+E-Tube port versio , pyörään jossa on erillinen käynnistin nappi.
From the ground up   tuning chip for your e-bike with a Shimano motor – with a new design and completely new hardware and firmware.

The tuning chip SpeedBox 1.2 enables you to suppress the speed limiter on your electric bike. When in use, the actual speed will appear on your display up to 23 km/h.

Compared to previous versions, this new product also plugs into the engine’s E-Tube port. It is therefore necessary that the e-bike motor in which you are going to install the new version of SpeedBox for Shimano has one free E-Tube port. It is not possible to install SpeedBox products for Shimano without a free E-Tube port in the engine.

E-bikes, which do not have a free E-Tube port, are usually those with a Di2 electronic gear shifting system or with a wheel frame integrated Satellite System ON/OFF Switch (EW-SW100, EW-SW300).

How does SpeedBox 1.2 work?

This tuning chip can also be easily controlled with a LIGHT button. If the lights are turned off, SpeedBox is activated. The chip can be deactivated by turning on the lights. If you want to use tuning independently of the lights, do not connect the red wire during installation, like that the tuning will be always activated. If you do not have lights on your e-bike, SpeedBox 1.2 will also be activated at all times.

Assembly

We use original connectors for the production of SpeedBox chips ensuring that the installation process is very simple and the chip is connected properly. We have also prepared detailed instructions and videos to make installation easy for you. Disassembly of the tuning chip is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us.

If you are planning to install SpeedBox on a brand-new bike, make sure you ride it for at least 1 km before the chip is activated.
