December 14, 2008 Dutch designer Neils Smeltink's clever multifunctional bike design can adapt to the needs of children as they become older by easily transforming from a bicycle to a scooter or a walking bike. Younger children will love to use it as a walking bike or scooter while older children can use it as a real bike.

The "Kid Balance" is great as a walking bike for younger children and will teach important motor skills such as balance, coordination and how to project themselves forward. Once they become confident, you simply add on a crank axle and you have a bicycle with pedals.

The conversion from scooter is just as simple, you pull the handle and the scooter becomes a walking bike.
