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.
Keeping your kid dry and cozy is the key to happier rides and fewer complaints. The Clubhouse Fort Mini transforms the HSD into an all-weather solution to carry your little one all year round.
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 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.
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.

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.
Built to Last
Our philosophy is to keep our bikes on the road for as long as possible, not to create disposable products that are built to fail. We start with intentional design choices that make the bike serviceable and safe—and end up with a reliable vehicle you can use day in, day out. Then, we back it up with great local service and a 10-year warranty for peace of mind.
Tough and Tested
EFBE Prüftechnik GmbH, one of Europe’s leading bicycle testing labs, put the HSD through its paces to prove the frame and fork can handle the 170 kg (374 lb) mass gross vehicle weight ride after ride.
UL Tested and Certified
The HSD's Bosch motor system and battery are UL-2849 certified. They've been carefully tested for safety against potential hazards.
Built and Assembled by Experts
Your HSD is carefully built by certified Tern Dealers who will run through a thorough pre-delivery safety checklist before handing over your new bike.
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.

See For Yourself
We could go on and on about how the HSD is a great bike. But nothing beats going for a test ride and finding out what's the best match for you.
Support a Local Business
Your local bike shop is one of the essential businesses that hold your community together. But there are several other reasons why you should buy local.
If you need a cargo e-bike that can haul a lot but do it in a smaller, more nimble size, this is your best bet.
Electric Bike Report
Our pick for the best city bike of 2022 looks a lot like the dense urban areas it was built to thrive in: There’s no wasted space. The Tern HSD S11 is a compact electric city and commuter bike designed with functionality and utility in mind.
The Tern HSD could almost carry twice our test rider, so high is the maximum payload.
A full 170 kilograms of permissible total weight, and a rack with a load capacity of 60 kilograms alone plus trailer option make the bike ready for the really big tasks.
My life has changed because of Tern. Every day I am on the road by bike. I am more relaxed, and experience the seasons in the city consciously. My "little all-rounder" is the ideal companion for women who are active in life and lead a sustainable lifestyle.
Electric Bike Report
The amount of thought Tern has put into their bikes really is astounding and it’s hard to look at the HSD and not wonder how they managed to fit so much utility, so much practicality into such a small e-bike.
Automatic shifting is an obvious choice for an everyday e-bike. The multi-purpose and compact Tern HSD S5i now has a new version with the 5-speed Shimano Nexus Inter-5E hub.
The Tern HSD S5i is an excellent family cargo bike in a compact size. The new five-speed automatic gearshift proves incredibly practical, especially in city traffic, and makes for a casual riding experience.
