Add sprocket to scooter hub motor?

[dthames]

I am considering a build to create a very slow moving ride for off road person transport. Speed range would be from slower than a walk to maybe running speed. I was wondering if a chain sprocket could be bolted to a motor hub like this one in place of the brake rotor/disk. The idea would be to build a gear reduced electric drive similar to this.

Thanks in advance for any input.

What is the benefit of adding a sprocket to a hub motor instead of using a motor with a shaft designed for that use?

Since the hub itself rotates via electric power input, what would a sprocket and chain attached to the hub be driving? It would be like an auxillary force output to turn something else in addition to turning the hub that makes the machine roll forward.
Now if the hub was not mounted with a wheel, but instead was just bolted to the frame somewhere, a sprocket attached to it could be used to drive another sprocket attached to the rear axle. The hub would basically take the place of a standard electric motor with a sprocket on it. That would indeed give you the option to choose sprockets that would change the gear ratio to any you wish, but why go that crazy route when a standard electric motor would be so much easier?

In order to have a very slow moving machine, if using a normal shaft motor a gear reduction of 100 to 1 or so might be in order. A hub motor would (under rated output) be turning a slower RPM. Also less noise is desired. The machine would be used for moving in a hunting environment. So avoiding the 1000-4000 RPM output of a shaft motor would be a good thing.
