A cargo bike is a bicycle that has been specifically designed to safely transport heavy loads. Classic cargo bikes have sturdy frames, large cargo areas or boxes and offer space for shopping, luggage or children. Unlike e-cargo bikes, a cargo bike is powered solely by muscle power. Many models have low loading decks or low entryways to make loading and driving easier. Cargo bikes are especially popular in cities because they provide an environmentally friendly alternative to cars for transportation tasks. Overall, the cargo bike shows how heavy loads can be transported efficiently, sustainably, and without motor assistance.
