SMARTONE MICRO is super easy to collapse and ready to use in less than 2 minutes. We developed a list of details which can improve the quality of usage like small transport wheels, props and deflects. Compact size allow the cart to transport easily all parts in one case. Only three from 220mm diameter wheels fits inside the collpased cart. We add a special bag to which you can fit the remaining wheel or all four wheels.
