The Garage Dolly rides on sturdy 4-inch wheels, so it will roll or swivel easily, and will even navigate cracks, crevices, and pitted garage floors. The Dolly is made from sturdy aluminum and steel and only weighs 68 lb. When not in use, it folds and can be mounted on a garage wall for storage. The Garage Dolly has a load rating of 1300 lbs. It measures 90″ long (expandable to 94″) and has a deck dimension of 12″ wide. It is 24″ at its widest point at the wheel brackets. Four large twist-down brakes, (along with having the wheels down as well) secure the unit from rolling when placing your bike into the Dolly, or removing it.
