I have neglected my 15mm Peter Laing figures this year. I also have to confess – I didn’t paint these 15mm Belgian cyclists, but I did spot them for sale online buried away amongst thousands of 15mm listings.
I took a punt on these being Peter Laing figures as they were not listed by manufacturer. Having collected and painted several hundred Laing figures, I hoped I had correctly recognised these as Peter Laing figures which have quite a overall slender, stylish and distinctive look to them.
F711 Belgian Carabinier Cyclists
These cyclists are attractively based in units on road section bases.
Looking up the website of experienced Peter Laing collector John Patriquin (The Wargame Hermit blog) I saw an unpainted cyclist casting that gave me some hope that these figures for sale online were by Peter Laing. The sales photo left me with a few doubts. http://wargamehermit.blogspot.co.uk/2014/04/peter-laing-machine-gun-cyclsts.html
Nearby were some well painted 15mm Peter Laing WW1 Belgian infantry which I also purchased.
The Belgian infantry Carabiniers wore an interesting black uniform and shako that had yet to be fully modernised by the time WW1 broke out in 1914, so some units went to war in almost Napoleonic uniforms.

Although they are not Peter Laing figures, there are some attractive dog cart machine guns and the odd officer figure by another manufacturer.
Eventually I will split these unit bases up and rebase them as my rules use individual figure bases.
Marvin at Suburban Militarism blog beautifully painted these 1:72 Hat Belgian cyclist versions https://suburbanmilitarism.wordpress.com/2018/08/22/belgiums-carabinier-cyclists-complete/
Another old unposted blog entry on Bicycle Troops
Finding some odd bicycle troops amongst a job lot of Peter Laing WW1 and WW2 15mm figures was interesting – still not sure of maker.

From Victorian era Boer War bicyclists to modern Afgahnistan and the modern Swiss Army, bicycles have played an interesting role in getting infantry and paratroops mobile, from the WW2 Bicycle Blitzkreig through Japanese cyclists on the jungle tracks to the airborne infantry with their parabikes.
Two recent books cover this area: Jim Fitzpatrick, The Bicycle in Wartime: An Illustrated History Paperback 2011 and R.S. Kohn’s book Bicycle Troops (2011) is also available on Amazon.
Both of these I look forward to reading, they are now on this year’s 2019 reading list.
As well as the Belgian cyclists, Hat offer German and other nations bicycle infantry in plastic 1:72 http://www.plasticsoldierreview.com/review.aspx?id=2095Airfix had the odd OO/HO bicyclist in its RAF Crew figures range that could have a rifle added or a well equipped one or two in its WW1 French infantry. Bicycles were also added clutter in some of its OO/HO buildings range (Forward Strongpoint)

Some wargames have simply added Bicycle shaped novelty paper clips.
Lots more information on the interesting Wikipedia entry : https://en.m.wikipedia.org/wiki/Bicycle_infantry

There are plenty of well illustrated museum websites on military bikes:

Bersaglieri WW1 bicycle troops pictured: https://bsamuseum.wordpress.com/1911-bianchi-military-folding-bicycle/
In Mark Thompson’s The White War Life and Death on the Italian Front (p.71) tells the story of a Slovene child seeing Bersaglieri with their plumed hats approaching by bikes into the Caparetto / Isonzo area in 1915 and exclaimed “Daddy, look at all the ladies coming here on bikes!” Hardly the image that these tough mountain troops wished to create.
Many other amazing posts on this BSA Museum website such as AA Cycle scouts in wartime.

Dorset soldiers produce civilian, band and postal bicycle 54mm figures that could be converted to military uses.

Interestingly H.G. Wells, writer of Little Wars , was a keen cyclist with Mrs Wells.
