Paramedics will use cycles carrying life-saving equipment to get to medical emergencies in the city.
The Lifecycle - a cycling paramedic - will now be a permanent response on Yorkshire Ambulance Service's rotas.
Members of a team of eight will work seven days a week. Their bikes carry defibrillators and other kits to give immediate assistance.
The Lifecycle began two years ago as an experiment in York.
It helped stand down 20% of ambulances, freeing them to attend other emergencies.
Every member of the team attends an International Police Mountain Bike Association course on emergency services cycling.
