ECYC Bicycle Seat Post Double Water Bottle Holder

Fantastic idea, but failed in the details. The angle of the mounts is such that my butt constantly rubbed my bottle. Over the course of the first ~15 mile ride this was enough to bend then break my bottle cage. After buying a stronger bottle cage and bending the aluminum bracket as much as I'm comfortable with, it's almost ok. After moving things to a point that my bottle wasn't trying to occupy the same space as my body I thought it would be cool.Wrong. Threw a full 26 oz bottle in for a ~20 mile city race. by the end the steel bracket behind the seat had bent from the weight/road vibration enough that the whole thing bounced a bit when I hit bumps :(Unfortunately, it also doesn't appear to be returnable through the 3rd party seller.

DO NOT BUY! After riding for just a few miles, the bracket had gotten loose. I tried tightening it, but the metal is soft and the screw ruined the threads inside the metal bar that holds the bracket on. I should have read reviews before buying. Now I see that there are several people who had this same issue.

The small plate that the water bottle screws into is not stiff enough to support the weight of full water bottles. It bends after a few bumps in the road and the attachment to the seat rails loosens. This product does not meet design requirements and should not be sold by Amazon.

I bought 4 of these to install on my children's bikes since the frames had no water bottle cage fittings. I have tried many times and ways to secure this to 4 different saddle rails. They seem to be secured until 2 full water bottles are inserted and one starts to bike. This product usually (99% of the time) rotates downward and eventually falls off. This creates an unsafe situation for rider and others near by. I would not recommend this product until the designed is improved to securely fasten to saddle rails.

I’d suggest investing into a better quality bottle holder, perhaps an adjustable one. The angle on this one causes the water bottles to crowd the seat area.

Exactly what I was looking for! This bottle holder frame is strong but lightweight and it has just the right amount of flex to it. I’m very new to cycling and was having trouble keeping my rhythm and reaching the bottle between my legs. This has changed that completely for me, and I now feel much more comfortable reaching back for my bottle while still peddling at a good pace.

With lots of reviews expressing disappointment, I took a gamble. The product works, but could use some design improvements. Depending on the angle of your saddle, the bottom parts of the bottle cages get really close to the tire. I kept seeing people say this fell off with the weight addition of bottles and water. I have kept to 20-24oz bottles, plastic with insulation. I did not go with steel bottles as the weight on those are a lot more. I can only assume the bracket falls off after time is the vibration of the terrain that you are riding on, so could zip ties can give this much more secure attachment to your saddle and reduce the screws from moving with the vibrations. really the only think I would say is the angle of the bracket could be a less angled down and maybe the mount holes for the cages could faced outward to each side to reduce the closeness to the tire.

This is a simple and inexpensive solution to problem of carrying extra water,tools, spare tubes etc. I pack a spare tube, tire changing tools and a mini pump in tool storage bottle behind the seat to replace the bag and have room for an extra water bottle. Only problem I had installing the bracket was the threads for one of the bolts didn't want to cooperate. Finally got it to go in, but it may be cross threaded. Not really high quality product, but it works with minimum expense. Highly recommend using loctite on the threads. After the first ride the bolts had worked loose. Now that I have used the loctite, hopefully that problem has been solved.
