Fisher-Price Toddler Tricycle Hot Wheels Tough Trike, Toy Bike with Handlebar Grips & Storage for Outdoor Play Kids Ages 2+ Years

I am trying to assemble it. On step 5, when i am trying to tap the wheel cap with hammer, it is not fitting in. Please help.

how tall does a toddler need to be? I've only seen ones my toddlers 34 inch tall total can't reach petals and roll thier feet and ankels under back

Will this work for a 3 year old or is it more for younger kids?

What is the weight limit for this bike?
