Install the latest version of the program (If there are problems with the firmware, use version 1.7).

Model A1/S1/S2 can reach speeds of ~ 30km/h. (MANDATORY AVAILABILITY OF TWO BATTERIES!)

To install the hack, you need to open the program, click "Start scan" and wait for the phone to scan the bluetooch devices around. If the wheel is in the program action field, then you will see it in the list of found devices. To connect to the wheel, click on its name (May take some time).

Next, click the "Get Key, Sn" button, and copy the button against the 3rd key. The keys and serial number necessary for generating a confirmation code are copied to the clipboard. Contact me in a convenient way and send this data.

To change the model, you need to connect to the wheel, press "Get Key, Sn" (point 1 in figure 2 above), wait for the keys and serial number to be counted, enter the code I sent in the code confirmation field (point 3 in figure 2 above), select the model we want to change to, in our case, Turbo (point 4 in the figure 2 above) and press the "Set Model" button (point 5 in the figure 2 above). This will give you a speed limit of 26km / h. To set the limit of 30km / h, you need to upgrade version 7.6.0. select the desired firmware version (point 1 in the figure 3 above), and press the Flash FW button (item 2 in the figure 3 above). Wait for the process to finish and report it (point 3 in figure 3 above). Errors "invalid floating point operation", "Duplicates not allowed." we don’t pay attention, they are associated with rendering the animation. Also in beta version, it happens that the process freezes by 1% and on Start, if you see that the application is frozen, then restart it and repeat the firmware procedure. If this problem still persists, update the version 1.7 of the program (it is in the archive with the beta version, it works longer, but is less problematic. It is better to use the old version for the wheels of this series).

Changing the firmware may lower the security of your device and no one except you is responsible for the actions taken.
