STABILITY AND MANOEUVRABILITY PERFORMANCE OF DIFFERENT TYPES OF BICYCLES. A LITERATURE SURVEY AND AN EXPERIMENTAL STUDY

This report consists of two parts: a survey of earlier investigations concerning bicycles characterized by high-rise handlebars and small wheel diameters and an experiment with 18 twelve-year-old boys in which 6 different bicycles were evaluated with regard to their manoeuvrability and stability performance in a series of ten tests. In the experiment the bicycles used were all currently available on the Swedish market. Three different models distinguished by differences in frame construction, wheel diameter, and wheelbase, and two different handlebar types, one standard and the other high-rise in height, were used. The tests were designed to measure skills similar to those required in actual traffic situations. The results from the experiment showed that bicycles with high-rise handlebars had a worse manoeuvrability performance than bicycles with standard handlebars, affecting both the time expenditure and the number of errors which were committed. The modern rodeo bicycle caused approximately 50% more errors than either of the other bicycle models. The results were supported by interview data from the subjects and by analyses of bicycle accidents from other studies which indicated that bicycles with high-rise handlebars were more dangerous than bicycles with standard handlebars in actual traffic situations. /TRRL/
