Straps down tight on back rack and has lots of storage ### ⭐⭐⭐⭐⭐ Well made bag *by on Reviewed in the United States March 24, 2022* This bag is well made and sturdy. There is a flap to cover the zipper to help keep contents dry. A rain cover and carry strap are included. It holds a bottle with maximum diameter of 3 inches. I have a 24 ounce Takeya bottle pictured in the holder.I had to scooch the bag forward on my rack, so it hangs over the front about half an inch or so. Otherwise, the bottle holder rested on the raised "tail" and pushed the bottle out. The velcro straps for anchoring are generously sized. My rack is shaped more like a trapezoid than a rectangle, and there was no issue with holding either end securely.I'm underwhelmed with the panniers. They are small, but I was tired of asking Alexa to translate centimeters to inches for me while shopping for bags, so I just hoped for the best. They'll do in a pinch for small extra items, but don't plan on using them to carry anything over 8 inches tall or wide. The zipper opens starting halfway down the pannier. I would have preferred it to zip across the top only, giving the option to carry an item sticking out the top slightly. ### ⭐⭐⭐⭐ Great bag, but straping system needs improvement *by on Reviewed in the United States July 31, 2026* The bag appears to be holding up and is of decent quality. The only complaint I have with it is the straps used to hold the back onto the bike rack - they are using velcro. While traveling to a place to ride I have to remove the bag from the bike because the amount of wind pushing against the bag on the bike carrier is tremendous, so there is a lot of taking the bag on and off the bike rack. Over time the velcro will wear out. Also, the velcro is too long for the bike rack so I have to crisscross the straps under the frame to be secure. I would prefer a buckle system for this instead. Overall I like the bag, just the strapping system could be improved. ## Frequently Bought Together - ROCKBROS Bike Rack Bag Bicycle Bag Trunk Rear Rack Bag Bike Panniers Bike Accessories Basket Storage Luggage Saddle Shoulder Bag 13L for E bike, Bicycle With Rain Cover - ROCKBROS Bike Cargo Rack Rear Bike Rack Quick Release Bike Rack for Back of Bike Bike Luggage Cargo Rack Mountain Bike Rack Most 165lbs Capacity - Lamicall Bike Phone Holder, Motorcycle Phone Mount - Motorcycle Handlebar Cell Phone Clamp, Scooter Phone Clip for iPhone 15 Pro Max/Plus, 14 Pro Max, S9, S10 and More 4.7" to 6.8" Smartphones --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/118320958-rockbros-15l-bike-rear-rack-bag-pannier-trunk-bag-rain](https://www.desertcart.sn/products/118320958-rockbros-15l-bike-rear-rack-bag-pannier-trunk-bag-rain) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-17*
