The Brompton Bicycle company doesn’t bother much with marketing. It doesn’t need to. Its iconic folding bikes spread the word far more effectively than any carefully conceived advertising campaign. And as anyone who travels regularly on the UK’s city streets will testify, the firm’s elegant mode of transport appears to be growing in popularity.

Much of the credit for this goes to the company’s ebullient young managing director (MD) Will Butler-Adams who, since joining in 2002 and taking over from the firm’s founder Andrew Ritchie as MD in 2008, has seen production rocket from 7,000 to 30,000 bikes per year.

It’s a success story that’s been pounced on by a government increasingly keen to talk up the value of the UK’s manufacturing sector. Vince Cable and Nick Clegg kicked off their recent manufacturing summit with a visit to Brompton’s West London factory, and Butler-Adams himself has become a regular fixture on industry panels and think tanks aimed at stimulating interest in engineering. After a few minutes in his company, it’s easy to see why.

Joining the firm as a new products manager in 2002, Butler-Adams was shocked to find an operation that, despite making a profit, was apparently stuck in the 1950s. ’I’d worked for Nissan,’ he said. ’I’d studied engineering and I knew what world-class manufacturing was. I came here and thought “oh my God”. I just couldn’t believe that this kind of thing existed. It looked like a warehouse - there was no sign of any manufacturing going on.’

Transforming the company into a modern business capable of satisfying the growing demand for its products was, said Butler-Adams, a major struggle, and his relationship with Ritchie, who invented the bike in a cramped flat overlooking Kensington’s Brompton Oratory, has not always been easy. ’It was a challenge. Andrew made every decision; you couldn’t buy anything without asking him first. Initially, he didn’t trust me, so I just got on and did things without telling him.’

Through numerous arguments, the two men developed a healthy mutual respect, and Ritchie, described by his young successor as ’something of a legend’, is today focused on technical development, while Butler-Adams, although clearly an energetic presence on the factory floor, also has one eye on the future. ’We’ve probably got to the 1980s now,’ he said. ’We’re still nowhere near 2011.’

The factory, although a hive of activity, is indeed a curious blend of the old and new, with state-of-the-art eddy-current testing and measurement equipment cheek-by-jowl with Heath Robinson-esque testing rigs designed and built by Ritchie several years ago.

What’s more, few of the machines look familiar. The average Brompton consists of 1,200 parts, most of which are unique to the bike, and many of the machines, tools and fixtures used to manufacture it are therefore purpose built. ’There’s more cleverness in the machines than there is in the bike itself,’ said Butler-Adams.

So why does it continue to build its bikes in the UK? It’s a question Butler-Adams has grown used to. ’It’s about protecting our IP [intellectual property]. If we have really clever stuff, we do it here. Anyone can buy our bike, but the knowledge isn’t in the bike; the knowledge is in the 3D models that exist on CAD [computer-aided design], and 3D models are great because they’re bloody difficult to copy.’

An ill-fated licensing deal with Taiwanese firm Euro-Tai in the late 1990s has also left the firm wary of following other UK manufacturers overseas. ’[The Taiwanese-made bikes] were just crap,’ said Butler-Adams. ’They outsourced various frame parts. Then the person they outsourced it to outsourced it to someone else and there was no coherent understanding of what they were trying to achieve. The thing was a disaster area - it didn’t fold properly, it didn’t sit properly, it was just shambolic and it was carrying our brand.’

The patent is a weird concept….in defining in technical detail what your patent is, you’re effectively just giving it away.

Another way the firm protects its IP is - rather counter intuitively - by not patenting anything. ’The patent is a weird concept,’ said Butler-Adams, ’because what you do is define in technical detail what your patent is so people can’t copy it. But in defining in technical detail what your patent is, you’re effectively just giving it away. And then someone in China can say “oh I don’t give a stuff about this patent, I’ll just copy it anyway” and the cost of taking them to court is far more than the 250 grand you spent [patenting it] in the first place.’

In the meantime, Brompton’s engineers are continuing to find ways to improve a design that is, in many ways, mature.

’Materials are changing, FEA [finite element analysis] allows you to take your tolerances to a new level and plastics, rubbers and bearings are improving,’ said Butler-Adams. ’It’s easy to take something very simple and make huge leaps in improvement, but as you get to a certain level, you require far more effort to take far smaller steps in improvement. It’s that attention to detail that takes something from being a product to being a joy.’

In a more radical development, the firm is currently refining the design of an electric bike that’s slated for launch early next year. Equipped with a hub motor in its front wheel and a pannier that carries the battery, the bike will do 15 miles on a full charge and, courtesy of torque sensors, give users an ’invisible hand’ when cycling uphill.

It’s a surprising move from a company so fixated on its core products, and some die-hard enthusiasts might balk at the prospect of an electric bike.

But Butler-Adams remains reassuringly true to the core principles that continue to win over legions of devoted users: ’Get it right and be anal about detail, don’t get involved in fluff and crap and deliver a product that actually works.’

Q&A Re-engineering perceptions

Do you believe this government is any more serious than the last about the manufacturing sector?

It has been easy for large companies to lobby governments to get funding, but this is different - it’s about the sector as a whole, right from the small businesses up to the larger companies; it’s about corporation tax; it’s about trying to change fiscal policy and also the apprenticeship scheme. They’re trying to find ways in which to make doing manufacturing in the UK more attractive. Have they got it right? I don’t know, and I’m not sure they do, but at least they’re trying to listen to industry and are interested in trying to get it right. There is nothing wrong with this sector - it has massive potential. It has been neglected, but fortunately there are still a few embers there and if we give them a good puff we should be able to get it going again.

What are the biggest challenges facing the manufacturing sector?

One area that I particularly worry about is that the perception of engineering and industry as a whole is fundamentally incorrect. We need to change people’s understanding of what our sector is and I think there’s a lot of work to be done with parents. Most parents, like most children today I’m afraid, think an engineer is someone in a boiler suit with a monkey wrench on £14,000 a year. If a child says ’I want to become an engineer’, the parents think ’I don’t want you becoming an engineer - why don’t you become a doctor, or a solicitor, or something respectable?’

How can this perception problem be addressed?

The government has done quite a lot of work with teachers over the last few years, because they recognise they need better people going into teaching. They need to do that sort of thing as well in engineering. You’ve not only got to get parents to understand what engineering is - you’ve got to get the teachers to understand. There is a lot of opportunity for industry to engage with education more and to take a bigger role. The more businesses that get stuck in and the more guidance that government can give to schools, to give them the freedom and the space to engage with businesses, the better.

Is there a case for engineers enjoying a protected status like doctors?

We’ve got far too many institutions. We should consolidate the institutions and we should raise the profile of the qualification that is the chartered engineer. If you look at the medical institution, there is one council that looks after medicine - someone who’s a specialist in the heart knows nothing about the ear, just as a guy who’s a chemical engineer knows nothing about the IC engine, but the medical sector has one council that looks after everything and if you’re a doctor you’re highly respected. It’s not about saying ’oh aren’t I a wonderful engineer, I want everyone to call me engineer Butler-Adams’. I don’t give a stuff about that. But I do care that there’s a misunderstanding - that a bloke who comes and changes a washer can put engineer on his van, it’s simply wrong. Technician, yes fine. But not engineer

  • I had already drank the Brompton Kool-aid, but after visiting the UK last month and touring the Brompton facility, I was in awe. The level of quality and the commitment by the management and staff to their product was inspiring.

    The Brompton is an engineering marvel and will change the life of anyone who owns one.

    Cheers to Brompton.

  • Interesting article & delighted to see they have no intention of moving manufacture abroad.
    Have read about possible Electric version,having seen others that have been modified successfully, & look forward to seeing 'factory version'.

  • Not only is the Brompton a brilliant piece of engineering - perfectly functional and totally ignores fads and fashion (although it is rapidly becoming the must have accessory for the urban commuter, It is also a very refreshing in this throw away age that it is built to last and Brompton's excellent spares policy means that Bromptons of any age can easily be repaired or upgraded.

  • So did you score a new Brompton Jon?

    And congratulations on getting the words "anal", "fluff" and "crap" in the final sentence. Out of context, I'd expect an entirely different kind of article!
