“Bicycle Sidecar” is, interestingly enough, one of those persistently high search phrases that bring people to Cyclelicious. Happy, Steve Bodiley posted up his build details of a bicycle sidecar with a metal frame and wooden body.
Steve also discusses his experiments and prototypes to come up with his perfect design. He discovers that adding a 3rd wheel to the side of a bicycle changes its dynamics drastically — counter steering, which is the intuitively normal way to steer a two wheeled vehicle, will steer you the wrong way when you add that sidecar! Steve resolved the issue by making the link between the sidecar and the bike a pivot, so the bike can still lean to some extent.
