1902 BSA Spring Frame Roadster
Built by Haviland, Richard & Co, Small Heath, Birmingham
The Spring Frame is the rarest and most sought-after BSA model of the twentieth century. As you can see in the caption under the Spring Frame illustration above (from BSA’s 1903 catalogue), the company did not supply complete machines, but frame builders could buy all the components to build a BSA Fittings Machine.
After four years of negotiation and payment by instalments, I’ve eventually collected this BSA Spring Frame Fittings Machine from my friend Ricky. We have now fitted new tyres and tubes, recommissioned the spring joints, which were very worn, and also installed an earlier BSA Fittings 2nd pattern ‘Y’ chainwheel, as per the catalogue illustrations. A ‘Pattisson Hygienic’ saddle, early BSA inflator pump and Silver King lamp complete its list of accessories. I dare not ride it with this original saddle fitted – I’ve already broken too many delicate, rare, valuable saddles by using them. But I’ll fit a usable saddle to it in due course, add a video to this page, and record my impressions of how it rides.
BSA SPRINGFRAME VIDEO
Though BSA did not manufacture complete machines, the Spring Frame was unique in that they did supply the frame along with all the other components. See below…
So rather than a frame builder manufacturing their own frame and adding BSA fittings, with a Spring Frame they had to assemble the whole kit supplied by BSA. In such circumstances, the bicycle was allowed to bear BSA’s own transfer on its down tube:
‘If it is desired to purchase a machine with our Frame, this must be distinctly specified, and cyclists may identify Frames of our own make by the BSA Trade mark, in gold, on the down tube.’
As you can see, over a century later, the BSA trade mark is still clearly visible on the seat tube of this bicycle.
HAVILAND, RICHARD & CO
Herbert Rd, Small Heath, Birmingham
It is believed that the proprietor of this small business was Mr. Richard Haviland. According to Kelly’s Directory for Birmingham, the company was located in Herbert Road, Small Heath, Birmingham, from 1890-1903. They also made the ‘Haviland’ milk carrier. Being close to BSA’s own factory at Small Heath, I assume that building a bicycle from BSA Fittings was a logical option.
BARTLEETS BICYCLE BOOK
Bartleet’s descriptions were not always correct, but they provide a useful source of reference. Bartleet provides the following description of the BSA Spring Frame that he had in his collection, corresponding to the picture above:
‘No. 45. B.S.A. spring frame. Invented by Dr. Mansell-Jones, “Sunnyside,” Lodge Road, Croydon, Surrey, Patent No. 17987/1900. Weight 10 lbs. Presented by Harry Green.
Two earlier patents by the same inventor, Nos. 28892/1897 and 7141/1899, show a similar result achieved by a system of spring-controlled toggles, which allowed the ends of the seat-stays to rise and fall, and the rear end of the top tube to drop without affecting the position of the saddle. These variations were not marketed.
As shown, the machine was made and sold in large numbers by the Birmingham Small Arms Co. Ltd., Small Heath, Birmingham, by whom it was first exhibited at the Stanley Show in November, 1900. The action of the springing device is self explanatory, and is plainly revealed by the photograph: hinge joints are inserted in the frame tubes at A, B, C, and D. Within the top tube, at E, and inside both seat-stays at F and G., are strong coil springs, so that as the smaller diameter tube slides within the member of larger diameter the springs are compressed and take up the shocks.
A drawback was that the distance between saddle and handlebar was not constant, but varied as the action of the concealed springs allowed the top-tube to change its length. It will be noted that no attempt is made to intercept vibration from the front wheel of the bicycle.
This identical frame was used by Harry Green when he beat the 50 miles road record in 1906, time 2 hrs. 6 mins. 46 secs., and the London to Brighton and back record, the same year, time 5 hrs. 20 mins. 22 secs. This being the only exhibit in the Collection representing the products of the B.S.A. Co., it must be made the excuse for a very brief reference to that extremely important Company. Without such reference not even an epitome of cycling history could pass the censor.’
CLOSE-UP SPRING FRAME DETAILS
On another page (1904 Light Roadster Bicycle built from ‘B’ pattern BSA fittings), I’ve detailed the various components supplied with a BSA Fittings machine, and compared each with the BSA Fittings catalogue.
Here, I’m illustrating the unique fittings for the Spring Frame, to compare with Bartleet’s description.
On all BSA Fittings machines, the BSA logo is to be found at the top of the steering head (below).
Above and below, by the steering head lock, is the hinge joint (‘D’ in Bartleet’s picture).
Below you can see the coil springs in the rear stays (‘F’ and ‘G’). Also, the coil spring on the top tube (‘E’ in Bartleet’s illustration).
Observe the BSA patent stamp and logo below on the top tube coil spring.
And, below, hinge joints (‘A’ and ‘B’) can be seen behind the chainwheel.
Although Bartleet marks a hinge joint at position C, there isn’t one there! I assume it’s a mistake, as I checked it against a picture of another Spring Frame, which also had no hinge joint at this location.
1898 PATTISSON HYGIENIC SADDLE
The BSA spring frame seemed ideal for mounting an engine. The 1904 example pictured below, fitted with a 1903 Minerva engine, is a typical early motorcycle assembled in Australia.
The high quality of BSA fittings and, even more important, their consistent high quality, allowed frame builders to sell BSA Fittings Machines as their own. This was a perfect arrangement for a country such as Australia.
A Fittings Spring Frame Machine would be imported in parts; engines would be imported in the same way. They would then be assembled by a local company and sold under that company’s own name. This arrangement actually started off Australia’s motorcycle industry.
Of course, BSA Spring Frame bicycles were also popular machines without engines fitted. A Spring Frame is offered for sale for £12 in the top advert seen below (from the classifieds of the 7th March 1903 issue of the New Zealand Star newspaper).
After riding this BSA Spring-frame, I do not consider that it was at all suitable for using as a motorised machine. I can see that for the first few years of motorcycle assembly (1902-1904), the advantages of the frame and components being supplied in break-down form made it an ideal candidate. But a motorcycle engine is far better fitted to a rigid frame and, by 1904, builders would have realised this and started making their own frames. It’s interesting that all the sprung parts of this bicycle were not included in motorcycle design; the only sprung part of a motorcycle was the front forks, whose successful development was still a few years away.
It is my opinion that BSA experimented with the spring-frame model while ‘motor bicycles’ were in the developmental stage, and tried them out on the public to fill a gap until improved motorcycle frames could be manufactured. The ‘shock-absorber’ style of suspension on the rear seat stays was already in use by 1900 on some American bicycles; obviously BSA would have seen this. American bikes used one ‘shock-absorber’ while BSA used two. American bicycles using this arrangement were known as ‘cushion frames.’ Colonel Pope gained the cushion-frame patent by combining all the American manufacturers into a conglomerate known as ‘The Trust.’ You can see an example on one of his experimental Columbia bicycles here:
THIS BSA SPRINGFRAME WHEN I FIRST BOUGHT IT
The photo above illustrates the machine before I bought it, with the 1904-1907 3rd pattern ‘X’ chainwheel, which I’ve now replaced with the earlier version.
I also bought a Lady’s BSA Springframe, which is now undergoing restoration.

NATIONAL CYCLISTS UNION ROAD TEST, 1902
New Designs & Devices: The B.S.A. Spring Frame.
The roads, in many parts being in the condition of frozen and muddy ruts, afforded the most favourable opportunity for extreme trial and testing quite thoroughly the new design of spring frame made by the B.S.A.Co.
The springs affecting the rider are actuated by means of a telescoping arrangement, and are contained in the two back seat stays below the seat pillar lug. These springs are made of strengths to correspond with the weight of the actual rider, and no doubt much importance should be attached to this point in order to obtain the very best results. To allow for this telescoping arrangement of the back seat stays, a telescoping immediately in front of the saddle of the horizontal top tube is provided, which latter is hinged at the forward end, and seat pillar lugs are also hinged at the brackets of the front down tube and seat tube, so that vertically the whole frame is flexible, except that part of it to which the driving power is applied. All this is successfully carried out, the object of counteracting vibration being fully attained, and the rider who desires the utmost lightness without the incidental vibration – a concomitant of small, lightweight rims, tyres and saddle – will find, when riding the new B.S.A. Spring Frame, that he is as comfortably, or even luxuriously, seated as if he were on a weightier framed machine with one-and-three-quarter inch tyres, and a coiled saddle.
The ‘raison d’être’ of what, at first glance, appears to be elaborating an expensive design to eliminate vibration as much as possible, will be more readily understood when one realises that to reduce weight, especially at the wheel peripheries, which means vibration is an ever present makers aim at solving, so that the B.S.A. are to be congratulated in at least having made a move in the direction of- without adding to the weight of the frame – Securing less weight at the peripheries and immunity from effects of vibration. To sum up, one has but to be reminded of the sensation felt after a long railway journey to understand what vibration means, and, though lest able to realise it, that it is a well proved fact that for ease of propulsion, one ounce of weight at the periphery is equal to sixteen ounces on any other part of a machine carried on it.
Since my notes on spring frame bicycles, I have had the opportunity of trying the B.S.A. speciality. It is a very comfortable and easy running mount, and by reason of its special construction no power is wasted in the drive. The B.S.A. is the lightest of the spring frames. The makers state the weight to be 28lbs., I found it to be three-quarters of a pound heavier. This weight is for a machine complete with mudguards and two brakes. I may, however, add that 26 inch wheels are fitted, and these help towards the reduced weight. The benefit of the reduced vibration is chiefly experienced from the saddle , comparatively little from the handlebar. The rear portion of the machine is practically isolated from shocks of an uneven road, but the construction does little towards removing the vibrations from the riders hands and arms. The reason for this is that there is no spring in the front fork, it is rigid, as in an ordinary machine. Consequently most of the vibration from the front wheel is transmitted to the riders hands and arms as usual.
I admit that the vibration is lessened somewhat by the telescoping actions of the top tube between head and seat pillar, but the vibration has to pass the handlebar first. If a spring fork was fitted the vibration would be largely absorbed before reaching the handlebar, and in my opinion the machine would thereby be improved for its purpose.
