The Welbike is a folding miniature motorcycle and is one of the World’s smallest military vehicles. It was invented by Special Operations Executive (SOE) at Welwyn (thus the “Wel” in the name) and they used a few but most were used by airborne troops, by Commandos and by beach assault troops.


To properly identify any military vehicle you need to know the make, model, serial number and military number. With Welbikes you need to distinguish between the post-war Corgi and the war-time Welbike. 


An article I wrote many years ago on the Welbike for the MAROON BERET magazine of the Canadian Airborne Regiment which was later disbanded in 1995.

I no longer live in Saskatchewan at that address.

Training with the Welbike before Nov 18 1943. Note the super rare Sten Mk. II bayonet carried by the man on the right in both photos. These photos are proof that they were issued. Circa 1943-44.

Vehicle Serial Number

Engine Serial Number

Welbike Mk. II serial number 3839   Engine XXE 4065 on Welbike Mk. II 3839

Colin Stevens’ first Welbike Mark II – since sold to another collector

Serial Number: 1253

Engine Serial Number: XXE1463

Engine SN: 1463

War Department Census Number: C5152053 (?)

Second Contract, # S.1649 Ordered 19 Nov 1942 Delivery starting in Feb 1943 at 400 machines per month.

This Welbike was acquired in the Summer of 2006 from Brian Marshall of San Leandro, California. A previous owner had painted it blue with white trim and had the number “14” on the rear fender and on the added siren. It appears that it was used by the Shriners in parades. I would love to have photos and more history on the Shriners’ use of these Welbikes – especially No. 14.  Welbike Mk. II SN 1253 as uncrated, August 2006. Note the spare parts that came with it. The seat is not original.

A virtually identical Welbike to 1253 except that this one has no siren fitted. This one was used by the Shriners in California and it is now owned by Brian Asbury in Ontario, Canada. A Mk. II. A third ex-Shriner Welbike is owned by Reg Hodgeson in Edmonton. Partly restored. A late Mk. II

Colin Stevens’ second Welbike Mark II

My Second Welbike – was a very late production Mark II

Serial Number: 3839

Engine SN: XXE 4065

War Department number (original): C5154639


Third Contract, # S.1946 ordered 27 December 1942 and delivered 400 per month starting in May 1943.

Purchased from Mr. Massacci in Warren, Ohio in November 2006. He found it about 30 years ago when he was demolishing a house. He had the salvage rights and found this Welbike which had been sprayed with oil to prevent rust by a previous owner. The tires have split due to sitting on flat tires, the clutch lever is missing and the dome cover for the air filter is missing. Otherwise it is all there and all original – paint, decals and even the War Department number C5154639.

My second Welbike in between Brian Asbury’s two restored Welbikes in Milton, Ontario. – November 2006.  Note the original brown colour on mine.

Colin Stevens’ Third Welbike

A Welbike Mark II, purchased from Mr. Noel Soulsby in Australia, near Melbourne. The seller inherited it from his Uncle who bought it in new condition war surplus after WWII with the intention of his Aunt using it to drive between the house and the shop a few hundred yards away. Apparently it was used very little. The seller repainted it but left the WD number visible.

Frame Serial number 2348

Engine SN XXE 2606

War Department: C5153148

Contract:: It has a contract data plate but I do not yet know what that says.

Reference book “From Welbike to Corgi” by Peter Miller indicates that this Welbike was made on Second Contract # S.1649 dated 19 November 1942 for 1,400 Welbikes. 302 of these were boxed for export – likely this was one of those 302. The cost per Welbike on this contract was GBP 26.18.0 (26 pounds, 18 shilllings and 0 pence). These Welbikes were delivered on 16 March 1943.


(Owner: ? Sold by George Clark to someone in Holland)



WAR DEPARTMENT NUMBER: May never have had one.

For many years it was believed that Bob Coult had the only surviving prototype or pilot model Welbike to survive. Estimates were that 3 or 6 had been made. Evidence now suggests 13 were made before the army contracts.This Welbike was found recently (2005-2006) in Oregon at a collectors show. It was painted red, missing the rear wheel, grips, handlebar locking nut and some other items. George Clark recognized it and bought it. Rebuilt by Pat Papworth of Tsawassen, BC, Canada in 2006. Painted green with incorrect British airborne formation sign on one tank.Evidence indicating its prototype or pilot model status:

  1. Distinctive rounded petroil tanks.
  2. Serial number is simply a large ” 2 ” (painted over by chap who rebuilt it)
  3. Round tubes for foot rests
  4. XXA serial number of engine rather than production XXE number.
  5. Front steering column release catch is fore and aft not angled to side as on later production models.
  6. No doubt other differences will turn up.

Does anyone know the serial number of the prototype which survives in England?

NOTE: If you have original Dunlop Carrier tires with your Welbike, KEEP them even if you put modern tires on your Welbike as the original correctly marked tires are no longer available.
