Mighty But Mini

The HSD is the right amount of bike if you want the benefits of a cargo bike but still fancy the convenience and handling of something less bulky. Lean and nimble, the HSD is shorter than a regular bike yet capable of hauling a max gross vehicle weight (MGVW) of 180 kg (397 lb). And thanks to best-in-class components, rigorous lab testing, and UL 2849 certification, you can count on having a safe, reliable bike.

Haul With Confidence

The compact HSD electric cargo bike stuns with its heavy-hauling abilities. Load up on groceries, carry a furry friend, or make extended errand runs without worrying about overloading. A long wheelbase and extra-low center of gravity ensure easy handling and stability, even under load. The HSD is more than enough bike for reliable urban hauling.

Room for a Friend

Transform daily trips into exciting adventures by having a +1 tag along. And not just with your little ones. Rated to 80 kg, the sturdy Atlas H Rack is long and spacious enough to easily accommodate an adult passenger. And there’s a wide range of accessory choices to ensure a safe and comfortable ride. Weekend picnics and date nights just got a lot more fun!

Designed for Sharing

The HSD fits riders 150 – 195 cm tall (4’11” – 6’5”), and the cockpit adjusts in seconds to suit your riding position. It also makes it simple and easy to share the bike with family members. Smaller riders will also appreciate the low Easy-Step frame design for effortless (dis)mounting.

Smart Security

The HSD’s smart electronic lock activates automatically when you park, disabling the e-bike system and helping prevent theft. Your smartphone serves as the no-fuss digital key for unlocking the bike. S-Class models also include a high- decibel alarm with flashing LEDs to deter tampering, along with text notifications and GPS tracking in case the bike moves significantly.

More Power to You

Tackling steep hills and accelerating from a standstill loaded down with extra cargo just got a whole lot easier. Featuring the new Bosch Performance Line motor, the HSD now delivers up to 50% more torque compared to some previous HSD models, along with 340% pedal assistance. A new Auto mode can also sense deceleration on a climb and automatically compensate with extra support.

Easy to Ride

The size and weight of big cargo bikes can be intimidating. But the compact HSD was designed to be much more inviting. It’s easy to ride, just like a bike should be. Even when fully loaded, a long wheelbase, low center of gravity, and stiff frame provide enhanced stability and handling. And the low Easy-Step frame design makes it easy to mount and control the HSD at a standstill.

Tailored to Your Life

The best kind of cargo bike is the one set up with the right gear to fit your needs. No matter if you’re looking to safely carry a child in all types of weather, comfortably carry an adult or pet, or haul all different types of cargo, the HSD has an extensive ecosystem of accessory options that can best suit your needs today, and as they change in the future.

Stress-Free Parking

The compact HSD easily fits in spaces where other cargo bikes don’t dare go. Navigate through hallways and in tight urban spaces. Flip it up vertically to easily fit in elevators. Use vertical parking for hassle-free storage next to a potted plant. Remove stress and worries about finding parking near home or work.

Hit the Road

A cargo bike should help expand your life, not restrict travel to your home base. With the compact HSD, you can venture out to more open spaces. Fold the HSD down flat in seconds to fit in an SUV or RV to journey where life takes you. Or board a train with the HSD and depart for even more cargo bike adventures.

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.

Tested for Safety

The HSD frame, fork, and handlepost were designed and built to handle a load of 180 kg (397 lb). And we turned to EFBE Prüftechnik GmbH, one of Europe’s leading bicycle testing labs, to put the HSD through its rigorous Tri-Test to prove the HSD could handle the stated load, ride after ride.

UL Tested and Certified

The HSD’s Bosch e-bike system is certified to the UL 2849 standard, the most rigorous e-bike electrical test on the market. The battery, charger, motor, and display are each tested for safety against potential electrical system hazards, as well as tested together for system safety.

Tuned by Professionals

E-bikes are complicated machines that require attention and service by trained professionals. So the HSD is only sold through Tern-authorized local bike shops, to guarantee your HSD is assembled and tuned by experienced professionals, and that you’ll always have a place to go for periodic service and maintenance.
