About this product
Strap the panniers onto your rear rack and head out with plenty of room for the weekly shop or your commute essentials. The Challenge 21L Capacity Double Pannier Bike Bag helps you carry more without the discomfort of wearing a loaded backpack. Its twin-bag design balances weight evenly across both sides, whilst the snap-shut covers let you grab what you need during stops. Reflective strips add visibility when you're riding after dark.
It's designed to fit most standard bike racks with a mounting system that attaches and removes without tools. Each bag features side pockets with YKK zipper closure for smaller items like keys or a phone. The bags are splashproof to protect contents during light rain. Multiple reflective strips improve visibility to other road users from different angles.

Challenge 21 panniers offer great value with good capacity, sturdy build, and ease of fitting. Some users note waterproofing is adequate but not perfect, and durability varies with heavier use.

Exceptional value
I wasn't sure whether I would get used to Paniers on my bike, (Balance etc) but so these Challenge 21 panniers for just £15 and thought why not? Glad I did, they are great, plenty big enough for what I need, taking packed lunch, camping stove and brewing up stuff on a bike ride. I was really surprised at the quality, particularly for the price. Fitted to the rack in less than a minute. loaded up and set off, Can't even notice they are there when riding. Definitely recommended.

Very pleased with these panniers, great features.
Very pleased with these panniers. They're sturdy and well made, easy to attach and they hold a supermarket shop easily! I like the side zip pockets and the drawstring top, I can fit the shopping in then secure it with the drawstring then pull the cover over. Excellent!

Fantastic value for money
I bought this for a cheap solution to a cycle to Paris and for the price, it was great. It has a large capacity and seems pretty robust, the lining for the inside ripped but this was due to overfilling, and it did not effect it's usability. Luckily I did not test it's waterproofing, but it seems like it could survive some splashing. It was easy to fit to a rack and remove when needed.
