Product Reviews

Despite compact dimensions and small 20-inch wheels, the Tern can be loaded up to 200 kilos total weight. The fact that it does not seem overloaded or unstable even then speaks for the solidity of the frame.

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.

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!

Süddeutsche Zeitung

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.

It's small, yet it's big: Tern's versatile e-bike is no longer than a regular electric bike, yet it serves as a family car, shopping cart and van.
