Question: how many calories does a spinning bike burn?
Answer: Biking and Spinning An hour-long bike ride at a leisurely 10 to 12 miles per hour, for example, burns about 256 calories. But crank up your effort to a race pace 16 to 20 mph and you'll torch around 773. A vigorous Spinning class on an indoor bike can burn nearly as many, about 741 calories an hour.
