1-Power off
2-Push the throttle all the way, and squeeze the brake handle
3-Wait for 2 seconds then power on , you must see a code "E2" flashing, wait 10 seconds then release all
4-New full-throttle speed 24km/hour unlocked
okay....but cannot use on public area.
So, quick question. What throttle? I'm not seeing one on the manual of mine.
