Plastic, a little difficult to assemble, since the instructions do NOT help at all. Fortunately, the store where we bought it helped us perfectly.

Impressive as a vehicle though, all the children in the square gather around it!!

It is a good construction. It is manufactured in Turkey. It takes a considerable amount of time to assemble if you do not have experience with similar constructions before, because the manual is not detailed with diagrams. The transmission from the pedals to the wheels is average, in fact, I couldn't get both wheels to move, I fixed it 4 times in that specific area, I don't think it's my fault. It can withstand a weight of 50 kg if the child fits, easily, height is the limitation. The rear wheels are plastic and do not have good grip on smooth surfaces.
