Just dropped my MAC motor in to have it re-built into a 26" wheel (was in a 700c) as I've changed bike.
I asked the wheel builder if he thought the same motor (but a higher RPM) would fit into a Brompton 16" wheel, he didn't think so due to the diameter.
Any ideas what the max diameter would be? I was thinking of a Bafang BPM2 48v500 front motor but that's 180 OD too, like the MAC. Might have to go for a Q128?
