Need a child bike seat for a big 3.5yo.

[minko]

We have one but it's only suitable for a smaller child and he was always jammed up against my backside poor child.

Can anyone recommend one for a larger child please?

bike seats go up to 18kg so may be near that weight anyway. We bought a trailer for our bike it was easy to move between bike could fit two children and picnic ect. We are now looking at getting a tag o long as out youngest 4.5 can ride a two wheel bike. Due to the fact she had a balance bike. Hope this helps
