Review on Rhinowalk Waterproof Bike Pannier Bag - 27L Capacity for Bicycle Cargo Rack, Laptop, & Cycling Accessories by Colin Arcos

Great pockets! If you fix them correctly, there will be no problems - follow the instructions. I have 2 classic Ortlieb rear wheel scooters in my forest, trail riding, fat tire bike, I have Rinowalks for my city/road touring bike. I don't understand how they can "bounce" off your rack unless installed incorrectly. I see reviews saying they are "noisy" but the person never described what the noise problem was. If your rack is smaller than the clamps, just add some tape. (Duct tape would be my choice). Maybe it was the noise, they knocked. I would buy them instead of orlibs anytime if I could do it again. Not that the Ortlibs are bad, but the price is high. By the way, they are very waterproof and also durable thanks to a back that is integrated into the bag and is held in place by a frame. Maybe that was a problem a few years ago, but not anymore. I have no problem putting them on and taking them off either. But then again, I'm not clumsy.
