Review on 🚲 Aluminium Alloy Mczxon Bicycle Water Bottle Holder Mount Adapter - Adjustable Road Bikes MTB Water Bottle Cage Mount for Handlebar and Seat Post - Universal Bottle Cage Clamp with Easy Installation by John Murphy

Good product. I've used the bike a few times and the mount worked great on my handlebars. My e-bike has a slanted top tube, so I can't mount a bottle cage on the down or seat tube because of insufficient space. The manufacturer placed the water bottle screws on the slanted top tube. When I jump forward from the seat, my step is right on the bottle cage. What were they thinking? I can get this bracket to rotate if needed without loosening the bolts (I had it too close to the shift drum adjuster and had to adjust) but it didn't move while I was riding. For me it cost $9 when I bought it in June 2021.
