Man, I like the yuba mundo... Anybody have any real life comparisons between a bike like this and a trailer? So far I've been commuting by car pretty much every day. I've been bringing my bike in or simply leaving it at work and using it to run errands on lunch. In the last 2 years I've advanced at my job from working outside doing physical labor to working at a desk, sending emails, answering phones, helping clients, etc. I've already put on at least 10 lbs. I love biking and love the idea of saving fuel costs while also burning calories!
