KuKirin G4 is the high-output single-motor model for riders who have moved beyond ordinary commuter priorities. Its 2000W rear motor, 60V 20Ah battery, up-to-75 km listed range and 70 km/h listed maximum speed create a clear mission: preserve strong performance and route reserve on a large, stability-focused platform.
Its value is the way those headline numbers are supported by the rest of the machine. Eleven-inch ultra-wide pneumatic tires, four-arm suspension, front and rear disc brakes, a touch-control display and a 37 ± 1 kg chassis all serve riders who prioritize capability over portability. This review explains who benefits from that system and who should choose a lighter KuKirin.

The Product Mission: Keep Performance Available When One Motor Becomes the Bottleneck
G4 starts from a different brief than the G2 family: maximize sustained output and route reserve in a single rear-drive platform. The 2000W motor, 60V electrical system and 1200Wh-class battery are coordinated around that mission.
Keeping one driven axle makes the architecture easier to understand than a dual-motor layout, while the large rear motor still supplies the operating margin experienced riders want for open routes, gradients and heavier loads. The 11-inch ultra-wide tires, four-arm suspension and large chassis exist to make that output controllable rather than merely impressive on a specification sheet.
Product missionG4 is KuKirin's high-output single-motor choice: a large 60V platform for experienced riders who value speed reserve, long listed range and chassis stability more than low carry weight.
The design follows that purpose. A listed 37 ± 1 kg frame resists frequent stair carrying; 11-inch ultra-wide pneumatic tires add contact area and compliance; four-arm suspension manages larger surface changes; and the folding structure reduces storage height without pretending the scooter is lightweight.
Who Gets the Most Value From the KuKirin G4?
Riders with repeated gradients
High-output single motors are valuable when climbing is part of the normal route rather than an occasional obstacle. The official listing rates climbing capability at up to 30 degrees, though actual performance depends on rider weight, surface grip, battery state and conditions.
Heavier-duty commuters with ground-level storage
The 120 kg listed load limit and stronger drive layout suit riders carrying more total mass, provided the scooter can roll into a garage, ground-floor storage area or suitable vehicle. A 37 kg machine is a poor match for frequent stair carrying.
Experienced riders who can use selectable performance responsibly
The listed speed levels of 20, 40 and 70 km/h allow the platform to serve different riding contexts. That flexibility has value only where the rider has the skill, legal setting and protective equipment appropriate to the selected mode.
Buyers replacing a single-motor scooter for a specific reason
The cleanest case for G4 is evidence from the current route: sustained speed loss on hills, inadequate acceleration under load or recurring terrain that asks too much from one driven wheel.
Choose another model if compact storage, low weight or easy carrying matters more than high-output single-motor response. G2 Max is the more rational alternative when listed 75 km range matters but a single 1000W motor is enough. G2 is the lower-output value baseline. G4 suits buyers who want the 2000W high-speed platform rather than the G2 family’s high-output single-motor interpretation.
KuKirin G4 Specifications at a Glance
These specifications explain the hierarchy. The motors create the performance ceiling; voltage supports power delivery; capacity supports time away from the charger; chassis mass and tire volume keep that output attached to a usable platform. Listed range, speed, climbing angle and braking distance are not promises for every rider or surface.
Why the 2000W Rear Motor Defines the G4
Adding motor output is useful only when it changes what happens under resistance. A hill, heavier combined load, loose surface or repeated acceleration increases the demand at the tire. With one driven wheel, all propulsion must pass through one motor and one contact patch. G4 distributes that work across the front and rear.
The functional effect is stronger response when a single motor would be approaching its practical limit. For the buyer, that means less need to plan around the weakest part of a route. The real use case is not a one-time top-speed run; it is a commute with the same climb every day, a heavier rider who needs operating margin, or private-land riding where repeated acceleration is part of the experience.
Design insightThe 2000W motor earns its size when the route repeatedly demands stronger acceleration, climbing reserve or speed stability. On short, flat urban trips, a lighter lower-output model is usually the more efficient choice.
The 60V architecture supports the two-motor system with a higher electrical baseline than the 48V G2 Max. That does not make voltage a benefit by itself. Its value appears when the controller, battery and motors work together to deliver the response the platform was built for.
The 60V 20Ah Battery Supports Output and Route Reserve
KuKirin lists a 60V 20Ah lithium-ion battery and up to 75 km of range. The specification exists for two jobs. First, it supplies a higher-voltage high-output single-motor platform. Second, it gives the scooter enough stored energy to remain useful beyond short urban hops.
Those jobs compete. Using the 2000W motor hard, riding near the upper speed modes, climbing frequently or carrying more mass consumes energy faster. A buyer planning a long route should treat 75 km as a controlled-condition comparison figure and build a reserve for wind, temperature, stop-start traffic, tire pressure and battery ageing.
The listed 10–11 hour charging time also changes ownership. This is better suited to overnight charging than a quick turnaround between two demanding sessions. The design favors capacity and performance continuity over rapid top-ups.
The Chassis Converts Motor Output Into Usable Contact
Two motors cannot create useful traction if the tires skip across broken ground. The 11-inch ultra-wide pneumatic off-road tires provide air volume and tread compliance, helping the contact patches follow surface changes. Suspension then manages larger movements that the tires cannot absorb alone.
The buyer benefit is control margin on cracked pavement, compacted tracks and transitions where a narrow solid tire would transmit more impact. The large chassis and 11-inch tires broaden the surfaces the scooter can approach, though it does not turn the scooter into a motorcycle or remove the need to slow for obstacles.
The aluminum-alloy frame and 37 kg mass give the platform a substantial base for the motor and battery system. That can support a planted feel, but the cost appears immediately when the scooter must cross stairs, narrow landings or a small vehicle opening.
Control Hardware Matters More as Performance Rises
The official listing provides three speed levels—20, 40 and 70 km/h—with a default speed of 25 km/h. Modes make the available output easier to match to the setting. Lower response is useful around shared spaces and tight maneuvers; higher settings belong only where law, surface, visibility and rider skill allow them.
The headlight is mounted low on the front assembly, illuminating the path from near the chassis. Its practical value is early surface recognition, while the handlebar layout keeps display information and braking controls inside the rider’s immediate operating zone.
KuKirin lists a braking range of 6–8 m, but stopping distance changes with speed, load, tire grip, road condition and rider input. Treat the figure as supplied product data, not a universal outcome. The faster the selected mode, the more space and anticipation matter.
Folding Reduces Storage Length, Not Carrying Effort
The folded dimensions—1336 × 660 × 550 mm—show what the hinge is designed to solve. It lowers the stem and makes the scooter easier to place in a garage, storage room or sufficiently large vehicle. It does not erase the 37 kg listed mass.
That distinction prevents a common buying mistake. A folding commuter scooter is often expected to be carried onto public transport or upstairs. G4 is better understood as a performance scooter that folds for storage. Buyers should measure doorways, vehicle openings and storage space, then account for how the full weight will be moved without riding.
KuKirin G4 vs G2, G2 Max, G2 Master and M4 Max

KuKirin G2 2026
800W · Up to 55 km · 45 km/hMission: provide the balanced value baseline for everyday routes without the weight, speed and storage demands of the G4 platform.
Best for: urban riders who need useful suspension, range and motor reserve but have no recurring reason to move to a 2000W scooter.

KuKirin G2 Max
1000W · Up to 70 km · 55 km/hMission: extend single-motor range and road capability while remaining below the G4’s 60V, 2000W performance tier.
Best for: riders who value long listed range and a removable seat more than maximum output or 11-inch tires.

KuKirin G2 Master
1000W × 2 · Up to 70 km · 60 km/hMission: use two driven wheels to improve acceleration and climbing response instead of concentrating 2000W at the rear wheel.
Best for: experienced riders whose regular gradients or heavier loads make dual-motor traction more valuable than the G4’s higher listed speed.

KuKirin M4 Max
800W · Up to 64 km · 45 km/hMission: offer a different 800W chassis and range proposition for buyers who do not need the G4’s high-output single-motor role.
Best for: shoppers comparing utility and platform layout before paying for a performance upgrade.
Choose according to the hardest repeated part of the route. G2 is the balanced value baseline. G2 Max adds single-motor range and output. G2 Master prioritizes dual-motor traction and response. G4 targets the higher-speed 60V single-motor role, while M4 Max offers another utility-focused 800W route. A larger specification is worthwhile only when its design mission solves a real ownership problem.

What to Check Before Buying
Check local rules first. A merchant-listed maximum of 70 km/h does not establish where the scooter may legally be ridden or at what speed. Confirm vehicle classification, permitted spaces, speed limits, registration or insurance requirements and protective-equipment rules for the intended location.
Measure the ownership route next. At 37 ± 1 kg, G4 should have a realistic path into storage. IPX4 is limited splash resistance, not permission for deep water, pressure washing or careless wet-weather storage.
Finally, decide whether the 2000W motor have a repeated job. If the route is moderate and flat, G2 Max can preserve the same listed 75 km comparison while avoiding the complexity of selecting G4 solely for unused output.
Is the KuKirin G4 Worth Buying?
Yes—when the buyer can name the route condition that requires two driven wheels. The value chain is coherent: one 2000W rear motor distribute propulsion, the 60V 20Ah battery supports the drive system, pneumatic off-road tires and suspension keep the chassis connected to imperfect ground, and the wide deck gives the rider room to manage acceleration and braking.
No—when the upgrade is driven only by a larger specification. Choose G2 Max for a simpler 1000W, 70 km listed-range proposition; G2 for lower-output urban balance; or a lighter commuter scooter when carrying and compact storage dominate the week.

Frequently Asked Questions
Who is the KuKirin G4 best for?
It is best for experienced riders whose repeated routes include gradients, heavier loads or acceleration demands that expose the limits of a single-motor scooter. Its 37 kg listed weight makes it less suitable for frequent stair carrying.
Does the KuKirin G4 have the 2000W motor?
Yes. The official listing specifies one 2000W brushless rear motor on a 60V platform. Its value is stronger rear-wheel response and operating margin under load, not simply a larger headline number.
What range does the KuKirin G4 list?
The official product page lists up to 75 km. That is a comparison figure, not a guaranteed distance. High-output single-motor use, speed, rider load, gradients, temperature, tire pressure and stop-start riding affect consumption.
What is the listed maximum speed?
The official listing states up to 70 km/h and a default speed of 25 km/h. Buyers must follow the legal limits and permitted-use rules that apply to their location.
What battery does the G4 use?
The official listing specifies a 60V 20Ah lithium-ion battery and a listed charging time of about 10 to 11 hours. The higher-voltage platform supports the high-output single-motor system, while the capacity provides the energy reserve needed for longer routes.
Is the KuKirin G4 easy to carry?
Not for most buyers. Its listed weight is 37 ± 1 kg. The folding mechanism helps it enter storage or a suitable vehicle, but folding does not turn it into a light commuter scooter.
Should I buy the G4 or G2 Max?
Choose G4 when high-output single-motor response is the reason for upgrading. Choose G2 Max when a 70 km listed range and a simpler single-motor 1000W platform better match the route.
