Lankeleisi RX600 Pro electric mountain bike: test / review
Published on: 05-07-2025 / Modified: 05-07-2025
I started testing bikes about 2 years ago, and the fashion at the time was the big fat bike, preferably with one or two big motors. I see things changing, bikes are getting lighter and Chinese manufacturers are moving more and more towards lighter, less powerful bikes. The Lankeleisi RX600 Pro takes up the codes of the classic mountain bike, adapting the frame to accommodate a battery. Unlike the Duotts C29 I tested last month, this Lankeleisi has opted for perfect integration of the battery into the frame, and has not neglected the finishing touches. This bike is equipped with a 250-watt motor that can be increased to 650 watts. On paper, this may seem insufficient for a bike weighing almost 30 kg, but that's what I'd like you to discover in this test

Unpacking
The Lankeleisi RX600 Pro box is pretty standard and contains the same stuff as the other boxes I've received so far. I did, however, notice a slight difference in the bike's level of protection. Bikes are generally well protected, but this one is even better protected. In addition to the usual foam protection, certain parts of the bike are protected by an extra layer of cardboard.
Assembly presents no particular difficulty, and I might add that the bike's level of finish is so good that everything fits together without the slightest problem. I often encounter one difficulty or another in tightening one part of the bike when I'm assembling it, but that wasn't the case with this bike. Everything fitted together perfectly, without a hitch. I even noticed a sort of notch in the adjustment area that allows the handlebars to be perfectly aligned with the fork, the first time I've seen this on a bike
It takes about half an hour to assemble, including unpacking and the time needed to remove all the protective covers

Overview
The Lankeleisi RX600 Pro is to be classified as an electric mountain bike. There's also a model called the MX600, but this one is to be considered a city bike. The RX600 Pro has a V-shaped frame, a 250-watt motor, 29-inch wheels and a torque sensor. So it's a bike ready for use on European roads, requiring no additional formalities for road use.Frame
The frame is aluminum, there's nothing extraordinary about its format, there's just this Lankeleisi peculiarity with the paint. If you look closely at the frame, you'll see that the paint is pearlescent / metallic, a bit like a fine car body. It may seem like a detail, but this paint plays a role in the bike's aesthetics, and all the feedback I received on this bike while I was testing it was positive.
The bike weighs 23 kg without the battery, so probably around 25 kg with the battery. This is quite similar to the Duotts C29 I tested recently, but with a less powerful motor. The bike can tolerate a load of 200 kg. It measures almost two meters in length and just over a meter in height. The handlebars are 70 cm wide. The bike is perfectly suited to tall people - I'm 1.94 m tall. It's important to understand, however, that even though the saddle can be adjusted in height, if you're very tall you're going to be tilted forward and therefore increase the pressure on your wrists
Handlebar
The handlebars are fairly conventional, with no height adjustment. The gearshift is on the right and works impeccably well, the detent is perfect, and you don't have to look for the dosage of the lever. The brakes are the Zoom type found on many Chinese bikes, and are also well positioned. The grips are rather rough, but I did feel some irritation after riding my first 50 kilometers. This may have something to do with my size, as having to raise the saddle means I'm leaning forward and the pressure on my wrists is greater.
Engine
The motor is rated at 250 watts with a torque of 65 nm. It is capable of delivering 650 watts punctually. I hadn't paid too much attention to the technical specifications before riding the bike for the first time, but I never felt a lack of power. I was convinced that this bike had 600 to 700 watts of power. This feeling comes from the torque sensor, which makes this bike very responsive, and the ability to deliver 650 watts punctually will also erase the power gap
The motor configuration is also a bit special. There's obviously a big difference between no assistance and the first level of assistance, but the difference between the different levels of assistance is quite small. Only the first level of assistance is limited in terms of maximum assistance speed, but from the 2nd level onwards, you receive assistance up to 25 km/h. I'll come back to this point later in the test, because it's a special feature of this bike.
Crankset/Cassette
This bike has a 48-tooth crankset, I haven't received any information about the bearings on the cassette, but the first bearing is quite low. Why is this important? It means that the bike's development will be above average, and with 29-inch reds, this effect will be even more visible. I'll come back to this point later in this test, but riding with 29-inch wheels means that the effort required is greater, the inertia is also greater, but you benefit from better development with each pedal revolution.
The derailleur is a Shimano as usual, it works impeccably well and shifting is fast and fluid.
Wheels
This Lankeleisi RX600 Pro is fitted with 29-inch wheels and Continental Trailking tires. This is the first time I've tested a Chinese bike with tires from this brand. As I mentioned earlier in this article, riding with 29-inch tires offers a development advantage but increases the difficulty. If you're not very sporty, this isn't a big deal, as you have a wide enough gear gradation to find the right level of difficulty for you. For the same conditions (crankset, cassette, etc.), a bike with 29-inch wheels will require 5% more effort
Suspensions
This bike is equipped with conventional front suspension, which is effective but nothing out of the ordinary; it's the same suspension found on many other bikes. What's special about this Lankeleisi RX600 Pro is the rear shock absorber. It's mounted in a vertical position with a support arm integrated into the frame. I'd already tested similar configurations, but with the absorber in a horizontal position. The vertical position offers truly impressive ride comfort, absorbing a large proportion of road vibrations. The cobbled roads I'm used to riding on become much more affordable with this kind of configuration.
Brakes
This bike is fitted with 2-piston hydraulic disc brakes, which are the best available for this type of bike, but it's better to use both brakes at the same time because the rear brake isn't powerful enough to stop the bike quickly enough. It's the same as on many other bikes. It's also worth noting that the brakes are reversed: the left brake actuates the rear brake, while the right brake actuates the front brake.
Saddle
The saddle is quite classic, more or less the same size as the saddle used on other Lankeleisi models. It may be a little wide for a mountain bike, but it provides a good level of comfort. It's not fitted with springs or suspension, but it's still quite comfortable.
Battery
The battery on the Lankeleisi RX600 Pro is probably the same as on the other Lankeleisi bikes I've tested. It's a Samsung 20 Ah 48V battery. It is advertised with a range of 150 km. When I saw the advertised range, I had a little smile because it seemed really exaggerated, but in reality, the range is really good. I had 4 battery bars out of 5 when I went out for the first time with this bike. After riding 58 km, I still had 2 battery bars and was probably on the verge of going down to one. Since I don't use the bike normally when I'm doing my tests, I'm sure I'll have above-average consumption. So, in theory, I should be able to exceed 100 km of range.
Screen/Control
The Lankeleisi's screen can be tilted forwards, and as I know that the brightness of Lankeleisi screens is not always optimal, I placed the screen almost vertically. In fact, this was perfectly unnecessary, as the screen is very bright and offers impeccable legibility even in direct sunlight. The screen is controlled from the handlebar-mounted console, where you can enter the configuration menu. There are ten or so parameters to play with, including the maximum speed for unbridling the bike.
By default, the bike is configured for 29-inch wheels, which is normal given that this is the type of wheel the bike uses. However, this means that the speed displayed is not correct. By changing the wheel size to 27.5 inches, the speed displayed corresponds to the actual speed.
Accessories
Basic bike equipment includes:
- front/rear mudguards
- front lighting (not rear)
- stand
- pump
- mounting hardware
No luggage rack, but I think you can buy one on the Lankeleisi website
The mudguards are made of plastic and are very flexible, which means they'll move around a lot and sometimes make noise when you ride.
Road test
Brake test
To test braking, I used my usual method of climbing to 25 km/h, stabilizing the speed and then braking hard with one brake and then both. Unsurprisingly, braking with one brake is too weak, taking between 3 and 4 seconds for the bike to come to a complete stop. With both brakes, on the other hand, it takes about 2 seconds to bring the bike to a complete stop. With both brakes, the wheels lock up very quickly and end up making the tires squeal on the road.
Speed/acceleration test
To test the different levels of assistance and the resulting speed, I rode the same route with each level of assistance to measure how long it took me to reach 25 km/h. I perform each of these tests with the most difficult speed to put all the bikes tested under the same conditions
0 to 25 km/h per level
1: 9 seconds
2: 9 seconds
3: 8 seconds
4: 7 seconds
5: 7 seconds
As you can see there's not much difference between the different assistance levels. This is quite unusual, so I asked the manufacturer for more details to understand the motor configuration. I've often tested bikes that limit assistance to speeds below 25 up to the last assistance level. This is not the case with this bike: from assistance level 2, you have assistance up to 25 km/h without restriction. The gain in the other levels is therefore marginal, and these levels will only be useful to help you on steep climbs
By way of comparison, here's what I got with the Duotts C29, which has a much more powerful motor:
level 1: 15 seconds
level 2: 13 seconds
level 3: 11 seconds
level 4: 8 seconds
level 5: 6 seconds
There are two interesting things in this comparison:
- the 250-watt motor offers equivalent performance
- the RX600 Pro delivers the maximum faster
The Duotts has a configuration almost the opposite of this Lankeleisi, you have to go to level 5 to get the full power, it's almost the opposite with the Lankeleisi. It's an interesting choice, because it means you'll be able to ride for longer at a low assistance level, and therefore benefit from good range. You'll see that this is confirmed on my rides.
Climb test
To test the effort required for each level of assistance, I always use the same climb (2.5% over 690 metres). I cover this distance without assistance, then with level 1 and finally level 5. I measure ride time, average speed and heart rate. Each run is done at the most difficult speed. Beyond my feelings, I can also compare the bikes on an identical basis.
Assistance level 0
Ride time: 1 minute 57
Average speed: 21,23 km/h
Max pulse: 162
Assistance level 1
Ride time: 1 minute 43
Average speed: 24,11 km/h
Max pulse: 162
Assistance level 1
Ride time: 1 minute 43
Average speed: 24,11 km/h
Max pulse: 162 156
Assistance level 5
Travel time: 1 minute 40
Average speed: 24.8 km/h
Max pulse: 148
This test confirms what I explained in the previous chapter: the difference between Assistance 1 and Assistance 5 is not huge. Journey times are almost the same, but level 5 still allows me to deliver a lower effort, which translates into a lower heart rate.
Here are the times obtained with the Duotts C29:
Level 0 (without assistance):
1:48
167 pulses max
23 km/h average
Level 1
1:53
165 pulses max
21.9 km/ average
Level 5
1:33
145 pulses max
26.7 km/h average
Here again, we see the difference in engine configuration, where the Lankeleisi gives its all from level 1 or 2, while the Duotts wakes up in the last level. The differences between the 2 bikes are therefore not really significant, despite the difference in power. It's just that the last level on the Duotts allows you to reach a higher average speed.
Effort test
I have several loops to test bikes and to test this bike, I took my 32 km loop that I can compare to the Duotts C29 and my racing bike without electric assistance
Lankeleisi RX600 Pro
Lap time: 1:13:32
Max pulse: 170
Average pulse: 153
Average speed: 26.1 km/h
Max speed: 49.6 km/h
Racing bike
Lap time: 1:18:11
Max pulse: 172
Average pulse: 153
Average speed: 24.6 km/h
Max speed: 49.1 km/h
Duotts C29
Course time: 1:15:30
Max pulse: 166
Average pulse: 146
Average speed: 25.2 km/h
Max speed: 44.5 km/h
These results are really interesting because they really confirm what I felt on this course. I found the effort to be greater than with the Duotts, but I was able to reach higher speeds even though the bike had less power. My results were quite similar to those obtained with my racing bike, both in terms of time, speed and effort, but the Lankeleisi saved me 5 minutes on the course time. This means that this bike can offer good performance if you decide to push a little, but it will obviously require a little more effort. I didn't manage to go as fast with the Duotts as I did with the Lankeleisi, but it was the crankset/cassette configuration that made the difference. The Lankeleisi's development is greater, requiring more effort but also offering greater reward. With the Duotts I was almost all the time on assistance level 5, with the Lankeleisi I was mainly on assistance level 2.
These are obviously conditions that don't reflect the daily use of the average man and woman, but pushing a bike as I do (to the best of my ability) highlights the characteristics of the bikes and their effect on the body. You can also take the easy way out, by riding a little slower to save effort and make life easier for yourself.
Suspension test
Battery range
When I received the bike, I had 4 battery bars out of 5, which should correspond to about 70-80% battery. After my first day's ride, I had 58 km on the clock and still had 2 battery bars left. I don't use the bike normally, especially for the first few kilometers when I'm testing acceleration and effort for each assistance level. So this result is really good, and no wonder. The battery capacity is equivalent to that of much more powerful bikes, such as the Lankeleisi Golf X, but with a 250-watt motor you're not going to consume as much energy as a 960-watt motor. So range is clearly a strong point of this bike
With the few extra rides, I can estimate that range will be over 120 km in mixed use, using mainly assistance level 1 or 2. This is probably the best range I've achieved so far. The other 250-watt bikes I've tested have all had lower-capacity batteries, so this one takes the best of both worlds.
Trail test
Conclusion
I've yet to finish editing the video, but I've already given you my conclusion:This Lankeleisi RX600 Pro is a curious beast. It looks like a fat bike, with the same type of frame, the same battery and the same brakes, but it's equipped with a much less powerful 250-watt motor. On paper, it doesn't look like a winner in any comparison, and yet... This bike surprised me on several counts.
I hadn't looked at the technical specifications before testing the bike, and at no point did it occur to me that this bike only had 250 watts. Yes, I did feel that a greater effort was required, but I put that down to the 29-inch wheels and a more demanding crankset/cassette configuration. In the end, the figures don't lie: I got equivalent or even better performance than with a 750-watt bike. Obviously, this comes at the cost of greater effort, but the result is still surprising. A 250-watt bike will undeniably require a greater effort than a 750-watt bike if you want to push it to the limit, but fortunately the configuration is open enough to take advantage of it without getting too tired.
The assistance level configuration is such that you'll benefit from maximum assistance up to 650 watts fairly quickly. Add to this a torque sensor that's quick to react with its 65 nm, and you've got a bike that's responsive and willing despite its lack of power.
Using a 250-watt bike also means you won't have to take any extra steps to get this bike on the road - no need for registration or insurance, the bike's ready to use
Autonomy is another strong point of this bike, because beyond the marketing figures, there's a reality: this is the first bike where I've been able to exceed 100 kilometers of autonomy. That's probably too much for recreational use, as I don't know many people who use their bikes for more than 100 km at a time, but if you're using this bike for long trips, this range will play an important role in your choice. Of course, the range depends on additional factors, but I got over 100 km under normal conditions and without abusing the assistance.
The braking is quite similar to what I've found on other bikes of the same brand, so it's best to use both brakes for ultra-efficient braking.
The suspension is also one of this bike's strong points. I've tested this kind of suspension before, but I think the vertical arrangement of the shock absorber plays a role here. If I stand up on the bike and press down hard, the bike easily takes my 100 kilos and I still feel a good resistance. It's not exceptional in itself, but what surprised me was the low feedback of road vibrations, even cobblestone vibrations are rudely well damped
Lankeleisi has also corrected the screen's brightness deficit, so it's now perfectly readable in bright sunlight
Does this bike have any shortcomings? I'd say the weight is still a problem, for a 250-watt bike I was expecting less. Charging time is still quite long and the plastic mudguards are still noisy when they start bouncing around. The foot position is also rather strange, with the foot pointing too far inwards, so the bike could fall off quite quickly if the ground isn't flat or if it's windy.
To sum up..
This bike is at ease on road and trail, offering you a very good level of riding comfort with a very responsive motor. It will require more effort than a 750-watt bike, but its configuration allows you to strike the right balance between speed and time. Those willing to go the extra mile will be rewarded with a bike capable of outperforming a more powerful bike. And with a range of over 100 kilometers, you'll be able to discover new horizons without tiring yourself out too much
