Paris Bike Tour

I found something that will prove useful if you come to Paris and want to discover the city "differently": English speaking organized bike tours. The Fat Tire Bike Tours (that is what they are called) have apparently been going on for 9 years but it's the first time I noticed one of their bikes in the street. I never tried them either, so if anyone had, please give us some feedback. I love the Paris Tips section of their website, it's always fun to see what foreigners are interested in ;)
