PakRak Commuter Bag(Expandable panniers)

This is a great bag that clips quickly and easily into the Ibera luggage carriers. You MUST have one of these carriers as this will not work with any other (at least not the one I had!) There are 5 main compartments. The largest fits a set of clothes and lunch including a small towel. You can get size 12 shoes into the folding paniers, although this is a tight fit. You then has an extra pocket on the lid of the bag (plus a webbing compartment underneath this that holds the shoulder strap (took me a while to find that). There is also a small pocket on the rear of the carrier that will hold a flexible bike lock or bike tools. Safety is enhanced with reflective strips. After 3 weeks of use I do like this bag. At first I had a bit of trouble mounting the bike as the bag comes quite high and my leg was getting caught when I swung it over the saddle. However my hips have adjusted and now don't have trouble. Added bonus, I am now more flexible than I was ! The downsides, apart from catching your leg, after cycling back from work on a rainy day, mud and watch got into the locking catch on the back and despite running water through it, it is now stiff and hard to use, I do have mudguards but as I have suspension on the front of my bike couldn't use fully stayed mudguards so the rear guard ends at the same point at the rear catch, hence it getting covered in mud. This won't be a problem for more sensible mud guards! The zip for the main compartment sometimes gets snagged on the lining material. They are quality zips so no harm is done, but this is very annoying. There are lots of zips. I very often open the wrong zip. Anyone used to stay dry coats probably won't have this problem! Overall despite the niggles this is a quality piece of kit. I am very glad to be free of my rucksack. Makes peddling to work a lot more comfortable. I'm adding to this review several months later. I am even more impressed with this pack months later. Now done 1000 miles with it. It has not fallen off once and is as good as when I first brought it, except that the material has relaxed inside the bag meaning it no longer gets caught in the zips. I have purchased an Ibera rain cover (9.99!) and cycled in some heavy rain for 45 minutes without anything getting wet!. Changed from 4 to 5 stars.

I have been using this rack pack now for a few weeks fitting on a compatible Ibera rack - I chose this over the other model that comes with a universal rack mount, because people complained in that one's reviews that it fell off. Not this one - the quick-release mechanism holds it securely onto the rack, and it is so convenient to carry the whole bag into the office etc. I have not used it in extensive rain, but seems at least showerproof. It works so well for me that I bought a spare - one of those products that I will regret in years to come if it is not available anymore. I have bike commuted for over 40 years mainly using a backpack, but using this rack pack is so liberating! The main compartment with top pocket is big enough for my daily commute to work, carrying spare clothes, lunch, cable lock, etc. When I go lunchtime shopping, the extending side pockets are really handy. The empty pack with compatible Ibera rack add about 2 kg weight to my bike, but is well made and easy to use!

It looks as though Ibera have withdrawn from the European market as this stuff is now hard (as of Spring 2016) to find anywhere else outside the US and Asia. This is a well made and strong bag. I really like it, and it clips on to both my Ibera racks (IB-RA5 and IB-RA1) in a second. The expandable pannier pockets are a great idea for those trips when you buy too much and need the overflow capacity. The only disadvantage with this over most of the others in the Ibera range is it doesn't come with it's own raincover (though the bottom of the bag is waterproof against splatter from below, the top is not). I bought the IB-BA1-RC raincover at the same time (also available at the time from the same Amazon seller) which fits perfectly. It's also nice looking, strong and a well designed item.

I’ve been pretty pleased with this bag and the rack it connects to. It’s really well made and smartly constructed and has plenty of pockets for stuff. The main bag is very roomy - I carry a jumper, blazer and laptop (Surface Pro 4) in there and it fits fine. The pockets are then fine for phone, wallet, lights, power pack, cables etc. I bought it because I have a bike for cycle commuting that doesn’t have the fit points for a pannier rack. The main downsides of the Ibera system are that it is mounted much higher than a traditional pannier which makes bike handling a bit harder, and with only one mount point it is inevitable that it oscillates more than a pannier. However, those issues are relatively minor and certainly not the fault of the product - just the laws of physics :-) So, I feel these are good, sturdy, well made products and also feel like value for money

I use my pannier for cycling to work and back. It's not overly far but I work 12 hour shifts. There's is enough room in the bag for my dinner and tea. My uniform, phone, chargers, waterproofs, and all my tools for the bicycle. It has a good quality feel to it. The two side pockets open up and clip on to the pannier rack, becoming side bags giving you more space, and the top compartment extends too. Perfect for what I need it for

Great bag with so many handy compartments! So easy to place on and take off the rack. Love the detachable shoulder strap which comes with it. Easily fits in my lunch bag, water bottle, uniform and toiletries.

I didn't think this system would work as well as it does the bag is so secure on the rack and so easy to remove.It's perfect ,fits all my shopping with room to spare.Can't think of a single thing that could improve this bag

I purchased this in July 2016 for commuting purposes, along with the rack. I haven't used it that much as I don't always cycle to work. It seemed ok and safe when clipped into the rack, although the stitching from the shoulder strap pad came off within a few weeks - no big deal I thought. However, I would just warn everyone to be careful with the stitching - particularly on the rear compartment, where you may keep your coins, as I did. I wondered why I never had change when I thought I had, over a period of time, (£1 and £2 coins mainly). Until I picked up my bag from the floor one day and noticed money on the floor. I had a good look around the bag and noticed a hole in the bottom corner of the compartment. This was not obvious to see until I pulled the bottom of the rear compartment away from the bag. I calculated that over the period before I noticed the fault, I probably lost as much change as I paid in buying the Trunk bag!! Very annoying, especially as I was at the time of the purchase, deciding whether to go for this one or the Topeak equivalent. I looked to send feedback to the supplier but there was no option!!
