Sizing Guide


The Full Scoop on the Tern HSD S8i

  • The Tern HSD S8i 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 Tern HSD S8i transforms into a flat package that's perfect for fitting into SUVs, station wagons, or bus storage compartments. Despite its diminutive stature, the Tern HSD S8i 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.  The Tern HSD S8i resizes in seconds to fit riders from 150 to 195 cm (4’11” to 6’5”) so everybody in the family can enjoy the ride. The Easy-Step frame design is nice and low for easy mounts and dismounts.
