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

242 views

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)?

Left side drive (lsd) bikes do exist! In the single speed track bike and freestyle bmx space the drivetrain is moved to the other side for aerodynamic reasons and to get it out of the way for grinding tricks.
