Peloton’s revenue for the quarter that ended March 31 was $524.6 million—a 66% year-on-year increase and the company’s strongest sales quarter yet. About $420 million came from connected fitness equipment—but that number might have been much higher if Peloton could make bikes as fast as people are panic-buying them.

Peloton financial chief Jill Woodworth said the company entered the fourth quarter with backlogged orders in every region, and that sales continued to surpass expectations. She added Peloton was taking a hit on its profit margins to expedite shipping. In November the company announced it had purchased Tonic, one of its Taiwan-based manufacturers. Yesterday, Peloton president William Lynch told analysts that between Tonic and Rexon, another Taiwan-based manufacturer, Peloton hoped to streamline its bike supply.

Those who do get bikes seem to be actually using them, so Peloton is rapidly changing its digital offerings to account for unforeseen scale. With some 44 million workouts completed in the last quarter, it nearly doubled those completed in the previous quarter.
