Perfect size
Color: Black
Excellent rear bike bag. Fit perfectly on my wifes Cannondale

Very good bag
Color: Black
The price is very fair; very good construction. Many have said that the zippers are finicky but I haven't had much issue with them. The bag is meant to be waterproof so the teeth have a hidden design, and you have to make sure the zipper closes over the fabric, otherwise it'll snag. Have already taken it out in wet conditions and can attest, at least in part, to its waterproof-ness. I'm sure if you dunk it in water it'll leak, but your stuff will be safe if you get caught out in the rain. The reflective portion of the bag is ACTUALLY reflective (which I didn't get to snap a picture of, I'm sorry). Some have complained about the bag's shoulder strap not disconnecting from both sides, but I disagree that this is a problem. It's actually designed so that when you unhook it, you can tuck the strap into a pouch on the underside of the bag. Very clever design! The velcro straps that secure it to the rack are very strong and give plenty of room for over-packing (you'll never be short of length). Super easy to rig up to your rack. The only thing that would bring my 5 star rating to a 4 is that the ends of the straps are a little too pointy for me, but that's such a non-issue that it's not worth losing a star over. Fits a pair of gloves, a safety vest, a 32oz cirkul bottle, my phone, and some various bike tools. Lots of space! Bag works great and can't recommend it enough for someone looking. A side note for cricut users: this bag takes heat transfer vinyl AMAZINGLY well. I was almost certain the fabric would melt, but it easily withstood up to 305°F for 30 seconds. You just have to make sure the bag is stuffed with something to give it body while you're applying the vinyl. ... show more

Great find!
Color: Black
Exactly as pictured. Fits my ebike great! Now i don't have to worry about my stuff getting wet or falling out of the basket. Wish I'd have purchased something like this along time ago. Appears to be of great quality. Love it!

Worried about the zippers but otherwise a pretty good bag
Color: Black
Have only had this bag a couple weeks (replaced an older bag that's wearing out), but so far I like it quite a bit, style, size, and function wise. The zippers seem to catch around the corners, so I'm being careful with them, but that's probably my point of greatest concern. My favorite thing about this bag is the way it attaches to the rack. My previous bag's straps were designed to go all the way under the rack and to the other side of the bag, which was fine if I only had the trunk bag on the big. But when I also had panniers, it was hard to get just right (I don't like trunk bag/pannier combos). The fact that this bag's straps just loop onto the rack on the same side they're on has so far been much easier to manage. Capacity is good. Lots of extra pockets is good (helps to stop having so many small loose things floating around getting lost in the bag). Has been through some rainy rides (no downpours) and seems to be working as designed. I've since gotten two other wotow bags and am liking how they do things thus far. Update: After a downpour, stuff inside the bag DID get wet. So... unfortunately, still need that rain cover. ... show more

You won't be disappointed with this bike bag
Color: Black
Very nice bike bag with zip pockets on both exterior sides, invisible zippers all around and large top opening. The quality of this bag is very good, and it sits upright and is solid. This one doesn't collapse of fall flat when empty, looks great on the bike. There's a shoulder strap that disappears into it's own pocket on the bottom of the bag until ready to use. There's an additional shallow zip pocket on top of the bag. Well worth the price, this is a nice bike bag. ... show more

Nice on my fitness bike!
Color: Black
Bag sites well on my Trek rear bike rack. Has enough room for a large book, a bike tool kit and a heavy 5ft security cable. Maybe could fit one or two more small items in. Looks good imo, zippers on pouches seem durable and reasonably waterproof based on design. I've not had it in a rain storm so can only comment on my view of the design. ... show more

Great bag!
Color: Black
Great bag. I’ve got it attached to my Tamobyke to replace the bag it came with. It’s secure, doesn’t slide around on the frame, fits the wider bike frame of my e-bike, has done a great job of keeping my bike tools dry. Looks great, works wonders, easy to install. Do recommend.

Nice bag, but bad straps
Color: Black
Lots of good things about this bag - it’s spacious, has several different pockets, water-resistant. But the straps do not hold the bag securely to my bike rack - they are far too loose, with no adjustability. I had to buy additional Velcro straps and jerry-rig it so it wouldn’t slide around so much.
