SpeedBox 3.0 Tuning Chip for Brose / Specialized Motors

SpeedBox 3.0 is a tuning chip for e-bikes with Brose motors, including Brose SPECIALIZED systems. It removes the factory speed limiter, lets you set your own speed limit, and keeps actual values on the e-bike display.

Tuning is switched on and off with the WALK function or a + - + - button sequence. This version does not connect to the SpeedBox Connect app.

Good to Know
