What weird thoughts some people have!

A single speed (with freewheel/freehub) bike makes a lot of sense for commuting, especially longer distances. It is simpler, lighter and easier to maintain than a geared bike and when function is more important than form, coasting is something rather nice not to lose.

FG (or any) cyclists who sneer or look down at someone else's bike have forgotten that the joy of cycling is not about looking cool.

Regards.
