Low Power All-In-One?

[kudos]

Does anyone know of any small low-power all-in-one motors available?

Something with the battery and controller inside the motor?

There are a few all-in-one's, but they all appear to be larger or more powerful than I would like.

Looking for something stealthy that can fit behind a disc rotor.

That would probably be an *extremely* tiny battery to fit all that in one hub smaller than a disc rotor (even a 200mm rotor is pretty small diameter; is yours that large or is it a 180 or 160, or something else?).

How much assist do you need it to do for you, under what conditions?

Note that anything with a battery, controller, and motor inside the same casing, especially an uncoupled casing like a hub in a wheel, may have a hard time shedding heat, and may degrade the battery faster than if it were not in there. This also applies to controller parts (especially electrolytic capacitors).

Can you link to the systems that do *not* meet your needs, so we know which ones not to suggest?

You're right about the battery size being very small, I was thinking of something which I now realise has opposing technical requirements.

I think I'm going to have to scratch this idea.
