Accmor 2 Pack Bike Water Bottle Holder No Screws, Universal Bike Cup Holder, 360 Degree Rotating Bike Water Bottle Cage, Water Bottle Holder for Bike Stroller Walker

This is a perfect upgrade for my old water bottle holder! It actually holds my 32oz water bottle really well. Just got back from mountain biking and no rattling and easy to take out the water bottle and put back. I was hoping this holder would work with the existing mounting screws on the frame since there wasn’t any mention of this on the product description or in the reviews. About the 2 mounting holes the top one is a standard mounting hole but the bottom is about 1/4 inch track which allows for some variance in the distance of the mounting screws. I put the other bracket on my road bike which also works well. Time will tell how long these last but so far they seem pretty sturdy.

the bottle holder is okay, it is soft plastic so holds many sizes of bottles, and they don't fall out. the mechanism to hold it to a bar is a waste of money... it does not hold at all (tried it on my handlebars). and if you do it very tight, it still doesn't hold but the plastic deforms. If it was made of metal it may have worked, but it's made of soft plastic so can not do it tight enough to actually hold. Have not even tried going for a ride with it, because could not hold a 500ml bottle standing still... let alone with bumps from the road. I would have given it 1 star, but I ended up taking the bar clamp off and then using it with a different bar clamp, which I purchased from eBay for $7, that is made out of aluminum.

perfect fit

They are great but I had to take some double sided tape and placed it inside the clamp. It now holds and does not drop down anymore. Great quality just needed a little help with keeping it solid and not slipping down.

Bought this for my 9 y.o. daughter's bike, to mount on the handlebars. There are no installation instructions, but it's pretty simple to figure out and easy to install. Took about 3 minutes. The mount does fit a regular diameter- size cycling water bottle, so that's good. It does rotate up/down a bit. It could be I didn't tighten it up all the way. So far so good, I'd recommend it for kids applications, or where you're not riding centuries, or anything. I do wonder about durability, since most of the holder is plastic, once something breaks - it's probably the end for this thing. If you were a more serious cyclist and needed a handlebar mount, I'd recommend just buying a handlebar water bottle mount bracket - it allows you to mount your own water bottle cage.
