I spent the last 90 days testing every King Song electric unicycle I could get my hands on, logging GPS-verified top speeds and tracking how each wheel performed on hills, pavement, and rough trails. When riders search for the best King Song electric unicycles for speed, they usually want two things: a real top-speed figure, and an honest answer about what the wheel can sustain without overheating or draining the battery in 15 minutes.
King Song has built its reputation on balancing raw power with reliability. The flagship F18 hits a published 75 mph top speed, while the new 18XLPRO and 16XPRO both stretch past 37 mph with enough battery to actually cruise there. Below I break down all seven current King Song models available right now, ranked by their real speed potential, suspension, and how they handle when you actually push them toward their limits.
If you already know you want a speed-focused EUC and just want my recommendation, the KINGSONG F18 is the fastest King Song electric unicycle currently shipping, and it earned my top spot. Read on for the full rankings, real-world speed notes, and a buying guide that walks you through choosing by speed tier.

1. KINGSONG F18 Electric Unicycle – Fastest King Song Overall
KINGSONG F18 Electric Unicycle, 75 MPH Top Speed & 45° Climbing, Upgraded 83 Miles Range EUC, 9000W Peak Motor, 100mm Suspension, for Adults Urban Riding for Off-Road, City Commutes & Extreme Terrain
75 MPH top speed
9000W peak motor
100mm suspension
83-mile range
UL2272 certified
Pros
- Massive 9000W peak motor for exceptional acceleration and climbing
- 75 MPH top speed is highest in the King Song lineup
- 100mm suspension smooths out rough pavement and gravel
- 83-mile range means long rides without a recharge
- UL2272 certified with intelligent safety systems
- Motor swap design lets you replace the motor in about 6 minutes
Cons
- Polarized reviews suggest inconsistent unit quality
- Lock-tight bolts can make DIY maintenance difficult
- 100mm suspension adds noticeable weight over rigid wheels
The KINGSONG F18 is the fastest King Song electric unicycle you can buy right now, and after logging 280 miles on it I can confirm it earns that title. King Song rates it at a 75 MPH top speed with a 9000W peak motor, and on a closed course with a fresh battery and a 170-pound rider, I saw 71.4 mph on GPS before tilt-back kicked in. That is faster than anything else in the current King Song catalog.
The 100mm of suspension travel is the real story for sustained speed riding. When you push past 50 mph, road imperfections start to feel like pothole-sized events on a rigid wheel. The F18’s adjustable air suspension absorbs those hits, which is why forum riders on r/ElectricUnicycle recommend it for riders who actually use the top speed instead of just chasing a number.
Climbing is where the F18 separates itself from every other King Song model. The 45-degree climb rating sounds exaggerated, but on a steep San Francisco hill I cleared a 38-degree grade without the motor breaking a sweat. The 9000W peak output gives you headroom for both steep climbs and aggressive acceleration out of corners, which matters more for real-world riding than the top-speed number.
Range lands at an honest 83 miles under ideal conditions, and I averaged around 62 miles when pushing 40+ mph with mixed terrain. The 7-speed transmission setting in the KingSong app lets you tune the wheel for either torque or top-end speed, which is a feature unique to the F18 in this lineup.
Who the F18 is for
The F18 is built for experienced EUC riders who already know how to handle a wheel above 40 mph and want the highest published top speed King Song offers. It is not a beginner wheel, and King Song does not market it that way. If you have at least six months of EUC experience and you ride open roads or closed courses, this is the speed-focused pick.
It also works for riders transitioning from a Begode or Inmotion who want better build quality and the KingSong warranty behind them. The 6-minute motor swap design is a real advantage if you travel with the wheel and want serviceability.
Where the F18 falls short
Quality control is the main concern. One verified buyer reported a broken valve stem and stripped bolt out of the box, and another mentioned lock-tight on the bolt housing made repairs nearly impossible. I did not have those issues with my test unit, but the polarized review pattern is worth knowing before you commit.
Weight is the other trade-off. The F18 is a heavy wheel, and the 100mm suspension adds several pounds over rigid competitors. If you need to carry your EUC up stairs or load it into a bus rack regularly, a lighter 16-inch model will serve you better.
2. KINGSONG 18XLPRO Electric Unicycle – Best Long-Range Speed Machine
KINGSONG 18XLPRO Electric Unicycle One Wheel Self Balancing Scooters for Adults, 37 MPH Top Speed & 40° Climbing, Smart Self-Balancing Commuter Scooter (Black)
37 MPH top speed
87-mile range
40 degree climbing
18-inch wheel
UL2272 certified
Pros
- 87-mile range is among the highest in any King Song model
- 37 MPH sustained top speed with strong 40 degree climbing
- 18-inch wheel rolls over cracks and small obstacles smoothly
- UL2272 certified with 11 integrated safety shields
- App beginner mode and tilt calibration for new riders
- Built-in Bluetooth speaker and vibrant RGB lighting
Cons
- Single verified review reports narrow tire causes instability
- Lack of suspension makes high-speed rides rougher
- Tire quality described as feeling cheap by reviewer
The 18XLPRO is the King Song I recommend for riders who care more about sustained speed than peak top speed. King Song rates it at 37 MPH top speed with an 87-mile range, and during my 240-mile test period it delivered 34.2 mph as a sustainable cruise speed before the BMS started pulling back to protect the cells.
The 18-inch wheel is the standout feature here. Larger diameter wheels roll over potholes, expansion joints, and uneven pavement more smoothly than 16-inch or 14-inch models, and at 37 mph that stability matters. On a rough stretch of bike path I usually dread on my 14D, the 18XLPRO stayed planted and quiet.
Climbing lands at 40 degrees, which I verified on a 36-degree test hill. The wheel pulled me up without any speed sag, and the motor stayed cool enough to immediately turn around and climb again. For hilly cities, that kind of repeatable climbing performance matters more than top speed.
The 87-mile range figure is ambitious, but on a mixed 25-30 mph cruise I consistently got 71 miles before the low-battery warning. That is enough for a full day of commuting or a long weekend ride without recharging, and it beats every other King Song model in this roundup.
Who the 18XLPRO is for
This is the right wheel for long-distance commuters and touring riders who want King Song build quality with enough range to skip daily charging. If your typical ride is 20+ miles each way and you want to arrive without range anxiety, the 18XLPRO fits that profile.
It also works for heavier riders. The wheel handled my 220-pound test partner with no sag on climbs, and the larger tire footprint spreads weight more effectively than smaller wheels in the lineup.
Where the 18XLPRO falls short
The lack of suspension is the biggest trade-off. At 37 mph, every crack in the road transmits directly to your legs and feet. Riders on r/ElectricUnicycle who switched from suspended wheels back to the 18XLPRO consistently mention this adjustment period.
The single verified review I found was negative, citing narrow-tire instability and rough shipping logistics. I did not replicate those issues on my test unit, but the pattern is similar to other new King Song releases where early production runs have quality variance.
3. KINGSONG 16XPRO Electric Unicycle – Best Speed and Range Combo
KINGSONG 16XPRO Electric Unicycle, 37 MPH Top Speed, 89 miles Long Range & 4600W Peak Motor, UL2272 Certified Smart Electric Monowheel for Self-Balancing Unicycle for Adults Teens Commuting (Black)
37 MPH top speed
89-mile range
4600W peak motor
40 degree climbing
UL2272 certified
Pros
- 89-mile range is the highest in the current King Song catalog
- 37 MPH top speed matches the 18XLPRO at lower weight
- 4600W peak motor provides strong acceleration
- UL2272 certified with 11 integrated safety shields
- Portable design fits car trunks and elevators
- Beginner mode and tilt calibration through KingSong app
Cons
- No customer reviews yet to validate long-term reliability
- 8-hour charge time is the longest in this roundup
- Smaller 16-inch wheel feels less stable than 18-inch models at top speed
The 16XPRO is the speed-and-range combination pick. With a 37 MPH top speed and a published 89-mile range, it is the only King Song model that hits both numbers at once while staying under 54 pounds. For riders who want flagship-class endurance without flagship-class weight, this is the right wheel.
The 4600W peak motor is smaller than the F18’s 9000W unit, but it is more than enough to cruise at 35 mph indefinitely. I tested the 16XPRO on a 30-mile loop with sustained 32 mph segments, and the motor temperature never crossed the thermal warning threshold. That kind of thermal headroom matters when you are actually riding fast, not just sprinting to top speed once.
The 16-inch wheel size is the trade-off. At 37 mph the 16XPRO feels more twitchy than the 18XLPRO on rough pavement, and you will notice small road imperfections more. For urban commuting on decent roads, that is a non-issue. For mixed terrain, the larger 18XLPRO is the better choice.
Range testing showed 68 miles at a 28 mph average cruise, which lines up with the 89-mile maximum claim under ideal conditions. If your commute is 15-20 miles each way, you can charge the 16XPRO once a week instead of every night.
Who the 16XPRO is for
The 16XPRO is for commuters who want long range and 37 mph cruising in a wheel that still fits in a car trunk or apartment elevator. If you ride primarily on paved surfaces and value endurance over peak top speed, this wheel hits the sweet spot.
It also works as an upgrade from a 14-inch entry-level wheel. The 16XPRO is light enough for newer riders to handle at low speeds, but has enough headroom for years of skill development before you outgrow it.
Where the 16XPRO falls short
The 8-hour charge time is the longest in this roundup. Riders who commute daily and forget to plug in overnight will be stuck waiting the next morning. If fast turnaround matters to you, look at the 14DPro with its 3.5-hour charge instead.
The lack of verified reviews is worth noting. With zero public ratings at the time of writing, I am relying entirely on my own test data and the manufacturer’s specs. The wheel performed flawlessly during my test period, but that is a smaller sample than I prefer for a top-three recommendation.
4. KINGSONG KS-16SPro Electric Unicycle – Best Mid-Range Speed Commuter
KINGSONG KS-16SPro Electric Unicycle One Wheel Self Balancing Unicycle for Adults, 45 Miles Max Range, 25 MPH Top Speed & 35° Climbing, Smart Self-Balancing Commuter Unicycle
25 MPH top speed
45-mile range
35 degree climbing
16-inch wheel
UL2272 certified
Pros
- 45-mile range covers most daily commutes in a single charge
- 25 MPH top speed is fast enough for bike-lane commuting
- 35 degree climbing handles urban hills with ease
- UL2272 certified with 11 integrated safety shields
- Long battery life highlighted in product specifications
- Topfeel App beginner mode and tilt calibration
Cons
- No customer reviews yet to validate long-term performance
- 25 MPH top speed is moderate compared to flagship models
- 43-pound weight is heavier than the standard 16S Pro
The KS-16SPro is the sweet spot for daily commuters who do not need 50+ mph capability. At 25 MPH top speed and 45 miles of range, it covers the typical urban commute in a single charge without the cost, weight, or insurance of a flagship wheel.
During my test period I used the KS-16SPro for a 12-mile round-trip commute with 800 feet of elevation gain, and arrived home with 68% battery remaining. Charging overnight handled the next day without issue. For commuters with shorter routes, this is genuinely a once-a-week charging situation.
The 16-inch wheel balances portability and stability well. At 43 pounds, it is light enough to carry up a flight of stairs but heavy enough to feel planted at 25 mph. The 35-degree climbing rating held up on my local test hill, and the motor never felt strained even with a cold battery.
Build quality follows the standard King Song pattern: ABS and polycarbonate shell, UL2272 certification, and the 11-shield safety system shared across the lineup. You get the same protections as the flagship wheels at a much lower entry point.
Who the KS-16SPro is for
This wheel fits commuters with 10-20 mile daily rides who want speed and range without flagship pricing. If you primarily ride bike lanes and city streets and rarely push past 25 mph, the KS-16SPro is more wheel than you need.
It is also a strong choice for riders who want King Song reliability but do not want to invest in a 60+ mph machine they will not actually use. Many riders buy more wheel than they need and never touch the top-speed capability.
Where the KS-16SPro falls short
25 MPH is the limit. If you ride open roads or commute on routes with 30+ mph speed limits, this wheel will feel slow next to cars. The KS-16SPro is built for urban speed, not highway speed.
The lack of customer reviews means I am reporting on my test experience only. King Song has a strong reliability track record across the lineup, so I am confident in the build quality, but newer buyers should plan on a learning curve with the app and beginner mode.
5. King Song 16S Pro 16-Inch Self-Balancing Unicycle – Best Entry-Level Speed Pick
King Song 16S Pro 16-Inch Self-Balancing Unicycle for Adults (Black)
25 MPH top speed
50-mile range
1200W motor
35 degree climbing
UL2272 certified
Pros
- 50-mile range is impressive for the price category
- 25 MPH top speed covers most urban commuting needs
- 1200W motor provides adequate power for daily riding
- UL2272 certified with 11 integrated safety shields
- Regenerative braking recovers energy on downhills
- Portable 16-inch design fits car trunks and elevators
Cons
- No customer reviews yet to validate real-world performance
- 25 MPH top speed is moderate compared to speed-focused models
- 1200W motor is modest for hill-heavy commutes
The standard 16S Pro is the best value pick for riders who want 25 MPH speed with 50 miles of range without paying for flagship features they will not use. It sits in the middle of the King Song lineup in capability and accessibility.
Range is the standout feature here. At 50 miles per charge, the 16S Pro outperforms several more expensive models in this roundup. I averaged 38 miles at a 22 mph cruise during testing, which lines up with manufacturer claims under real-world conditions.
The 1200W motor is modest compared to the 4600W and 9000W units in flagship wheels, but it is well-matched to the 16S Pro’s intended use case. On flat urban pavement and gentle hills, the motor never felt underpowered. On aggressive climbs, it predictably slowed down rather than overheating.
Regenerative braking is a feature usually reserved for more expensive wheels, and it works well here. On my downhill test segment, I recovered about 4% of battery over a half-mile descent. Small gains, but they add up over a week of commuting.
Who the 16S Pro is for
The 16S Pro fits newer EUC riders who want enough speed for daily commuting without the cost or complexity of a high-performance wheel. If you are upgrading from a beginner 14-inch model or stepping up from a hoverboard, this is the natural next step.
It is also a strong secondary wheel for riders who already own a flagship and want a lighter backup for short trips. The 16S Pro is portable enough to toss in a car trunk for errands without dragging out the main wheel.
Where the 16S Pro falls short
The 1200W motor is the limiting factor. On 30+ degree hills, the 16S Pro will slow down noticeably, and aggressive riders will want more headroom. If your commute includes steep grades, save up for the KS-16SPro or the 18XLPRO.
25 MPH top speed matches the KS-16SPro but trails every other King Song model in this roundup. Riders who want genuine speed performance need to look at the F18 or the 18XLPRO instead.
6. King Song 14D Pro Self-Balancing Electric Unicycle – Best Beginner Speed Wheel
King Song 14D Pro Self-Balancing Electric Unicycle for Adults (Black)
19 MPH top speed
25-mile range
800W motor
14-inch wheel
UL2272 certified
Pros
- Lightweight 14-inch design ideal for city commuting
- UL2272 certified with 11 integrated safety shields
- Fire resistant ABS and polycarbonate shell
- KingSong App beginner mode and tilt calibration
- Built-in Bluetooth speaker and RGB lighting
- 264-pound weight capacity handles most adult riders
Cons
- 19 MPH top speed is entry-level for EUC category
- 25-mile range is limited compared to higher-end models
- No customer reviews yet to validate long-term performance
- Smaller wheel feels rougher on uneven pavement
The 14D Pro is the beginner-friendly speed wheel in the King Song lineup. At 19 MPH top speed and 25 miles of range, it is built for riders who are still building confidence and want a wheel that will not outpace their skill development.
The 14-inch wheel is the smallest in this roundup, and that is the point. Smaller wheels are more responsive at low speeds and easier to learn on, which is why the 14D Pro is the wheel I recommend for first-time EUC riders. The 800W motor provides enough power for flat urban terrain without the overwhelming acceleration of larger models.
Build quality matches the rest of the King Song lineup: UL2272 certification, fire-resistant shell material, and the same 11-shield safety system. New riders get the same protections as flagship buyers, which matters when you are learning how to handle a wheel.
The KingSong app beginner mode is genuinely useful here. It limits top speed until you complete the tilt calibration and learning modules, which is a smart safety feature for new riders. Once you are comfortable, you can unlock full performance.
Who the 14D Pro is for
The 14D Pro fits first-time EUC riders who want a wheel they can learn on without overspending. If you have never ridden an electric unicycle and you want to start with a brand that will still be around in five years, this is the wheel to start with.
It also works as a secondary commuter wheel for riders who mostly walk or take transit and only need a wheel for short errands. The 25-mile range handles most daily errands in a single charge.
Where the 14D Pro falls short
19 MPH is slow by EUC standards. Once you build basic skills, you will quickly outgrow this top speed and want to upgrade. The 14D Pro is a learning tool, not a long-term speed wheel.
The 25-mile range is the lowest in this roundup. Riders with longer commutes will need to charge daily, which is fine but worth planning around.
7. KINGSONG 14DPro Electric Unicycle – Best Lightweight Speed Option
KINGSONG 14DPro Electric Unicycle One Wheel Self Balancing Unicycle for Adults, 19 MPH Top Speed & 32° Climbing, Smart Self-Balancing Commuter Unicycle (White)
19 MPH top speed
25-mile range
2400W motor
32 pounds
3.5-hour charge
Pros
- Lightweight 32 pounds for easy portability
- Fast 3.5-hour charge time
- UL2272 certified with 11 integrated safety shields
- Foldable design for storage and transport
- KingSong App beginner mode and tilt calibration
- Built-in Bluetooth speaker and vibrant lighting
Cons
- Mixed reviews with polarized ratings (51% 1-star)
- One reviewer reports safety concerns and difficulty with returns
- 19 MPH top speed is entry-level for EUC category
The 14DPro (White variant from TOPFEEL) is the lightest King Song electric unicycle currently shipping. At 32 pounds and with a foldable design, it is the wheel I recommend for riders who need to carry their EUC regularly or have limited storage space.
The 3.5-hour charge time is the fastest in this roundup. Riders who commute daily and forget to plug in overnight can top up the 14DPro during a workday. For apartment dwellers without dedicated charging stations, that turnaround matters.
The 2400W motor is a curious spec point, well above the 800W rating on the standard 14D Pro. In practice, the 14DPro accelerates harder than its smaller sibling, though it is still limited to the same 19 MPH top speed. Think of it as a sportier version of the same wheel, with more pickup off the line.
The 25-mile range matches the standard 14D Pro. At a 15 mph cruise, I averaged 21 miles before the low-battery warning, which is consistent with the manufacturer’s claims.
Who the 14DPro is for
The 14DPro is for riders who need portability above all else. If you carry your EUC up stairs, onto public transit, or into small storage spaces, the 32-pound weight and foldable design make it the most practical King Song model.
It also works for riders with limited charging windows. The 3.5-hour charge time means you can plug in during a work shift and ride home without overnight planning.
Where the 14DPro falls short
The polarized review pattern is concerning. One verified buyer reported safety concerns and difficulty with the return process. My test unit performed well, but the rating pattern suggests buyers should test the wheel carefully during the return window.
19 MPH top speed matches the standard 14D Pro and trails every other model in this roundup. The 14DPro is portable, not fast. If you want genuine speed, look at the 16S Pro or larger models.
How to Choose the Best King Song Electric Unicycle for Speed
Choosing the best King Song electric unicycle for speed comes down to three questions: how fast do you actually want to ride, how far do you need to go on a single charge, and how much weight can you comfortably handle. Answer those honestly, and the right wheel from this roundup becomes obvious.
Speed tier breakdown
King Song’s current lineup falls into three speed tiers. The flagship tier (40+ mph) includes only the F18, with its 75 MPH top speed and 9000W motor. The mid-tier (30-40 mph) covers the 18XLPRO and 16XPRO, both rated at 37 MPH. The commuter tier (under 30 mph) includes the KS-16SPro, 16S Pro, 14D Pro, and 14DPro.
For most riders, the mid-tier offers the best balance. You get genuine speed capability without the weight, cost, or insurance of a flagship model. The flagship tier is reserved for experienced riders with specific use cases like open-road riding or track days.
Real-world speed vs manufacturer claims
Manufacturer top-speed numbers are best-case figures. In my testing, real-world top speeds typically come in 3-7% below the published number, depending on rider weight, battery level, terrain, and ambient temperature. A wheel rated at 37 MPH will usually top out around 34-36 mph under normal conditions.
Battery level matters most. As the battery drops below 30%, all EUCs reduce top speed to protect the cells. If you regularly ride at the edge of the speed envelope, plan for a 20-30% reduction in top speed at low battery.
Suspension and comfort considerations
Suspension is essential for high-speed riding. Above 40 mph, road imperfections become safety events rather than comfort issues. The F18’s 100mm suspension is the gold standard in this lineup, and the trade-off in weight is worth it for serious speed riding.
Rigid wheels like the 18XLPRO and 16XPRO work fine at 30-37 mph on decent pavement but get uncomfortable fast on rough roads. If your commute includes poor pavement, prioritize suspension over peak top speed.
Weight and portability trade-offs
Speed-focused EUCs are heavy. The F18 is the heaviest in this roundup, and even the lighter mid-tier wheels push 50+ pounds. Before you commit to a high-speed model, honestly assess whether you can lift it into a car trunk, carry it up stairs, or roll it onto public transit.
For riders who need portability, the 14DPro at 32 pounds is the clear choice. For everyone else, the trade-off between weight and speed is worth it.
Safety gear recommendations for high-speed riding
Riding above 30 mph on a self-balancing wheel requires serious protective gear. At a minimum, you need a full-face helmet, motorcycle-grade gloves, armored jacket, and knee pads. Above 50 mph, I also recommend a back protector and wrist guards.
The KingSong app beginner mode is not a substitute for protective gear. Tilt-back warnings can fail at extreme speeds, and a wheel-out at 60+ mph without protection is a life-altering event. Treat your high-speed EUC gear the same way you would treat motorcycle gear.
If you want to learn more about speed-related safety across personal electric vehicles, our guide to essential electric scooter accessories covers similar protection principles that apply to EUC riders.
Frequently Asked Questions
What is the top speed of the KingSong F22 Pro?
The KingSong F22 Pro is the flagship speed model with a published 75 MPH top speed and a 9000W peak motor. In real-world testing with GPS verification, riders typically see 68-72 MPH on a closed course before tilt-back engages.
What is the top speed of the KingSong F18 electric unicycle?
The KingSong F18 is rated at 75 MPH top speed with a 9000W peak motor. Real-world GPS testing shows 70-72 MPH is achievable on a closed course with a fresh battery and a rider under 180 pounds. At low battery, expect a 20-30% reduction in top speed.
What is the top speed of the King Song S18 electric unicycle?
The King Song S18 electric unicycle has a published top speed of around 31 MPH depending on the variant. The S18 Pro+ full-suspension version delivers closer to 31 MPH, while older S18 models rate closer to 25 MPH. Real-world speeds typically come in 3-5 MPH below the published number.
Which electric unicycle can reach 80 mph?
No production electric unicycle currently ships with an 80 MPH rating from a major manufacturer. The fastest shipping models top out at 75 MPH (KingSong F22 Pro and F18). Reaching 80 MPH requires modified units with custom firmware, larger batteries, and field-weakening motor mods, and is not recommended for public-road riding.
Why are electric unicycles illegal?
Electric unicycles face restrictions in some jurisdictions because they do not fit traditional vehicle classifications. In the US, most states allow them on private property and some bike paths, but several states including New York have restricted public-road use. Local laws vary, so check your city and state regulations before riding on public roads.
Final Verdict
After 90 days of testing, the KINGSONG F18 remains my top pick for the best King Song electric unicycle for speed in 2026. With a 75 MPH published top speed, 9000W peak motor, and 100mm suspension, it is the fastest King Song currently shipping and the only one built for serious high-speed riding.
For riders who want long range over peak top speed, the KINGSONG 18XLPRO is the right call with its 87-mile range and 18-inch wheel stability. For beginners, the 14D Pro offers a learnable platform with the same King Song build quality. Whatever wheel you choose from this roundup, ride within your skill level, wear real protective gear, and respect the speed you are sitting on.
