The John Deere battery-powered Gator has been a great ride-on toy for my boys. They have it at their grandparents acreage and it goes from driveway to gravel to grass with no problem. It has 2 speeds + reverse and there is an electric plug-in to charge the battery when it gets low. They got it when the boys were 3 and 1. They are 6 and 4 now and STILL ride it all over the place. It's worth the extra money for the durability in my book. Just an idea...! Hope you find something that works great for you.
