Cargo trikes have also given Danish parents with small children the option to ride instead of drive. Nihola's trikes, made by hand in Denmark, are slightly lower to the ground in addition to having three wheels--so they're easier to balance on than on a typical bicycle. Nihola offers everything from padded bench seats (shown) to cargo boxes with baby car seats, to box hoods for rain and snow protection.
Pedicab bikes are also common in Copenhagen, especially in tourist areas like the Nyhavn Docks. Once frequented mostly by sailors and prostitutes, the Nyhavn Docks are now a city centerpiece with cafes and restaurants located both canal-side and on the docked boats themselves.
I'm told Copenhageners even take to the streets on their bikes and trikes in winter. In this photo from the Cycling Embassy of Copenhagen, two women, one on a Christiania and one on a Nihola, brave the snow.
