Reports of bicycle-associated accidents collected by the National Electronic Injury Surveillance System (NEISS) run by the Consumer Product Safety Commission are analyzed. These accidents represent a probability sample of such injuries treated in hospital emergency rooms. These data are used to obtain estimates of the national totals of bicycle-associated accidental injuries. Analysis of these data shows that bicycle-associated injuries are highly seasonal, and have increased very slightly with time over the past three and one-half years. A slight increase in the age of persons injured is also noted. The second phase of the analysis deals with 646 in-depth investigations of bicycle accidents. The in-depth reports are restricted to severe injuries. Among these reports, mechanical components of the bicycle are identified as a contributing cause of the accident in about 17% of the cases. The proportion of cases with a mechanical component as a contributing cause is higher for older bicycles than for newer ones, indicating that either newer bicycles are better mechanically, or that maintenance may be implicated in the mechanical failures. The proportion of mechanical causes is also considerably less (8%) for accidents selected from the NEISS than for accidents from all sources.
