They can pedal faster or they can have a bigger wheel. If somebody wants to travel faster there are two key variables. If somebody can turn the pedals 100 times in a minute they will travel about 220 metres (about 240 yards), which is just over 13 kph (kilometres per hour), which is about 8.2 mph (miles per hour) The circumference of the wheel is also the distance it will travel along the road if it makes one full rotation. If the diameter of a wheel is 0.7 metres, then the circumference is 3.142 x 0.7 = 2.2 metres. The circumference of a circle is given by π x diameter. If the circumference of the wheel is 2.2 metres (just over 7 feet), then if the rider turns the pedals 10 times, the bike will move forward 22 metres (about 24 yards).įor most people, the fastest they can turn the pedals for any reasonable amount of time is 100 times per minute, for many people the limit is much lower.Ī typical size for a bicycle wheel is 0.7 metres (0.8 yards) from one side to the other, i.e. The link, of one turn of the pedals to one turn of the wheel, means that the distance a bike moves forward is determined by the circumference of the wheel. If the pedals are on the front wheel, then each time you turn the pedals once the front wheel turns once. When the pedals went round once, the drive wheel went round once. In most cases insight is based on data, but once the insight has been found, not everybody needs or wants the data.īicycles in the 1870s had a simple relationship between the pedals and the wheels. This post is set out to follow, and thereby illustrate, the flow from data to insight. With all of these limitations, why did this this type of bicycle become so popular, why did it disappear so quickly, and what can this teach us today?ĭisclaimer: you can jump to the insight, i.e. These bicycles were hard to mount, tricky to ride, and resulted in many injuries (the term ‘header’ was used for people who fell forward off the bike). Penny-farthing bicycles (or high wheelers), like the one in the image, were very fashionable in countries such as UK and USA from the mid-1870s, for just under 20 years. Why did a penny-farthing bicycle have such a big wheel? However, it may make it clearer if I share an example of something I think is an insight, all about Victorian bicycles. Generalisable is it specific to the case under investigation, or can it be applied elsewhere?.Capable of being actioned, in particular in ways that create impact. Why/how, does it provide an explanation of how something works, not just a description of what it does?.Novel, does it tell you something you did not see before?.Typical definitions of insight in the context of marketing and market research tend to include concepts like: ‘ What is an insight?’ and ‘ What’s the difference between a finding and an insight?’ are two questions I am often asked.
