Just order one online. It will save you a lot of time. I had the same issue as you when I was looking for a bike for my 5yo son. I wanted to find a good bike, spent a lot of time for nothing. I was confused since I wanted something good for him. In the end, after numerous searches in the shops, I decided to go online. I found this site cutelittledarling.com, read some reviews, and ordered the bike model that I needed. The main lesson of this story is that online shopping is the best. Just make sure that the refund policy is working well.
