Bicycle Rider Control: a Balancing Act

A case of bilateral testicular calcifications in a bicycle motocross rider accompanied by bulbar urethral injury.

A 21-year-old Japanese man who was a professional bicycle motocross rider injured his perineum during a competition. Chief complaints were gross hematuria, perineal pain, and subcutaneous ecchymosis of the scrotum. Urethrocystography revealed a torn bulbar urethra and extravasation in the same region. Scrotal ultrasonography revealed small calcifications in the bilateral testes. Here, we report...

Motion Analysis of Horse-Rider for Coaching System

This paper construct a database of the national representative level of a professional horse-rider by wearing a motion-capture suit attached with 16 inertial sensors under an inertial sensor-based wireless network environment, then make a visual comparative analysis on the values of all motion features (elbow angle, knee angle, knee-elbow distance, backbone angle and hip position) classified de...

Biking Without Pedaling

It is well known that skilled bicycle riders can balance and propel themselves forward using motions of the handlebar. We present the complete nonlinear dynamics and control of such a pedal-less bicycle with a rider. Propulsion is achieved not by pedaling but by a cyclic motion of the steering axis of the bicycle. It is shown that this kind of actuation results in net forward motion of the bicy...

Motorcycle rider training.

Motorcycle riding is an accessible and cheap form of transport for many people worldwide, particularly in low and middle income countries where other forms of private transport are not affordable. Motorcycle riders, however, account for a relatively high proportion of road traffic-related fatalities and injuries in such countries. The lack of experience of many motorcycle riders has been cited ...
