Mount this on my mountain bike. Great cage for my 64oz. hydro flask. Drove through semi-rough terrain and stayed safe the whole time. I don't do crazy bike lanes so I'm not sure it will hold up. I'm pretty sure he'll be fine as he's very secure on the bike. Now I have room for my Hydro Flask when I ride instead of carrying it in my backpack. Definitely a buy recommendation.

As another reviewer noted, the measurements are not correct. I bought a 4.5" separator which is actually only 4" in diameter. This can make a world of difference when trying to match a specific bottle or growler. Luckily I use them for regular plastic bottles when I'm traveling in other countries. In addition, the product is of high quality. For a more secure attachment to the frame/fork, you can attach it with zip ties instead of the included Velcro straps.

5" perfect for attaching my 64 oz growler with hydroflask to my bike trailer. Now my spoiled dog has easy access to a day's supply of cold water on tour. It holds up well when used with velcro or veil strap. I love that I can just detach it and put it on another bike when I'm not using the trailer. I'm not sure how safe it will be over a big pothole or bumpy terrain, but it's great for city riding and bike lanes. Velcro is super strong, seems strong and durable. Made in America. Would buy again
