If you’re in Geneva, why not pick up a free bike from any of the Geneve Roule offices around the city? Their main office is just behind Gare de Cornavin, but there’s also one on Quai du Mont-Blanc on the lake front and at three other locations around the city. Hire is free for the first four hours, and one euro an hour after that. There are a couple of excellent cycle paths that take you out of the city to the vineyards — which makes for a very pleasant day of wine tasting and cycling. Geneve Roule can provide you with a map. And if you can’t face the ride back, as long as you can make it to the nearest station you can get the train.
