If you purchase a bicycle shipped from a factory in China, it typically takes 3-5 days for production, assembly, and testing before shipping. Shipping time depends on the country of origin. If you purchase a bicycle shipped from a warehouse in the United States, it can be shipped within 24 hours, and arrival in the US takes only 5-7 days.
