Vertical Parking

The HSD flips up for convenient vertical parking. Take it upstairs in an elevator and park it inside at home or at work—it needs just a wee bit of floor space.

Ready to Haul

Despite its diminutive stature, the HSD is a mid-sized cargo bike with some serious hauling capacity. With a maximum gross vehicle weight of 170 kg (374 lb) and an XL-sized Atlas H Rack, it'll carry a week's worth of groceries or camping equipment for the weekend. It even has a dedicated trailer mount, so adding extra cargo is a cinch.
