First on our list of the best bike water bottle holders is this 2-Pack of UShake Water Bottle Cages. These bike bottle holders are crafted from durable and lightweight heat-treated aluminum alloy, which has anodic oxidation to protect the surface and prevent scratches to your bottles. Each one can hold a 26oz bottle of maximum 3” in diameter – although the cage arms can be bent inwards to hold a smaller bottle if necessary.
To affix these water bottle cages to your bike, you will need drilled, threaded holes. The good news is that most mountain bikes come with suitable pre-drilled holes, and if you have an existing water bottle holder, you should be fine. In the pack are 4 x screws, 4 x washers and a 4mm hex key, which is everything you need to easily install both water bottle cages. As there are two, you can choose whether to split them over two bikes or mount both to one, giving you twice the water carrying capabilities.
