Abstract

A prospective study of the bicycle spoke injury over a 1-year period included a total of 71 spoke injuries. Of these, 67 injuries occurred on an adult bicycle and four occurred on a child's bicycle. All children sustained ankle and foot injuries, which consisted of contusion and superficial abrasion (N = 45), skin loss (N = 10), skin laceration (N = 4), and undisplaced fractures (N = 12). A biomechanical study was conducted to investigate the use of a protective cover over the wheel to prevent the foot from slipping between the spokes. Wind resistance studies showed that a cover with a mesh size of 10 mm hexagonal could prevent this and at the same time stop the cover from acting as a sail if a flat cover without holes was used instead. The mesh cover, however, will prevent the toes from entering between the spokes but will not prevent the foot from becoming jammed between the wheel and the fork. To prevent this, a plastic shield to bridge the gap between the fork and the horizontal upright has been designed. With these modifications, the bicycle spoke injury can become an injury of the past.
