Overall, sales fluctuated significantly over the period, with the highest figure recorded in January and the lowest in June. Notably, February saw a dramatic decline, and sales failed to recover thereafter.
In January, the shop sold 50 bicycles, but this figure plummeted by 20 in February, dropping to 30. Sales continued to fall in March, reaching 20, before stabilizing at this level in April. By May, there was a slight increase to 30, but in June, sales dropped sharply to zero.
The erratic trend suggests external factors such as seasonal demand or supply issues. The complete cessation of sales in June is particularly striking and may reflect a seasonal closure or inventory shortage.
