Jeff Wills,
The link you posted is broken. I'm disappointed, as I was hoping to learn more about FWD. The Cruzbike Silvio is a good-looking bike, judging from an online video of it I viewed. Haven't seen it up close and personal, I should add.
I'm intrigued as to the "twist-chain style" vs. the "bottom-bracket style" FWD techniques. Which do you think is better for the recreational biker? Or is it more a "six-of-one vs. half dozen of the other" type thing?
