Samenvatting
The 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 manoeuvrability and stability performance. The results from the experiment showed that bicycles with extreme handlebars gave 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.
