# A Bicycle Can Be Self-Stable Without Gyroscopic or Caster Effects

@article{Kooijman2011ABC, title={A Bicycle Can Be Self-Stable Without Gyroscopic or Caster Effects}, author={Jolien Kooijman and Jacob P. Meijaard and Jim Papadopoulos and Andy Ruina and Arend L. Schwab}, journal={Science}, year={2011}, volume={332}, pages={339 - 342} }

A new bicycle design points to the importance of mass distribution for stability. A riderless bicycle can automatically steer itself so as to recover from falls. The common view is that this self-steering is caused by gyroscopic precession of the front wheel, or by the wheel contact trailing like a caster behind the steer axis. We show that neither effect is necessary for self-stability. Using linearized stability calculations as a guide, we built a bicycle with extra counter-rotating wheels… Expand

The bricycle: a bicycle in zero gravity can be balanced or steered but not both

There is a qualitative difference between bicycles and tricycles, a difference that cannot be met halfway, if the balance problem is removed, by making the system neutrally stable for balance, one cannot simultaneously maintain balance and control the position of the base. Expand

Active lateral stability control for bicycles by steer-assist

- Engineering

Given some forward speed a bicycle can be laterally selfstable [1,2] and therefore needs little rider control to stay upright. However, at low speed the bicycle is laterally unstable and requires… Expand
