The Full Scoop

  • The HSD is mighty but mini: It's easy to handle, easy to share, extremely comfortable to ride, carries a whole lot of cargo—and all of this in a compact design that's shorter than a standard bicycle. Fifteen seconds and the HSD transforms into a flat package that's perfect for fitting into SUVs, station wagons, or bus storage compartments.
