Preeto Electronic Rear Derailleur and Shift Controller

PG1 is Preeto's first electronic shifting system for eBikes. The rear derailleur supports 10- or 11-speed drivetrains with an 11T to 50T cassette range and communicates with the wireless handlebar shift lever through the eBike's CAN bus. Powered by the bike's 12 V system, PG1 combines stable manual shifting with a wireless response time of less than 60 ms and provides a platform for future automatic-shifting customization.
