Lankeleisi RX800 Plus 2025 Review: Complete Guide to Performance and Features

The Lankeleisi RX800 Plus is a machine built for riders who have outgrown the idea that an e-bike should be polite. With a 1000W brushless rear hub motor, a 960Wh Samsung 21700 battery pack, and a full front-and-rear suspension platform sitting on 20” × 4.0” fat tires, this is Lankeleisi’s answer to what happens when you prioritise off-road capability and payload capacity over kerb weight and urban compliance. The 2025 version brings one upgrade that changes the ride character more than any spec sheet number suggests: a torque sensor replacing the cadence sensor of earlier units.

Lankeleisi RX800 Plus 2025 Review: Design and Build Quality

Frame and Construction

The RX800 Plus uses a 6061 aluminium alloy frame, hot-treated for corrosion resistance and finished in electrostatic paint. The welds are deliberately heavy — this is a bike that prioritises structural integrity over visual refinement — and internal cable routing keeps wiring protected from trail debris and rain. Frame geometry accommodates riders from approximately 165 cm to 195 cm. The overall stance is wide and upright, partly a function of the 20” × 4.0” tire footprint and partly a deliberate choice for stability on the terrain this bike is designed for. The battery sits removably within the downtube, key-locked and extracted from the underside — far more practical than non-removable integrated designs. Compared to the Lankeleisi MG600 Lite, which integrates its pack into a sealed frame section, this is a genuine daily-use advantage for riders who charge away from the bike.

Battery Integration

The 48V 20Ah Samsung 21700 battery is housed within the downtube and secured with a key lock. Unlike frame-integrated non-removable packs, this one slides out from the underside — useful for apartment dwellers who park the bike in a storage room without a nearby power socket. The Samsung 21700 cell format is a step up from the 18650 cells used in many competing fat bikes: higher energy density per cell means more capacity in the same physical volume, and Samsung rates this pack for over 1,000 charge cycles before meaningful capacity degradation begins. Charging from empty takes approximately 6–8 hours with the supplied charger.

Suspension System

Full suspension is standard on the RX800 Plus, not a premium option. The front fork uses oil pressure with a lockout lever — useful for conserving energy on smooth tarmac sections where suspension bob wastes battery. The rear is the more interesting specification: the DNM-38RC air shock absorber offers independent adjustment of both damping rate and air pressure. Riders tune the rear to their weight and to the terrain — locked out on a canal path, fully open for forest singletrack, somewhere between for mixed surfaces. That level of adjustability normally adds €300–400 to comparable bikes at this price tier. The 20” × 4.0” fat tires add a further compliance layer on top of the suspension itself: at 10–15 PSI for trail use, wide-volume tires absorb small impacts before they ever reach the chassis.

Safety Features

Hydraulic oil disc brakes with 180mm rotors handle stopping front and rear. Both brake levers carry motor cutoff sensors — squeeze either lever and drive cuts instantly, no overlap between motor output and braking. The integrated lighting system pairs a 4.5” circular LED headlight rated at 780 lumens with a 95 dB electronic horn built into the same housing. A rear taillight activates independently. For a bike at this weight and potential speed, 780 lumens is adequate for off-road riding at dusk and visible enough for road crossings.

Lankeleisi RX800 Plus 2025 Review: Technical Specifications

The standout specifications of the Lankeleisi RX800 Plus 2025 — a 1000W motor producing 80 Nm of torque and a 960Wh Samsung 21700 battery — make it suited to heavy terrain, steep climbs, and riders who need genuine all-weather all-surface capability.

Lankeleisi RX800 Plus 2025 Review: Performance

Motor and Power Delivery

80 Nm from a rear hub motor is a number worth pausing on. Many mid-drive e-bikes in the €2,000 range produce 50–65 Nm — the RX800 Plus hub motor outpunches them on paper, and confirmed testing on steep gradients shows it attacks 35% inclines without hunting or stuttering. The 2025 torque sensor is what makes that power usable: it reads the force applied to the pedals and scales motor output proportionally, so harder pedalling on a climb produces more assist automatically, without touching the PAS controls. Earlier versions of the RX800 Plus shipped with a cadence sensor, which detected rotation speed but not force. The difference in feel between the two systems is significant on variable terrain — not a marginal improvement, a meaningful one.

Five PAS levels cap at 25 km/h in EU-compliant configuration. PAS 1 holds around 12 km/h — useful for technical sections where control matters more than speed. PAS 5 reaches the legal ceiling within a few pedal strokes on flat ground. The star gear design Lankeleisi uses internally reduces drivetrain noise and improves motor efficiency at partial loads, which contributes to the 150 km maximum range claim.

Battery Life and Range

The 960Wh Samsung 21700 pack is rated for over 1,000 charge cycles. Real-world range on mixed terrain — forest tracks, gravel, some pavement — lands between 80 and 110 km at moderate assist levels. The 150 km maximum assumes PAS 1 or PAS 2 on relatively flat ground with a lighter rider; that is a different scenario from what most buyers will experience, and realistic range expectations should reflect that. For typical weekend trail sessions of 30–60 km, the battery is effectively inexhaustible at any assist level. The removable pack is the practical advantage that separates the RX800 Plus from the non-removable integrated battery of the MG600 Plus — charging off the bike wherever a socket is available.

Climbing and Terrain Handling

This is where the RX800 Plus earns its spec sheet. The combination of 80 Nm torque, 4.0” tire volume, and full suspension keeps the rear wheel planted on surfaces where a hardtail breaks traction — wet roots, loose sand, soft mud, chunky gravel. The Shimano Altus 7-speed gives adequate gear range for sustained climbs without relying entirely on motor assist, which matters for battery preservation on longer mixed-surface routes. One practical note before the first off-road session: the derailleur guard is absent on some units. Adding one costs very little and prevents a repair that would be expensive and inconvenient far from a workshop.

Lankeleisi RX800 Plus 2025 Review: Comfort and Handling

Ride Quality

Full suspension on a fat bike is more comfortable than most riders expect at this price point. The front fork’s oil-pressure system handles impact absorption from roots and rock steps; the DNM-38RC rear unit deals with the sustained vibration fatigue that accumulates over long off-road rides. Testing a comparable fully-suspended fat platform on a three-hour forest session last autumn — terrain that would have been genuinely unpleasant on a hardtail — the difference was not subtle. Hands and lower back arrived intact rather than ground down. The 4.0” tires at 10–15 PSI add compliance on top of the suspension, so small impacts arrive at the chassis already softened.

Ergonomics

The handlebar position is upright and wide, suited to the bike’s off-road character — weight sits slightly rearward, improving rear traction on climbs and giving confidence on descents. The saddle is well-padded for rides under two hours without adjustment; for longer distances, saddle preference varies enough that swapping it is a reasonable first upgrade. The quick-release seatpost means height adjustment takes seconds, which matters on a 40 kg bike where fine-tuning before a ride is the only convenient opportunity.

Weight and Maneuverability

39–40 kg is heavy, and that number will not improve meaningfully. Loading this bike onto a vehicle rack requires a second pair of hands; carrying it upstairs is not a casual task. On the move, the weight largely disappears — the suspension, fat tires, and motor combine to create a ride that feels planted rather than sluggish. The honest advice: plan storage and charging logistics before purchasing, not after. For riders who want full-suspension trail performance in a lighter, narrower package, the MG600 Pro runs 29” trail geometry at lower mass with different terrain trade-offs.

Lankeleisi RX800 Plus 2025 Review: Braking and Safety Systems

Hydraulic Braking

The hydraulic oil disc brakes with 180mm rotors stop the RX800 Plus effectively from the speeds a 1000W motor makes routine on descent. Hydraulic actuation means consistent lever feel regardless of temperature — mechanical cable brakes degrade noticeably as conditions change; hydraulics do not. The motor cutoff on both levers ensures no drive-versus-braking conflict, which at peak 1000W is a meaningful safety specification rather than a checkbox. Third-party testing on a private track confirmed the braking arrests momentum in a short distance even at elevated speed — the hydraulic system handles this weight class without drama or excessive lever travel.

Integrated Lighting

The 780-lumen headlight draws from the main battery and provides a wide flood angle adequate for moderate trail speeds at dusk. The 95 dB horn is integrated into the headlight housing — not immediately obvious on first inspection, but intuitive once located, and useful on mixed-use paths. The rear taillight runs independently. For technical trail riding in full darkness, a dedicated handlebar-mounted trail light remains the correct tool — the 780-lumen output is a solid road and dusk specification, not a night-trail one.

Lankeleisi RX800 Plus 2025 Review: User Interface and Controls

Display and Controls

The colour LCD display is centrally mounted and shows current speed, battery percentage, active PAS level, trip distance, and total odometer. Tactile buttons for PAS adjustment and light control are large enough to operate with gloves on, which matters for trail and cold-weather riding. Direct sunlight reduces readability — a limitation shared by all colour LCD panels at this brightness tier, not specific to the RX800 Plus, but worth knowing for consistently sunny environments. Pre-loading a route on a phone or GPS unit before setting off is a practical workaround. Access to the parameter settings requires pressing the + and – buttons simultaneously for three seconds — a menu layer not mentioned prominently in the included documentation, but useful for riders adjusting wheel size or speed display calibration.

Sensor Modes

The 2025 torque sensor replaces the cadence sensor of earlier units. A cadence sensor detects whether the pedals are turning and delivers a fixed assist level accordingly — the result is stepped, binary power delivery that feels mechanical on variable terrain. The torque sensor reads pedal force and scales motor output proportionally: push harder, receive more assist; ease off, and the motor backs down immediately. The RX800 Plus does not offer sensor mode switching as the Vakole EMT29 does, but for riders using this bike primarily off-road, the torque sensor alone is the correct choice for the platform.

Lankeleisi RX800 Plus 2025 Review: Accessories and Compatibility

Included Equipment

The RX800 Plus ships with rear rack, front and rear mudguards, anti-theft lock, pump, and a hex toolkit for final assembly. Assembly takes 30–45 minutes; the bike arrives largely pre-built, with handlebars, pedals, and front accessories requiring attachment. The carton weighs close to 50 kg — factor in a second person for unpacking, particularly on stairs or in a confined space. A throttle grip is also included in the box as an optional replacement for the standard right-hand grip, enabling full-throttle electric-only operation. On public roads in the EU, throttle use falls outside VAE regulations. On private land, it is one of the more compelling features of a 1000W full-suspension fat bike.

Compatible Upgrades

Universal e-bike accessories that fit cleanly include phone mounts, bar-end mirrors, and additional trail lighting for night riding. For maintenance: keep hydraulic brake fluid (mineral oil, compatible with the installed system), a spare derailleur cable, and a spare chain on hand for longer tour use. A rear derailleur guard — not included — is worth sourcing before the first off-road session. Riders evaluating lower-priced alternatives should read our Engwe L20 SE review for context on the trade-offs between a step-through folding fat bike and a full-suspension all-terrain platform at this weight and power class.

Lankeleisi RX800 Plus 2025 Review: Model Comparisons

RX800 Plus 2025 vs MG600 Plus

Key Differences: The RX800 Plus adds full rear suspension and a removable battery at approximately €200 more than the MG600 Plus. The MG600 Plus runs 26” wheels, which roll faster on smooth and mixed road-trail surfaces. The RX800 Plus’s 20” wheels are optimised for technical, lower-speed terrain where suspension compliance and fat-tire traction matter more than rolling efficiency. Riders who split time between road transfers and off-road sections will generally find the MG600 Plus’s wheel diameter more versatile; those who ride primarily technical tracks gain most from the RX800 Plus’s rear shock.

RX800 Plus 2025 vs MG600 Lite

Key Differences: These bikes serve different riders entirely. The MG600 Lite is EU VAE-compliant at 250W nominal, around 10 kg lighter, and well-suited to daily commuting and mixed-surface leisure riding. The RX800 Plus is a high-payload off-road platform that exceeds VAE power limits and requires checking local regulations before public road use. The €600 price gap reflects those differences accurately — neither is better in absolute terms.

Final Verdict

The Lankeleisi RX800 Plus 2025 is built for a specific type of rider, and it delivers well for them. A full-suspension fat-tire platform with 80 Nm of torque, a 960Wh Samsung 21700 battery, and an adjustable rear air shock is a genuinely difficult combination to find at €2,099. The torque sensor upgrade that defines this version is not cosmetic: it changes how the motor integrates with effort and makes extended riding noticeably less fatiguing than the cadence-sensor units that preceded it. The removable battery and comprehensive included accessories — rack, mudguards, throttle, pump, toolkit — make the practical ownership experience better than the raw spec list suggests.

Where it falls short is equally specific: 39–40 kg is genuinely heavy off the bike, and the 20” wheel diameter means slower rolling on flat tarmac than 26” or 27.5” alternatives. The 1000W motor places it outside standard EU VAE classification — understand this clearly before purchasing, not after. On private land, those same characteristics become advantages.
