We can estimate the global food delivery market to be around $120 billion, taking into account populous countries such as China and India. Now, let's consider the percentage of this market that may depend on bicycles for deliveries: Density and Infrastructure : In areas with high population density and well-developed cycling infrastructure, a larger share of deliveries is likely to be made by bike. Let's assume this represents 70% of the global market, resulting in 70% of $120 billion, which equals $84 billion. Global Bicycle Usage : In numerous urban regions where the layout and infrastructure support cycling, bicycles are often favored for their affordability, speed, and environmental benefits. Therefore, we can estimate that bikes are used for food delivery in approximately 30% of these markets. Thus, the global bike delivery market would be around 30% of $84 billion, which is roughly $25.2 billion.
