My friend built an electric motorcycle years ago (we call it a "mootorcycle" because it has a metal cow skull with glowing red eyes on the front - and a ribcage, and other "bone" work); a couple of months back we upgraded the motor to one of these larger 1 kw beasts. We use 24 volt lead-acid gel cell batteries - the thing easily gets up to some scary speed (well - scary when you're in nothing but a t-shirt, shorts, and no helmet) on the flat. Plus considering the homemade nature of the whole machine... I can't imagine what a motor like that in a kids ride-on would be like, at full-throttle...
