Biking does not have to equate to cardio! You can commute to work on an e-bike with your heart rate similar to walking quickly (what I do). And you can go exercise later.

Not sure how these two things got tied together in the common culture. Something I hear all the time is "but you have an electric bike, what's the point, it doesn't get you any exercise" and people saying that commute to work sitting in their cars.
