Product Reviews

My life has changed because of Tern. Every day I am on the road by bike. I am more relaxed, and experience the seasons in the city consciously. My "little all-rounder" is the ideal companion for women who are active in life and lead a sustainable lifestyle.

ElektroRad

A full 170 kilograms of permissible total weight, and a rack with a load capacity of 60 kilograms alone plus trailer option make the bike ready for the really big tasks.

ElektroRad

But what surprised me most is how much this bike has improved my everyday life. I know what you’re thinking. An eBike? In a city as flat as Melbourne? Is that really necessary? Fair enough. But trust me, you think it won’t make a difference – until it does.

Broadsheet

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.
