"They’re a cheaper and often less stressful way to get around a big city, but compared to a car, bikes kind of suck when it comes to hauling cargo. A trailer certainly helps if you’re willing to put in the extra effort needed to haul it, but there’s now a better solution. Someone’s created a self-propelled bike trailer that makes it feel like your bicycle is pulling nothing at all."
