What is SpeedBox?
Speedbox is a tuning kit made to derestrict your ebike with Bosch, Yamaha, Shimano, Giant, Brose and other motors. They are made in Czech Republic and are thoroughly tested so they are safe for your ebike motor and battery.
If you wish to remove the speed limit of the electric bike, there is nothing easier than installing a tuning part that removes this speed limit. You can achieve higher speeds, and everything is limited only by the pedalling rate. In our experience, it is possible to ride at a speed of 31 mph (50 km/h) or even more with SpeedBox tuning, and that is already a proper speed! -
How to activate SpeedBox 1.1 tuning kit?
SpeedBox 1.1 tuning kit can be activated on the e-bike’s control unit. After pressing the LIGHT button, the active lights icon will be displayed shortly after which you will be able to ride at a speed of 30 mph (50 km/h).
The kit is deactivated by pressing the LIGHT button again.
When applied, the actual speed will be displayed in half values. The display also shows your trip and other aspects of your ride.

Battery consumption and range
The tuning kit removes the speed limitation of your motor and does not increase the motor power output. It simply removes the speed limiter which cuts the assistance over 16mph (25km/h). What is does is keep the motor assist on until you can no longer pedal any faster due to limitations of bike gearing or leg-work. With the tuning active it is hard to determine the battery consumption since there are many factors involved such as riding style, terrain, cadence, and etc. As a role of thumb, expect the battery drainage to be in the +/-10% range.
-
Is it compatible with SpeedBox app?
No - SpeedBox 1.1 is not compatible with the app.
-
Can I use SpeedBox for an e-bike that measures in miles per hour (mph)?
Of course, you can. When using a SpeedBox to increase the speed of your electric bike, it does not matter whether you measure the speed in km/h or in mph.
-
Does SpeedBox work with a dual-battery bike (an electric bike with two batteries)?
SpeedBox products function with bikes with the original factory dual batteries without any troubles. However, there could be a problem with batteries installed later. E-bikes with additional redesign are not compatible with SpeedBox products.
-
General SpeedBox technical questions
Can I plug in/ out the SpeedBox chip whenever I need?
Of course, the SpeedBox tuning chip can be easily installed in an e-bike by plugging in a few connectors. The assembly and disassembly is therefore very simple without causing any destructive changes.
Recommended settings for derestricting brand new ebike.
If you want to install SpeedBox on a new bike, it is necessary to ride it for at least 1mile (1 km). Before the actual installation, we recommend trying out your e-bike properly and checking how the system functions in a normal operation.
