The SpeedBox is manufactured with high quality certified automotive industry components.

Each SpeedBox is tested several times during and after the manufacturing process. Thanks to these high quality standards the SpeedBox comes with a Lifelong warranty. 
The SpeedBox tuning chip comes with original plugs and colour-coded wires for an easy and perfect fit. Installation manuals and videos provide step by step detailed instructions and are easy to follow and understand. The SpeedBox does not require any diagnostic tool for installation. After installation, the tuning is activated by pressing the WALK button, a value of 9,9 km/h (6,2 mph) appears on the display for approx. 3 seconds. This signal confirms that the tuning is activated and that the engine is now fully derestricted for speed up to +99km/h (most likely you will run out of gears before reaching that speed).
The tuning is deactivated by pressing the WALK button, a value of 2.5 km/h (1,6 mph) appears on the display for approx. 3 second. Now, the tuning chip is deactivated and the engine support is reset to its original limitation of 25 km/h.  For Bosch ebikes without a WALK button, there is also the option to switch the SpeedBox ON or OFF by just pressing the + - + - key combination.
NOTE:  If you are planning to install the SpeedBox on a brand-new bike, make sure you ride it for at least 1 -2 km before installing the tuning.

To set the maximum speed, the mode must be changed: Turbo - Sport - Tour - Eco - Tour - Sport - Turbo. The current speed limit is then displayed. To change the current maximum speed, briefly press the WALK button or turn the rear wheel 360°. A displayed speed of 1.5 km/h corresponds to a maximum speed of 15 km/h, a displayed speed of 2.0 km/h corresponds to a maximum speed of 20 km/h, 3.0 km/h in the display corresponds to a maximum speed of 30 km/h etc. If 9.9 km/h is finally displayed, this corresponds to a maximum speed of 99 km/h. After five seconds of inactivity, the last saved limit is saved.
For the 4th generation (MY2020) Bosch engines, you must leave the ebike switched ON after you have finished your ride and until the display shows a constant speed of 0.0 km/h. Within this time the display will show the remaining time in minutes. Then the ebike can be safely parked.
