Sidecar Bike – How does it work?

A sidecar bike is a great way of extending the capabilities of your bicycle. By having a sidecar, you can easily transport cargo that is simply too large for panniers and racks. But have you ever wondered how a sidecar bike works? It seems like a miracle that it is able to stay attached without causing the bike to tip over. However, there are two simple methods which are used to keep everything balanced- sidecar lead, and toe-in. In this article, we’ll explain just how a sidecar bike works, so you won’t be left wondering anymore.

The “sidecar lead” refers to the horizontal distance between the rear wheel of the bike, and the rear wheel of the sidecar. The greater this distance, the less of a risk there is of the bike and sidecar tipping over. However, a bigger sidecar lead will also cause the sidecar’s tires to wear out more quickly, so it’s important to get the sidecar lead just right.

The other way that a sidecar bike stays balanced is known as “toe in”. The weight of the sidecar means that the bike will be constantly pulled towards it- something that could pose a big problem if it isn’t dealt with. To counteract this, the sidecar will typically be tilted slightly towards the bike itself. The bigger the sidecar, the more toe in is required, both due to the increased weight and because of the wind resistance that could knock the bike off balance.

As you can see, it requires a lot of skill to get the balance just right. We’ve worked hard to ensure that every measurement on our sidecar bikes is just right, so that you can be sure of a safe journey, every time.
