Middle aged men in Lycra a term coined by leading market research firm Mintel.

Michael Oliver, who wrote the report, said: "Thirty or 40 years ago, people would ride a bike for economic reasons, but our research suggests that nowadays a bicycle is more a lifestyle addition, a way of demonstrating how affluent you are."

The research shows that growth in bike sales is being propelled by 35- to 45-year-old men with families, who instead of going off and buying a sports car as they approach middle age now go for high-end bike instead.
Spring will usually bring Mamils out of hibernation in search of fresh Lycra and carbon fiber - their staple diet.
