BERG MOOV MOOV is a unique full-size construction toy for boys and girls ages 5 to 12 years. No tools or help from adults are necessary. The wooden parts, rubber rings, shafts and wheels are multi functional and very durable. Half the fun of the MOOV kit is building a new toy, the other half is riding on it and playing with what you just built! Engineered on the principle that children like to create and play, the MOOV kit encourages children to follow included instructions to build a scooter, go-cart, crane, helicopter, and many other models; or to use their imagination to build a new creation, alone or as a team.
