>>1950822as for brands who cares just get them a bike without a coaster brake
sonething simple like a bmx style bike is great theyl just zoom around and have fun
if their a little older get them a mountain bike with a front brake and some gears so they can learn how to use those properly
and dont forget to set their seat height properly once their confident at riding
i grew up riding with the seat slammed and then when i started riding kids and adult mtbs i kept doing that because it felt natural to me
it wasnt untill i was in my 20s that i actually learned to ride with the seat set correctly and it took a while to get used to
teach them how to use a screwdriver and spanner and how to change toobs and stuff too
get them into the mindset of self sufficiency yknow
theyl thank you when they grow up and are using a bike as transport
