We've seen a multitude of bicycle concepts here on Core77, but perhaps none as fully worked out for manufacturing as designer Evan Solida's "Rael." The amount of thoughtfulness put into this bike is unparalleled, as can only be done by someone with as much riding experience and design experience as Evan.
Rael is Evan's second startup rooted in cycling. We reported in 2009 that he founded Cerevellum to produce cycling accessories like the HindSight 35, a cyclometer with an integrated blindspot camera. Check out the full details on the Rael bike over at RaelBicycles.com
Evan has been developing the concept publicly over on the core77 discussion forums under the avatar of 6ix, check out his full process HERE. It is always exciting to see our 14,000+ member community engaged in giving feedback and input into projects!
