Morphology
fixed-gear + drivetrain
The noun phrase is compositionally built: 'fixed-gear' modifies 'drivetrain', so a learner who understands 'fixed', 'gear' and 'drivetrain' can infer it denotes a drivetrain that uses a fixed gear. However, the crucial mechanical consequence (no freewheel and the need to keep pedalling) is technical and not fully predictable from the simple constituent meanings, so full comprehension requires domain knowledge.
Etymology
Fixed-gear drivetrain comes from the simple, literal setup: a fixed gear is attached straight to the drivetrain, so the pedals and the rear wheel turn together. So you cannot 'coast' and must keep pedalling whenever the bike is moving.
