The Paris city council is launching a free bike scheme to encourage people to give up the motor in favor of pedal power. The BBC reports this morning that the local authority in Paris is depositing 20,000 heavy-duty bicycles, called Velib, in 750 or so special racks around the city and anyone who wants one simply swipes his or her public transport card and pedals off wherever they want to go. The bike can be returned to any Velib stand. Subscriptions range from one day (one euro, $1.38) to a whole year (29 euros, $40). The first half hour of pedalling time is free but if you fail to return the bike after 30 minutes you get charged an extra euro and the penalties go up over time. The scheme has worked well in the French city of Lyon. But out of 2 million Parisians, only 150,000 own bikes. (Other Europeans don’t need encouragement.) Tourists will love them and every city should have them. After all, why not use that fastest-growing and INFINITE fuel source: fat. JULIA WHITTY
