My son is almost 6 but very tall for his age - 130cm at present, over 99.6th centile - so more like an average 8 year old. He's very much grown out of his 16" wheeled bike but seems to be between 20 and 24" bikes.
Can anyone offer any guidance based on experience of similar height kids - according to Isla, the Beinn 24 is from 127cm but I note that other brands seem to size bigger with 130 or 135 being the cutoff for a 24" wheel bike.
I don't really want to get a 20" bike now and in less than 9 months (based on the height charts) be needing a 24" one but at the same time I don't want him to not enjoy riding his bike this summer because it's too big for him. Then there's the cost - Mrs Clubber isn't going to sign off on a £350 bike (the Isla) and second hand ones go for silly money and seem pretty rare around where we live anyway.
FWIW, he rode a Spesh Hotrock 24 and he can ride it but it does look big for him, particularly the height of the front end.
So, alternatives? Most others seems fairly heavy (you get what you pay for I guess) though I see plenty of kids happily riding them so maybe need to get away from my own thoughts on weight.
Also, the Hoy bikes looks good - slightly cheaper than the Isla bikes but look like they're well designed and spec'd - anyone had one for their kids?
