Ah, I was going to suggest a 26″ hardtail, but looks like he’s surpassed that.
My 4′ 8″ lad just moved from a Nukeproof Cub Scout 24″ as I managed to grab the 26″ version at Xmas, before the end of an era 🙁 Absolutely love it, awesome bikes! Perhaps there’s a few out there?
He’s also got his eyes on his Mum’s 5010 – perhaps a Small one of those if you can find one?
chambord – we’ve got the grey Nukeproof 24″ that, as of last Saturday, is up for sale. South Yorks, am up in the Dales quite a bit and Lakes some times so drop me a line if you are interested and don’t want to go for postage from hooja.
