Regeneration on a bicycle is only possible on hub motors, which usually have a planetary gearset to have acceptable low-end torque, and that gearset has significant drag. Mid-drive bicycles are able to leverage the freewheel, and thus have very high coasting efficiency. You don't really seem to know much about this. It's odd that you seem to have formed strong opinions on said subject. There is fierce competition in the industry for efficiency/range/price...not really sure why you think you can just casually stroll in and go "well DUH, folks, just do..."
