Electric Unicycle Nosfet Apex (3200 W / 2700 Wh)

The NOSFET Apex is NOSFET's flagship electric unicycle, designed by a team of engineers from KingSong and Leaperkim, with designer Jack Hsu. It falls within the most demanding segment of high-performance 20-inch EUCs, in direct response to the needs of experienced riders who refuse to choose between a fast city wheel and a machine capable of taking on the most technical trails. With its 2,700 Wh at 151.2 V, its 3,200 W motor, and its progressive linkage suspension adjustable across 7 positions without tools, the NOSFET Apex embodies a simple philosophy: a single wheel to do everything, without compromise on durability or performance. A machine built for riders who want to push their limits, not manage them.

Overview

The NOSFET Apex is a 20-inch electric unicycle positioned in the premium race and offroad segment. It constitutes the high-end model of the NOSFET range, above the Aero and the Aeon in terms of raw power, battery capacity, and terrain versatility.

With its 38.8 kg and its dimensions of 73.5 x 54.5 x 20.7 cm, the NOSFET Apex is not a portability machine — it is a performance machine. Its 3,200 W nominal motor coupled with a 2,700 Wh battery at 151.2 V gives it an announced range of 100 km and a maximum speed of 90 km/h, for a real range of about 80 km in mixed riding. The DNM progressive linkage suspension, with a travel adjustable from 55 to 150 mm across 7 positions without tools, constitutes the differentiating core of the machine: it adapts as well to daily urban use with low suspension as to technical trails with high travel. The choice between a spring shock absorber (750, 1,000 or 1,300 lbs depending on the rider's build) or air (DNM TRU8RC) is made at the time of ordering.

Who is it for?

The NOSFET Apex is aimed above all at the experienced rider looking for a single machine for all uses. The adjustability of the suspension across 7 positions, the pedal height adjustable from 225 to 313 mm, and the two available tire variants make it possible to switch from an urban setting to an offroad configuration without tooling. Testers are unanimous: once the wheel is configured to its build, it responds like a dedicated machine, whatever the terrain.

It will also suit the race and offroad rider who frequents jump parks, MTB trails, or dirt tracks. The progressive linkage suspension with 150 mm of maximum travel takes on landings that few other EUCs can absorb without damage. The robustness of construction — omnipresent metal, plastics nearly absent, aviation-grade bumpers — makes it possible to push the machine without fear of damaging it.

On the other hand, the NOSFET Apex is not suited to beginners: the suspension setting can be intimidating, and 38.8 kg make the machine difficult to handle off the saddle. Nor is it intended for riders who prioritize portability on a daily basis.

What sets it apart

The NOSFET Apex stands out first of all for the amplitude and modularity of its suspension. A travel adjustable from 55 to 150 mm across 7 positions without tools is a record in the 20-inch class: it makes it possible to adapt the machine to radically different uses without complex mechanical modification. The choice between a spring shock absorber in three stiffnesses (750, 1,000, 1,300 lbs depending on build) or air adds a layer of customization rare at this level.

Second differentiator: the pedal height adjustable from 225 to 313 mm across 7 positions, aligned with the 7 suspension positions. This synchronization makes it possible to simultaneously adjust the ground clearance and the riding position, a design detail that concretely changes the riding dynamics in the city as well as on trails.

Finally, the dual-board controller with 36 MOSFETs and 840 A maximum current, developed on the proven Leaperkim architecture, guarantees a constant motor response even at a low battery level — a point that long-distance riders will appreciate directly.

What we like / Points of vigilance

• The DNM progressive linkage suspension: 150 mm of maximum travel, fully adjustable without tools, with a feel unanimously praised by testers as the best available on an EUC to date
• The robustness of construction: omnipresent metal, high-resistance bumpers, absence of fragile plastics — a machine that testers describe as capable of taking repeated falls without visible marks
• The real versatility of the setting: pedal height and suspension synchronized across 7 positions, allowing a clear transition between urban use and offroad without disassembly
• The manufacturer's warranty: 18 months on the battery, 24 months on the motor and the controller
• The weight of 38.8 kg: the NOSFET Apex is not a wheel you carry — it is rolled. The absence of a standard trolley handle confirms it
• The calibration of the pedals can require time and patience before obtaining a stable and satisfactory setting, according to the feedback of several testers
• The comfort accessories (power pads, seat) are not included in the standard box and represent an additional cost to anticipate

FAQ

• Is the NOSFET Apex suitable for daily use in the city? Yes, provided you accept its 38.8 kg and the absence of a standard trolley handle. By setting the suspension to the low positions and the pedal height to 225 mm, the NOSFET Apex configures itself for smooth urban use. Its real range of about 80 km and its fast charge in 2 h with a dual charger make it compatible with long daily trips.
• Which suspension version to choose at ordering for the NOSFET Apex? The technical sheet indicates three spring stiffnesses available: 750 lbs for riders under 95 kg, 1,000 lbs up to 120 kg, and 1,300 lbs for riders over 95 kg who regularly practice jumps. An air shock absorber version (DNM TRU8RC) is also available, offering even finer adjustability. The choice is made at ordering according to build and main use.
• Is the NOSFET Apex reliable for intensive offroad use? The feedback of testers confirms a high durability in intensive offroad conditions: the machine was subjected to jumps, failed landings, and technical trails with no mechanical failure reported. The IPX6 certification, the almost entirely metal construction, and the 840 A controller are consistent with this use. The only points of vigilance noted concern the calibration of the pedals and the initial setting of the suspension.
