SpeedBox 1.3 B.Tuning for Shimano EP8 is a high-end untuning module designed for electric bikes equipped with Shimano EP8, EP800 and EP8RS motors. This module removes the 25 km/h assistance limit, enabling smooth assistance up to much higher speeds, while maintaining accurate data display on the bike's screen.
Thanks to its Bluetooth connectivity, the SpeedBox 1.3 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.
A "+ E-Tube port" version is available for engines where all E-Tube ports are already in use (e.g. bikes with Di2, integrated satellite systems, or E5000 engines).
