Your e-bike display will show a value of 3.5 km\/h (2.2 mph) and from now on you will be able to ride up to 35 km\/h. You may change the default speed limit to any limit you want (up to 99 kph), however, to minimize the risk of error codes, we recommend not to exceed 35 km\/h.\u003c\/p\u003e\n\u003cp\u003eTo deactivate the tuning, activate the WALK assist function shortly again (by holding down the “-” button). Your e-bike display will show a value of 2.5 km\/h (1.6 mph) and the speed limit will be reset to 25 km\/h. Your e-bike will then work the same as before the tuning installation.\u003c\/p\u003e\n\u003cp\u003eSpeedBox was also designed for e-bikes that do not have the WALK assist function enabled, or activated. In this case, you can activate\/deactivate tuning by switching between two assistance modes twice, i.e. by pressing the - + - + buttons.\u003c\/p\u003e\n\u003cp\u003eYou can set the maximum speed limit by switching the modes from TURBO mode three levels down and then three levels up: 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 activating WALK assist function shortly or by turning the rear wheel 360°. The value of 2.5 km\/h on the display corresponds with the limit of 25 km\/h, 3.0 corresponds with 30 km\/h, 3.5 corresponds with 35 km\/h etc. The last displayed limit will be saved after 15 seconds of inactivity.\u003c\/p\u003e\n\u003cp\u003eAfter finishing the ride, leave the bike on until a value of 0.0 km\/h is displayed. During this process the remaining time will be displayed. Then it is safe to turn off your bike and you can start looking forward to your next trip. Do not remove the display to lock the e-bike until SpeedBox finishes the \"countdown\" process.\u003c\/p\u003e\n\u003cp\u003eAssembly\u003cbr\u003eWe use original connectors for the production of SpeedBox products ensuring that the installation process is very simple and the SpeedBox is connected properly. We have also prepared detailed instructions and videos to make installation easy for you. Disassembly of the SpeedBox is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us.\u003c\/p\u003e\n\u003cp\u003eIf you are planning to install SpeedBox on a brand-new bike, make sure you ride it for at least 10 km before the tuning is activated.\u003c\/p\u003e\n\u003cp\u003eImportant:\u003cbr\u003eConnect the male - female connectors in the direction of the lock.
