    Back to Pedal Power is a big help to ease the Global Warming problem… In Philippines, BIKERS, FIREFLY BRIGADE and other bicycle commuters are massively promoting the “Back to Pedal Power and STOP Global Warming Advocacy” -Thiking Globally, Acting Locally.

    This Afrigadget helps a lot in bike commuters’ endeavor to STOP GLOBAL WARMING. Good model.
