3.3.6 Mountain bikes
"When Yvonne Rix visited the USA and the Far East in 1981, she formed the view that mountain bikes would eventually come down from the hills and onto the streets. The reaction from the Raleigh board was, who needs mountain bikes in England where there are few mountains? Yvonne Rix’s response was that neither do you need a 4x4 to drive in London, but you see plenty of Range Rovers in Chelsea. Not a woman to be easily dissuaded, she kept up the pressure for several years. Yet there was still very little interest in mountain biking in the UK: a review of the UK cycling scene in the International Cycling Guide 1983 made no mention of it.
Eventually, Yvonne Rix persuaded the Raleigh board that a move into mountain bike production made sense. In spring 1985, Raleigh launched Maverick, its first range of MTBs. Offered in 5, 15 and 18-speed versions, it was built using traditional Raleigh roadster-style brazing. However, initial sales were disappointing. The MTB market in the UK remained relatively small, with few domestic players and no meaningful presence yet from American or Taiwanese companies".
Spring 1985 was two years after the first US style mountain bikes appeared in UK shops and bike catalogues. By then Saracen were the best selling mountain bikes in Britain, Muddy Fox were established and Raleigh were the about the last UK manufacturer to produce a mountain bike. Initially they imported Japanese made Mavericks, probably re-badged, until UK production could be set up.
