Product Reviews

Bicycling Magazine Newsletter

The Tern GSD is funny-looking. But use it once, and in short order, you’ll realized its brilliance. Notice I said, “use it” instead of “ride it.” [...] The GSD is a tool, an appliance, a life accessory. It could replace a car for, I’d estimate, over 90-percent of my day-to-day needs.

Süddeutsche Zeitung

With a length of 1.85 meters, at least, it can be steered well and also parked in the garage in any corner. This can even be done upright to save space, because the engineers have designed several "parking feet" at the rear end of the rack, on which the bike can be jacked upright. The handlebars can also be folded away in a few easy steps. Extremely practical!

Bicycling Magazine

Roadworthy additions on the LX and R14 models include a high-/low-beam headlight and, on all models, an always-on brake light that intensifies when you squeeze the Magura MT5 eStop levers.

Die Welt Reiseguide

Why not ditch the car altogether and start the journey on your doorstep? If it's not a round trip, the compact touring bike fits easily into the bike compartments of Deutsche Bahn and the like.
