KuKirin G2 Master vs G3 Pro vs G4: Which Performance Scooter Should You Buy?

Performance is not one thing

The KuKirin G2 Master, G3 Pro and G4 can all sit on a performance shortlist, but they deliver that performance in different ways. G2 Master balances dual-motor output with a 33.1 kg chassis. G3 Pro goes further with dual 1200W motors, oil brakes and a removable 23.4Ah battery. G4 uses one 2000W motor, a 60V system and wide 11-inch tyres.

The question is not simply “which is fastest?” It is which combination of traction, range, braking, tyre format, charging and weight solves the route you actually have.

The short recommendation

• Choose G2 Master for dual-motor traction and strong hill capability in the lightest chassis of these three.
• Choose G3 Pro when removable-battery convenience, the largest rated range, oil brakes and maximum dual-motor reserve justify the highest weight and price tier.
• Choose G4 when you want the large 11-inch tyre format, a 60V platform and strong single-motor character without needing dual-motor traction.

Current specifications compared

G2 Master: the performance sweet spot

G2 Master is the easiest of these three to recommend to someone who clearly needs dual motors but does not want the largest chassis in the range. Its two 1000W rated motors provide front-and-rear drive, while the 52V 20.8Ah battery supports an up to 70 km manufacturer-rated range.

The advantage is not only acceleration. Dual motors can provide useful traction and sustained load support on steep or loose private-land surfaces. The listed hill ability reaches up to 28°. The hydraulic suspension architecture also separates it from simpler spring setups.

At 33.1 ± 0.5 kg, it is still heavy. “Lightest here” does not mean portable. Measure storage and vehicle loading before treating the folding mechanism as proof that carrying will be easy.

G3 Pro: maximum reserve and ownership flexibility

G3 Pro is the most complete high-output package in this comparison. Dual 1200W rated motors, a 52V 23.4Ah battery, up to 80 km rated range, oil brakes and an up to 35° dual-motor hill rating put it at the top of the current scooter range for sustained capability.

Its removable battery is a practical difference, not a decorative feature. Riders who store the scooter away from a suitable charging point can remove the battery for charging and secure storage, following the exact manual instructions. Replacement and service can also be more manageable when every compatibility detail matches.

The cost is mass. At 39.6 kg, G3 Pro is approximately 6.5 kg heavier than G2 Master. That gap can decide the purchase for anyone with stairs, a high car boot or tight storage. Its charging time is listed as approximately 4–11 hours depending on charger setup, so confirm the supplied configuration rather than assuming the shortest figure.

G4: big-tyre, high-voltage single-motor character

G4 takes a different route. It uses one 2000W rated motor, a 60V 20Ah battery and 11-inch wide tubeless off-road tyres. Its maximum speed is listed at 70 km/h, its rated range up to 75 km and hill ability up to 30°.

Why choose a strong single motor over two motors? The delivery can feel simpler, there is no front-drive system to manage, and the large tyre format shapes stability and obstacle response. The 60V electrical platform also distinguishes G4 from the 52V dual-motor pair.

Why not choose it? A single driven wheel does not provide the same traction pattern as dual motors on loose or steep surfaces. The 11-inch chassis is also physically large, and the 10–11 hour listed charging time is the longest of the three.

Which climbs best?

The rated order is G3 Pro up to 35° in dual-motor mode, G4 up to 30° and G2 Master up to 28°. Maximum hill figures are highly sensitive to rider load, battery state, surface grip, temperature, run-up and the length of the climb. They should be treated as comparison signals, not a promise that every slope below the number will be easy.

If traction on loose private-land surfaces is central, dual motors offer a structural advantage. If your route is mostly firm and you value the G4 tyre format and 60V single-motor design, its different approach can be the better fit.

Which gives the best range?

G3 Pro leads on the spec sheet at up to 80 km, followed by G4 at up to 75 km and G2 Master at up to 70 km. At performance speeds, real range can fall far below the headline. Dual-motor use, repeated acceleration, cold weather, hills and higher load all increase consumption.

Buy range headroom. Do not plan a route that only works if the manufacturer maximum appears every day.

Which is easiest to own?

G2 Master wins on listed weight and charge time. G3 Pro wins on removable-battery flexibility and maximum capability but demands the most space and handling effort. G4 sits between them in weight, uses the largest tyres and has the longest listed charge time.

All three require serious storage, regular tyre and brake inspection, and appropriate protective equipment. A high-output scooter should not be bought before deciding where it will live, where it will charge and who will service safety-critical components.

Choose by scenario

• Steep private-land route, dual-motor traction, balanced mass: G2 Master.
• Maximum range headroom, strongest hill rating, removable battery: G3 Pro.
• Wide 11-inch tyres, 60V system, high-output single-motor feel: G4.
• Regular stairs: reconsider all three and compare lighter models.
• Mostly flat urban commuting: you may be paying in weight and charging time for performance you rarely use.

The responsibility that comes with the performance

These manufacturer maximum speeds exceed common public-road limits in many European jurisdictions. A lower riding mode does not always change the legal vehicle category. Check the exact product, approval documents, registration, insurance, equipment and permitted riding areas before purchase or use.

All three carry IP54 ratings. That is limited resistance, not waterproofing. Avoid immersion, deep water, pressure washing and charging when wet. Inspect tyres, brakes, folding and steering components before every ride.
