Meet the HSD
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.
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.
Need to carry a kid? Here's how you can safely carry passengers on the HSD.
Bring Your Best Buddy
For many of us, dogs are family too. Build the Doghouse Mini and bring your favorite companion along for the ride.
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.

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.
The HSD can handle up to 374 pounds, accepts one child seat, and works with a variety of cargo accessories for the front and rear for all your commuting and errand-running pleasure.
A Comfier Ride
With a longer wheelbase and extra-low center of gravity, the HSDis 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.
Happiness Shared Daily
The best things in life are meant to be shared, and the HSD is one of them. The HSD resizes in seconds to fit riders from 150 to 195 cm (4’11” to 6’5”) so everybody in the family—from teens to grandparents—can enjoy the ride. The Easy-Step frame design is nice and low for easy mounts and dismounts.
The new Enviolo AUTOMATiQ system does all of the shifting for you, so you can worry less and bike more. All you need to do is pedal. It’ll shift up as you accelerate from a standstill, and shift down when you reach a stoplight. Set your desired pedaling cadence on the integrated Bosch Intuvia controller and let Enviolo do the rest.

Cargo Bike Tough
The HSD gets its genes for strength and durability from the GSD. EFBE Prüftechnik GmbH, one of Europe’s leading bicycle test laboratories, has tested the HSD frame and fork to 170 kg (374 lb) according to their own rigorous Tri-Test standard AND the German DIN 79010 cargo bike standards.
Why the HSD?
Easy-Step Frame Design
The new Easy-Step frame design offers a comfortable upright riding position for riders tall or small, as well as easy mounts and dismounts.
Adjustable Andros stem, Sweep handlebars and precisely engineered Ergon grips combine for a phenomenally comfortable ride.
A custom Suntour suspension fork to soak up all those bumps on your daily ride—and to handle the 170kg load that the HSD is rated to.

Electric Bike Review
Definitely, I'm a fan. [...] I feel like Tern does a really good job with their products, the customer support. And the fact that they have four versions of this bike really lets you dial in.
Die Welt Reiseguide
Why not ditch the car altogether and start the journey on your doorstep? If it's not a round trip, the compact touring bike fits easily into the bike compartments of Deutsche Bahn and the like.
The inconspicuous family organizer—only when the HSD is no longer available does one notice what it accomplishes in everyday life.
And the HSD is amazingly comfortable: the upright seating position ensures a good overview in traffic
The Strategist (New York Magazine)
'The HSD can carry your kid from one year old until they are ready to bike on their own,' Nolte says. 'The bike can easily adapt and change as your family does.'
Both the Tern GSD and HSD passed the new German standard test up to their claimed maximum loads of 200 kg (440 lb) for the GSD and 170 kg (374 lb) for the HSD, which means they meet and exceed the German cargo bike standard.
The stiff frame gives a safe riding feeling, even cyclists over 100 kg should be able to handle the Tern well.
