I have considered an e-bike, but I may hold off for now since they are expensive as heck, both to build or to buy. I am starting a new job soon that makes using the bikes as transport to save money a bit more difficult due to the distance and the routes available to me, so for now they are just a hobby anyway. 12 miles of city riding is a bit more than I want to deal with for a commute on a bicycle of any kind.

Enlighten me on this dual pull single brake lever? Funny enough when i was looking into the two ideas i was actually saving money going Ebike. This was based off of the idea of buying a new bike from Ctire here as the base. Granted a cheap one with rim brakes to upgrade around the motor later kind of thing. But at this point there is also a plan i found on a site to build a cargo type bike that i may consider for the ebike idea. Modify the plans a touch to have a staggered tire set up similar to a dirt bike and have the smaller rear being a hub drive as i keep finding 24" hub drive wheels for reasonable prices. The goal there would eventually be to have a 2wd Ebike kind of set up like a Dual sport motorcycle. I would be taking advantage of the stretched wheelbase of the cargo bike to have somewhere to place the batteries in a lower center of gravity location.

Dual pull lever is just what it sounds like. One lever that pulls both the front and back brakes at the same time. Usually this is done because the left hand has to also operate the clutch for the engine. It's not ideal, and I am not a fan of it because you lose control of adjusting the brake bias on the fly, but for a purely road going machine it works ok.

One example of the type of lever. https://www.amazon.com/Sunlite-Alloy...a-335204177758

That dual drive cargo bike idea sounds interesting. I always thought those cargo bikes could have some serious range and a powerful motor on them due to how they are laid out.
