Tern HSD S8i E-Bike Tundra

Enormously Useful. Surprisingly Smaller.

A compact electric cargo bike that surprises with big-bike capability. The new HSD carries passengers and cargo with exceptional stability, while staying nimble in crowded streets and remaining delightfully easy to ride. Smart, strong, and effortlessly smooth, it’s everything you need from a cargo bike, without the unwieldiness you’d expect from one.

Engineered for Heavy Hauls

HSD carries big without riding big. The latest frame is even stiffer, minimizing flex for a stable, composed ride. Optimized geometry, a longer wheelbase, and a lower center of gravity further improve stability at speed and when fully loaded. Despite being shorter than a regular bike, HSD carries up to 190 kg (419 lb), including 80 kg (176 lb) on the rear rack.

Set It Up Your Way

Supported by a full range of accessories to meet different needs, HSD shifts roles as your life moves along. Carry a child from toddler to teen in any weather, fit an adult friend or partner comfortably in the back, or bring your dog for the ride. Add racks, panniers, or tow a trailer—HSD configures to fit your life, your way.

Share the Ride

A cargo bike becomes that much more useful when it can be shared across the family, and sharing doesn’t get any easier than HSD. With a few quick releases, its cockpit adjusts to fit riders from 150 - 200 cm and up to 130 kg. Ergonomic levers make adjustments effortless, while an upright riding position keeps every rider comfortable.

Space-Saving Design

• Vertical Parking: Your family eBike is best protected from the elements and theft when kept indoors, but space is often a luxury in the city. HSD parks vertically, shrinking to the footprint of a potted plant so it fits neatly into tight corners.
• Vertical Rolling: Who says electric cargo bikes can’t handle tight living spaces? Flip HSD upright and roll it vertically through narrow hallways and into elevators. Vertical rolling makes moving and storing a cargo bike convenient, even in small apartments.
• Flat-Folding: Most cargo bikes are too bulky to load into a car. But not HSD. Its patented Physis Handlepost™ folds down in seconds without tools, turning HSD into a flat, transport-friendly package that fits in the back of an SUV or van with room to spare.
