The effect of exercise (training stress, if you want to be technical) is basically effort multiplied by time. If you exert the same effort for a shorter time, you'll have less exercise effect. If you exert less effort for the same time, you'll have less exercise effect. You're getting help (that's the whole point of these things, right?), and so you're not getting "the same benefit of the exercise."
ill grant you per instance of biking its not the same as a regular ride, but if it allows you to use the car less and exercise more then the benefits are still there. and nothing stops you from going all out and training hard, you just move through space faster
