Christmas bike for 4 year old
I want to get my son a bike for Christmas. He's just turned 4, and I sat him on a 16" one at the trek store and it seemed to fit. I'd like it to last a couple of years if possible, but there is nobody it will be passed down to- when he outgrows it, it would have to be sold or donated.
My question is, I've looked at trek, specialized, jamis at the bike stores. They are all around $150.00. Is it really necessary to spend that on a bike for a little guy? I don't care for the little spiderman etc bikes in big box stores, they are just too much, and what if he's not into spiderman 6 months from now. I'd like a sturdy, safe little bike with a bell and a little water bottle. I will spend the money if there's good reason to, but I don't know the difference in quality at this level between say a trek and one of the $30-$60 ones at big box stores (other than looks- liked the trek, the "cars" or "spiderman" bikes at xmart, not so much). I looked at a couple on craig's list and goodwill, but it would be nice to have it at least look new and shiny under the tree, and these did not! I'd like adjustable seat and some adjustment to the handlbars (the trek did have adjustable handlebars).
The specialized was aluminum, not sure about the others. All came with training wheels.
Any ideas on quality differences in 16" little kid's bikes?
