Described in this paper is a Self-Stabilizing Hybrid Bicycle. Gyroscope technology implemented to develop the balancing forces achieve stability on all terrains. The main principle revolves around generating counteracting torque help stabilize tilting action of vehicle. Along with this, we have introduced hybrid system prime cycle when rider tired. includes battery which can be charged by three...

One of the challenging problems with bicycle simulators is to deal with the virtual bicycle dynamics that is coupled with rider’s motion. For the virtual bicycle dynamics calculation and the real time simulation, it is necessary to identify the control inputs from the rider as well as the virtual environments. The steering, pedaling, and braking torques can be easily measured by using torque se...

Lusk et al. claim that American Association of State Highway and Transportation Officials (AASHTO) guidelines discourage " physically separated and bicycle-exclusive paths adjacent to sidewalks. " 1 In fact, these guidelines prohibit bicycle lanes on the roadway separated from travel lanes by parked cars or a raised barrier. They permit bike paths adjacent to the roadway where there is " minima...

INTRODUCTION Bicycling is promoted as a transportation and population health strategy globally. Yet bicycling has low uptake in North America (1%-2% of trips) compared with European bicycling cities (15%-40% of trips) and shows marked sex and age trends. Safety concerns due to collisions with motor vehicles are primary barriers.To attract the broader population to bicycling, many cities are mak...

BACKGROUND In normal subjects treadmill exercise usually produces the greatest maximal oxygen consumption (VO2max). This may not be true for patients with severe chronic obstructive pulmonary disease (COPD) in whom bicycle exercise, which offers support for the shoulder girdle, may produce a higher oxygen consumption than treadmill exercise. The aim of this study was to determine which mode of ...

OBJECTIVE This study aimed to examine trends in the incidence and outcomes of bicycle-related injuries in emergency departments (ED) in South Korea. METHODS We analysed data from the National Emergency Department Information System database for adult patients (≥20 years) with bicycle-related injuries presenting to EDs in South Korea between January 2012 and December 2014. Riders and bicycle p...
