Abstract: A Detachable Drive Unit for a Snowboard includes a low-profile drive belt assembly designed to be mounted underneath a pre-existing, conventional snowboard, and a drive motor which powers the drive belt for propulsion up snow-covered hills or over variable snow-covered terrain. The device is easily removable, compact and lightweight, facilitating its transport in a backpack, allowing the device to remain with the snowboarder while the snowboard is ridden downhill in a conventional manner.
