    Tern HSD S8i Active Plus Matte Black


    Enormously Useful. Surprisingly Smaller.

    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.

    Easy to Handle

    Whether you're riding, storing, or moving it around, the HSD is a breeze to handle. It's shorter than a regular bike and its weight is the same as a regular ebike.

    Kiddie Carry

    Bring the kiddo. The HSD's extra-long Atlas H Rack gives plenty of heel clearance and room for your kiddo to enjoy the view rather than being smushed up against your back. The rack is rated to 60 kg (132 lb), so when paired with the right Passenger System accessories, the HSD is ready for your growing family.

    Flat Fold

    Fifteen seconds and the HSD transforms into a flat package that's perfect for fitting into SUVs, station wagons, or bus storage compartments.

    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.

    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.

    A Comfier Ride

    With a longer wheelbase and extra-low center of gravity, the HSD is smoother and more stable than your standard ebike. Easy-Step frame design paired with an adjustable stem and seatpost offers a comfortable upright riding position for both taller and shorter riders. Add a suspension fork and balloon tires and even the meanest cobblestone roads are comfortably navigated.
