Sandman Bikes out of Belgium clearly think the fat bike platform is worth pursuing, with three different models including the Ti version seen in this video. Fun fact: the Surly Larry 26×3.8″ tires weigh in at 1400 grams and can be run at as little as 6 psi. I don’t think I’d want to be pedaling those up the big mountains! Are you tempted, or even tempted by the fat bike? Or is this a “fun until your friends find out” kind of situation?
