ok. have to share this...
ds (3 years 5 months) can officially ride his bike from today.
we bought it from islabikes.co.uk and it should last him til he is 7 or so. they do all sizes, really good well made bikes.
it is heavy but he has gotten used to that very quickly and wheels it around when not riding it no problem.
we started him without pedals, he was just touching the ground, and then he started putting his feet up where the little brackets for the pedals go, whilst we held onto him by his coat.
then pedals, withus holding on to his coat. he needed less and less re-balancing and now is doing it himself.
we found the most amazing place for him to practise today: an athletics track which they leave open during sundays for the public....so much space and the ground isn't rock hard.
the only thing he hasn't got the hang of yet is starting himself off (this bike has a back pedal brake, as well as a hand brake so he can't spin it round to the right place easily).
I would say don't worry about the heaviness, stablisers are a terrible idea and loads of practise, just go everywhere holding him on his bike.
I CAN'T RIDE A BIKE AND I'M 34.
that is why I was so determined that ds would ride and enjoy one as soon as possible.
seeing him going round the athletics track today was vertiginous, I've never been that far away from him in his life before....but he was soooo excited and happy!
