Start from the riding you actually do
Every other decision rests on a single question: how and where do you ride? The bike types each maker lists answer it before any specification does. KALKHOFF lists city, hybrid and step through, so its city bikes sit alongside a wider spread of frame types rather than standing alone. Tern narrows to cargo, commuter and folding, which puts a load carrier and a folder in the same family. HK BEIRUI TRADE CO. spans commuter, folding and fat tire and confirms that folding designs are part of its offer. Start from the commuter and city e-bikes ranking, then check that the category matches your route before reading a single price.
The type list also hints at where a brand's engineering and parts focus sits. A maker listing cargo and commuter types is likely to publish load and weight figures you can compare, while one listing fat-tire types is chasing a different buyer with different priorities. Hold your own weekly route against each list, because the type you need narrows the field before price does.
Price, and what the money covers
Prices across the listings held here run from €175.38 to €5,999 at the entry end to €599.99 to €14,000 at the top, in euro. Neither figure tells you what you get, so pair the price with the motor behind it. Nominal power in this data set spans 250 to 2,000, and that spread is the clearest single reason two bikes at a similar sticker can feel very different on the road.
Model names make the comparison concrete. KALKHOFF's reference bikes are IMAGE 3 MOVE, Endeavour 5+ Move, Entice 7+ Advance ABS, while Tern lists GSD R14, Quick Haul D8, HSD P10e, Vektron P7i. A shortlist of names from one brand lets you compare several frame styles at a similar specification level, which is a fair way to see what a given price buys in geometry, motor and equipment before you visit a dealer.
Assist class sets where you are allowed to ride
Check the assist class before weight, range or price, because it decides where the bike is legal for you. KALKHOFF states EU 25 and Tern states EU 25, so both sit in the same class and can be compared on equal terms. HK BEIRUI TRADE CO. states us class 2, a class shaped for a different market's rules.
If your local limit matches the first two, the comparison stays straightforward. If it matches the third, a bike from the other two may need a different class or a version built for your market. Have a dealer confirm the class on the exact model you intend to buy, not just on the range, before you commit any money.
Motor, position and drivetrain
Both KALKHOFF and Tern name bosch as their motor brand, and both place it at the mid of the frame. That shared setup is worth knowing, because servicing familiarity and parts supply often follow the motor rather than the frame maker. The KALKHOFF review is the page to read for how that base is shaped into finished bikes.
The drive system matters just as much for a daily rider. KALKHOFF lists belt drive, and so does Tern on its listed models. A belt keeps chain oil off your clothes and cuts the weekly cleaning routine, which counts on a bike you ride in office clothes. Weigh that against the cost of a belt replacement when you compare service cover, since a drive system you cannot service locally soon becomes an argument for a different brand.
Range claims and battery size
Range is the number most often quoted and least often comparable, because each maker states it under its own conditions. Tern gives a largest battery of 1,600 with a claimed range of 288. HK BEIRUI TRADE CO. lists a largest battery of 1,800 alongside a claimed range of 129. The Tern review is a good place to see how a quoted figure sits against real use.
Treat each pair as a single claim rather than as two separate numbers. Larger capacity should support a longer quoted range, so where the capacity gap is wide but the claimed ranges sit close together, the claim has probably been measured on gentler assumptions. To size a real commute, compare the claim against the distance you cover in a week, including the return leg and winter conditions, rather than against a single best-case figure.
Load, weight and stopping
A city bike is a carrying machine, so the load rating often matters more than the range figure. Tern publishes a maximum payload of 210 and a lightest listed weight of 22.8, and those two numbers together tell you whether the bike suits a heavy rider, a child seat or a weekly grocery run.
Brakes narrow the field quickly, and hydraulic disc brakes are the sensible default for a bike sharing a path with buses, vans and pedestrians. Tern lists hydraulic disc brakes, as does HK BEIRUI TRADE CO. on its listed models. Tern also holds ul 2849 certification on a listed model, so check whether the standard matters to you is stated for the specific bike rather than assumed from the brand. The HK BEIRUI TRADE CO. review covers the rest of that picture.
Warranty, servicing and where you buy
Cover is what you notice years later. KALKHOFF offers a frame warranty of 10 years and Tern matches it at 10 years, with a money back window of 14 days from KALKHOFF. Both run servicing through a partner setup, so the practical question is how many of those points sit within a sensible ride of your home or office.
How you buy differs. KALKHOFF sells both, so you can ride one away and order yours, while Tern sells through a dealer model where fitting and handover happen in person. Support matters as much: KALKHOFF reaches buyers through email, phone and help centre, and finance is available from both KALKHOFF and HK BEIRUI TRADE CO. A dealer-backed handover also settles the assist class question in section three on the spot.
Background helps you read the rest. KALKHOFF was founded in 1919 and is run by Kalkhoff Werke GmbH in DE, with listed markets DE. Tern was founded in 2011, and HK BEIRUI TRADE CO. is registered in HK. A long history usually means a wide parts library, while a younger maker may be quicker to answer. Decide which of those suits you, then return to the commuter and city e-bikes ranking and narrow the list with every answer filled in.
