Borough Briefcase — the ultimate Boris Bike accessory?

Need to get your laptop and papers from your penthouse on the Isle of Dogs to your office in the City? New brand Borough has just the thing for the Boris Bike ride into town in your pinstripe suit and brogues with their new made-in-England leather briefcase.

Designed to fit into the luggage holder on the handlebar of a London hire bike, the Borough Briefcase is hand-made in East London from Scottish leather.

The Borough Briefcase is the brainchild of designer Graham McLoughlin, who says he got into luggage while working with cycling bag maker Carradice of Nelson.

He told road.cc: "The Borough project itself started out as an experiment into designing and manufacturing quality items in London. Updating the quintessentially British briefcase for 'every-day' travel, the idea came with the introduction of the cycle-hire bicycles along with knowledge of local bicycle culture."

The Briefcase may be the first item we've seen from Borough, but it won't be the last. "We are currently developing a smaller briefcase and range collaboration, in supporting the journey well travelled."

Because Boris Bikes are identical to New York's Citi bikes and San Francisco's Bay Area Bike Share bikes, the briefcase fits those bikes too, and bikes in any other city where the hire bike network is based on the Montreal Bixi system.

The Borough Briefcase comes with a shoulder strap, and a pair of straps to turn it into a rucksack is available as an optional extra. It's available in red, black or brown and each one is individually made to order.

McLoughlin and two friends recently gave the bag a thorough try-out when they used it as their luggage on a Boris bike ride from London to Paris.

You're waiting for the punchline aren't you? Unsurprisingly, it's the price. If English craftsman construction and Scottish leather sounds expensive, the Borough Briefcase's £420 tag is undeniably high for a piece of bike kit.

But posh briefcases are expensive, and the Borough case looks like a positive bargain against, say, a Pickett Traditional Bridlehide Briefcase or a Tusting Grafton.

"We make to order," says McLoughlin. "Selling direct enables Borough to offer a better deal to the people who share and support our values, our passion for crafting timeless items of everyday utility, made in England and designed for London."
