 The following query shows you how to group by the field `condition` and apply a reduction based on the previously derived `price_category`. The expression `@price<1000` causes a bicycle to have the price category `1` if its price is lower than 1000 USD. Otherwise, it has the price category `0`. The output is the number of affordable bicycles grouped by price category.
