In Boston there's no place to ride a "real" motorcycle for a kid, since basically if they are gas powered the rider needs a license. But there is a giant park just down the street - 1.5 miles around and an electric scooter or "dirt bike" is allowed. Razor lists two models, the MX650 and MX500. They both have 36V SLA batteries, which could probably be upgraded. Customer reviews on Amazon are all over the map from no-way to awesome. Anyone use one? Know any forums? Any alternatives?
