Speed limiter change features (Premium licence)
In most countries, the use of an derestricted bike is possible only in private areas or in specially designated areas. Check the legality of using derestricted bike in your area
For the firmware newer than 4.3.2 [E8000] the best way to rise the Speed Limit is to change the destination market to US (32km/h). This method will maintain the correct odometer and speedometer readings.
The program for Windows is FREE to get information about the bike and change the level of the assistant.
The Premium licence costs 33 USD (~ 30 EURO) excluding VAT
