Use Case

La SpeedBox 2 for your engine Giant 2019-2021 equipped with a ONE or EVO console (see below) is activated by pressing the WALK button on your box. As soon as you press the WALK button for 2 seconds, the motor will no longer be retained and will be able to assist you whatever your speed.

To turn off the Speedbox 2.1, just press the WALK button again. This means that your Speedbox 2.1 is disabled, so the assistance of your engine Giant will stop at 25 km / h.

2019 models equipped with the ONE control do not have a display. The only way to know if the kit Speedbox Giant 2.1 is active or not is to exceed 25 km / h.

How it works

Kit compatible with all engines GIANT equipped with RideControl ONE or EVO (see photo).

The kit Speedbox 2 for the motor Giant 2019 is equipped with a microprocessor that allows you to run your electric bike motor beyond the 25 km / h regulations. The motor continues to assist the rider regardless of the actual speed of the bicycle. This module is very easy to install because the connectors adapt perfectly to the original ones (the connectors remain well sealed). Once the motor has been reassembled, the release kit is housed in the housing and therefore completely invisible. It is possible to remove the kit from the console Giant ONE by performing the reverse operation.

You don't need to make any settings and the kit Speedbox 2 is powered by electricity supplied by your battery. The speedometer of your ebike Giant displays actual data (average speed, instantaneous speed, kilometers traveled, etc.).
