If 100KM, means there is no limited for speed setting, however, the speed limited setting is
controlled by motor and controller. You can only set the bike computer speed limit with the
range of limit motor and controller. For example, if the motor and controller speed limit is at
40KM/H, you can only set up lower top limit such as 35KM/H, If you set 50KM/H, the real top
limit is also only 40KM/H;
