Character mistake: The leader of the Purple Knights says that they would only be bike riders if they couldn't tell which gender someone was by their hair. This is a major mistake, because if you look at the hair of the Purple Knights, it's incredibly easy to tell which gender someone is.
Visible crew/equipment: In the motorcycle joust sequence, when the Purple Knight falls off his bicycle, his helmet flips up and you can see it's a stunt double - the Purple Knight's beard is gone.
Revealing mistake: At the start, when Max falls off his police motor cycle, he is obviously a stunt double.
Visible crew/equipment: Lights are reflected in the aide's glasses when Max and 99 are talking to him on the ground.
Revealing mistake: When the Prime Minister's aide falls out of the car, he is a dummy.
Audio problem: During the joust scene, Max turns around to have another charge at the Knight and the crowd is clapping, but there's no sound at all.
Continuity mistake: During the joust scene, several tyre marks on the ground from the motorcycles disappear from the ground.
Other mistake: The same shot of Max charging on his motorcycle is used twice in less than a minute.
Audio problem: When Max is freed from the chains and punches the biker, he misses the punch completely, but the guy falls over.
