Forward and opposing forces

Diagram of a cyclist on bike showing forward and opposing forces

Your forward force comes from pushing and pulling on the pedals to make the back tyre push backwards against the road. The two main forces that oppose your motion are aerodynamic drag (air resistance) and rolling resistance of the tyres against the road.
