Upgrade your Shimano motor e-bike with this amazing basic tuning kit. The SpeedBox 1.2 can double your e-bike's speed limit from 25 km/h to 50 km/h. As you ride, the display shows the actual speed up to 22 km/h, then stabilizes and keeps the same reading even at higher speeds. The motor's electric assistance stops when you hit 50 km/h. If your bike has no lights, the SpeedBox 1.2 is always on. With lights installed, you can activate the tuning chip when needed on the bike's control panel. When the lights are off, you can reach 50 km/h, and turn the lights on to deactivate the chip. The SpeedBox chip has color - coded connectors for easy installation, and we've got detailed instructions and videos to help. Disassembly is a breeze too. If you're putting it on a new bike, ride it for at least 1 km before activating the chip.

Using the SpeedBox 1.2 is easy. First, install the chip on your Shimano motor e - bike. The color - coded connectors make it simple. Just follow our detailed instructions or watch the videos.
