Many people often wonder how much difference there is when riding bikes with large and small wheels. Compact folding bikes save space but require more effort to pedal and are not as easily capable of achieving high speeds. On the other hand, road bikes with larger wheels are often associated with greater momentum and the ability to cover longer distances. But how much of a difference is there in reality? Jollymap will conduct a simple test to provide an answer. We will perform a test where the bike is pushed down a slope without pedaling, allowing it to roll naturally, and observe the differences in rolling distances among bikes with different wheel sizes. Although this test is not highly scientific, as wheel sizes are not the only factor, each bike has its own design, specifications, and maintenance. Additionally, the road surface may not be perfectly even, with some slight variations in elevation. Nevertheless, this test will provide an overall understanding of the differences in inertia between different wheel sizes. And most importantly... it's all for fun, staying true to the spirit of "taking trivial matters seriously" in this case.
