In the United States, the rate of bicycle accidents has declined over the last three decades, but that trend is being reversed in Europe.
In Europe, bicycle accidents have risen by 20% in the past 15 years, according to a study released this week.
The study is based on data from the European Union’s Breda study of bicycle-related deaths, which surveyed more than 1.4 million people.
A majority of the cyclists surveyed, 63%, said they were at least slightly injured on a bike.
Only one in 10 cyclists said they sustained minor injuries.
The researchers attributed the rise in injuries to the introduction of more dangerous and sophisticated technology, such as the bicycle-riding helmet, which reduces the risk of a collision by reducing the amount of space between the rider’s helmet and the bicycle.
The helmets, however, can be expensive, and they are not available in many European countries.
The average cost of a helmet in Europe is around $40.
A European cyclist can expect to spend $1,300 on a helmet, according the study.
“The cost of the helmet has increased significantly in recent years and has made the helmets more expensive,” the study says.
“In many European nations, the average cost is about $150, whereas in the United Kingdom, the helmet cost is less than $25.”
In recent years, cycling has become more attractive for young people.
According to a recent report by the American Cyclists Association, cycling is now the fastest-growing leisure activity for people between the ages of 18 and 35 in the US.
Cycling is also growing in popularity among young people in Europe, according a recent study from the Institute of Economic Affairs at the University of Amsterdam.
Cyclists in Europe are increasingly looking to other forms of transportation, such an electric bike, and are using a range of other methods to get to work, the report says.
Cyclist deaths are also up in Europe compared to other parts of the world.
According the International Cycling Union, cyclist deaths in Europe rose by 10% between 2006 and 2012.
The report says that in 2012, cyclists in Europe were involved in more than 2,600 bicycle-involved accidents.
Cycling accidents have also increased in the U.K. and France since 2000.
According a 2012 study from London-based Transport for London, cyclists are more likely to be injured on the road, with the majority of cycling-related injuries resulting from being struck by a car, falling, being struck from behind or being hit by a cyclist’s bike.
