The concept of a compact planetary gearing system seems awfully familiar!
With the planetary Epicyclic gear system being taken from James Watts 1781 patent.
Just goes to show, technology goes around/comes around. If it works it works - making it lightweight/fragile/expensive/fiddly is not an "improvement". Its just different. And in the case of our trusty fixed wheels, this rings most true.
