re: Loctite tape
If it was my money and I was asked to build a new bike for light commuting, no hills, no heavy payload (like a trailer)
the rear hub drive would be preferable.
However, if you're after a drive-train to handle heavy loads, hills, high speeds, offer higher efficiency, better handling
then mid-drive gets the nod.
I agree, I would only recommend a hub for very basic, flat riding. The extra weight in the wheel affects handling and you will go through spokes and rims quicker. No hub on the market can match the efficiency of a mid-drive in hilly areas. There is a reason why all high end $4000+ ebikes are using mid-drive systems. They get much better range out of the 400wh/500wh packs offered.
Rental bikes may prefer front hubs because they are generally a charge and forget about it scenario. They can get enough range for someone to cruise around for a few hours.
16Ah in a frame pack will be a possibility very soon with high discharge 3400mAh/3500mAh 18650 cells becoming available. The money being poured into developing these cells by Sanyo/Panasonic/Sony/LG/Samsung is amazing.
