Running bikes, long popular in Europe, have become all the rage on this side of the pond with their wooden frames, low seats and ability to instill balance in their users. One of the latest versions to hit the stores is the Wishbone Bike ($250), a three-in-one unit that converts from a scooter, to a first running bike and eventually to a full size running bike for older children. With its three positions, the bikes are designed to take kids from toddlers to kindergarten. Designed by an Australian stay-at-home dad who was taken by the running bikes he saw while visiting Central Park, the bike isn't only pretty to look at, it is Eco-friendly as well. Made from sustainably managed woods, its wheels are manufactured from 60 percent post-consumer recycled plastic.
