Using the kit

The SpeedBox 2 Yamaha 2019 is compatible with Yamaha PW-X and PW-SE engines equipped with the A, C or X display. The kit is activated using the light button on your electric bicycle. As soon as you press, the speed of 9.9 km/h appears on the dashboard for 2 seconds. This tells you that the Speedbox 2 is activated. The assistance of your bike will no longer be restricted and it will assist you continuously whatever the speed of your electric bike.

Detailed operation

The Speedbox 2 kit for Yamaha 2019 engine is equipped with a microprocessor to assist the cyclist beyond the 25 km/h regulations by unblocking the electric bike. The engine continues to assist the cyclist regardless of the actual speed of the bike. This module is very easy to install because the connectors fit perfectly with the original ones (the connectors remain well sealed). Once the motor is reassembled, the module is housed in the casing and therefore totally invisible. The release kit can be removed by performing the reverse operation.

You do not need to make any settings and the speedbox 2 kit is powered by the electricity delivered by your battery. The speedometer of your electric bicycle continues to display the actual data (average speed, instantaneous speed, kilometres travelled, etc.).
