What makes a bike stay upright when it is in motion? What is the relationship between speed and stability? Is it a linear relationship? I could ask this on the physics site however I am hoping for a relatively simple answer. I took an…

If you are biking on level ground with no wind, I understand that there are losses inherent in your activity which you provide effort to overcome (if you want to maintain a steady speed): Air/wind resistance Rolling resistance Friction losses ? I…

This may get too math-heavy, but it seems that only a few variables are needed to estimate the optimum slope to descend without gaining/losing speed. I looked around, but wasn't able to find anything directly relevant- just discussions about drag at…

I'm less interested in the empirical answer to this question and more interested in the theoretical physical dynamics that govern this. I understand that the rider applies some force to the pedals (which could also be thought of as a torque given…
