Probably the 8 speed internal gear hub is the most valuable piece on this thing. If it's shimano, it's probably worth 300 bucks.
But this bike per se is probably worth 80 bucks.
I doublt you will be able to install a middrive electric motor afterwards. Even if you would have the knowledge, NOT WITH A HUB MOTOR. That hub will die in 1 week.
