"Captivating" is probably the best word to describe the RetroVelo bicycles from Germany.
RetroVelo has launched an entire lifestyle for bicyclists. One club motto is, "We promise nothing and deliver." One fan said he had never had an urge to party with the makers of any product until he met the RetroVelo folks.
There is a whole "joie de vivre" which can be felt at their website. The variety of models and colors are all balloon tire bikes just wreaking of fun.
