DS1 is four and has never been particularly into bikes, or rather, wasn't very interested in his trike when he fit it (or his scooter), so we hadn't gotten him a bigger bike. But we're now thinking it would be good for him to learn how to ride and a good way to keep fit.
DH and I also plan to start riding again. DH has a bike, I'm getting one.
I was thinking of just getting myself and DS1 bikes from BigW or the like, but DH wants us to go to a bike shop and get "proper" bikes. I'm not sure it's worth it considering we'll be paying double the price and I'm not sure how much difference there'll be - or how much DS1 will use it for that matter (though I suppose DS2 will eventually if he doesn't).
Where did you get your bikes? Or your kids bikes? What was the quality like? If you paid more was it worth it?
