This product is as advertised. Fit perfectly on my rear bicycle rack. Holds bike lock, cable, small tool pouch spare tube and more. Easy to remove if you need for safety.

this bag is great for a rear rack...the bag would slide on my set up but is EASY TO SOLVE 100%...but some stick on velcro pads....and mount them to the bag and base rack....problem solved 100%...easy to remove the bag and easy to have the bag EXACTLY where you want it to sit.it wont slide or move or bounce around at all.the straps are fine but the issue is no bike rack is made exactly for a bag strap...JUST GET STICK ON VELCRO PADS that are made for heavy duty.fits rain gear,med kit,and things you need when out on your bike.works ok for gym bag if bike to gym....to hold a micro frabric towel and wipe down towel and so on.

This is great for the price! Enough room and extra pockets for organization!Read some negative remarks about the zipper,,,,, It's a waterproof zipper so naturally it's going to be a little tougher to pull.

I was very impressed with the quality. The attachments to the bike rack were well thought out. Sufficient space and convenient zippered storage spaces also. Worth considering for your bike!

This is a review of the 9.5 liter bike rack bagFit: it velcro'd absolutely perfectly to my bike rack, which is 6" wide. If your own bike rack is much wider, the velcro straps on the sides will definitely come up short and might want reinforcing with additional velcro like one of the other reviewers has mentioned doing.Pockets:For a phone or a slim wallet, the top zipper pocket can't be beat. It's shallow, but long and wide enough, unlike the 2 pockets on the sides. Also, the top pocket's zipper is in the right place, it doesn't sit across your phone (potentially scratching it) like some other top-pocket designs. I'm going to be using this top pocket all the time.Both side pockets are very small, you could theoretically jam a very small phone in there if it had no case, but basically these 2 pockets will be good only for chapstick, bandaids, a folded wad of cash, ID/credit cards, a hanky, your allen wrenches- small things you don't want to rummage for in the main compartment.Main compartment:It's undivided, that's important since this is a small streamlined bag. If you want a large bike-rack bag, you need to keep looking, This one is perfect for me, I wanted a small unobtrusive one, just big enough to stuff a rolled-up jacket into. Note, this would NOT fit a heavy cotton hoodie, or insulated winter jacket. It's just right for a thin wind jacket or a medium weight fleece.If no jacket inside, there's room for one or more water bottles, bike lock, tire pump, sunglasses case, snacks and bike tools. Most of that stuff will have to stay home if you want to pack a puffy fleece or jacket, though. I figure I'll be choosing between water when it's hot, vs jacket when it's coldOther:Bungee cord zig-zagging across top very much appreciated. It can probably hold the aforementioned jacket or fleece, haven't checked yet. It's March right now, so my winter hat and gloves are constantly coming on or off as the temps or wind change, this'll hold them very convenientlyHang loop for your rear light seems well madeA strap is included with the bag for those who'll want to carry it. It's flimsy looking, will never resemble a good looking messenger bag or purse, the upside of that though is, it weighs almost nothing. There's a different model of WOTOW that I returned that has a much nicer looking strap permanently attached at one end (that's their 8-liter model).Digression where I compare this 9.5L model to the 8L one:The 8L item by WOTOW has a narrower 6" footprint, which some of you might prefer, and lacks the bungee-cord web so that it'd look much "cleaner" when you carry it on foot. It has a much nicer strap, but the one I got had nowhere to attach the other end of the strap to (it was an Amazon return, so perhaps happened to be defective or damaged?). The 2 side pockets are the same in both models, but the top pocket in the 9.5 model is MUCH roomier and the ziper's in the right place. 8.0 model has a longitudinal zipper that's awkward to use and could scratch your phone or pull a thread on your gloves.They both look great sitting on a bike, I like the angled streamlined looking shape of both, even though it does "waste" some potential inside cargo space.The one and only possible downside that I see to both of these WOTOW items is their fabric, it kinda startled me right on opening that the fabric seems very VERY thin and very shiny, like the thin shiny material you see in cheesy $5 lunchboxes. It does have that grid-pattern in the weave commonly called "ripstop" which is reassuring. Still, it's so very thin I can't imagine it's very puncture resistant or strong. I was expecting something more like a Cordura knockoff type material. Perhaps that's only available in much pricier bags.Other than that, very happy with this 9.5, I do recommend the styling and all the features

It’s a very nice looking bag with sufficient space for emergency equipment, rain jacket and so on. Mounts easily and securely to my existing rack. I’ve only used it for one season in CO but have not experienced any problems.

Good water resistant material and finish. Easy to strap on or off and carry it with you after parking the bike.

My trike rack is pretty small, but this bag fits securely and holds what I need. We got caught in a rainstorm that was not predicted for another 4-5 hours and the bag did leak. I think it was where the zippers meet. The bag was exposed to rain for at least an hour. Water beaded up and ran off the bag, but some rain made its way in at the rear of the bag. I suggest putting a couple of zip top bags in to use if caught out in a storm.It’s not a heavy duty zipper, but works just fine. Good looking bag.

Just the size I needed, easy to fit/release and secure.

Its an attractive bag that can hold the things that may not fit in pockets or elsewhere on the bike. When the internal area is full, elastics enables additional items to be attached. ie. Drink bottle. We find it very easy to take on and off. Velcro holds the bag firmly in place.

Just arrived and haven’t used it on a trip yet but it seems well made. Good design with straps that secure to the rack tightly. Not so big ideal for a long day’s touring trip to carry rain jacket, leg warmers, arm warmers, sunscreen, snacks, a spare folding tyre and a couple of tubes etc. Recommended.

Quality seems strong — it may be a little bit more narrow than some but it is still a decent size. The one plus that I really like is that underneath there is a zipper so if you take this unit off of your bike (very easy on/off - 4 Velcro’s) you have a single strap that can be pulled out and hooked to the opposite end of the seat bag. The only negative is that the strap is not super long. If your upper body is skinny it might be perfect but if you’re a little more husky it might not be the best to wear like a single strap back pack. Still I nice bag. Zipper is ok - middle of the road. Definitely not the highest end but not the lowest end either (somewhere in the middle - probably could have done better with the zipper but it seems ok to me - not a deal breaker).Pluses: nice design (looks good), decent storage and can wear like a single strap backpack.Negatives: zipper just ok maybe a little short/narrow not expandable like some and backpack strap is a little short.

Perfect size and has a lot of storage capacity, good quality and price
