A bicycle wheel hub includes a driver rotatable about an axis at a first rotational speed, wherein the driver includes a mating feature configured to engage a cassette. A shell is rotatable about the axis at a second rotational speed. A non-adjustable gear train is coupled between the driver and the shell, wherein the gear train defines a single fixed gear ratio greater than 1:1 between the driver and the shell. A bicycle drive train includes a drive unit having a user input component rotatable about a first axis at a first rotational speed, a chain ring rotatable about a second axis at a second rotational speed, and a gear train coupled between the user input component and the chain ring. The gear train defines a gear ratio less than 1:1 between the user input component and the chain ring. A method of propelling a bicycle is also provided.
