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
Optimal control of a Two-Mass Skate bicycle without steering
Until recently it was believed that the ability of riderless bicycles to remain upright derives from a combination of the gyroscopic precession of the front wheel and the trail designed into theExpand
Analysis of stability differences in road and time trial bicycles with instantaneous and delayed control
Bicycle stability has been of interest to dynamicists and athletes since before J. W. Whipple described the canonical model for bicycle motion in 1899. Since then, the subject has fascinated many whoExpand
Balance and control of a rear-wheel steered speed-record recumbent bicycle
The goal of the Human Power Team from the TU Delft and the Free University of Amsterdam is to break the world speed record in unpaced cycling (Sam Whittingham, 133.28 km/h). The design of such aExpand
The bricycle: a bicycle in zero gravity can be balanced or steered but not both
TLDR
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
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 requiresExpand
Parametric analysis of the stability of a bicycle taking into account geometrical, mass and compliance properties
Some studies of bicycle dynamics have applied the Whipple Carvallo bicycle model (WCBM) for the stability analysis. The WCBM is limited, since structural elements are assumed to be rigid bodies. InExpand
Design and implementation of a steer-by-wire bicycle
TLDR
The purpose of the steer-by-wire bicycle is to investigate the influence of handlebar torque feedback on rider control in order to understand rider control on a bicycle. Expand
Dynamics and Control of a Steer-by-Wire Bicycle
This work is focused on the modeling and experimental validation of a steer-by-wire system for bicycles. The purpose for this system is to modify and enhance the lateral stability of a bicycle at lowExpand

Rider control identification in bicycling using lateral force perturbation tests
A model describing rider control while steering and stabilizing a bicycle has been developed. Experimental data were obtained from riding a bicycle on a narrow treadmill while perturbing balance withExpand
