Arkon Bike or Motorcycle Handlebar Strap Mount with AMPS Head for Satellite Radios

It's equally at home holding mobile radio cradles, housings and similar gear. Once an industry standard, the 4-Hole AMPS pattern uses four holes arranged in a rectangle measuring 30.17mm by 38.05mm, taken centre-to-centre between the holes. Supplied here is Arkon's Bicycle or Motorcycle Handlebar Strap Mount on its own, with holders sold separately. The strap clamps onto handlebars and roll bars anywhere from 15mm to 50mm in diameter, and because it uses a zip-tie style design you won't need any tools to fit it. A swivel ball adapter head turns a full 360°, so you can dial the device in to whatever viewing angle suits. Running a Garmin GPS instead? Simply unscrew the swivel ball adapter to expose the 17mm ball mount base underneath.
