THE SpeedBox 1.3 B.Tuning for Shimano EP8 is a high-end release module designed for electric bikes equipped with Shimano motors EP8, EP800 And EP8RS. This module removes the assistance limit at 25 km/h, allowing smooth assistance up to much higher speeds, while maintaining accurate data display on the bike screen.
Thanks to its connectivity Bluetooth, the SpeedBox 1.3 B.Tuning synchronizes with the mobile application SpeedBox App (available on iOS and Android). This application allows you to personalize the maximum speed, monitor performance in real time (cadence, power, speed, range), record journeys and manage tuning activation directly from your smartphone.
Installation is simple with color-coded connectors, with no soldering required. It is recommended to ride approximately 10 km before activating the module on a new bike.
A “+ E‑Tube port” version is offered for engines where all E‑Tube ports are already used (e.g. bikes with Di2, integrated satellite systems, or E5000 engines).
