Tern offers the D9 in a single frame size intended for riders between 5’1” and 6’1”. The bike includes a long seatpost and a telescoping stem with approximately 9.5” of saddle height and 4.5” of handlebar height adjustment to customize its fit. At 5’11”, I had both points of adjustment set near their maximum, so the advertised height range made sense.
I found the bike generally comfortable; its ergonomic handlebars and rubber grips were easy to hold for long rides. Its saddle was on the slim/firm side, though that was not unexpected considering the bike’s commuter/city bike influence.
The Quick Haul Long’s riding position is forward-leaning (slight to moderate, depending on the handlebar height) with a bottom bracket that felt somewhat shifted forward, so pedaling seemed to require more outward force instead of downward pressure. I found that this took some getting used to, but the adjustment period was short.
As mentioned previously, the bike felt relatively light and nimble for its size; its wide 700 mm handlebars offered controlled steering and its small wheels felt quick to turn.
In terms of features and the user interface, the Quick Haul Long took a minimalist approach. Its small display/control panel occupied the left handlebar while the right hosted the Tektro trigger shifter and a small bell. The bike includes lights and fenders, but no other bells or whistles; this helps to keep its cost relatively low in comparison to other Tern models.
The D9 can be outfitted with a massive range of accessories. For cargo containment, Tern offers panniers, storage compartments, and a front rack or luggage truss. To expand passenger capacity, there are seats, fold-up footboards, handrails, pet carriers, soft weatherproof compartments, and even seat belts!
Something to be aware of: where many of the other cargo e-bikes we’ve tested included basic passenger accessories like seat pads and footboards, buyers interested in the Quick Haul Long will need to add those things separately.
Our test bike included a few of Tern’s optional accessories, including panniers, footboards (called Stow Decks), a storage compartment that squeezes between frame members beneath the battery (the Cache Box L), etc. We appreciated their quality and function once installed, but this process was relatively lengthy and somewhat frustrating.
Critique aside, the Quick Haul Long’s smooth, responsive pedal assist and crisp, ergonomic shifting were highlights of its use. We generally found the bike easy and comfortable to operate.
