If I had a friend who was adamant about a road bike, I would install a TSDZ2 mid drive. It fits into where you have your cranks and you lose the front derailleur. However, you just pedal it and the motor will spin at a rate proportional to your effort, It comes with a throttle which doesn't have to be used and the motor stops when pedal force halts, About $400-500 for motor. Battery will be $500 and up.
If you're not far from Northern Illinois, talk to this man, I've never met him, but his shop sound very reputable.

I have just installed a TSDZ2 mid-drive on a bike intended, and used, for commuting and errands. It is great. Much more than the Bafang, with rotation sensors, it feels like a normal bike, just a bit more responsive. I am definitely getting my heart rate up, but it is easier to ride.
As far as the install, It was pretty easy. I did install it on a bike with cheap Shimano hydraulic disc brakes and they are more than adequate.
