2-Strap Style Portable Boat Speaker Mount,Portable Speaker Holder for Boat Railing Frame,Waterproof Outdoor Adjustable Strap Fits Most Bluetooth Wireless Speakers Stabilizer Straps,Black

Works as advertised, but will not work on a jeep roll bar. It fits speaker easily.

I use this to attach the speaking to the roll cage on my off-roader. Snug fit and keeps me in tunes all day.

Its a great product best sound for money hands down

This adjusts easily and holds on strong. The strap side that does against whatever you're mounting to has a bunch of rubber grips that provide fantastic traction. I installed this on the fork of my mountain bike for bike packing trips. I love it it works so well for that purpose. It easily holds a nalgene bottle.

But got it positioned on my upright

Minimalist, ultra effective, lightweight, easy to use, no nonsense, doesn’t cover up any part of my speaker and allows me to bump while I ride. I’m very pleased and I highly recommend this style of speaker holder for your bicycle. It is all you need.

Fits for JBL Charge 5. Doesn’t fit 2”roll cage

So, I've got a cylindrical BT speaker that is just a bit too large to fit into a bike bottle cage, but there are times I like to bring it along. I've found various ways to jerry-rig it to attach to the bike, but never in a way that made me feel it was particularly secure, and also not in a way that kept it from shifting and getting in my way. This takes care of all of that. It is big enough to handle my speaker without issue, it goes together super quick and simple, and it holds the speaker right where I want it without any concern for it falling off/out or shifting and getting in the way. Overall, VERY happy I picked this up, and I'm sure I'll be making use of it for a long time to come.
