NOSFET Electric Unicycle Lineup (2026): Aero, Aeon, Xeno and Apex Compared

The NOSFET line-up at a glance

NOSFET electric unicycles: specs from NOSFET's model pages and manuals; dealer prices seen October 24, 2026

Model	Pack	Motor (rated / peak)	Speed figure NOSFET publishes	Tire	Suspension	Weight	Range NOSFET states	US dealer price
Aero	126V, 1,110 Wh	2,000 W / 8,000 W	34 mph closed-circuit max; 48 mph free spin	3.0-10	70 mm	54.7 lb (24.8 kg)	Not stated	$1,889 to $2,099
Aeon	151.2V, 1,300 Wh	2,200 W / 8,000 W	58 mph (93 km/h) free spin	3.0-12	90 mm	63.9 lb (29 kg)	47 miles (75 km), "est."	$2,299
Xeno	126V, 2,200 Wh	2,500 W rated; peak not stated	47 mph (75 km/h) max; 68 mph (110 km/h) free spin	80/90-14	90 mm	72.8 lb (33 kg)	68 miles (110 km), "est."	$2,999
Apex	151.2V, 2,700 Wh	3,200 W / 8,000 W	78 mph (125 km/h) free spin	2.75-14	55 to 150 mm, adjustable linkage	87.1 lb (39.5 kg)	Not stated	$3,299 to $3,699

Every pack uses Samsung 50S cells, per NOSFET. All four have a kickstand, a 20 W headlight (Next Gen Mobility's figure for the Xeno), IPX6 water resistance and a 120 kg (265 lb) maximum rider load. The Aero, Aeon and Xeno have a built-in trolley handle (a pull-out handle for rolling the wheel); on the Apex it is an add-on that eWheels sells separately. 126V is the full-charge voltage of 30 cells in series and 151.2V of 36; our battery voltage guide explains why higher voltage gives the motor more headroom at speed.

Where the numbers come from, and where they disagree

A free-spin speed is how fast the motor turns the wheel with no rider on it; you cannot ride at it. NOSFET publishes a riding figure for only two wheels: 34 mph for the Aero on a closed circuit with a full battery, and 47 mph "max speed" for the Xeno, which the Xeno page says is "based on standard weight and full charge conditions". For the Aeon and Apex it gives only free-spin speeds. The dealers fill the gap with their own figures, which we label as theirs below.

The sources disagree in a few places. The Apex weighs 39.5 kg (87.1 lb) in its manual and 38 kg (83.8 lb) on its product page, and Alien Rides lists 85.5 lb. NOSFET gives the Apex a 2.75-14 tire while eWheels' listing title says 80/90-14. The Xeno page's free spin of 110 km/h compares with 95 km/h at Next Gen Mobility, and the Xeno's 10,000 W peak power figure comes only from that dealer. Treat any number that decides your purchase as something to confirm with the dealer in writing.

Where to buy a NOSFET, and what it costs

NOSFET does not sell direct. Its site lists no store, gives sales@nosfet.com as the contact, and its manuals tell owners to go to their retailer first for support. None of the four is sold on Amazon; a search there on October 24, 2026 returned InMotion and King Song wheels only.

NOSFET wheels at three US dealers, October 24, 2026

Model	eWheels	Next Gen Mobility	Alien Rides
Aero	$1,999 (listing still reads "ETA: Mid October")	$1,889, in stock	$2,099, sold out
Aeon	$2,299, in stock	$2,299, in stock, seat and power pads included	Not listed
Xeno	$2,999, in stock	$2,999, in stock, seat and leg pads included	Not listed
Apex	$3,299 (was $3,799), back in stock	Not listed	$3,699, sold out

eWheels includes Beidou power pads (padded leg grips that attach to the shell) with all four. Buying from a specialist dealer means someone in the US handles setup questions, parts and warranty claims, which matters more for a brand with no US office. Our where to buy guide sets dealers, makers and Amazon side by side.

Which NOSFET fits which rider

Aero: the lightest and cheapest

The Aero puts a 126V, 1,110 Wh pack, 70 mm of adjustable coil suspension and 8,000 W of peak power into a 54.7 lb wheel on a 3.0-10 tire. Its short range is the trade: NOSFET publishes none, and the range calculator's profiles give 24 to 47 miles from the pack. It is the one to carry up stairs and onto a train. Our NOSFET Aero review reads its manual line by line.

Aeon: the Aero with more of everything

NOSFET calls the Aeon 16% larger than the Aero. It moves to the 151V class with a 1,300 Wh pack, a 2,200 W rated motor, 90 mm of suspension travel and a 3.0-12 tire, for 9 lb more weight and, at eWheels, $300 more. Each shock adjusts for rebound, preload and compression, and the manual's tip for heavier riders is to add compression if the suspension bottoms out often. The pedals take two sizes of overlay, so you can choose a smaller platform for cornering or a larger one for long rides.

NOSFET's 75 km (47 mile) range estimate comes with no test conditions; it works out to about 28 Wh per mile from the full pack. The EUC range calculator's three profiles give 28 to 55 miles. The stock 5 A charger supplies at most 756 W, so the bulk of a charge takes about 1.7 hours; NOSFET says 2.5 to 3 hours in all, and the charge port is rated to 10 A. For speed, NOSFET publishes only the 58 mph free spin; eWheels describes about 40 mph as the maximum speed and Next Gen Mobility 43 mph. Our NOSFET Aeon review reads its manual in full.

Xeno: the most range per pound

The Xeno is the line-up's long-range wheel: 2,200 Wh on an 80/90-14 tire (the 14-inch size Leaperkim uses on its Lynx and Sherman wheels), 90 mm of travel and a 2,500 W rated motor, at 72.8 lb. It is also the only NOSFET range figure with test conditions behind it. The Xeno page says an 80 kg (176 lb) rider averaging 35.8 km/h (22 mph) covered 103.4 km (64 miles), about 34 Wh per mile. That is a useful figure because it states the rider's weight and speed, and it makes a 50-mile round trip a reasonable plan.

Charging is slower than on the smaller wheels: NOSFET says 5 hours on the 5 A charger, and Next Gen Mobility gives 10 A as the official maximum. NOSFET says the Xeno's new springless trolley handle locks in place when pulled to the top and will not fall back when released. Because NOSFET has not posted a Xeno manual, its warranty terms and alarm settings are not published on NOSFET's site; ask the dealer for both before you buy.

Apex: the trail and jump wheel

The Apex is built around a linkage suspension with seven tool-free positions. On NOSFET's chart, travel runs from 55 mm with the pedals 225 mm (8.9 in) off the ground to 150 mm with the pedals at 313 mm (12.3 in): low and firm for speed, tall and soft for rough ground. eWheels' Apex listing notes that its latest shipment uses a DNM RCP 2S coil shock that allows six positions, with a 1,000 lb spring for riders under 210 lb and a 1,300 lb spring for heavier riders or frequent jumps.

The pack is 151.2V and 2,700 Wh, the motor 3,200 W rated, and the manual lists a dual-board controller with 36 MOSFETs (the power switches that feed the motor). eWheels says the controller and firmware, battery packs and motor follow Leaperkim's designs. Charging takes 4 hours at 5 A or 2 hours at 10 A per the manual. The stanchions (the sliding tubes of the suspension) need lubricating every 500 km (about 310 miles), and the manual gives suggested pressures by rider weight for an Apex fitted with an air shock. NOSFET gives only the 78 mph free spin; Alien Rides lists "55+ MPH". At 87 lb it is the heaviest of the four, and our off-road wheel guide covers other brands' trail wheels.

How NOSFET compares with wheels sold on Amazon

NOSFET against similar wheels: specs from the makers; prices seen October 24, 2026, and they change

Wheel	Pack	Motor (rated / peak)	Suspension	Weight	Wh per lb	Price seen
NOSFET Aeon	151.2V, 1,300 Wh	2,200 W / 8,000 W	90 mm	63.9 lb	20	$2,299 (dealers)
InMotion V12S	84V, 1,440 Wh	2,500 W / 6,000 W	90 mm	77 lb	19	$1,999 (Amazon)
NOSFET Xeno	126V, 2,200 Wh	2,500 W / not stated	90 mm	72.8 lb	30	$2,999 (dealers)
Leaperkim Patton-S	126V, 2,220 Wh	3,000 W / 7 kW	Up to 80 mm	Not stated	Not known	$2,899 (eWheels)
InMotion V14 Pro	134.4V, 2,400 Wh	4,000 W / 9,000 W	85 mm	86 lb	28	$2,699 (InMotion)
King Song F18	151.2V, 2,664 Wh	5,000 W / 11,000 W	100 mm	90 lb	30	$2,999 (Amazon)
NOSFET Apex	151.2V, 2,700 Wh	3,200 W / 8,000 W	55 to 150 mm	87.1 lb	31	$3,299 (eWheels)

The Xeno's case is weight. It carries about as much battery per pound as King Song's F18 and weighs 13 to 17 lb less than the V14 Pro and F18. What it gives up is motor: the F18 has twice the rated power for the same $2,999, and the V14 Pro has 4,000 W rated for $300 less, both with the maker's US support, and the F18 with an Amazon purchase and return. If you want the most power for the money, buy the F18; if you want the lightest wheel here that will cover a 50-mile round trip, the Xeno. Leaperkim's Patton-S has nearly the same pack for $100 less at eWheels, but neither dealer we read gives its weight.

The Aeon sits against InMotion's V12S: the V12S has a little more battery, sells on Amazon for $300 less, and is 13 lb heavier on an 84V pack. The Aeon's 151V pack and 8,000 W peak give it more headroom on climbs. Our brand comparison covers how each maker handles support and parts.

Tiltback, alarms and low battery

In the Aeon and Apex manuals, the rider sets the tiltback speed (the point where the pedals push back to slow you) anywhere from 10 to 200 km/h on the wheel's display, and the Aeon manual says the highest value turns tiltback off. It adds that the PWM alarm, which warns that the motor is near the limit of its power, always sounds at 86% and cannot be turned off; the Aero manual says the same. On both 151V wheels the low-battery alarm starts at 117V and the wheel tilts back at 113.4V; on the 126V Aero it is 91.5V and 88.5V.

Leave tiltback on and set it well below any speed in the tables above. Headroom shrinks as the battery drains, which is why the manuals prohibit hard acceleration below 60% battery. Our cutouts and tiltback guide explains why riding past the alarm is how riders get thrown.

Warranty, certification and safety reports

Warranty. The Aero and Aeon manuals list 24 months on the controller and motor, 18 months on the battery packs and 6 months on the charger. The Apex manual lists 24 months on the controller, 18 on the battery packs and 6 on the charger, with the shock under its own maker's terms; it gives no motor term. In every manual NOSFET covers parts only, not labor, shipping or other costs, and the warranty ends if anyone not authorized by NOSFET opens the wheel or if you keep riding after an alarm. Claims go through the dealer, whose own terms can differ; our warranty comparison sets these against the other makers.

UL 2272. None of NOSFET's model pages, its three manuals or the dealer listings we read mentions UL 2272 certification. New York City's Local Law 39 of 2023 requires it for devices sold, leased or rented in the city. If it matters to you, ask the dealer for the certificate before you buy; our UL 2272 guide explains what it covers.

A UK safety report on the Aero. On October 10, 2025, the UK's Office for Product Safety and Standards published a product safety report on a NOSFET Aero (PSD 2510-0012) with a risk level of "Serious" and a risk type of fire. It says the unicycle, battery and charger had not been assessed under UK conformity procedures, had no valid technical documentation and lacked labelling, marking and instructions, so that "it may be possible for the charger and/or battery to overheat". The import was rejected at the UK border. The report does not describe a fire or a test result; its finding is that conformity could not be shown. The US Consumer Product Safety Commission's recall database listed no NOSFET recall when we searched it on October 24, 2026.

Who should skip NOSFET

Skip NOSFET for a first wheel: the lightest model weighs 55 lb and has 8,000 W of peak power, and the Aeon and Apex manuals bar riders under 16 and over 60. Start with our beginner picks. Skip it too if you want to buy from the maker or on Amazon, if you need a UL 2272 certificate in hand, or if you want a full maker spec sheet in text rather than images. NOSFET's manuals call a full-face helmet, elbow and knee protection, a chest guard and wrist guards mandatory; our protective gear guide covers the standards to look for.
