Since bikes are a small part of the battery market, nobody is developing batteries for bikes. The bike industry probably benefits from the development of cells for cars and possibly computers, but those technologies are already fairly mature. Cars use large numbers of small cells. As with disposable batteries, the industry will probably settle on a small number of cell sizes.
Mechanisms and controls will probably evolve like conventional bike components, where one or two manufacturers produce the innards for everybody.
the fat tire bikes tend to be the cheap ones bought over the internet. upright so they fit everyone with a hub motor. myself my battery is only partly integrated as it cost less and is easier to remove and it fits my tandem bike too. but the better bikes use cells used in cars now. well most do but lower quality cells. e bikes for the most part only use one size of cell the number of them is what's different.
