Tern HSD S+ 2023 - Electric Cargo Bike
Enormously Useful. Surprisingly Smaller.
The Tern HSD S+ is a mighty but mini electric bike: 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.
Key Features:
- Tern HSD, 6061-AL frame
- Suntour custom for Tern with 70mm of travel to smooth out the road
- Integrated automatic gear shifting
- Magura brakes offer all-weather stopping power
- Schwalbe Big Ben tyres offer plenty of traction while not affecting rolling speeds
- Sizes: 20” Wheel
- Colours: Shake Polish
- The Tern HSD S+ is available with 0% APR finance
Drive Information:
- Motor: Bosch Performance (Gen 3), max speed 25 kph
- Battery: Bosch PowerPack 500
- User Interface: Bosch Intuvia, 4 mode selectable, walk assist, integrated auto/manual shifting
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.
Automatic Shifting
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.
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.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
