B-Line Sustainable Urban Delivery is a company that was founded in Portland in 2009 to deliver cargo to businesses on electric-powered bikes. The bikes can pull 60 cubic foot cargo boxes with a 600 lb capacity! Not only does this company strive for a lower carbon footprint, but it encourages exercise and healthy living. I think that starting small with electric vehicles like these could really end up making the biggest difference in the end. As much as I want regular consumers to buy EVs, it would be great if more company and school fleets made the switch, along with mail trucks, police cars, taxis, etc.
