Have a little one with you? Maybe even two or three? Great - let me safely chauffeur them around DC for you. For several years, I've enjoyed pedaling my twins around DC in our customized family “precious cargo bike.” The comfy cushion lined box can carry one or two children (and with the trailercycle attached I can even pedal three kids!). The super low center of gravity makes this bike super safe - like a Pope-Mobile for kids. They also get to enjoy being up front with an unobstructed view. There is no additional charge - I love pedaling this bike and sharing the fun my own family enjoys with this super cool bike.
