Also know this, these scooters now have variable sized wheels. My feeling is that a slightly larger wheel than the wheels that come standard on a scooter are probably a little safer. Most wheels you buy will fit all standard scooters. Check into this. Now here's my two cents.
Scooters are clearly one.
There are just too many injuries that are occurring as a result. I think many parents my age have a romantic view of scooters because they as a child may have ridden one. But the machines that are built today are much faster and more dangerous. In addition, I also will never allow my children to play on trampolines. These two products top my list for dangerous toys.
