WATERFLY Bike Saddle Bag Waterproof Bike Seat Bag Pouch Water Bottle Holder Mountain Road Bike

HEAVILY MODIFIED USAGE NECESSARY AFTER INITIAL USAGE FAILURE......I am a small adult female and I prefer to cruise around on a 20" youth BMX, but sometimes I bike for hours with my kids so it was necessary to still carry water, an inhaler, my wallet and a few other small things with me when I'm gone for that long. I hate wearing a backpack or fanny pack (too sweaty), so bike pack it was. I settled on this water bottle holder/ bike pack and a separate bike phone holder from the same company.Sadly this water bottle holder gave me the same issues as other reviewers stated, when mounted on my seat post. My seat post is EXACTLY the length of this pack, therefore my water bottles hit my thighs with every stride. I couldn't slide it down the post, closer to the tire, to eliminate this problem. And because of the nature of how the velcro is sewn to this pack, I couldn't just strap it to my handlebars either. Alas, time for modifications with various straps I dug out of my junk closet, lol. In the end, I also attached the phone holder (mentioned above) to my handlebars because it kept trying to tip to the side when it was mounted on the frame.Would I buy his again? MOST DEFINITELY! Besides the issues I came across, overall this water bottle holder is very high quality, fits my Nalgene OTF 24 oz water bottles perfectly, is affordable, is water resistant, is reflective, and isn't obnoxiously-colored. I also didn't have to permanently mount anything to my bike. (I was so afraid of screwing anything to my bike because of the possibility of it then rusting the frame.) Even the logo on this pack isn't printed in huge letters like some brands do, THANK GOODNESS!

Bought this product as I have a new Ebike. Given my advanced age (75) I bought a step through model. Putting water bottles in the middle defeats the the step through. This product gives me a saddle large enough to hold a spare, mini pump tools, etc. very pleased with it. 2 caveats. You need about 10” of clearance to clear the rear tire. No problem with my large frame (I’m 6’2”). My wife also has a new step through Ebike but a smaller frame so not enough clearance for this product. We had to find a different solution. 2nd, the product picture shows it holding 2 insulated bike bottles. With all my “stuff” in the bag I can only fit 2 non insulated plastic water bottles. Thus, I’m not going to have ice cold water. Doesn’t bother me as my maximum hot weather ride is 35 miles. I carry 1 plastic bottle with water and the other with crushed ice so I can stay hydrated with cool if not ice cold water. So, very pleased as it solved my step through problem.

I havent' decided 100% if I'll actually keep using the bag, but I'll rate it based on my experience so far.I wanted the bag mainly because I wanted to take two extra water bottles with me on long rides so I didn't have to worry about where I'd be filling up. To that end, it works as expected. I was concerned that it might not hold the 24 oz. Polar Bottles, or that the bottles might hit my butt, but it holds them and neither one hits my butt. The bottles aren't really retrievable while riding, but that is as expected, I mainly use it to swap out bottles when I stop for breaks.The storage itself is also decent. Was able to put a small spray sunscreen, spare tube, tire levers, my wallet, two CO2 cartridges, a few little tools in there and still have some room to spare. It has some inside pouches that could be used for small things, but I didn't find myself using those.One of the only downsides I found about it is that if I clip my safety light to it, because of the angle of the bag the light points down at about a 45 degree angle. I have a backup safety light to attach to the frame, so not a huge deal, but noticeable. Also, the velcro that attaches it to the seat post was rubbing on my shorts and actually damaged them. Don't know that is the flaw of the bag or just the way I ride, but noticeable and required some thinking on my part on how to avoid. When I'm not storing bottles in there (shorter rides), I find the bottle holder pouches look a little awkward, but probably just personal preference.I decided to order a frame pack to hold my stuff and a more triathlon style bottle holder for behind the seat storage, so I don't think I"ll be keeping this one... but still... a pretty decent bag.

I really love this bag, it is almost everything I would hop for in a saddle bag except the side water bottle pockets don't fit my reusable water bottles. I have the same ones shown in the picture but I've never been able to get mine in. I have used disposable 16oz water bottles and those work fine to refill my other water bottle that is within reach while I am riding. I'm shorter so not sure height-wise my reusable bottles would fit. I think they would weigh the bag down just enough to hit my back wheel but I haven't tried. The water bottle pockets also make a great pocket for my over sized cell phone. This bag suits my purpose.

Hi there I don’t do picture reviews a lot but I thought this may deserve one and help someone else make a decision on a purchase I’m buying this for keeping in shape with my little girls and to try to knock off some pounds I put on so this is a pretty low and bike from Walmart however by changing the seat and adding the saddle bag on the back it’s the best bike I’ve ever owned and I definitely have had higher end ones and I definitely am older and more sensitive to .. So you’ve got plenty a room to hold your tools or a wallet and a phone as well as two water bottles which I’ve shown you in there you might be able to get something a little bit larger or wider I suppose but those side pockt aren’t huge. But again five*the other beauty is if you’re one like I’m going to be there ever needs to leave your bike for long the way straps to your seat you just pull your seat out and everything comes right with you if you’re someone who has to go on a bus, Or leave your bike chained up while you’re at work.
