Reliable second generation tuning chip for e-bikes with Bosch motors.

SpeedBox 2.0 tuning chip enables you to suppress the speed limiter on your electric bike. After the chip is installed, your e-bike’s display will show real data, such as maximum and average speeds, daily mileage and cruising range.

How does SpeedBox 2.0 work?

The tuning kit can be activated directly on your bike’s display.  After pressing the WALK button, a value of 9.9 km/h (6.2 mph) is displayed and from now on you will be able to ride at a speed of 40 km/h, 50 km/h and even more than 60 km/h.

To deactivate the tuning kit, press the WALK button again. The value of 2.5 km/h (1.6 mph) will appear on your display and the speed limit will reset to 25 km/h. Your e-bike will then work the same as before installation of the chip.

SpeedBox was also designed for e-bikes that do not have a classic control unit with Walk button. In this case you can just use the combination of + - + -  buttons and SpeedBox will be activated. You can easily deactivate SpeedBox in the same way.


When connecting the SpeedBox chip to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions and videos to make installation easy for you. Disassembly of our 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.

Your Specs say "This product in not compatible with Performance Line CX 2020 motors!" In this discussion there are answers that it will work.
Will this work on Bosch Performance Line CX, 250 Watt (MY20) (New TREK Powerfully 5 2020)


Hi, I have a new (2019) TREK Powerfly 5 with Bosch Performance Line CX motor.
I have exposed the cable blocks for the wiring.
There are 4 connector blocks in a row, but I don't know which ones I should be using.
The connector with 4 cables is obviously correct, but there are three other, each with 2 cables, all of them are 1 black, 1 red.
From left to right they are :-
1. Blue block - 2 cables, 1 red, 1 black.
2. Black block - 4 cables, 1 black,1 yellow, 1 green, 1 red. OK
3. Black block with orange cover - 2 cables, 1 red, 1 black.
4. Grey block with orange cover - 2 cables, 1 red, 1 black.

Out of blocks 1, 3 and 4 can you tell me which one I should use please?

Installed Speedbox 2 on my Cube Steroe Hybrid - Kiox . Fitted with 2019 Bosch CX performance motor . Trying to activate using the Walk button , the Kiox display does not show the 9.9 speed figure you state . It shows kind of count down clock , do I hold the walk button down until the clock counts down to activate ? Try a few different times but Speedbox 2 does not activate ?
What do I need to do ?

Jiří Voldán (Sales Manager)Administrator |

Hi Gordon. Turn off lights (even if you don't have any) and press WALK then. That should help.

I have a bosch active line if I bought this product would I be able to increase my top speed. Ps stay in great Britain

Jiří Voldán (Sales Manager)Administrator |

Hi Sandy. Yes this is exactly what SpeedBox does. We ship worldwide though.


I have just fitted my Speedbox 2 to Bosch Activeline Plus motor and fitting was easy but cramped. Max speeds on a flat are around 24Mph, is this normal?

Jiří Voldán (Sales Manager)Administrator |

Hello James. This is absolutely normal. To reach higher speed you must change a front sprocket for another one with more teeth. SpeedBox allows you to ride faster. Your bike just needs to be equipped that way.
