Product Reviews

ElektroRad

Ingenious all-rounder for city & country.

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.

Cyclinfo

The loadmasters among bikes need a lot of space. Not so with the HSD, because it can be stowed vertically on its end.

Gear Patrol

For those with limited space, Waldman suggests the excellent Tern HSD. Yes, it’s a folding e-cargo bike — with room for one kid or a family grocery haul — that can be stored vertically to take up minimal space.Read more

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
