Childrens bike sizes

[dubber36]

I was having that over with my cousin who got fitted for a bike last year. The thing is, being a grown up, his geometry won't change, whereas my boy has grown 8" in the last 2 years.

even more so then, u could guess at summat that will fit him for the next 6 months 

taking him in will allow you to get one that JUST fits now with loads of growing room

I'd probably agree with chuff. Take him to a bike shop on his birthday, there will be nothing worse than getting a bike that is the wrong size and he can't go out and ride it when he gets it!

Don't forget you can get small wheels but big frame sizes its a case of trying them out like a pair of shoes, don't go too big as it can dampen there love for riding if its not right.
Just got my daughter a 18" she is 8yrs from a 16" we make sure they get the right size even if it only lasts a couple years, we just recycle them and use the money to buy another one.
My son is 10 and is over 5 foot and wears size 6.5 trainers I'm a 8

Take him to Stan's at the bottom of wyle cop and let him sit on some of the bikes to get a idea of what size would fit him best,they have so many bikes in there you could take him in just to look at the cool bikes without him getting suspicious ,they even have a coffee shop in there.http://www.stanscycles.co.uk
