Rohloff gear hubs have 14 speeds on the twist shifter.

my new favorite bike , Bike Friday .. that hub , front dyno hub and disc brakes ..
Pocket Llama .. 406_ 20" wheels .

Functionally it is a step through , because the frame tube is Low.

they can built one with Shimano's Alfine 8 speed hub , if you wish.
