The RoadVise is a solid mount solution that's perfect for your needs. It features a spring-loaded mechanism that expands to securely hold smartphones with cases up to 4'' wide. Arkon recommends only using the RoadVise Holder on phones using protective skins or ruggedized cases. The RoadVise is designed to use two hands to install and remove your device. This is to make sure your device cannot be accidentally removed while adjusting viewing angle. The mount's solid construction provides strength and reliability on the road. The low-profile RoadVise holder keeps rear smartphone cameras free for spontaneous pictures or videos and is easy to install. Just snap it onto the 17mm ball of the pedestal and use the included tightening ring to secure. The zip-tie style design requires no tools to install. The bike/motorcycle mount fits on handlebars and roll bars measuring from 15mm to 50mm in diameter, and are compatible with most straight, drop, trekking, touring, and standard handlebars. This mount can be used on boat helms, golf carts, ATVs, snowmobiles, hang gliders, or other apparatus with cylindrical frames or posts. Garmin GPS devices can also be mounted by simply removing the holder and revealing the 17mm ball mount base.
