A novel approach to bicycle design for handling qualities is presented. The design method is introduced through a case study in which a new front-wheel drive recumbent bicycle is developed. Since there exists no proper definition nor assessment for bicycle handling qualities, design process is based on comparing the uncontrolled dynamics of the new concepts to an existing design, known to handl...

Motorcyclists and moped drivers are road users with a particularly high accident risk since motorcycle accidents are severe in nature, due to the relative lack of protection of motorcyclists. Furthermore, given the young age of many victims, these accidents often result in a high-loss of life expectancy for fatalities and high social-economic costs. The ambition of this project is to provide a ...

2 3 The bicycle without a rider balances perfectly well. With a novice rider, it will fall. This is because the novice has the wrong intuitions about balancing and freezes the position of the bicycle so that its own corrective mechanism cannot work freely. Thus learning to ride does not mean learning to balance, it means learning not to unbalance, learning not to interfere.

INTRODUCTION In 2008 the first ever night-time Moto GP Grand Prix was held in Doha following the construction of permanent outdoor lighting, and in doing so establishing the Qatar event as one of the most spectacular on the Moto GP calendar. With an 18-race series visiting 14 countries, four continents and pan-global television coverage, Moto GP is the premier motorcycle racing World Championsh...

Toric origami manifold is a generalization of a symplectic toric manifold: it is a manifold with torus action and a compatible 2-form degenerating in a nice, controllable way. In the same way as symplectic toric manifolds are classified by Delzant polytopes, symplectic toric manifolds are classified by certain collections of Delzant polytopes, called origami templates. We are interested in the ...

It has been argued that driver training can inadvertently result in novice driver overconfidence which may be counterproductive to the safety goals of training. A similar concern can be expressed in regard to novice motorcycle rider training. Overconfidence is posited to generate from trainees’ overestimation of their own skill levels following training, potentially contributing to risk taking ...

Horseback riding is an increasingly popular activity among today's youth, providing them with the opportunity to learn responsibility and respect for animals. However, it can also be associated with severe injury, of which many physicians are unaware. In 2002, there were an estimated 13,400 emergency department visits nationwide for horse-related injuries among children younger than 15 years. W...
