Moulton is an English bicycle manufacturer. The company was founded in 1962 by Dr Alex Moulton, who designed the "Hydrolastic" and rubber cone suspension systems for the BMC Mini motorcar,^[1] and the later "Hydragas" system used by its successor companies.

Moulton bicycles are noted for unconventional frame design, small wheels, and front and rear suspension.

A misconception about Moultons is that they fold in the manner of more recent designs by manufacturers such as Brompton or Dahon. This is not true, though the Moulton design paved the way for such designs and various Moultons over the years have been made in separable versions allowing relatively easy dismantling for transportation or storage. Mass-appeal versions such as the Standard and Deluxe were complemented by Speed versions used in competition.

Thus although Moultons are often included in the folding bicycle category along with small wheel folders, small wheel bicycles would be a more technically correct term covering all such bicycles.

In August, 2008, the company announced it will merge with British bicycle manufacturer Pashley Cycles.^[2]

History

A 1965/66 Moulton 'New Look' Standard M1

In the late 1950s, disillusioned with the design of the classic bicycle, Alex Moulton set about creating a new design. He thought the classic diamond frame was inconvenient to mount, difficult to adjust for size and not suitable for both sexes. He believed that classic bicycles were uncomfortable to ride without the use of wide, low-pressure tyres which increased rolling resistance. He also thought large wheels made a bicycle slow and cumbersome to store, and did not easily fit emerging societal commuting patterns in the developed world, which often combined more than one form of transport.^[3]

Moulton considered that small wheels with high-pressure tyres would result in less rolling resistance, less inertia and hence greater acceleration. He then went on to develop a range of high-pressure tyres in cooperation with Dunlop. Suspension for the front and rear was developed to give a comfortable ride with the smaller wheels.^[4] In this respect, the Moulton bicycle was truly ahead of its time, as bicycle suspension would not become common for another 30 years.

The Moulton bicycle also featured a different frame instead of the traditional diamond design. It is often known as an F-frame or Lazy F due to its unusual structure. The F-frame had no top tube, as such, and could therefore be easily mounted by those with mobility limitations, whether imposed by physical infirmity or by type of clothing.

Impact

When the design was released in 1962, it was one of the first major innovations in bicycle design since the "safety bicycle" in the 1880s and made an immediate impact. The 1962 version (aka "bicycle of the future") was the first production Moulton bicycle with suspension and the racing version was televised the same year in action by road race champion and Moulton employee John Ronald Tovey. Moulton bicycles became an icon of the Swinging Sixties and were sold around the world by the thousand and Moulton was briefly one of the largest bicycle manufacturers in Britain. The architecture and design critic, Peter Reyner Banham, known for often controversial views on technology and industrialisation, was a keen advocate and user of the original Moulton. Eleanor Bron's 1978 book Life and other punctures celebrates travels round France on an original Moulton. In bicycle culture, the rider of a Moulton bicycle is often referred to as being a "Moultoneer" (a play on the word "Mountaineer").

Models produced

The following list of home-market models were produced between 1962 and 1967 in the Moulton factory at Bradford-on-Avon and in the BMC car factory at Kirkby, Liverpool: Continental and Automatic M0, Standard M1, Deluxe M2, Safari M3, Speed M4, Stowaway M5 and the Speedsix M6. A further low volume, high specification 'S' range of Moulton bicycles was produced separately at another small workshop in Bradford-on-Avon and consisted of the Deluxe MS2, Safari MS3, Stowaway MS5 and the top-of-the-range 'S' Speed. After the Raleigh take-over in 1967 (see below), the models changed to just the Major and Major Deluxe only. These in turn were both dropped with the introduction of the Mark III in 1970.

Sellout

The success of the Moulton spurred competitors to introduce similar designs, and competition led to the company being sold to Raleigh in August 1967. In 1974 production of the innovative cycles stopped. Raleigh produced the Major, Major Deluxe and the Mark III (previous Moultons were known as Series 1 and Series 2). The main differences were a re-designed rear suspension using a rubber ball instead of a block and a rear triangle replacing the swingarm of the earlier designs. Some of the early Moulton bicycles are today considered to be collectors' items.

Re-birth

In the early 1980s, Alex Moulton bought back the rights to the Moulton design from Raleigh, and brought out a design along broadly similar lines to the original. Aimed at the high end of the market, this AM series (which remains in production) has a space frame allowing high rigidity and low weight when compared to traditional steel frames. In 1998 the New Series Moulton was introduced. This, similar to the AM, incorporates a Flexitor front suspension, and a rear suspension based on the unified rear triangle principle. The New Series includes the Pylon and Double Pylon high-performance models: in the latter all large diameter tubes have been eliminated, resulting in a pure space frame design and low weight.

Modern Moulton

Pashley-Moulton

To bring the new design to a larger market, a cheaper variant of the AM bicycle design, the APB (All-Purpose Bicycle), was produced under licence by Pashley Cycles from 1992 to 2005. To reduce costs, Pashley use off-the-shelf components as far as possible instead of the custom components of the original Moultons: for example, specially manufactured 17 by 1 1/4 inch (ISO 369)^[5] wheels, tyres, and inner tubes were replaced by the more common 20-inch ETRTO 406 size. In 2005 the Pashley-Moulton design was updated to create the TSR series: high-performance, lighter versions of the Pashley-Moulton replacing the APB.

Bridgestone Moulton

A newer model, stylistically and structurally similar to the original Moulton design, was manufactured by Bridgestone. Known as the Bridgestone Moulton, it was built in Japan and those sold in the UK were assembled in England at the Moulton factory. Like the original Moulton, the AM, and the APB before it, it is available in separable and rigid performance versions. Though similar in appearance to the original design, it is nevertheless a contemporary performance bicycle and features advanced design and components. Links to the Bridgestone Moulton page have not appeared on the company's website since February 2009; the page remains.
