If this whole two-wheel taxi thing seems a little strange to you and your French literacy is adequate (or you have Google translate) you can check out the company blog and learn everything there is to know about the concept. From what we understand, the prices are decent and you don't have to worry about getting stuck in traffic jams like you might in a four-wheeled taxi. You can order up your ride via the Internet or telephone. If you happen to have an excellent knowledge of Paris and its environs and are a licensed and experienced driver looking for a unique employment opportunity you might want to get in contact with them for that too. Thanks to Mike W. for the tip!
