Hi, I want to get a bike for my little boy for Chrismas. I am not sure what size to get.
He is five and a half years old and cant ride without stabilizers yet.
I took him in
Halfords as I can get a discount there (I know Halfords are not popular on cycle forums) and the guy said he needed a 20inch wheel size but tried a few different bikes with different frames. He said that as long as his feet were flat on the floor when astride the frame then it was ok. He couldnt put both feet on the floor when sitting on the saddle. Is this correct? I dont want to get the wrong size. Any advice?
Thanks
Are you sure you want to get a halfords one... I have had a 20 in Halfords bike in the past... it was heavy... but also badly designed. Look at the height of the seat post and the height of the back tyre. Usually the seat post on a Halfords bike is alot higher than the back wheel. This meant we were unable to lower the saddle enough when the next child was ready to move upto this bike - whereas they could ride all their mates 20" bikes as their saddles went far lower. Eventually we gave up waiting for him to grow into it and bought another 20" bike. (Do you want to buy a 20" Halfords secondhand rubbish bike - I'll do you a good price!!

). At the opposite end ... there was plenty of seat post growth length left in the bike but the handlebars didn't go up very far at all - so it was the design of the bike that caused my child to outgrow it very quickly. Try looking at some other makes of bikes and you will see the saddle will be much nearer the ground.
Sorry I couldn't find very good photos to illustrate the point - but hopefully you will see that other 20" bikes will have much lower saddle heights rather than putting him on a bike that may be too big for him at the moment. The red line on each photo is the approximate top of the seat tube - about 3 inches in difference.
If the handlebars are low ... then they are leaning forward putting alot of weight onto the bars - fine when you are an adult... as a child it makes you more wobbly and harder to lift your hand off the handlebars.
In the 20" size I quite like the Redtail Dawes ... of all the bikes in the bike shed I see.
Also you don't say whether this is suspension or not... its quite hard to buy a kids bike without suspension these days - but they are generally better, lighter and nicer.
And on seat height - if they can't cycle then the child should be able to put both feet flat on the ground whilst sitting on the saddle, and should try scooting without stabilizers to get their balance. Once they can cycle fairly confidently it should be only the ball of their foot touching the ground.
