TL;DR

Top pick: Inmotion V9 ($799.00) — a 16-inch wheel with 60mm air suspension and a 750Wh battery; eRideHero calls it "the best entry-level wheel you can buy" and measured 26.8 mph and 21.5 miles, Freshly Charged finds it a well-rounded wheel for commuters and beginners, and The Gadgeteer calls it a great step up from the E20. It weighs 50.7 lb in eRideHero's and The Gadgeteer's figures (Freshly Charged lists 48 lb). [src1, src3, src4]
Best budget / beginner: Inmotion E20 ($399.00) — one hub motor with two tires side by side, which helps you balance side to side; Freshly Charged says there is no better beginner wheel, New Atlas calls it a good place to start, and The Gadgeteer found it fairly easy to learn, though both The Gadgeteer and New Atlas took longer than the 3 minutes Inmotion promises. It tops out at 20 km/h (12.4 mph). [src5, src6, src7]
Best for agility: Nosfet Aero — a 54-lb suspension wheel; eRideHero's most agile pick, "the only suspension wheel that feels like a 'last mile' commuter", measured 34.5 mph and 28.2 miles, and Freshly Charged calls it a winner that blends lightweight portability with surprising power. Nosfet's own page had no store and pointed buyers to its retailers when we checked on 2026-10-15. [src1, src8, src19]
Best for street and trail: Nosfet Apex — suspension travel that adjusts without tools, from 55mm for pavement to 150mm for trails in eRideHero's figures; eRideHero's most versatile extreme wheel (59.4 mph, 49.2 miles, 85.5 lb), and Freshly Charged says the adjustable suspension makes it the right call over the Veteran Lynx for one wheel that handles trails and pavement, though its test unit's adjustment took serious effort at first. [src1, src9]
Best for top speed: Inmotion P6 — eRideHero clocked 75.2 mph, the fastest it has ridden an electric unicycle, and 58.7 miles of range; Freshly Charged calls it the fastest electric unicycle its team has tested and the current peak of the category, but at 112 lb it is not a beginner wheel. Inmotion's US store listed it at $4,999 when we checked on 2026-10-15. [src1, src10, src17]
Also consider, to carry it often: Inmotion V8S — eRideHero's most portable pick at 35.2 lb, with 21.5 mph and 20.6 miles in its test, but less stable above 18 mph. Inmotion's US store listed it at $599 (regular $1,099), available, when we checked on 2026-10-15. [src1, src14]
Also consider, for comfort: Inmotion V11Y — "the best suspension I've tested under $2000", says eRideHero, which measured 32.3 miles; at 66 lb it is the heaviest of eRideHero's intermediate picks. [src1]
Also consider, for range without suspension (sold out at KingSong, checked 2026-10-15): KingSong 16X — eRideHero's "range king of intermediate wheels", with 43.2 miles and 31.5 mph in its test from a 1,554Wh battery, but no suspension. KingSong's US store had it sold out when we checked on 2026-10-15. [src1, src2, src18]
Also consider, for steep hills: Inmotion V14 Pro — eRideHero's best hill climber, which it says climbs 35-degree inclines; 42.8 mph and 43.7 miles in its test, at 86 lb. Inmotion's US store listed it at $2,699 (regular $2,899), available, when we checked on 2026-10-15. [src1, src16]
Also consider, for off-road: KingSong S22 Pro — eRideHero's off-road pick, with the longest suspension travel in its high-performance group (130mm) and a 20-inch tire; 42.3 mph and 42.1 miles in its test, at 77 lb. [src1]
Also consider, for the longest range: Veteran Oryx — 89.3 miles in eRideHero's range test, "the best I've ever recorded (by far)", from a 4,700Wh battery, with 67.8 mph; it weighs 127 lb. [src1] We have no buy link for it: when we checked on 2026-10-15 we found no US product page from Leaperkim, its maker, to link to.

Summary

Our top pick is the Inmotion V9 because three outlets tested it and recommend it to beginners and commuters: eRideHero calls it "the best entry-level wheel you can buy" and measured 26.8 mph and 21.5 miles of real-world range, Freshly Charged rode it around Provo, Utah and calls it a well-rounded wheel for commuters and beginners, and The Gadgeteer's beginner reviewer calls it a great step up from the slower, easier E20. [src1, src3, src4] eRideHero says its 60mm air suspension is what sets it apart from entry wheels, most of which have none; the costs are 50.7 lb of weight and range that eRideHero says is not class-leading. [src1] Inmotion's US store states UL 2272 certification for the V9 and listed it at $799 (regular $1,299), available, when we checked on 2026-10-15. [src12]

For riders who have never balanced on one wheel, the pick is the Inmotion E20: its single hub motor drives two 14-inch tires side by side, which helps you balance side to side and lets you stand still at a light. [src6, src7] Freshly Charged says there is no better beginner wheel, and New Atlas says it got its reviewer riding where single-tire wheels had not and calls it a good place to start. [src6, src7] It is not instant: The Gadgeteer needed several sessions and several total hours, and New Atlas took longer than Inmotion's promised 3 minutes. [src5, src6] The testers disagree on its motor: The Gadgeteer found decent hill climbing for a beginner wheel and New Atlas climbed a fairly steep hill with ease, while Freshly Charged found it had a hard time making it up even small ramps or curbs. [src5, src6, src7] Inmotion's US store listed it at $399, available, when we checked on 2026-10-15; the E20 Lite it also sells, at $349, is a different model from the E20 these outlets reviewed. [src13] eRideHero's best learning wheel is the Begode A1, which is not on this card. [src1]

Three more wheels were tested by both eRideHero and Freshly Charged. The Nosfet Aero is eRideHero's most agile wheel and its favourite for stop-and-go city riding, and Freshly Charged calls it a winner; both say it is not the wheel for long-distance riding, and eRideHero blames its 1,110Wh battery. [src1, src8] The Nosfet Apex is eRideHero's most versatile extreme wheel, with suspension travel you set for pavement or trail without tools, and Freshly Charged recommends it over the Veteran Lynx for riders who want one wheel for both. [src1, src9] The Inmotion P6 is the fastest: eRideHero clocked 75.2 mph and Freshly Charged calls it the fastest electric unicycle its team has tested; Freshly Charged adds that it is not a beginner wheel. [src1, src10]

The other six wheels on this card each have one hands-on test that we found, eRideHero's, so they are alternatives rather than named picks: the Inmotion V8S (most portable), Inmotion V11Y (comfort), KingSong 16X (range), Inmotion V14 Pro (hill climbing), KingSong S22 Pro (off-road) and Veteran Oryx (longest range). [src1] Freshly Charged reviewed the original Inmotion V14 Adventure in 2024, but Inmotion says the V14 Pro raises top speed from 43.5 to 50 mph and torque from 230 to 276 N·m, so we count only eRideHero's test of the Pro; eRideHero's 42.8 mph is below the Pro's rated 50 mph. [src1, src11, src16]

The KingSong 16X was this card's value pick until now. We moved it to an alternative because eRideHero's is the only hands-on test of it we found, and a named pick here needs two; eRideHero still calls it "the range king of intermediate wheels". [src1, src2] Separately, KingSong's US store had the 16X sold out when we checked on 2026-10-15; the same store listed a 16X Pro, which we found no hands-on test of. [src18] There is no value pick on this card this time.

Battery figures are eRideHero's except the E20's, which is New Atlas's, as are the E20's rated range and speed limit; the P6's 112 lb is both eRideHero's and Freshly Charged's figure. [src1, src6, src10] Weights credited to another outlet are that outlet's: The Gadgeteer's for the V9 and E20, Freshly Charged's for the Aero and Apex. [src4, src5, src8, src9] The dated prices and stock for the Inmotion P6, V8S, V11Y and V14 Pro and the KingSong 16X come from the makers' US store pages; Nosfet's Aero and Apex pages had no store, so those rows carry no price. [src14, src15, src16, src17, src18, src19, src20] eRideHero's range tests use a 170 lb rider at typical cruising speeds, so compare range figures within its column rather than against the makers' claims. [src1]

Best for Each Use Case

Top Pick: Inmotion V9 — Check price

eRideHero lists a 750Wh battery, a 16 x 3-inch tire and a 1,000W motor (2,000W peak), and calls the V9 "the best entry-level wheel you can buy": it hit 26.8 mph with 21.5 miles of real-world range, handled steep 30-degree hills, and found the 60mm air suspension absorbs cracks, cobblestones and hard-packed trails. [src1] eRideHero's complaints are its 50.7-lb weight, range that is not class-leading and a higher price than simpler entry wheels, but it says you won't immediately outgrow it. [src1] Freshly Charged rode it on bike paths and rougher roads around Provo, Utah, calls its adjustable air suspension a game-changer in this price range, and lists as flaws no stock pads with slick pedals, a scratch-prone plastic shell, a display that is hard to read in sunlight, weak turn signals and an unstable kickstand. [src3] The Gadgeteer's reviewer, a beginner, found the suspension does a great job on minor bumps, often hit the parking button under the handle by accident while mounting, and wished it had padded foam on the sides. [src4] Inmotion's US store states UL 2272 certification and listed the V9 at $799 (regular $1,299), available, when we checked on 2026-10-15. [src12]

Best Budget / Beginner: Inmotion E20 — Check price

New Atlas describes a 450W (900W peak) hub motor driving two 14-inch pneumatic tires side by side, a 240Wh battery rated for up to 30 km (18.6 miles), speed modes of 7, 15 and 20 km/h, a 100 kg (220 lb) rider limit and a weight of 13.5 kg (30 lb). [src6] Freshly Charged says there is no better beginner wheel: you can step on and off without worrying about side-to-side balance and stand still at a stop, but the front light is dim, there is no kickstand, and the motor struggled with even small ramps or curbs. [src7] New Atlas climbed a fairly steep hill with ease but had to dismount on grass, found the two tires prefer straight lines and gentle arcs, and calls it a good place to start learning. [src6] The Gadgeteer needed several sessions and several total hours, found decent range and hill climbing for a beginner wheel, and after a few weeks was unsure about the two-tire design, which sometimes has to be tipped onto one tire to turn more than gently. [src5] Inmotion's US store states UL 2272 certification and listed the E20 at $399, available, when we checked on 2026-10-15. [src13]

Best for Agility: Nosfet Aero — Check price

Nosfet specifies a 126V 1,110Wh Samsung 50S battery, a 2,000W motor, 70mm of suspension travel, a 120 kg load limit and an IPX6 rating. [src19] eRideHero names it its most agile wheel: 34.5 mph and 28.2 miles in its test, the lightest of its high-performance picks at 54 lb, and its favourite for stop-and-go city riding; it warns that the battery makes anything beyond 20 miles tight, that it is not built for aggressive trail riding, and that the price is high for the specs. [src1] Freshly Charged found it nimble, strong on steep hills and with suspension that works for its weight class, but saw speed wobbles under hard braking at 30-35 mph, pedals that lose traction in mud, a frustrating app, a small display and a front light cable that unplugs easily. [src8] Nosfet's own page had no store and pointed buyers to its retailers when we checked on 2026-10-15. [src19]

Best for Street and Trail: Nosfet Apex — Check price

eRideHero calls the Apex the most versatile extreme wheel you can buy: its linkage suspension adjusts without tools from 55mm of travel for stability on pavement to 150mm for trail clearance, and at 85.5 lb it handles better than the 100-lb-plus wheels in that class. It measured 59.4 mph, the lowest of its extreme picks, and 49.2 miles from a 2,700Wh battery, and notes that the trolley handle costs extra and there is no native app. [src1, src20] Freshly Charged tested the air-shock version (the Apex also ships with a coil shock), rode it against the Veteran Lynx and recommends the Apex for riders who want one wheel for off-road trails and fast pavement; its test unit's suspension adjustment took serious effort at first, the companion app is Android-only, and a trim piece was peeling after 50 miles. [src9]

Best for Top Speed: Inmotion P6 — Check price

eRideHero clocked 75.2 mph, "the fastest I've ever done on an EUC", and 58.7 miles of range from a 235V, 4,200Wh battery, and says its cooling kept the controller from throttling during sustained high-speed runs; the trade-offs are 112 lb, first-generation platform risks and the price. [src1] Freshly Charged calls it the fastest electric unicycle its team has tested; its riders found 50 mph felt like cruising, praised the TPMS tire-pressure warning and the separate pedal-tilt settings for acceleration and braking, found the turn signals useless and the display about 3 mph optimistic, and say it is not a beginner wheel. [src10] Inmotion's US store listed the P6 at $4,999 when we checked on 2026-10-15. [src17]

Also Consider — To Carry It Often: Inmotion V8S — Check price

eRideHero's most portable pick weighs 35.2 lb, has a retractable handle and a narrow 16 x 2.125-inch tire, and went 21.5 mph and 20.6 miles in its test. eRideHero calls it strictly a smooth-road wheel that gets less stable above 18 mph, rates its IP54 sealing just adequate, and expects you to outgrow it within a year or two of regular riding. [src1] Inmotion's US store listed it at $599 (regular $1,099), available, when we checked on 2026-10-15. [src14]

Also Consider — For Comfort: Inmotion V11Y — Check price

eRideHero says the V11Y "has the best suspension I've tested under $2000": 3.3 inches of air suspension, an 18 x 3-inch tire, a 1,500Wh battery and IPX6/IPX7 weather sealing. It measured 32.3 miles; its results table lists 36.2 mph and its write-up 39.8 mph. At 66 lb it is the heaviest of eRideHero's intermediate picks, and eRideHero says its range suffers from the weight and drag. [src1] Inmotion's US store listed the V11Y at $1,399 (regular $2,399), available, when we checked on 2026-10-15. [src15]

Also Consider — For Range Without Suspension (Sold Out at KingSong, Checked 2026-10-15): KingSong 16X — Check price

eRideHero calls the 16X "the range king of intermediate wheels": 43.2 miles and 31.5 mph in its test from a 1,554Wh battery, a wide 16 x 3-inch tire and 53 lb, with a retractable trolley handle it still rates among the best. It has no suspension, so rough roads are harsh, and eRideHero finds it top-heavy above 25 mph. [src1, src2] KingSong's US store had it sold out at $1,459 (regular $1,749) when we checked on 2026-10-15; the same store listed a 16X Pro, which we found no hands-on test of. [src18]

Also Consider — For Steep Hills: Inmotion V14 Pro — Check price

eRideHero's best hill climber has a 4,000W motor (9,000W peak) that it says climbs 35-degree inclines, a 2,400Wh 134V battery, 85mm of progressive coil suspension and an IPX6 rating; it measured 42.8 mph and 43.7 miles riding aggressively, and at 86 lb finds it heavy for daily carrying. [src1] Inmotion's page for this model rates it at up to 74.5 miles of range, says the Pro raises top speed from 43.5 to 50 mph and torque from 230 to 276 N·m over the original V14, and its US store listed it at $2,699 (regular $2,899), available, when we checked on 2026-10-15. [src16] eRideHero's 42.8 mph is below the Pro's rated 50 mph. [src1, src16]

Also Consider — For Off-Road: KingSong S22 Pro — Check price

eRideHero's off-road pick has 130mm of suspension travel, the longest in its high-performance group, and a 20 x 3-inch tire that rolls over roots and rocks; it measured 42.3 mph and 42.1 miles and weighs 77 lb. eRideHero notes it is an older platform without an IPX6 rating, needs its suspension sliders kept clean and has less torque than the Inmotion V14 Pro on steep climbs. [src1]

Also Consider — For the Longest Range: Veteran Oryx

eRideHero got 89.3 miles from the Oryx, "the best I've ever recorded (by far)", from what it calls the largest battery of any production wheel (4,700Wh, 176.4V), and measured 67.8 mph. Its 22-inch tire and 90mm suspension suit long-distance and seated cruising, but at 127 lb it is the heaviest wheel in eRideHero's guide and feels sluggish in tight spaces. [src1] We have no buy link for the Oryx: when we checked on 2026-10-15 we found no US product page from Leaperkim, its maker, to link to.

Head-to-Head Comparisons

Inmotion E20 vs Inmotion V9

The Gadgeteer, whose reviewer also tested the E20, calls the V9 a great step up from the much slower but easier E20. [src4, src5] The E20 tops out at 20 km/h (12.4 mph) in its Sport mode; eRideHero measured the V9 at 26.8 mph. [src1, src6] The E20 weighs 29.8 lb and the V9 50.7 lb. [src4, src5]

Pick the Inmotion E20 if: you have never ridden and want help balancing side to side while you learn.
Pick the Inmotion V9 if: you want suspension and enough speed that you will not outgrow it quickly. [src1]

Inmotion V9 vs Inmotion V8S

In eRideHero's tests the V9 went 26.8 mph and 21.5 miles and the V8S 21.5 mph and 20.6 miles; the V9 has 60mm of air suspension and a 3-inch tire, while the V8S rides a narrow 2.125-inch tire and weighs 35.2 lb to the V9's 50.7 lb. [src1]

Pick the Inmotion V9 if: your roads are rough or you want to keep the wheel as your skills grow.
Pick the Inmotion V8S if: you carry the wheel up stairs or onto transit every day. [src1]

Nosfet Aero vs Inmotion V11Y

In eRideHero's tests the Aero went 34.5 mph and 28.2 miles at 54 lb, and the V11Y 32.3 miles at 66 lb; eRideHero says the V11Y has the best suspension it has tested under $2,000 and calls the Aero the most agile. [src1] Freshly Charged found the Aero's suspension effective for its weight class. [src8]

Pick the Nosfet Aero if: you want a light, nimble suspension wheel for city riding.
Pick the Inmotion V11Y if: you want the best suspension eRideHero has tested under $2,000 and rarely carry the wheel. [src1]

Nosfet Apex vs KingSong S22 Pro

In eRideHero's tests the Apex went 59.4 mph and 49.2 miles at 85.5 lb, with suspension that adjusts from 55mm to 150mm; the S22 Pro went 42.3 mph and 42.1 miles at 77 lb, with 130mm of travel. [src1]

Pick the Nosfet Apex if: you want one wheel for fast pavement and trails. [src9]
Pick the KingSong S22 Pro if: you ride mostly off-road and want the lighter of the two. [src1]

Inmotion P6 vs Veteran Oryx

In eRideHero's tests the P6 went 75.2 mph and 58.7 miles at 112 lb, and the Oryx 67.8 mph and 89.3 miles at 127 lb; eRideHero says the Oryx lacks the P6's explosive punch but is the more practical wheel for covering real distance. [src1]

Pick the Inmotion P6 if: top speed and acceleration are the point. [src10]
Pick the Veteran Oryx if: you want the most range and ride long distances, often seated. [src1]

Decision Logic

If you have never ridden an electric unicycle

→ Inmotion E20. Its two tires help you balance side to side, and Freshly Charged, New Atlas and The Gadgeteer all tested it as a learner's wheel; expect hours of practice rather than minutes. [src5, src6, src7]

If you want one wheel to learn on and keep

→ Inmotion V9. eRideHero calls it the best entry-level wheel you can buy, and Freshly Charged and The Gadgeteer recommend it to beginners and commuters. [src1, src3, src4]

If you carry the wheel up stairs or onto transit

→ Inmotion V8S (35.2 lb in eRideHero's figures), or the Inmotion E20 (29.8 lb in The Gadgeteer's) while you learn. Avoid the P6 (112 lb) and Oryx (127 lb). [src1, src5]

If your city streets are rough

→ Inmotion V11Y for the best suspension eRideHero has tested under $2,000, or the Nosfet Aero if you also want it light (54 lb). [src1, src8]

If you want the most range

→ Veteran Oryx (89.3 miles in eRideHero's test). For a lighter wheel, the KingSong 16X went 43.2 miles at 53 lb, but KingSong's US store had it sold out when we checked on 2026-10-15. [src1, src18]

If your route has steep hills

→ Inmotion V14 Pro, eRideHero's best hill climber, which it says climbs 35-degree inclines. [src1]

If you ride trails

→ KingSong S22 Pro for 130mm of suspension travel, or the Nosfet Apex if you also ride fast on pavement. [src1, src9]

If you are an experienced rider who wants top speed

→ Inmotion P6: 75.2 mph in eRideHero's test. Freshly Charged says it is not a beginner wheel and should not be a first purchase. [src1, src10]

Default recommendation

→ Inmotion V9, with the Inmotion E20 first if you have never ridden. [src1, src3, src4, src7]
