Paying for children to be taught cycling proficiency at school is no longer affordable, the Department for Infrastructure (DfI) has said.
The department told BBC News NI that "budget constraints" meant it could not keep paying teachers or instructors to deliver the lessons.
Schools will have to pay teachers themselves if they want to continue the scheme.
The department, however, will continue to provide training.
The cycling proficiency scheme has been running in schools in Northern Ireland for more than 50 years, training more than half a million pupils during that time.
It teaches children who can already ride a bike how to cycle safely, including what to wear, bicycle maintenance and the rules of the road.
