The Swiss Army Bicycle (also known as - militärvelo - militärfahrrad - militaervelo - velo militaire) , officially the M0-5 and later the Mo-93, was utilized by the Swiss Army from 1905 until the mid-1990s.

The classic Swiss Army Bicycle, as used by the Swiss Bicycle Infantry. It was introduced in 1905 and in continuous use until replaced by the MO-93. Swiss bicycle Infantry were phased out in 2001. The most recognisable feature of most Swiss Army Bicycles is the large carry case fitted into the frame. It is accessed from the right-hand side, whilst having a separate document/map compartment on the left-hand side. They were painted all-over basic black, usually semi-matt, although some later models were painted olive drab. Fittings and accessories were variously black, brown or olive drab in colour. The basic model saw many variations as it was adapted for use in many different fields of warfare. Some were stripped down of all non-essential fittings for use as a messenger transport. They were all fitted with 650B (26" x 1-1/2") wheels. They were typically fitted with a 20-tooth rear sprocket, and a 46-tooth chainwheel giving an overall gearing of about 60 gear inches.
They were also fitted with an integrated headlight and bottle dynamo which operated on the front tyre side-wall. Other fittings included mudguards and a rear carry rack. A bag was often fitted on the front was intended for carrying a battle-helmet, but this was often used to carry many other items. Quite often a rolled blanket was strapped to the handle-bars on top of this. A bread-bag for carrying the rider's food rations was usually attached to one side of the rear rack. This bag could be removed and worn as a haversack over one shoulder using a separate shoulder strap. This bag had two straps to hold it to the rear rack and one strap near the bottom to secure it to the bicycle's frame. Anecdotal evidence suggests that soldiers used the bottom attachment to go around their belts to hold the bag on their back. Behind the seat-tube there was a small tool hold-all which carried enough tools to perform basic maintenance and if necessary a "field-strip" of the bicycle. Their heavily-sprung leather saddles help to iron out the roughness of any roads they had to travel. Depending on how the bicycle was set up a large bicycle pump was carried either on top of the carry case or attached in front of the seat-tube. This combination of fittings made the basic MO-05 a versatile piece of military hardware.
The MO-05 was introduced as a single-speed bicycle with a rear coaster brake and a rod-operated front spoon brake. From 1941 they were also fitted with a cable-operated rear drum brake. Some models (believed to be intended for use by medics) had a front drum brake fitted in place of the usual spoon brake. The basic MO-05 weighed a hefty 52lbs (23.6kg) when empty. Post-1946 models were built slightly lighter at 48lbs (21.8kg). Riders had to be quite fit, as some soldiers were expected to carry up to 70lbs (31.8kg) of equipment with only a single gear.
The MO-93 was the first major re-development of the Swiss Army Bicycle. The basic frame layout was retained for compatibility with existing equipment, and outwardly appears similar to the MO-05. It was equipped with a 7-speed derailer gearing system, which is protected by a hefty guard at the rear axle. The MO-93 also differed by having a front carry rack fitted as standard equipment in addition to the rear carry rack. The front rack also served as a mounting for the new headlight assembly which was operated by an axle-mounted dynamo on the front wheel. It was also fitted with modern mountain-bicycle style handle-bars. Many other modern features were incorporated such as rim-brakes. The characteristic frame carry box was retained.
