good for the first month or so, then you'll end up wishing you can go faster.
if you get a 5th gen motor theres probably absolutely 0 chance if can be derestricted, seems 4th gen probably can be now with bikespeed rs
but you'll ruin your warranty if it gets detected, so I'd avoid trying one out for 2 years.
IDK what motor you'll end up with but bosch cx are something crazy like 600+ outside of warranty.
They can handle the speed as there's S pedelecs in the states with the same motor and no restriction that can go upto 28mph
it would just suck if you ended up with a motor that dies early in the warranty period, but the software has flagged that you've derestricted it.
police will seize derestricted biles btw, and you get charged with something like driving a motor vehicle without insurance etc, because they no longer class it as a bike.
your risk of being caught are probably like 0.0% unless your an idiot, but its still something to consider....
