Hello all. I have a single speed / fixed gear bike that I am wanting to convert to a 3 speed. I have seen the Sturmy Archer 3 and 5 speed hubs, but I really don't know much about them other than they are internally geared. Are internally geared hubs just as smooth as external gears with derailleur? Like I said, I really know nothing about internally geared hubs.

Another option I am consider is a 2 speed hub and I see that SA also has a 2 speed kick back hub. How does this work? I see there is no shifter for this. Is it a smooth working option? I wish to not use a coaster brake....

Thanks for the help.
