The City Hub is a customized trailer which can carry up to four containers for the DHL Cubicycle, a customized cargo bicycle which can carry a container with a load of up to 125 kg (one cubic meter in volume). A DHL van delivers the trailer into the city center, where the containers can be quickly loaded on to two Cubicyles for last-mile inner-city delivery. It can then be reloaded for outbound shipments. The solution significantly reduces emissions by minimizing the mileage and time spent on the road by standard delivery vehicles. Each City Hub can replace up to two standard delivery vehicles, with an equivalent CO2 saving of over sixteen tons per year and a significant reduction in other emissions.
