Quad Lock Bicycle Handlebar Stem Mount Quad Lock Bicycle Handlebar Stem Mount 23.3mm tall, 35.5mm wide, 50mm long Glass Filled Nylon / Polycarbonate Construction Stainless Steel Fasteners Compatible with all Quad Lock® Cases and Universal Adaptors The Quad Lock® Bike Mount is the lightest, strongest and most secure smartphone bike mount on the market. The patented dual-stage lock is strong enough to lift up to 80 kg (yep, we tested it). So you can ride with confidence over bumps and jumps knowing that your iPhone or Galaxy isn’t going anywhere your bike isn’t. Simply twist and lock to view apps such as Strava®, MapmyRide or Apple® maps as you ride. Detach just as easily so you don’t miss a photo opportunity or important phone call. Remember, it’s all in the technique, not the force. At just 23mm tall and 35mm wide, the Quad Lock® Bike Mount fits seamlessly onto the stem or handlebar of your bike About Quad Lock The unrivalled design of Quad Lock aims to make life easier by effortlessly integrating the power of mobile devices into your everyday life whether you are taking the bike on a ride, in the car or enjoying an active lifestyle. The company was created in Australia by Chris Peters and Rob Ward and introduced to the market through the internet and crowd funding. Their success can be attributed to their point of difference; the Quad Lock cases feature a patented dual-stage lock mechanism that will securely attach your chosen device to the mount. It is also extremely quick to attach/detach the Quad Lock with one hand while giving you peace of mind to know that your device is securely locked. There is a phone case for most phones on the market to give you confidence on your next ride, and if we don’t have a case for your phone we carry a universal adaptor that can be placed on the back of your current phone case.
