This weekend, as I continue my process of cleaning out my bins of decade-old papers and such, I came across Strida, which is an amazing little fold-up bike. Reminds me of some other cool bikes that break the usual street/mountain bike mold, such as this lovely recumbent from Bigha, and this electric bike from eGo.
