derestrict

Hello team, I’ve been reliably informed that Bosch’s smart system tech doesn’t allow their motors to be destricted so a speed box is essentially impossible to install. Specifically on their Tinker2. Any info on this would be most welcome.

I’m having a hard time finding someone from Montréal, Québec, Canada to derestrict or unlock my eBike to get top speed? can anyone refer me to someone or a good tutorial as to how to do it myself? Cheers, Dd
