All RE signals companies contained despatch riders. Suggest you read the first few chapter of Adventures of a Despatch Rider for background http://www.gutenberg.org/etext/16868

It is quite possible that this fellow was also training in Ireland

The bike is, I think, a Triumph Three and a half Horse Power.

Thanks to all,

Great photos of the bike, yes it is listed on the photo as a BSA or a Triumph, a footnote to the photo said that it had a leather belt which was notorious for sliping in wet weather. Thanks for the link to the book Stephen I did not get a chance to go through it yet but the first letter mentioned Carlow Barracks, looking up the RE site I found that the 33rd company were stationed in Cork 1914.

So once again many thanks,

regards,

Sean.

Those are wonderful pictures. I'm interested in the motorcyles (and biycles) of the era and know next to nothing about them.

Is three-and-a-half a typical horsepower for the period? I imagine more would be needed if there were a sidecar but I don't know if those were common at the time. Does hp = bhp for these purposes or are there several types of horsepower?

Were motorcycles employed in significant numbers for purposes other than despatch at this time? I'm wondering if there were ever motorcyclist scouts, patrols, provost, etc., or if they could even be used as a sort of "staff car" for officers.

bbroadside - I highly recommend the book, "Adventures of a Motorcycle Dispatch Rider During the First World War", by Capt. W. H. L. Watson, R.E., Diggory Press, 2006, ISBN: 978-1-84685-046-2. Very readable and a nice memoir.

All the best,

Dan

It's a 4 hp Model H. Around 50,000 were supplied to British and Allied forces during the war. See my article on the Triumph Company in WW1 here:

Sean, do you know if this man was from Cork, or do you have his name? If so, I may be able to help with some details.

Hi Jean,

Sorry, no information on the man, the photo is from a book that you may be familiar with " Picture That" A Cork Examiner publication and there are some great photos in it.

Regards,

Sean.

Sorry to disappoint, but the Triumph in post #1 is not a Triumph Model H, as this wasn't introduced until 1915. Its a normal 3 speed Sturmey Archer hub geared, probably 4HP (550cc) model of 1914, with direct belt drive to the rear wheel which contains a Sturmey Archer hub gear and clutch. The Model H has a three speed CS (ie countershaft) Sturmey Archer gearbox with chain primary drive and belt final drive, as seen clearly in post #10.

Its also worth noting that most of the early period despatch riders used their own machines, so were a relatively motley crew. Douglas and Triumph DR machines rose to prominence later when machines were supplied by the War Department and the DRs just rode them.

Hey Walrus,

Are they motorcycles restored original bikes ? I just sold an unrestored 1943 WLC, but I would love to find a basket WW1 bike. I'm guessing a better chance of winning the lotto.

Three and a half horsepower was typical at that time for a 500 cc motorcycle however it is not a rating of output.

It is,

This measure was instituted by the Royal Automobile Club in Britain and was used to denote the power of early 20th century British cars. Many cars took their names from this figure (hence the Austin Seven and Riley Nine), while others had names such as "40/50 hp", which indicated the RAC figure followed by the true measured power.Taxable horsepower does not reflect developed horsepower; rather, it is a calculated figure based on the engine's bore size, number of cylinders, and a (now archaic) presumption of engine efficiency. As new engines were designed with ever-increasing efficiency, it was no longer a useful measure, but was kept in use by UK regulations which used the rating for tax purposes.

5b3f100c08953e7d311fb337f33936a2.png

where D is the diameter (or bore) of the cylinder in inches

n is the number of cylinders

This is equal to the displacement in cubic inches divided by 10π then divided again by the stroke in inches.

Since taxable horsepower was computed based on bore and number of cylinders, not based on actual displacement, it gave rise to engines with 'undersquare' dimensions (i.e., relatively small bore), but long stroke; this tended to impose an artificially low limit on rotational speed (rpm), hampering the potential power output and efficiency of the engine.
