500 Waterproof Pannier Rack Bike Bag 20 L

I ordered the bag 2 weeks ago and on tuesday I was doing a shopping trip with them for the first time.
They were super easy to put on, with a screwdriver I was able to adjust it so that it fits my bike perfectly.
Even with maximum speed there is no risk for the bags to fall off the bike.
I wish I could have bought the yellow one but sadly they were sold out.
But as always i'm super Happy with the service and the product.
Well done Decathlon

Would happily recommend these

When it’s strong rain inside it’s wet.
So it’s not waterproof.

I was caught in the rain and not worried about my thing inside this bag but when I unload my clothes it is wet on bottom and the bag has still traces of water inside. The second time I was caught in the rain was worse, a lot of water in the bottom. I suspect it is coming from the backside with screws. You may need to check the design and waterproofing.

Bought these for my friend's touring bike. After installing, we realised the bike bag's backing is too soft. This causes the bike bag to flap & rub against the wheels and disc brakes

I love it but by the time I was trying to fit it in my bike was a nightmare. The introduction is very complicated and not well explained.

Bought one to try and subsequently bought a second. fitted to my bike rack for shopping and other errands. Very useful and so far no problems with them.

This is a good pannier, yes it's not as sturdy as a £70 Ortlien but for the price is excellent. I've been using mince for 6 months on the daily commute and put my work rucksack into the pannier. I don't remove the pannier from the bike nad it lives quite happily there managing shopping trips for groceries or when i pop into town at the weekend.

I bought a bright yellow one, the red is good.

You can improve the bottom attachment by adding a few pop rivets to hold the bag to the plastic backing to make it a bit more secure. Also upgrade teh velcro strap to the hook from the 900 pannier model (see this part https://www.decathlon.co.uk/lower-rail-hook-set-id_8538528.html ) and by drilling two holes you have a much better attachment to your rack. An inexpensive £3.99 upgrade.

Would i buy again, yes i would.

I bought this item as I was sick of carrying a rucksack on short cycle tours.
I have since used it on three trips of between three and five days the longest of which saw three and a half days of torrential Scottish rain and strong winds.
I have always used a dry bag inside the rucksack and continued with it inside the pannier. There was a very small amount of water in the bottom of the pannier on the worst day but far less than I expected.
Frankly no one had dry kit on this trip and my pannier was drier inside than most. I was very impressed at its weather protection.
On the downside, I'm not convinced the soft construction would stand up to heavy use or items with hard corners or sharp edges.
I lined the sides and bottom with a thin sheet of stiff plasric and it's been fine.
The mounting system doesn't inspire confidence, however it's never fallen off either even on some pretty rough sections of trail.
Overall a very good value product for the price.
