I got the itch to buy another motor. I was going to buy the Edge 1500W from LAebikes, but I already got the MXUS 3000W V2 and the Leaf/Edge are close in diameter to the MXUS.
MXUS spoke-hole flange diameter of 231mm (9.1") (spoke Pitch Circle Diameter / PCD)
For some reason I got the geared MXUS XF07 in my mind. Quick search reveals this,

One of the most strongest geared hubs known are Mxus XF07

Reading that last quote, I just had a vision. You know how some bicycle riders have that sticker that says CAR FREE or something. Sometimes they put a cardboard sign in their spokes. I have even seen some where it covers the entire wheel.The strongest geared drive by far is the MAC 500w.............
............A direct drive motor would be 5-10% more efficient at cruising speed and nearly dead silent running, but nothing on the market could be hidden. it's going to be obvious you have something huge in your wheel. The Old Crystalyte 408 series motors were smaller and even quieter, but they aren't sold anymore.
