It's push-powered, with an inner friction-powered flywheel. Make a couple of brief pushes while holding the truck, then allow it go to have it run to the construction site.
There is a dump-truck bed that can hold a little cargo. The bed lifts up to allow the cargo slide out and kids could ride ahead!
In general a sharp-looking truck for the sandbox and using.
Priced to sell promptly, only $19.
