Speedbox Shimano 1.2 E8000/e7000/e6100/e5000 Speed Increasing Device

E-bike tuning chip compatible with Shimano motors E8000, E7000, E6100, E5000. Not compatible with the SpeedBox App. Display: accurate values up to 23 km/h, then accurate values only in the app. This chip is easy to operate with the LIGHT button. If you want the tuning always active, independently of the light function, connect the fork of the SpeedBox device to the terminal marked with “-”. If the bike is not equipped with lights, the SpeedBox remains always active. To connect the SpeedBox chip to an e-bike, we use color-coded connectors equipped with a key for correct connection, making chip installation truly easy. We have written detailed instructions and created videos that allow every customer to install the SpeedBox. Removing the tuning chip is as simple as installation. If you have any connection issues, please don’t hesitate to contact us. If you want to install a SpeedBox on a brand new bike, you must ride at least 10 km on this bike before starting the chip for the first time. https://youtu.be/DQaW6irHP6A?si=PNiZLGA9UsrWjgc0
