ROCKBROS Bike Trunk Bag 17L-45L Rear Rack Bags for Bicycles Waterproof

Great bag, solid constructions, saddle bags pop out and are protected. Fit 3 bags of groceries into this thing.

I wish it was made out of leather but I've got really nothing to complain about. it's well made. the panniers are easy to get open and it stays in place so no worrying about an odd strap etc. ending up in the spokes. The only thing wrong with it is that it encourages you to carry around a lot of junk. The storage capacity is great. the zipper quality is okay. not the best but certainly not the worst.

i commute on bike. this bag strikes a good balance between having a main pocket big enough to hold my usual gear, and being small enough to throw over my shoulder and bring inside with me. the saddlebags are perfectly good for bringing home takeout or whatever i forgot to get during my last big grocery run. i like how the rain cover is high-visibility yellow, great safety detail and i throw it on for nighttime visibility too. bag feels like its solid enough to take a fall (although ideally i won't find out!). overall pleased. EDIT: its 2025 now. i bought this and wrote the above in 2023. its still holding up just fine. no issues with stitching or zippers, and it stays on securely. the yellow rain cover is a little faded from sun, because i use it for visibility no matter the weather, but its still pretty bright and the reflective strips still work. id still recommend this bag! (and yes, it can take a little fall and be ok.)

I wanted to love this bag. But returned it. The size is perfect. The construction is sturdy. The expandability is awesome. The top of the trunk expands up in the back and holds all my tools and biking gear with room to spare. The fold out panniers are big -- I can fit a 15" laptop in a sleeve as well as pants, shirt, a sweatshirt, and more. The water bottle cage is useful and secure. The webbing on top is useful for stashing my jacket mid-ride. The reflective trim is powerful. The price is perfect. However, I returned the bag because of the velcro attachments. The velcro works fine, but I have a wide rack and fenders with little room to maneuver under the rack. It would take me 20 minutes before and after each ride to attach and remove the velcro under the bag. Super frustrating. My bike rack has the Dutch-designed MIK clip-in system built-in. I replaced this bag with a MIK bag that I don't like nearly as much so that I could avoid wrestling with the Rockbros velcro bottom straps. Rockros: PLEASE COME OUT WITH A MIK ATTACHMENT VERSION OF THIS BAG. PLEASE !!! I would buy it today and pay an extra $ 100 for the convenience. Seriously.

I love it. Fits perfect with no heel strike as a 6ft guy on my Rad Power Expand 5plus. It’s good quality and offers so much extra space with the paneers. Fits very stable on my bike too.

After owning this and using it for three years now, I can finally say it is a great bag, nothing is coming apart, and it hasn’t faded. It is perfect for what I’m using it for and it also has the pannier bags which come in very handy.I would highly recommend this bag for bikers.

Working good my bike

I love this bag. I put a MIK adapter on it and it fits great on my MIK carrier. I love that it has built in panniers so I can carry more stuff if needed. The center part itself carries a lot of stuff and that's what I use most of the time but I have used the panniers a couple of times for longer rides. The panniers are fairly small so if you're going on a really long trip I'd recommend getting dedicated pannier bags instead but if you just want the versatility this bag offers I say don't hesitate. It's very well built and sturdy and also attractive. I also like having the extra water bottle holder on the back of it.

Great quality. Hard side keep loads where it should stay. Zippers are good quality. Like size of compartments and how they pack away. Nice rain cover. Only thing missing is some small pockets for keeping items sorted. Nice rain covers.

Very nice bag. Using on an e-bike. Lots of storage. Best price I could find for Rockbros bag.

Bonne qualité et polyvalent. Un peu lourd mais parfait pour un vélo électrique.

Awesome bag for the price seems well made

Excellent produit. c'est mon deuxieme que j'achete, le premier c'était pour le vélo de ma conjointe.
