Find the right e-bike to get you zooming from A to B.
The Tern GSD is unique among e-bikes. It's a cargo bike, capable of carrying two kids or a full load of groceries on the rear rack, but with 20 inch wheels it's no bigger than a 'normal' bike. It's a bike that can be a practical alternative to a car for many trips.
The GSD is a heavy bike, but the Bosch Performance motor makes light work of the weight up hills with assistance delivered smoothly at all speeds. There's space to add a second battery too.
The bike feels reassuringly solid at speed, though its stiff frame and small wheels mean it can feel a bit 'harsh' on rough surfaces. The handling is good at lower speed, which makes the bike easy to handle around the city. The GSD is the most adjustable bike of all we tested, its telescopic seatpost and handlebar meant riders of all sizes could get comfortable.
While it's quirky and costly, and not a bike that'll suit everyone, if you're looking for a bike that can do more than most bikes, this Tern is well worth adding to your shortlist.

Each e-bike was taken on a test route by two riders. The 5km route in and around Wellington’s CBD included city traffic, fast flat roads, hills, kerbs, wooden bridges and a busy waterfront path shared with pedestrians.
We also put the e-bikes through a gruelling 20km route around Wellington’s Wadestown and Northland suburbs. The main challenge was climbing a 2km-long hill five times at a steady 20km/h (a kilometre of vertical ascent) and descending the same twisty narrow road between climbs. It also included a short, steep section of rough path with a narrow barrier negotiated at walking pace, an undulating 5km of suburban streets, and a steep descent requiring brakes to keep the e-bike to the 50km/h speed limit.
Our riding tests, along with a static assessment of the features and functions of each e-bike, were used to score the performance of the motor system and the bike. Overall score includes:
Motor system (50% of overall score)
Bike (50% of overall score)
