SpeedBox2 for Yamaha PW-SE 2019, PW-X 2019 and PW-TE is a revolutionary process-control module which  suppresses the speed limiter of your electric bike. After installation and activation of your SpeedBox for Yamaha  the display will show actual values. Values such as maximum speed, average speed, distance travelled daily and range are correctly displayed.

If you have a new bike which hasn't been ridden at all, you must ride it at least 1 or 2 kilometers before you install the SpeedBox tuning kit.

The SpeedBox2 for Yamaha is activated by pressing the LIGHT button, which is  located on the control panel. After pressing this button, the current speed of (9.0 km/h) is displayed on the control panel for about 2 seconds. This confirms that the SpeedBox2 is activated, and the supplementary assistance of your electric motor will now work up to a speed of 50 km/h.
When you press the LIGHT button again, the current speed of (2.0 km/h) is displayed. This confirms that the SpeedBox2 is deactivated, and everything works as if the SpeedBox had never been installed. The supplementary assistance of your electric bike now works up to its original speed limit of 25 km/h.

I don't agree that speedbox doesn't impact displayed range information. Prior to chip installation what was displayed on the bike and on the app agreed, now both displays show different values.


Describtion says speedbox is activated by pressing the light button. I Have lights in my bike that are activated by pressing the light button... Can I use the lights anymore if I Install the speedbox?

Bike is Haibike sduro tekking 4.0 (2019)


I bought SpeedBox2 for my 2019 SDURO FullNine 8.0 500Wh bike. When I installed it it seems working fine except for the range and battery state. After installation display showed 84 km of range while before it was 71 km (no battery charging during installation process), Haibike app shows 68 km of range. Are you aware of a problem with displayed range and battery condition after chip installation?

Dear Lukasz. Please look for more information on the internet. Yamaha never provide accurate range information. There is many things what can effect this. You could just switch mode and then 'the problem' occurs. SpeedBox has no negative effect on your range.


How can I know if the speed limit is on or off on this type of screen ( ?

Thank You.
