A phone holder or phone case is becoming an increasingly important part of your cycle ride. The smartphone is always there, even when cycling, but holding it in your hands is dangerous. To keep your bike ride safe, it is best to secure the phone to your handlebars. That way, you can easily use it for navigation and you never have to take both hands off the handlebars to look for your phone. Smart phone sleeves are designed to fit your phone and protect it from rain, sweat and damage. So you can safely take your smartphone with you on your bike.
