Linearized dynamics equations for the balance and steer of a bicycle: a benchmark and review
We present canonical linearized equations of motion for the Whipple bicycle model consisting of four rigid laterally symmetric ideally hinged parts: two wheels, a frame and a front assembly. TheExpand
Basin of Attraction of the Simplest Walking Model
It is shown that the basin of attraction is not directly related to the stability of the cyclic motion, and a general method for deriving the equations of motion and impact equations for the analysis of multibody systems, as in walking models is presented. Expand
Benchmark results on the linearized equations of motion of an uncontrolled bicycle
In this paper we present the linearized equations of motion for a bicycle as, a benchmark The results obtained by pencil-and-paper and two programs are compaied The bicycle model we consider hereExpand
A Bicycle Can Be Self-Stable Without Gyroscopic or Caster Effects
This work built a bicycle with extra counter-rotating wheels (canceling the wheel spin angular momentum) and with its front-wheel ground-contact forward of the steer axis (making the trailing distance negative) and shows that various design variables, like the front mass location and the steeraxis tilt, contribute to stability in complex interacting ways.

The influence of the biarticularity of the gastrocnemius muscle on vertical-jumping achievement.
The hypothesis formulated by Bobbert was substantiated, although quantitatively the effect is small, and it was shown that the results described by these authors can be explained from the moment-arm-joint-angle relation of GAS at the knee in their model. Expand
Rider motion identification during normal bicycling by means of principal component analysis
Recent observations of a bicyclist riding through town and on a treadmill show that the rider uses the upper body very little when performing normal maneuvers and that the bicyclist may, in fact,Expand
Linearized equations for an extended bicycle model
The linearized equations of motion for a bicycle of the usual construction travelling straight ahead on a level surface have been the subject of several previous studies [1], [2]. In the simplestExpand
The safety of electrically assisted bicycles compared to classic bicycles.
Electric bicycle users are more likely to be involved in a crash that requires treatment at an emergency department due to a crash than classic bicycle users, and policies to minimize the risk and maximize the health benefits for users of electric bicycles are advised. Expand
How to keep from falling forward: elementary swing leg action for passive dynamic walkers
Stability control for walking bipeds has been considered a complex task. Even two-dimensional fore-aft stability in dynamic walking appears to be difficult to achieve. In this paper we prove theExpand
Experimental validation of a model of an uncontrolled bicycle
Abstract In this paper, an experimental validation of some modelling aspects of an uncontrolled bicycle is presented. In numerical models, many physical aspects of the real bicycle are consideredExpand
