We have lots of options to choose from. The tag-a-long is a great option for children just getting a feel for their biking legs, as it attaches to the back of an adult bike and allows the child to help with pedaling if they want to. Another option is the Kidz Tandem, perfect for the little one who likes to be in charge! The steering, gear changing and braking is controlled from behind by the adult, while the child sits up front and helps out with pedaling.
