Anthropometry Question

(Use the tables in Wickens)

You are a designer for a new line of bicycles. Your company has decided it wants to sell an adjustable bicycle, where the bicycle will fit most people - that is, from the 5^th percentile female to the 95^th percentile male consumer. (Assume a North American market base).

1. (8 marks) Assuming that people must be able to sit on the seat of the bike and have both feet flat on the ground (for safety), what should the range of adjustability be for the bicycle seat? (Assume the rider's legs are straight and give the range of seat height from the ground.)

b. (4 marks) Present a brief argument you could make to your boss on how to design a bike that will reach a larger segment of the cycling market. Explain what part of the market you will reach and back up your argument with calculations.
