SpeedBox 1.2 Tuning Chip for Shimano E8000 / E7000 / E6100 / E5000 + E-Tube Port

SpeedBox 1.2 Tuning Chip for Shimano E8000 / E7000 / E6100 / E5000 + E-Tube Port

SpeedBox 1.2 is a redesigned tuning chip for e-bikes with Shimano E8000, E7000, E6100 and E5000 motors, with new hardware and firmware. It removes the speed limiter; the display shows actual speed up to 23 km/h.

It can be controlled with the LIGHT button: tuning is on when the lights are off and off when the lights are on. If the red wire is left unconnected during installation, or the bike has no lights, tuning is active at all times. This version does not connect to the SpeedBox Connect app.

This variant adds an E-Tube port, for motors that do not have a free one.
