If you have ever worked with a well seasoned bike mechanic, they will often refer to FSA parts as;
“FSA” short for “Faulty Shifting Apparatus.”
Not true! for their urban Metropolis line made exclusively in Taiwan. A very cool line up of a custom stem, a cool handlebar, and a few specialized cranksets.
The Metropolis Planetary Transmission is a freewheeling crankset that is equipped with 2 internalized gears all hidden within the front crank.

I have always considered a front derailleur to be primitive technology and take them off my city bikes (motorized or not.) Many people always debate over how many speeds a good e-bike should have. This next generation front 2 speed drivetrain option could prove to the holy grail for e-bikes.
Imagine taking a 7 speed or 8 speed e-bike hub motor coupling it with the Metropolis Planetary Transmission and now you would have a clean 14~16 speed e-bike. Clean, lightweight, and slightly techie for the e-bike crowd.
Available in bike chain or Gates center track belt versions. The sales rep said it can not be used in a fixed gear type application.
