The Brompton A Line Utility folding bike is the least complicated way to start your Brompton journey and get you out the door and riding. From A to B. The essential Brompton. It may look like a standard Brompton, it has a one-size-fits-all frame and parts exchanges have massively reduced its cost to make this a budget-conscious, occasional-use bike perfect for keeping in your camper van or at the cottage. 

It uses the older, flexier stem and handlebar, non-folding pedals, heavier and less adjustable saddle clamp, old-style brake levers and calipers that are not as powerful as Brompton’s current models, no fenders, rack or Front Carrier Block, and is only available with the mid height handlebar, reduced -12% gearing and an extended seatpost. Keeping things simple, it comes with a 3-speed Sturmey Archer internal gear hub which is tuned for the city and zipping around slight hills rather than taking on big climbs. The iconic folding chromoly steel frame is painted Gloss White with Gloss Black front fork and rear triangle.

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 rideability 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.
