This is the d-bike mini wide! I've used it a few times, but it's still in great condition and has plenty of life left. You can adjust the width of the front wheels, making it wider for easier balance when they're young, and then narrower as they get used to it. You can also adjust the saddle height. The instruction manual and tools are included. I plan to ship it in this box, wrapped in plastic. #d-bike #D-bike
