Depends on how fast you want to ride .
Me , I have geared bikes for “ bike rides”
For Cruising, I like the simplicity of a single speed bike .
I gear my SS bikes to handle the hills around my areas . But I spin out around 7-10mph , depending on bike .
it’s called cruising . I’m not racing anybody .
if I want gears, I go with a derailleur. Simple , easy for me , to work on .
