This video reminds of the time my father took the training wheels off my bicycle (I was not ready for the step up to adult cycling), and in my attempts to keep the bike upright and moving, the last thing I remember was him yelling “brake! brake!!!” before I hit a wall.
Well, this is a similar situation though we’re talking a motorcycle not a bicycle, and considering the consequences that could have resulted, the guy comes off with a bloody nose.
And his friend, filming everything, was not yelling “brake”.
It shows that your first motorcycling lessons should be conducted outside, not in an underground carpark with obstacles to get in the way.
Enjoy.
