ride a bicycle with the pedals at rest, especially downhill

the postman came freewheeling down the track

act or proceed in a relaxed or casual way, without making much effort

I'm not the sort of person who would freewheel his way to the end of a contract

another manager might have been willing to freewheel through one final season

a bicycle wheel which is able to revolve freely when no power is being applied to the pedals
