[REVIEW] Lankeleisi Kett-8: 35-kg monster surprises with both power and range

The electric bike market has been experiencing an unprecedented boom in recent years, and manufacturers are racing to bring the most interesting and versatile concept. The Lankeleisi brand, which is already a trusted and very popular Chinese maker here, comes with the Lenkeleisi Kett-8 model. At first glance, it may seem like just another of the many “fatbikes,” but this piece combines two seemingly incompatible worlds.

On one hand, it offers a step-through frame with a low standover height, which is more typical of city bikes, but on the other hand it is a true off-road monster with wide 3-inch tires, full suspension, and high-power, high-torque performance with a torque sensor. We put this bike through dozens of kilometers, took it into the city, on bike paths, but also into light terrain and gravel to find out whether those impressive specs are worth it in real life.

Technical specifications of Lankeleisi Kett-8:

Packaging, delivery, and assembly difficulty

The bike arrives in a massive and extremely heavy cardboard box. Just when you receive it from the courier, it will be clear to you that this is not a lightweight carbon racer. Unfortunately, we weren't able to catch the courier, so we had to pick up the packed bike at the depot ourselves.

The box barely fit into our hatchback. Of course, we had to fold down all three rear seats, and without help from a courier company employee, we definitely wouldn’t have loaded it ourselves. The issue wasn’t just the box size, but its weight and the awkward way it’s handled in a car that isn’t exactly the largest.

The interior is well protected with plenty of foam, polystyrene, and tightening straps, so the risk of damage during transport is reduced to the absolute minimum. In the package, besides the e-bike itself, you’ll also find a rear luggage carrier, metal fenders, a set of hex (Allen) keys, a basic lock, an air pump, a charger, and manuals.

If you’re used to the idea that on some e-bikes you just put the front wheel on and you’re good to go, then we need to correct that. Assembling this bicycle took us almost the whole afternoon (with breaks). It’s not that it’s particularly difficult, but there are simply a lot of steps.

You have to mount and properly center the front wheel so the brakes don’t rub against the disc, attach and adjust the handlebars, install the front light, pedal (yes, just one—the other one was already prepared), fasten the chunky fenders (this takes a bit of patience, and during riding you’ll occasionally hear them rattling), put the pedals on, and last but not least fine-tune the brakes. But after an afternoon of hard work, we finally managed to head out in the late afternoon for our first warm-up ride.

Design and ergonomics

In terms of design, Lankeleisi Kett-8 is an absolute magnet for looks. Its interesting, slightly shimmering body (it’s also available in elegant black and aggressive orange) is complemented by very nice black details. The battery with a capacity of 20 Ah is elegantly integrated directly into the thick bottom frame tube, so at first glance the bike doesn’t look like a “mash-up” with an external battery, but instead has very clean, modern lines.

The frame shape is the “step-through” type (without the top frame tube), and it’s excellent—utterly addictive. Thanks to it, you can get on the bike without having to awkwardly swing your leg high over the saddle. You’ll appreciate that when you stop frequently in the city at traffic lights, but also if you, for example, have a fully loaded rear luggage carrier.

The manufacturer states it’s suitable for riders from 160 to 190 cm, and thanks to the adjustable saddle height and the adaptable angle of the handlebar stem, it really does fit. However, the maximum saddle height, in our opinion, might already not be enough for people who are dangerously close to the 190 cm upper limit. By the way, the saddle itself is extremely wide, unusually soft, and therefore incredibly comfortable. Even after dozens of kilometers, your inner-seat muscles won’t protest—something that rarely happens with regular bikes. The maximum load capacity according to the manufacturer is 179 kg.

Lankeleisi Kett-8 weighs more than 35 kilograms. It’s a real heavy-duty tank. If you live in an apartment building, get ready for challenges. Our editorial experience says it all: our elevator, which is smaller—supposedly certified for 5 people—was in reality only a slightly enlarged version of the old three-seater, and for this e-bike it was literally just barely enough room in height when we had to put it on its rear wheel. Hauling this colossal beast up and down the elevator, and especially up and down stairs if needed, is a true sweat-and-drips job. This isn’t a bike you carry into an apartment on the third floor without an elevator.

We also tried transporting it in a car. If you own a regular hatchback, it’s possible, but again, it takes a bit of effort. We got it into our car only after removing the front wheel and fully folding down both rear seats. Into the trunk of an estate wagon or an SUV, though, it’ll be much easier. We managed it ourselves, but with a friend’s help, it’s a matter of minutes—especially when it comes to taking that giant out of the car afterward.

Display and controls

In the middle of the handlebars sits a large, 4-inch color LCD display. It’s beautifully readable even in sharp sunlight and gives you all the key information in one place: current speed, the selected assist level, distance covered (TRIP and ODO), average and maximum speed, and of course the battery status. The controller you use to turn the bike on, switch the lights on, and switch assist levels is located by the left grip.

However, we have to level a smaller criticism. The buttons on this controller are not physical hardware “clicky switches”, but touch panels—more precisely, membrane buttons with absolutely zero haptic feedback. In practice, this means that if you wear gloves or you have wet hands, while riding over a bumpy road you have no idea whether you pressed a button or not until you look at the display. Traditional clicky buttons would do a much better job here. There’s also a button here to trigger a rather loud electronic horn. In the box, you also get a less aggressive traditional bell that you can mount on the bike.

Reality vs. speedometer

During our testing, we wanted to provide the most accurate data possible about range and distance covered. Since, from our previous experience, we know that Chinese e-bikes or scooters often have a tendency to slightly overestimate the kilometers, we decided to measure every single ride in parallel using a precise GPS on Apple Watch.

From our rides, we generated the following GPS data (you can verify them in the attached screenshots): 3.46 km + 9.50 km + 7.96 km + 7.39 km + 42.53 km + 9.18 km = 80.02 km. To this total, we also need to add one more specific ride with a length of 23.59 km (we’ll explain that later in the battery section). So overall, according to precise satellite measurement, we covered 103.61 km.

And what does the speedometer on the bike say? The TRIP counter stopped at 112.1 km. This clearly shows that the e-bike’s speedometer has an error. It overestimates the distance covered (and therefore also the speed) by roughly 8.2%. In the first kilometers, this deviation was the biggest, and later it became slightly more accurate on average. It’s nothing tragic—it’s a phenomenon you’ll see with cars too, but it’s good to know when you brag to your friends about how much you rode today.

Performance and riding

What you’ll get the most from the Lankeleisi Kett-8 is the ride itself. The drive is handled by a motor with a maximum torque of 85 Nm, housed in the rear hub. On paper, it has a power output of 250 W, which classifies it under European legislation as a standard e-bike, but its peak power reaches a staggering 1130 W. And you can really feel it. The biggest difference compared to cheaper competitors is the presence of a torque sensor (torque sensor), combined with a cadence sensor.

In practice, that means the bike doesn’t launch forward the moment you spin the pedals empty—but instead smoothly and intelligently meters out the power exactly according to how much force you apply to the pedals. Thanks to that, the ride feels dramatically more natural, safer, and smoother. It’s like you’ve got superhuman strength in your legs—the bike doesn’t push you by force, but still drives you forward with real impact “pushes”.

By default, the e-bike is locked at the maximum speed 25 km/h from the factory to comply with regulations. Of course, we couldn’t resist, and by using the secret service “M” menu in the section where the display shows “03P”, we removed the limiter—or set the highest offered speed (52 km/h). On the asphalt, we truly pulled it out to a mind-blowing 52 km/h without any problems! At that speed, you really have to show respect and wear a quality helmet.

Our rides covered all possible assistance modes – from 1 to 5. On normal straight roads and cycle paths, mode 3 was more than enough, keeping a very lively pace. The moment we hit steep climbs, we switched to the strongest mode 5. Pedaling uphill on this machine was completely effortless. So the routes we tested weren’t just flat; they often included elevation gain and then a descent back down.

To sum it up: where you’d be sweating blood on a typical bike, on the Kett-8 you can easily overtake out-of-breath cyclists. The Shimano derailleur with 8 gears and a 48-tooth chainring worked reliably and without hesitation. Occasionally a gear didn’t shift instantly, but that’s likely just a matter of fine-tuning the derailleur for a perfect setup.

Suspension

One of the biggest selling points, besides performance, is full suspension. Up front you get a heavy-duty suspension fork with an impressive 120 mm travel and a locking (lockout) option. The real magic happens at the back, where the frame is built as a so-called “soft-tail” with 105 mm travel, complemented by a shock absorber. Combine this with the huge, wide 3-inch KENDA tires and you get an extremely comfortable e-bike that doesn’t make you feel the surface beneath you.

The bike is extremely comfortable. It not only smooths out small curbs and broken city roads, but it also handles gravel and light off-road confidently and beautifully. Forest paths, country roads scattered with stones or roots—you go through them with total ease. The suspension works fantastically, and together with the soft seat and upright riding position, the ride is truly relaxing for both your back and your joints.

Samsung battery, charging and real range

Power comes from a premium 48 V battery with a capacity of 20 Ah, built from branded Samsung 21700 cells. The manufacturer promises up to 150 km in the weakest mode. But what does that look like in our tough real-world testing, where we didn’t ride gently? We unlocked the speed to 52 km/h and rode on hilly terrain—so we put it through its paces.

The bike display doesn’t show exact battery percentages, which we consider a minor downside. You only get a graphic indicator in the form of “matchsticks”. During our testing, we found this indicator to behave in a very specific way. It’s somewhat clunky: when you go into a steep climb and the motor is working at full load, suddenly one matchstick disappears from the display. That’s due to the natural drop in battery voltage under high load. As soon as you ease off the load—stop, or ride on flat ground—the voltage returns to normal and the matchstick magically comes back.

And now the most interesting real-world numbers. We started our test ride with an initial trip exactly 23,59 km long (measured with precise Apple Watch) – we went along a forest road from Košice to Jahodná. After this first route, the battery indicator dropped by the first bar. We then let the bike charge, but we didn’t measure that process yet, since according to the indicator only 1/5 to 2/5 of the capacity was used up.

The real range testing happened only after that recharge. Then came a series of all the other test rides, during which we covered exactly 80.02 km on a single full charge. On these rides, the bike basically ran the battery down almost completely. However, it’s important to emphasize that we rode really aggressively: in steep hills we used the strongest mode 5, and on flat stretches we often rode on mode 3 with the maximum speed unlocked.

Those 80 km really put the battery through its paces. But if you lock the max speed at 25 km/h and use lower assistance levels with pedal help, hitting the 100 to 130 km range is realistic—and this huge Samsung battery will definitely not leave you in the lurch.

After this e-bike had been “worked hard” with 80 km, we decided to fully recharge it and measure the process in detail using a smart plug, so we could verify the manufacturer’s stated parameters. With simple physics, we can calculate the total battery capacity: 48 V multiplied by 20 Ah gives exactly 960 Wh, i.e. 0.96 kWh. As you can see in the attached screenshots from our smart plug, charging a completely drained battery started at 19:15 and finished overnight around 2:00.

So, the whole recharging process took about 6 to 7 hours. The consumption graph shows a stable power draw from the charger at 140 to 170 W for almost the entire charging time, while the output gradually drops towards the end. If we add up the consumed energy for each hour based on the bar chart, we get a value very close to the total of 1 kWh.

After subtracting the usual small losses during charging, this result is absolutely spot-on with the declared capacity of 0.96 kWh. So the manufacturer isn’t lying—and inside the frame, you truly have a genuine battery with exactly the capacity they promise. You can charge the battery inside the bike frame, but it’s even more convenient—after unlocking it with the lock in the frame, you can take it out and carry it upstairs with you to your apartment.

Brakes and night rides with excellent lighting

With a bike that weighs over 35 kg and can reach speeds of 52 km/h, brakes are a critical safety component. Lankeleisi Kett-8 is thankfully equipped with hydraulic disc brakes ZOOM with four-piston calipers. They have a beautifully smooth feel, deliver very precise control, and provide tremendous braking power. The bike stops safely and quickly even in critical situations, and when you squeeze the lever, the motor automatically disconnects.

Another special mention goes to the integrated lighting, powered directly from the main e-bike battery. The front LED light is extremely strong and illuminates the road in front of you really well and broadly in the dark. So you don’t need to buy any expensive external battery packs. The rear light works not only as a position light, but after pressing the brakes it clearly switches on as a brake light. Plus, from the handlebars you can control the integrated turn signals too, which increases your safety when riding in city traffic.

Final verdict

Lankeleisi Kett-8 isn’t for everyone, but for its target audience it’s a dream come true. If you’re looking for an exceptionally comfortable, robust machine that—thanks to its step-through frame—makes getting on easy, and thanks to full suspension and wide tires smooths out even the worst off-road paths, then you’re in the right place. The combination of a powerful motor with a torque sensor and a huge Samsung battery guarantees that hills will stop being a problem and your rides will extend to dozens of kilometers with zero effort.

However, you have to consider that its weight is enormous, and maneuvering it in tight spaces (small elevator, staircase) is literally punishment. But if you have a place to park it safely (garage, basement in the ground floor), it will become your favorite mode of transport. For the price under 2000 euros, you get a full-fledged e-bike with quality workmanship and premium components—something European competitors sell for two to three times the price.
