Triseven Bottle Holder Bike - Drink Holder Bike - for 2 Water Bottles and 2 CO2 Cartridges - Bike Cup Holder for Drink Bottle - Fit Bicycles - Bicycle Accessories - without Water Bottles

My single speed track bike has no bottle mounts, and I’ve been looking for one of these for a while. Came with all the peices for the mounting bracket and with 1 bottle holder. It was a bit tricky to get the bar clamps in place as you cannot tighten the Allen screw after it is wedged up under the seat. It screwed on tight and seems sturdy enough to take a lifetime of abuse. Came with a little blue dot of Teflon on the screws so they won’t fall out, a nice touch. I swapped out the bottle cage for a white one to match my bike. Will probably add a second for longer rides. There are two mounting positions, I mounted it in the lower angle to keep the bottles from hitting my butt when I ride upright without using the bars. Update: after using this bottle mount for over a year I an still happy with it. I found out that bottles mounted under the saddle are called butt rockets cuz they fly out if you hit too many bumps. I got the Boa FidLock magnetic bottle holder to solve that problem. Now it’s perfect.

My husband love his holder. I was weary about buying this because I thought it was gonna get in the way when he was sitting down, but after some adjustments, it was perfect and he was able to grab it really easily.

Mounts loosen too quickly no matter how tight you make them. Today one of the sides of the mount fell off and now it’s useless. I don’t see any options for mount replacement parts.

This product is what it is and works for its function, however if I knew how difficult it was to install I'd have looked elsewhere. The receiving threads were painted over and I needed my drill just to get the screws to clear out the threads. Had to removed the screws and proceed to installing on my bike to find I needed an L-shaped Allen wrench to screw the top screw in because there wasn't enough clearance for my multipurpose tool. I give it a 4/5 only because it is what I bought and paid for and works, just the install took me about two hours.

Easy to install, seems like good quality material - super simple design. I just put one bottle cage on for now, I like that you have the option for centered single bottle or dual bottle cages. Also happy to see I can mount my tube repair kit underneath without difficulty still. Didn’t have to move the seat to make it fit so that was also a big plus. I’ll update review with how it rides over time.

Held both water cages really sturdy with no issues on smooth roads and never came loose. When it comes to bumpy roads, the screws come loose. Had to stop three times to tighten the screws. Two water bottles were bucked out. I’m going to try longer screws with lock washers and lock nuts. I think it is a great and inexpensive unit, just need to find the right hardware combo to keep it truly secure.

I bought this double bottle holder for my wife, and she likes it very much. It's easy to install, nice color and good quality product. Very stable, it fits perfect and holds bottles very good. Easy to use during ride.

There are two angle options straight and a bit tilted. I choose the straight bottle option and it works wonderfully. Love that it can hold two CO2s. There’s also a nice size gap between the saddle and the bottle cages that you can fit a tube easily if you don’t have other storage options. When I didn’t have a storage option I strapped the tube in that gap with Velcro straps. It held for 100+ miles without falling. Highly recommend this.
