Cycling teams have announced plans to wear black ribbons at their next races after the shocking death of 17-year-old Jan Riedmann, a German rider who died from head injuries after a collision with a car during a training ride.

Leading figures from professional team Bora-Hansgrove have spoken of their anguish after the teenager was hit by a car while traveling at high speed from Ullstadt towards Sugenheim, where the vehicle took right of way as Riedmann trained with his teammates.

The teenager is said to have crashed “almost unchecked” with the 58-year-old driver, suffering “severe” head injuries despite wearing a helmet, according to BR24.

A rescue helicopter immediately flew the member of the under-19s team to a university hospital in Wurzburg but doctors were unable to save him.

It is with great sadness that we say goodbye to Jan Riedmann, a rider from our U19 squad, Team Auto Eder Bayern, after a tragic accident this weekend. Our sincere condolences to Jan’s family & friends.In honour of Jan, our riders will wear ribbons at Milan-San Remo.
