You're acting like these Walmart bikes with 1200w motors are commonplace, and sold in mass quantities. Most people aren't going to spend their time fitting this stuff on a regular-ass bike. These "kits" don't even bolt onto most bikes, and require some ingenuity to make them fit. What I'm saying is there's not enough of them out there for people to ever care about the issues you bring up.
