ROCKBROSBike Rack Pannier Bag Waterproof 9-12L Large Capacity Rear Seat Trunk Panniers Bicycle Bag Multifunction Commuter Shelf Luggage with Rain Cover

I have just been in a 14 mile ride. This bag did not move at all.Fits perfect. Very versatile with the expanding side bags.Loads of room inside for essentials. Inside mine is a first aid kit., spare tubes, a mini pump, cloth, pack of tissues, substantial bike lock and gloves. Heaps of room for more! Love the bottle holder on the bag, this will be very useful when in longer summer rides and you need to carry more water. Yes the underside Velcro straps are a tad too long, but I’d rather that than too short. They are obviously long so they can be adapted. The front Velcro straps are a massive bonus , as you can ride along with confidence knowing the bag won’t slip back. I noticed not many pannier bags have this feature. The rain cover, what a bonus too! Highly recommend this bag. It also feels very robust!Update- one year on, this bag is till going strong! Zips perfect, seams still strong with no sign of getting loose. Been on loads of wet weather / muddy rides too! This bag has been well worth the purchase price.

The bag is well made and comes with a rain cover.It’s a good bag for the price but is a bit small if you want to store your helmet or something in there but it has decent space for smaller items.Stitching is perfect and strong and the zips are decent although I have had issues with one of the zips not moving and don’t want to force it in fear of breaking it.Over all will be a good starter bag and would serve light loads great.

Pleased with the bag so far. Made of good sturdy materials. The zips seem a little flimsy but so far so good. Not used the side panniers as yet. Hold enough for my needs. Recommended.

It's very light weight, not bulky and is very solid and stable (no more saddle bag flapping around and hitting the wheel).It's detachable and easy to take off/put on due to the velcro. It has a strap (it's inside the bag itself when you buy it incase you feel like it's missing)Very customisable storage choices. You put it ontop of the rack like normal, the side pockets open and extend to become side bags for even more storage or keep them rolled up if you don't need it. A huge main storage section with an optional divider and about 20 other pockets.It's quite tall so it will block any rear lights on your seat post, but it has an area at the back of the bag where you can clip lights to.Honestly it's a 9/10. The only improvement I would make is for the velcro to be detachable, so that it can be left attached to the frame and I can take the bag straight off.

I absolutely love this pannier, which sits very securely and happily on my bike. It's exceptionally well made, sturdy and practical, with plenty of space inside. I particularly like the rain protector cover it comes with, just in case the heavens open whilst you're out and about. In fact I loved it so much, that I bought the larger Rockbros pannier for my husbands bike, that too is amazing.

This fits really nicely on my Cube e-bike and I'm able to get a lot of bits & bobs in there. I've got my multi tool, first aid kit, Hiplok DX lock and more.It comes with a little pull-over rain shield but I haven't tested it so can't comment.There are side pockets on the outside and a bit on top to tie down an object, which in my case is a little portable stool. I'm very pleased with it.

bag is nice.. but a bit small compare to the photo. so always measure if is okay with you. if you want large capacity bag. this is not for you.. try another one.

Been using this for a while for shopping trips and carrying gear when I go fishing. The side pockets double in size at least its greatThe only downside is its a little too long for my pannier and I worry it makes my brake light hard to see
