I have been riding a Velotechnik Grasshopper recumbent for the past three years but am seriously thinking of buying a Quest Velomobile. From all accounts this seems to be the most sophisticated (and practical) machine available in Europe.My only dissapointment is that it is not possible to fit a Rohloff gear hub on the Quest as it has a single sided rear wheel mount. (I've got one on my Grasshopper and it has been worth the extra money-- not a problem in almost 10,000 miles!) Any comments?
