90% Gear Review: Lifedge iPhone Bike Mount, Waterproof Case, & Float Accessory Sara Kay Mooney August 13, 2020 Discover, For Outside, Gear 1 Comment Specifically, I tested the iPhone bike mount, the Waterproof Case for iPhone5, and the float accessory. The mount arrived in sleek packaging, complete with easy-to-comprehend directions. Attaching it was quick and simple. Once I fastened it to my handlebar, I simply popped my phone into the Lifedge waterproof case, which then attached directly to the mount. Snapping the case into the mount on either side, I had no doubts that my phone was secure.
