Please note that this modification may void your warranty!
Before starting, please review the whole process, you may need a friend holding some parts.
Remove the bolts from the bell and the brake lever
Remove the cover above the headlight
Remove the two bolts holding the headlight
Remove the 3 bolts holding the handlebar
Move the brake leaver a little to the end of the bar. Then move the ring. Then move the rubber holding the wire. Repeat these steps 5+ times to reach the end of the bar. Do not use a lot of force, because you may disconnect the wire from the chip!
Remove the bar end-cap and then the brake lever should pop out
Screw the 2 bolts holding the headlight
As result, the folded scooter may be a little bit more twisted, but there are no issues.
