What could be cooler than carpooling to school every morning on a bicycle? If you’ve got the guts to attempt it, these bikes from Rolling Orange Bikes in Brooklyn have plenty of room for the whole family.

Onderwater Kids Tandem XL
available for $3,900 at rolling orange bikes

The ultimate family bus! By adding a baby seat on the back rack and handlebars, you can comfortably carry up to four kids at a time. The smaller pedals up front allow children to pedal as well–if they get too tired, they can use the footrest and let mom or dad pick up the slack.

De Fietsfabriek PackMax Duo
available for $2,100 at rolling orange bikes

This bike is a bit less extreme, but it can still carry up to three children by adding another seat just behind the handlebars. The handy crate up front can be used for toting school gear (you can add an electric assist battery pack if things get too heavy).

De Fietsfabriek Bakfiets Classic
available for $3,475 at rolling orange bikes

The front-mounted wooden crate on this cargo bike can be used to carry children, pets, groceries, and just about anything else you could imagine. Like the last bike, an electric option is available to offer some relief if the hills get too steep (or you simply get too tired).

Need room for even more? Check out this pedal-powered school bus!
