MyBike

The HSD S+ combines the advantages of a cargo bike with a compact design

The new 2020 Tern HSD was the CyclingTips team bus for Eurobike. I’d ride this the 12km or so between Eurobike and our accommodation, loaded with everyone else’s bags and gear. It’s quite impressive just how much stuff this can carry.

Electrek

The HSD comes in multiple flavors designed to hit a wide range of price points. The most advanced version even offers automatic shifting thanks to a new partnership with Enviolo.

Elektrobike

With the new HSD, Tern has created an interesting e-bike which forms a convenient combination of compact dimensions and high load capacity—and which rides harmoniously and comfortably.

New Atlas

The Tern HSD S+ is designed to be so uber-practical that it could replace your car.Read more

WIRED

Tern’s small, fat wheels and low rack means that it has a much lower center of gravity than the average electric cargo bike. It’s also shorter than the average road bike, which makes it much easier to maneuver and to store.Read more

Cycling Industry News

The urban transportation brand is one of seven exclusive launch partners to offer Automatiq in the model year 2020.

Bike Rumor

The new HSD is the smaller sibling to the dual-battery GSD e-cargo bike, opting for a smaller footprint in your garage and livelier feeling ride.
