Bicycle dynamics


A bicycle is a single tack vehicle. The idea with it is that it has motions that are more difficult when compared to something with more wheels. It’s hard to figure out exactly what the bicycle dynamics do and how everything impacts this process in a meaningful manner. The bicycles lack lateral stability when they are stationary, and that’s obviously going to be quite the issue in that perspective.

The reason why a bike stays upright when it’s steered is that it helps maintain the center of the mass over the wheels. Otherwise it will result in a few problems and you really want to avoid that. The steering process is controlled by the rider or even by the bike itself at some point, depending on the situation.

You will notice that there are multiple factors like gyroscopic effects, mass geometry and distribution that contribute to the overall stability. If anything goes wrong here, the bike stability will hinder and you will have quite a lot of issues in that perspective.

What you have to realize is that a bike needs to lean in order to maintain good balance in a turn. Usually you will need more leaning when the speed is very large or the turn radius is very small. All the little details matter when it comes to something like this, so you really have to study everything to avoid any potential problems that might appear in such a situation.

By leaning, you get to balance the roll torque, something that usually appear as a result of the gravitational; force. The lean is produced by the idea of steering into the other direction to give control, and that’s countersteering.

It’s important to note that this approach is required by the procedural memory, it’s not something conscious most of the time. Yet the primary control input is not the position, it’s the steering torque, and that’s a very important aspect that you have to consider all the time.

Aside from these, there are some other things like suspension, vibration as well as longitudinal dynamics that all play a major role when it comes to how bicycle work. The idea is to know exactly what approach you need to use here and adapt that to your own needs. It’s definitely not something simple to do, but it can totally do wonders as long as you know how to counteract any motion and maintain balance.

While the bicycle balance is delicate and sometimes challenging, it’s safe to say that results will be very interesting. You should totally consider what the challenges are and what you want or dislike, and that will help you a lot.

Overall, even if the bicycle dynamics vary from one model to the other, the main principles remain the same. You really have to take that into account, and the outcome can indeed shine in that situation. You just have to choose the right bike for you and the overall results will be more than impressive!
