No. In general, weight and force are not interchangeable. Weight is a certain type of force, and not all forces are weights.

Force: a push or pull on an object that, when unopposed, will change the motion of that object.

Weight: the force exerted on an object by Earth's gravity.

These statements are correct:

The weight of the cyclist at sea level is 600 Newtons (135 lbf).
The cyclist's peak pedal force is 375 Newtons (84 lbf).
