Last summer, I rode the electric vehicle in which has two wheels such as bicycle.
We called that "전동킥보드".
I rode that once, but it was not good for me.
Because, it looks like very dangerous. =  I have tried to ride a two-wheel electric vehicle that looked like a bicycle. We called it "전동킥보드.". I rode it once, but it was not good for me because it looked very dangerous. Someone says that is so exciting, but it was not for me.
I was nervous during the ride.
So, If = if I have to ride that one more time, I will make sure to wear a helmet.
