I feel a bit thick asking this, but what is the point of two wheeled scooters? We currently have a maxi micro for DS1 aged nearly 8 and a mini micro for DS2 aged 4.5, both three wheelers. I am not sure whether to get DS2 his own maxi micro soon, or whether to get a two wheeled one for DS1 for his upcoming birthday and pass his down to DS2 in due course. Neither has expressed an opinion on two wheels versus three and DS1 is a cautious child who is unlikely to ever want to do stunts on it. I was thinking the kind with two big wheels (like micro cruiser as opposed to micro sprite or similar from another brand) might suit him if it is faster or less effort than his current one. Any advice welcomed!
