In the bike scene in Nightmare on Elm street part 5.....?

What is going in the bike?....

realistically, would all that stuff happen?...sparks spraying out, steam, the guy/rider being electrocuted.
Every time I see it, it makes me feel sickly in the stomach and slightly disturbed, although I don't know why that is.

I don't know what it is about what I'm seeing that bothers me so much, but I guess that's for another question and section.
*going on inside the bike.
