I'm sure there must be an obvious reason why this isn't already the most popular the most popular conversion to make an ebike, and I just don't know enough about it yet to see it.
Does anyone sell a rear wheel brushless hub motor conversion kit that has an internal geared hub?

I would think a hub motor could be put on one of those just the same as any other hub, right?
It can certainly be done, but I don't know if there's enough demand for such a system. The Puma gear reduction hub motor seems to have gone through several design changes so far without any kind widespread distribution, but hopefully they will get it right soon. If that catches on, it would be natural for a multi speed model to follow...
