Great product, small and easy to carry around. I bought this product mostly to use on London's Santander "Boris" bikes (city bike sharing). I am able to fit this to the bike's left handle bar, but it has to attach to the actual handle itself, which means it does take up some room where you would normally place your hand on the handle. That said, you can still hold most of the handle and providing your phone isn't too big (I have a regular iPhone 7), then the edge of the phone will sit just on top of your hand. For short journey's this is fine, and given the bike's limitations (i.e. the hugely oversized handle bar mid-section), it's about the best you'll get, and it's far far better than trying to hold the phone in your hand or keep pulling/putting it to/from your pocket.
