In recent years, bicycle-related incidents have seen a huge rise, with Secretary of State John Kerry's broken right femur and U2 singer Bono's multiple fractures drawing particular attention. Last week, a cyclist was killed during the morning commute after being hit by A Chevrolet Malibu. The victim was 64-year-old former Navy Seal.

On Tuesday, a study, published in the Journal of the American Medical Association found that the number of bike-related injuries in adults and old people have almost become double from 1998-99 to 2012-2013. The number has gone up from 8,791 to 15,427.

During the study researchers used data from the National Electronic Injury Surveillance System. It included data from around 100 emergency departments, and used the US Census for estimating the incidence for the whole country.

The US has seen a large increase in the numbers of bikers. Tuesday's JAMA study included worrisome details of the consequences of biking.

In the years 1998-99 to 2012-13, head injuries have seen 6% increase by going up from 10 to 16% and torso injuries have increased from 14 to 17%. As per the study, in the most recent years, most of the injuries have taken place on streets. This indicates toward a significant change from previous years when they used to occur on parks, rural areas, or other locations.
