The phone mount kit for the bike includes a model-specific phone case, a weatherproof case and a universal bike mount. The wheel mount allows both vertical and horizontal phone mounting. It is designed for handlebars with a diameter of 22-32mm. Very easy to handle! The strong silicone phone case gives your phone a little extra protection in case of a fall. The weatherproof case fits over your phone and protects against rain, dirt, sweat and dirt. NB! Does not make the phone 100% waterproof (when submerged in water).
