Interesting topic as dh loves bikes!!

I don't think I'd be comfortable my kids on road bikes however if it was for a just a little joyride on quiet roads I suppose that would be ok!

With dirtbikes I don't think I'll have a choice - dh wants Louis to have one asap!! I've said he should be able to ride a push bike first! hehe.
Sonya - that sounds like a great idea with the training wheels and adjusting the power...I'll have to talk to dh about that!
Although with Louis only being 16m we've got a while before we have to worry! hehehe.
