It all depends on how comfortable you and your child feel. 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, or free-wheel if they’re not quite at that stage. 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. The Kidz Tandem also comes with an optional seat attachment if the child is not quite up to pedaling just yet.
