Knog Frank Dog bag £95

Tested by Ian Sidney, tester for The Bike List

I thought my bag needs were quite demanding until I had the opportunity to test out the awesome Frank Dog bag from Knog. On my daily commute I have to carry my surprisingly heavy laptop on a two mile cycle to the station, to board the train, then the tube, then walk to work. Oh yes and the laptop is accompanied by several files, an umbrella, an assortment of pens and miscellaneous other "manly items" that one can't be without easy access to.

However complicated my journey and whatever essential items I end up carrying, the Frank Dog bag has the answer to everything. Its genius design means it is actually three bags in one - a pannier, handlebar bag and rucksack. The bag IMG_1003attachments are £18 a pop and fantastic for commuters using both two wheels and two legs to get to work. You simply screw the attachments to your bike and leave them there, adjust the Frank Dog's chunky clips and extra-wide shoulder strap, hook the bag on for biking. For walking, simply unhook it from the pannier or handlebar bag attachment, perform another simple strap adjustment and you have your backpack for walking. It's very easy and very simple.

The overall feel of the bag is one of sturdy quality and the styling is good. It doesn't shout, "I'm commuting in day-glow lumo!" from the rooftops and it's available in a good variety of colours. The internal design is amazingly flexible and well thought out. The laptop sleeve is lined with very soft material and keeps the valuable content safe and secure in the heart of the bag. The main compartment has a series of two deep pockets and two mesh pockets - the deep pockets are handy for wallets and USB sticks, while the mesh pockets allow easier access to umbrellas and gum etc.

IMG_1037Need more pockets? Of course you do and the Frank Dog doesn't disappoint. It also has two shallow pockets just inside the rim, absolutely perfect for pens and train tickets when you don't want to be digging around in the depths of the bag.

One initial concern was how well the Velcro would hold under daily use however it is absolutely fine and easily holds the weight of a folded coat threaded through the flap. The final trick comes in the form of a little pocket at the bottom of the bag and it works perfectly. If you find yourself caught in a heavy shower, simply unzip the pocket and cover the bag in the fold out waterproof jacket - it's attached so there is no danger of losing it.

This bag and the attachments you need are expertly designed, crafted and well worth forking out for. The Frank Dog is your faithful old friend and should last you a lifetime of comfortable, stylish commuting.

With the banal thoughts of everyone you know now but a click away, it's refreshing to come across something that cuts though the crap and tells it like it is. Frank only has one friend and it's Frank. And it's only ever had one status update and it's this: Frank is carrying a laptop and a bunch of other goodies in an efficient and handsome manner. What a dreamboat
