I was reading this EcoVelo post on multi-modal bicycling and there were a shower of comments about this recumbent called Cruzbike. Not only are there stock models, but there is also a build kit that you can take a y-frame full suspension mountain bike and turn it into a ‘bent. Some Cruzbike discussion on bikeforums. Why would you want a ‘bent MTB conversion? For starters, you can place it on a bus bike rack, (can’t do that with any long frame bikes). Also, an average recumbent listed on craigger’s is often hundreds of dollars. This is relatively quick and much more affordable way to put a used MTB into service as a commuter.
