During the merger of Locomotief and Simplex (between 19), these brands sold 40% gents models and 60% ladies models. While L & S produced 25% roadsters (rim size 28 x 1 1/2 inch), with Gazelle this type of bicycles covered almost 40%.
Moreover, L & S sold strikingly many budget-bikes equipped with freewheel and caliper brakes.
Of course, these figures assume that the bicycles still 'on the road' today give a correct image of what was sold then.
But there is more general information to be derived from this database: aluminium rims for sports and roadster bicycles were introduced in 1948.
By collecting as much frame numbers of these brands as possible and comparing the bicycles' characteristics, even that could be deciphered.
However, the cream Delta Cruiser tires look brand new, and the "O-Lock" on the back wheel looks like a recent addition.
The resulting year is usually correct within a margin of one year. If a headset label is missing and no brand name can be found, specific characteristics may be the way out.
The values shown in the chart represent the year of construction of the hub. What kind of frame number, where is it stamped-in, type of bottom bracket, type of headset-lugs etc.
The Raleigh Bicycle Company is a bicycle manufacturer based in Nottingham, England.
Founded by Woodhead and Angois in 1885, who used Raleigh as their brand name, it is one of the oldest bicycle companies in the world.
However, for the purpose of brand identification data of these bicycles can be very useful.
But even the well-known brands can be problematic, especially when the system of frame numbering is complicated.
By October 1999, the resulting database contained data of more than 3,000 bicycles.
