SpeedBox 1.2 Tuning Chip for Shimano E8000 / E7000 / E6100 / E5000

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 version plugs into the motor's E-Tube port, so your motor needs one free E-Tube port. If it does not have one, choose the + E-Tube Port variant (SB12-S+ETP).

Key Features

• Maximum speed: unlimited
• Display: shows actual values up to 23 km/h
• Activation: lights off = tuning on, lights on = tuning off
• Always-on option: leave the red wire unconnected
• Connection: plugs into a free E-Tube port on the motor
• SpeedBox Connect app: not supported

Compatibility

• Shimano E8000, E7000, E6100 motors with a free E-Tube port
• Not compatible with motors without a free E-Tube port (use SB12-S+ETP)
• Not compatible with the SpeedBox Connect app

Good to Know

• Bikes usually without a free E-Tube port: those with Di2 electronic shifting, those with a tube-integrated Satellite System ON/OFF switch (EW-SW100, EW-SW300), and all E5000 bikes. These need SB12-S+ETP.
• For actual speed and ride data in the SpeedBox Connect app, see SpeedBox 1.2 B.Tuning for Shimano (SB12BT-S).
