You have to actually be paying attention to the ground when you ride those scooters. They are light as hell and people be riding them without paying attention to potholes or cracks on the sidewalk or little dips. I ride these bytches all the time cause they fun. And by law supposed to ride them in the street, not on the sidewalk. But most people too scared to ride in the street. Even when you see bike lanes nikkas will be too scared to ride in the street.
To sum it up, basically he too p*ssy and his awareness level too low to be riding the scooter. That’s why he crashed and hurt himself
