The Brompton Borough Waterproof Backpack  is Brompton's newest and best backpack design so far. A backpack that works in dual orientation – landscape mode on the bike, and portrait mode on your back. That turn through 90° is what allows us to make a bag that is spacious enough to hold all your daily gear and comfortable enough to wear on your back. Low profile shoulder straps are comfortable to wear, then are instantly secured by concealed magnets when it’s time to ride. A fully waterproof construction made using a specially developed recycled fabric completes the package, and with a spacious 17L capacity you’ll have plenty of room to take everything you need for your next adventure. Compatible with ALL handlebar types.             

Constructed from 400D TPU-coated polyester and made using Radio Frequency Welding instead of stitching, this bag is 100% waterproofed. Black aluminum buckles are rust-proof and will stand the test of time. A reflective 3M patch on the front provides visibility on dark nights or in stormy commutes

This is an excellent bag for the avid commuter looking for more carrying versatility.

A BIT ABOUT BROMPTON: If you were to walk into the store and look at a Brompton we would say there are three things you should look for in a folding bike. All of them are fairly obvious. One, the bike should ride well - and, on a small wheeled bike that's tricky because there's a fine line between maneuverability (which is a virtue) and twitchiness (which is a vice). Two, the bike should fold well - otherwise you're blood pressure will rise and you'll curse the day you bought it. Third, it should be transportable, or highly storable - because that's the whole point, right?

Brompton is the only company we've seen that answers all three criteria - and believe us, we've tried every brand out there. The reason others can't compete is because Brompton has answered a fundamental engineering problem. If a bike is going to unfold to a large footprint (which takes the twitch out) then it is unfolding to a bigger bike - and by all logic, a bigger bike unfolded would be a bigger bike folded. So, it's pretty much true that for most folding bikes they either have great rideabilty but poor transportability or vice versa. And nearly all of them are a mess to fold.

Not Brompton. Brompton has designed the Platonic form of all folding bikes. The bike folds to the smallest size on the market, unfolds in a highly precise and easy manner, and has the same axle-to-axle footprint as a hybrid bike. How did they do this? By not only designing a clever frame, but also designing some 1200 proprietary parts that make everything fit - and fit perfectly. Oh, and nearly all of this is made in England. No wonder this bike has a cult following.
