Meet the Vagabond: a bicycle that you can turn into a stroller under a minute. It is useful for parents with small babies. In bike mode, Vagabond has two wheels front and one wheel in the back. As you can see in the below video, the bicycle turns into a stroller in a few simple steps.
The Vagabond was developed by Antonio Garcia Lopez. It sets you back $1330 plus shipping. Nice idea though.
