Im having my 1st baby this coming July, im already thinking this question. My wife also rides MX so the poor child will have no hope :lol: Im thinking starting round 2 - 2 1/2. Cut down seat on a pee wee and restricted.
personal preference as said above but remember you then have to cart clean and maintain 2 sets of bikes and gear... it's a pain sometimes
If shes too small for a 70 etc, get a jr50 there slow low and perfect for beginners (probably cost around 800 - 1000) great confidence builderNot keen on one of those quads lol. I want her on 2 wheels!! But I am seriously considering that atomik tuffmoto, have to see it in real life first - anyone got one? If it's too big she'll just have to wait till she is 3 and I'll get her a pw50 it seems. 21 months at the moment and getting around well on an electric trike.
