Mass of man and bicycle = 75 kg
Speed = 7 km/h = 1.94 m/s
Force applied by the man to move at the constant speed = mg Sin 6°
Force required = 75 × 9.8 × 0.104
Force required = 76.44 N
Power = Force × velocity
Power = 76.44 × 1.94
Power output of man = 148.29 Watts
Hence, the power output of the man = 148.29 Watts
