My guess? They aren't. It's just an oversized bearing. Could also be a geared hub, which wouldn't necessarily require a bearing right next to the drop.

Anyway...I actually made a halfassed attempt at water cooling a hub motor. Was some abomination involving some sheet metal with holes drilled in them that covered a bunch of the casting and a whole bunch of silicone caulk. I ground a slot in the shaft just big enough to pass the tube through. Never actually got around to testing the thing.
