Hi there. I'm a Davinci owner as well and have spent 5 years trying to find ANY info that I could on them. Unfortunately, there is nothing available that I've found BUT I started comparing specs with other manufacturers and found that Motorino is the closest to the Davinci that I can find. I also had a friend searching and he just messaged me that he found the wiring schematics for my bike which is a Davinci 72 volt. As soon as I get it from him I will message you.
