Has Tesla considered applying their car, battery, and solar technology knowledge and expertise to evolve bicycling? Brainstorming, a bit of rambling and mostly science fiction: Super light weight yet strong materials, The frame material is solar sensitive (will charge the battery when exposed to sunlight), Fully magnetic drive-train / gearing system (no chain or physical friction) Pedaling that charges batteries. Regenerative braking The batteries are unobstructive and embedded into the frame (tubes) and/or throughout the bicycle. Chargeable at supercharger stations. Mini charging stations that can also serve as stands to lock the bicycle securely via codes. Highly efficient front and rear electrical motors for hills and distant assist or temporary cruising modes. Operational Modes: If it were efficient enough -- it could be reasoned to have the pedaling charge the battery while the motors drive the bicycle the entire time -- or make it an option where the user can choose modes - cruising (yet still pedaling) for an all electric - battery feeding - slower speed (or a better work-out) vs. kinetic a distance mode for a high acceleration - faster speeds yet lower battery interaction (cannot charge as much or at all while pedaling). On-board computer to provide GPS coordinates of the bicycle's location, optional navigation, and to lock/unlock the bicycle system (electrical) - including remote functions (ex: wireless lock down), diagnostic functions and riding statistics. Would encourage bicycling commuting, exercising, going green, etc.
