iPhone 6 and 5 Mountain Bike Mount for Video, GPS, and All Smartphones This mount is compatible with all iPhone models including iPhone 4, 5, 6, and 6 Plus. Compatible with all smartphone cases also. Grab your mountain bike, and toss your phone onto your handlebars. This mount will fit up to 1.25" circular diameter. Do you want to have your own action camera for a fraction of the price? Action cameras cost about $200 for a quality camera. But why do that when you have a great HD camera sitting in your pocket, your iPhone 6 plus. Equipped with 60FPS, SLO-MO, and even hyperlapse, this is guaranteed to perform better than an action camera. If your mountain bike handlebars are over 1.25", larger standard screw size replacements are available. Ride up the hill, or down the hill, either way, you can fully adjust your angle so you can swivel up and down to wherever you're riding. Whether it's film or GPS, it can swivel to accommodate.
