Yes it can but it is a bit more complicated then that. The motor that is rated at 100 Watts will draw 100 watts electrical power, but will only output 70-80% of that in mechanical power. So in order to get 100 watts back out you would have to put in ~120 watts of mechanical power to get 100 watts electrical back out.
One would average about 100 Watts. Money and walk away with a penny). You can earn about $0.01 U.S. Dollars per hour using a pedal power generator.
