[Closed] BMX for kids - help please!

Hiya,

My kids ride MTBs and have done since day dot. They are now just starting secondary school and I don't want them riding their proper bikes around town for various reasons (security / maintenance etc) but they love their bikes and I want them to be able to ride and go work on their skills without me.

They have a few quid birthday money saved and I'm happy to help them so can someone give me some pointers into this alien world? Where should we be looking? How does the sizing work? What is good & what is bad?

I have no idea.

The kids are about 150 tall and on small 15" adult bikes with 26" wheels and forks on MTBs if that helps at all.

Thanks.
