The wheel arms are what the wheel shaft bearings set on. Most modern
drives in all the links posted are pully to jackshaft then chain to the
wheel. Many with a oil bath chain reduction transfer case in the
system. Chains take a beating and belts save drive trains when the
wheel gets fouled by a snag. Take a closer look in the links at what is
being done and info on systems.

> Hi, Just thought to add this idea to the mix. Instead of wheel
arms, one might use chain & sprocket (newer tech) as in motor cycle.
When I was a kid, I had an old three speed bike with a chain guard that
covered the whole mechanism, I guess that helped keep out the elements
as well as for safety. Thanks, Mike
