Mercedes-Benz yesterday announced a new logistics concept: a demonstrator that combines eSprinter vans with e-cargo bikes to sustainably solve the last-mile riddle. 

The Sustaineer (sustainability pioneer) tech demonstrator promises a look at delivery transport of the future. So, what does that look like? 

The electric van is based on the automaker's eSprinter. Mercedes already has fully electric versions of every commercial and private van, and the company expects them to make up more than half of total sales by 2030.
