Speedbox Shimano Ep8 1.3 + E-tube Port Speed Increasing Device

Only compatible with Shimano EP800. Not compatible with other Shimano motors or Giant e-bikes. Full motor support speed independent. Correct display values up to approx. 23 km/h. This + E-Tube port version is compatible with a Di2 derailleur or a satellite system switch thanks to the additional E-Tube port When the lights are OFF, you can drive at unlimited speed. You simply turn off the chip function by activating the lights. If you want to use the tuning independently of the lights, do not connect the red plug during installation so that the SpeedBox is always active. If you don't have a light on your bike, the SpeedBox 1.3 is always ON.
