Works on literally anything with a handlebar from bicycles to ATVs, but keep in mind they also work great on tubular ATV Racks or Rack Extenders. Fits up to a 1” tube. Great benefit of the handlebar location mount on ATVs is the quick access…..quick draw western style! They also fit on Sportsmans, no Lock & Ride needed. Works great on ATVs that have storage boxes taking up the rack space.
