The engined Bicycle.
With the advent of the petrol engine, some bright spark was able to combine the two. It is kind of ironic when you think it was two bicycle makers, the Wright brothers who flew the first aeroplane in 1908.
Gottlieb Daimler was the first to try in 1880 and by 1895 he was in production with the Einspur 265cc. Prior to the petrol engine were steam powered bikes by a Frenchman Michaux-Perreaux Velocipede from 1869, but by now this concept was abandoned.
The powered cycle format that we toady know for both the bicycle and motorbike was adopted in 1869, but the bicycle funny enough continues to change shapes, until the 20th century.

Design that changed Aviation. Part-One.
The forerunner to the De'Havilland Comet.
The design of anything is very important, that is how a classic is created. Aviation has made bounds and leaps in the last one-hundred and six years, from a bicycle powered glider to the Space Shuttle, from the World War-one bi- and tri-planes to the Lockheed SR-71 and the MIG-25.
Most early aircraft relied on two wings, one located above the other and they all nearly appeared box or cylinder shaped. But in 1934-36 big changes were to occur in the design of civil aviation with the MacRobertson trophy. it asked for a compatible aircraft to the DC-2, which could carry 1000ib of mail, 2500 miles at high speed. A.E Hagg and Major Frank Halford rose to the occasion and developed the De'Havilland DH 91 Albatross.
This designed body was a pre-World War-II body shell that would be used on the first commercial jet liner some eighteen years later.

Tractors. Part-One.
From farm work to mowing the grass.
The Tractor has made great strides and progress over the lat 120 years, from a farming machine to replace the horse to moving your garden lawn. The first machines were heavy and clumsy, but they were able to draw ploughs and were easier to be put to work than animals.
The tractor came into its fore in the great plains of North-America and the Soviet Russia in the production of cereal crops such as wheat, barley and maize. Later around the 1920's they were reduced in size for general farming duties and as engine technology improved became more versatile and easier to drive.
We associate Massey-Ferguson and Henry Ford with machines in the British isles, while Case, Caterpillar and John Deere with Europe and North-America.
