The following report consists of two parts: a survey of earlier investigations concerning bicycles characterized by extreme handlebars and small wheel diameters and an experiment with 18 twelve-year-old boys in which six different bicycles were evaluated in regard to their maneuverability 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 extreme in height, were used. The tests were performed at ten separate stations and were designed to measure skills similar to those required in actual traffic situations. The experiment was repeated once so that at its conclusion, eighteen subjects had ridden six bicycles at ten test stations twice, for a total of 2,160 trials. The results from the experiment showed that bicycles with extreme handlebars gave a worse maneuverability 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 extreme handlebars were more dangerous than bicycles with standard handlebars in actual traffic situations.
