Anna Niska, a researcher at the National Road and Transport Research Institute, tells the newspaper Svenska Dagbladet that the snowy winter and a higher number of cyclists on the roads have led to more accidents.
"Winter maintenance may not be up to the desired standard," she says. "Speed is also of importance. When people cycle fast, the risk goes up."
Solna municipality north of the city has put up obstacles for cyclists to stop them going fast. Anders Ekegren of the Liberal Party welcomes the initiative.
"Cyclists are in a rush in Sweden. It is a higher tempo, a tougher climate, than in countries like Denmark. Many male cyclists ride in athletic gear and rush down the lanes," Ekegren says.
