My kids go to a public school in Brooklyn that is a bit out of our neighborhood. It is roughly a twenty minute walk depending on the focus and energy level of my six year old boys. The other options are the public bus (slow) or driving (parking nightmare). A few years ago my husband bought a bike trailer on Craig’s list which worked great until my kids grew out of it. Our new solution is a Kona bicycle. We bought a Commuter Ute model which is basically a bicycle with an extended back. It is longer than most bikes but it carries my boys easily and has panniers that can carry backpacks etc. The bikes are a bit pricey but we got our used and it’s cheaper and faster than the public bus. We figure we have a good five years before they will be too embarrassed to be biked to school by their mom and dad!
