The SpeedBox 1.2 B.Tuning for Shimano is a high-end untuning module designed for electric bikes equipped with Shimano E8000, E7000, E6100 and E5000 motors. This module removes the 25 km/h assistance limit, allowing smooth assistance up to much higher speeds, while maintaining accurate data display on the bike's screen.
Thanks to its Bluetooth connectivity, the SpeedBox 1.2 B.Tuning synchronizes with the SpeedBox App mobile application (available on iOS and Android). This app lets you customize maximum speed, track performance in real time (cadence, power, speed, range), record trips and manage tuning activation directly from your smartphone.
Installation is simple, thanks to color-coded connectors that do not require soldering. We recommend a 10 km ride before activating the module on a new bike.
