It took my husband approximately 45 minutes to put in together with the easy to follow directions provided. The ATV will go in yard, on rocks, up & down hills, and so forth without me having to give it a push. We both love that it is a two-seater therefore he can ride others or his dinosaurs around. If he doesn’t want them beside him, there is storage in the back also. I love that this ATV has a easy to use remote that I can control until he is big enough to drive the car himself. The ATV is very sturdy and safe with an adjustable seatbelt, I hope to use for many more years to come. Also looking forward to using the Bluetooth feature too while he rides. Thank you!
