1. Please sell me whatever drugs you do. Batteries have a much lower energy density to gas, for starters. Batteries + electric motor is going to be heavier than a half-full gas tank + gas engine with the same performance

I have been thinking about doing something like this for a while.
My main options were something like this BB mounted motor and a battery pack that goes in the triangle.

You would have to figure out what chainring will clear the frame or modify to fit, but I beleive with one of these setups 35-40mph is easily obtainable and seems to bewithin your budget.
PS: the bike will be well of 50lbs.
