I’m looking for a kids’ bike for my 3 y.o. baby. I try to choose something from https://www.bikethesites.com/best-kids-bikes/. If someone has experience choosing a bike, please share. How did you choose the seat and height of the bike? I would be very grateful. Thank you!
You can find charts online indicating which size you need for the height of your child, I found those very useful.
I’d never buy a bike online though. I think it’s important to have your child try out different bikes and seats, to see what suits them, what they think is comfortable etc.
