Enormously Useful, Surprisingly Smaller: Tern Launches the HSD

Enormously Useful, Surprisingly Smaller: Tern Launches the HSD

Frankfurt, Germany, July 9, 2019 — Micromobility specialist Tern today unveiled the HSD, an urban ebike that is mini but mighty.

"Many ebikes on the market look like standard bikes with motor systems and batteries wedged in," stated Josh Hon, Tern Team Captain. "We started the HSD project with the goal of designing a better, more useful, ebike. That meant wiping away pre-conceived notions for things like frame design, riding geometry, and wheel size. The result is the HSD, a small bike that is just much more useful."

Easy to Handle

Only 170 cm long, the HSD is shorter than a regular bike. It's a breeze to handle in tight spaces and goes easily where other bikes won't. The HSD flips up for convenient vertical parking and elevator rides, and can be flat-folded in seconds to go into bus racks and SUVs.

Ready to Haul

Despite its diminutive stature, the HSD is a mid-sized cargo bike with serious hauling capacity. With a maximum gross vehicle weight of 170 kg (374 lb) and an XL-sized rack, it'll carry a week's worth of groceries or camping equipment for the weekend. It even has a dedicated trailer hitch mount, so adding extra cargo is a cinch.

The Atlas H Rack is rated to 60 kg (132 lb) and compatible with many different child seat brands, including Thule Yepp and Bobike. An upcoming Passenger Kit will allow riders to continue carrying their kids as they grow older.

Comfier For Everyone

The HSD resizes in seconds to fit riders from 150 to 195 cm (4'11" - 6'5") so everybody in the family—from teens to grandparents—can enjoy the ride. The new Easy-Step frame design offers a comfortable upright riding position for riders tall or small, as well as easy mounts and dismounts. Paired with an adjustable stem and seatpost, a suspension fork, and balloon tires, the HSD delivers a smoother and more comfortable ride even on the meanest cobblestone roads.


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 upcoming EN Cargo Bike standards. In addition, the HSD is equipped with several safety features that make it ready for almost any situation: integrated front and rear lights, hydraulic disc brakes for all-weather stopping power, puncture-resistant tires, and even reflective decals.

Powered by Bosch

The HSD is powered by Bosch's next generation Performance Line or Active Line Plus motors. The motors are smooth, silent, and deliver power with a wonderfully natural feeling. And of course every motor and battery system is backed by Bosch's best-in-class warranty and service.

A Whole Lot More

On top of all the standard features mentioned above, different HSD models are also packed with extras like Gates belt drives, Abus keyed-alike frame locks, and Cane Creek Thudbuster suspension seatposts. The top of the line S+ model even features automatic shifting.

"In the last two years, we created the Vektron and the GSD, both of which excel in their categories," says Eric Lin, Director of Product Development. "But there's this third category, an ebike designed not for the niche but for almost everybody. It doesn't fold to a tiny size or carry 200 kg, but simply does the standard stuff better. Finally, there's a bike that you and I will want to use daily, a companion for greener transportation. The HSD is the future of urban ebikes, now.”

The new lineup includes the HSD P9 starting at €/$3099, HSD S8i starting at €/$3699, and HSD S+ starting at €/$4999. Bikes will be in shops in Q1 2020. The HSD will make its first appearance at the Urban Mobility Media Days on July 10-11 in Frankfurt and follow at Eurobike in September.
