A smart chip of the third generation with an option to set a speed limit of an e-bike.

SpeedBox 3.0 tuning chip enables to select speed limit of your own choice. 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 3.0 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.

You can set the maximum speed of an electric assistance by changing modes: Turbo - EMTB - Tour - Eco - Tour - EMTB - Turbo. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by pressing WALK button shortly or by turning the rear wheel 360°. The value of 1,5 km/h on the display corresponds with the limit of 15 km/h, 2 km/h corresponds with the limit of 20 km/h, 2,5 corresponds with 25 km/h, 3,0 corresponds with 30 km/h, 9,9 corresponds with 99 km/h etc. The last displayed limit will be saved after 5 seconds of inactivity.

When using SpeedBox 3.0 with Bosch motors of the 4th generation (produced in 2020 or later) it is necessary to leave the bike on after finishing the ride until a value of 0.0 km/h is displayed. During this process the remaining time will be displayed in minutes. Then it is safe to turn off your bike and you can start looking forward to your next trip.


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.

How long until the countdown starts once the bike stops.?
Will it start if the bike stops for just a few seconds waiting for traffic etc.?
Once the countdown has started will the motor work immediately again?
I don't want to have no power to move off just because I stopped for a few seconds and the countdown kicks in.


Hi. Installed and it works well. Can get the bike up to 45-50 km now --- run out of gears after that :-[ --- One thing that I've noticed though is that it seems it isn't working when I'm going uphills. It slows down to the 'normal' speed assistance (25km/h) when going uphill.
I installed it on a Bosch Active Line 2019 - Scott Subcross eride 30.

Has anyone else experienced this? Maybe I installed it incorrectly (is that even possible)?

Mr. Jiří Voldán, could you shed some light on this please?

Thank you!


Received mine Speedbox 3.0 today.
In an email reply to me, the sales manager for speedbox said that 'never heard of any issues such as motor seizure/not repaonding nor battery failure (not recharging). Will let you know how it goes.
I'm installing it in a bosch purion 2019 system



I have the speedbox 3 on a gen 4 bike and it works perfectly!

I have the same question as RichG. What happens if you turn of the bike before the countdown is over or if you put the charger in before the countdown is done?

Looking forward to your reply

Jiří Voldán (Sales Manager)Administrator |

Thanks for your positive feedback. Don't worry though, nothing happens. If you accidentaly did not let the countdown reach 0, you'll be required to do it when you turn your bike on again. Feel free to test it. However, please don't ignore the countdown. There is just one simple rule, let your bike turn off itself after a ride.


Hi, I have a mustache samedi 27 off 6 and have installed the newest update. Does this product work then?

Jiří Voldán (Sales Manager)Administrator |
