My 5 year old asked me this – Why do all bicycles have the chains on one side only?

Question

I tried answering, maybe something to do with being right handed etc. but nothing really made much sense. So why did we achieve such consistency in bicycle design, while we struggle with other things (metric Vs Imperial, left hand Vs right hand drive cars)?

Answer 1

I would note that metric vs imperial isn’t a struggle: Only around 5% of the world population uses imperial as their primary system. Metric won, and pretty damn hard at that!
