Firms urged to act over growth in mountain biking
"Scottish companies are being urged to take advantage of a predicted 30% growth in mountain biking in Scotland over the next five years.

TIS said the activity already generated £119m a year for the Scottish economy.
Market share is predicted to increase to £155m in the next five years..."
