KuKirin G2 Pro vs G4 vs G2 Master is a choice between three very different ways to spend your money. The G2 Pro is the light model with a seat, the G4 has the biggest battery and the biggest wheels, and the G2 Master has two motors. Here we compare them side by side using the figures from the manufacturer’s manuals – and say plainly what you pay in weight and charging time.
Short answer: G2 Pro, G4 or G2 Master?
Choose the G2 Pro if you want to sit and sometimes lift the scooter – it weighs 26.7 kg. Choose the G4 for long rides on tarmac, with the biggest battery and 11-inch tyres. Choose the G2 Master for gravel, where two motors give grip. All three are rated for 20-degree climbs.
KuKirin G2 Pro vs G4 vs G2 Master in numbers
| Model | Motor | Battery | Weight | Tyres | Seat | Charging |
|---|---|---|---|---|---|---|
| G2 Pro | 600 W | 720 Wh | 26.7 kg | 9 inch, off-road | Yes | 7–8 h |
| G4 | 2,000 W | 1,200 Wh | 37 kg | 11 inch, pneumatic | No | 10–12 h |
| G2 Master | 2 × 1,000 W | 1,082 Wh | 41.5 kg | 10 inch, off-road | No | 10–11 h |
Motor power is nominal, and weight and charging time come from the manufacturer’s manuals. All three have front and rear suspension, front and rear disc brakes, indicators and a 120 kg maximum load, and none of them has a removable battery. Battery capacity in watt-hours is the fairest way to compare range.
G2 Pro – the lightest and the only one with a seat
The G2 Pro is the one to choose if you want to switch between standing and sitting. The seat comes in the box, and at 26.7 kg it is ten kilos lighter than the G4. The 600 W motor is the weakest of the three, but it is enough for city traffic and moderate hills. You’ll find more models you can sit on among our electric scooters with seats.
Two things to know. The tyres are only 9 inches, so cobbles and roots are felt more than on the bigger wheels. And when Forococheselectricos tested the G2 Pro (in Spanish), folding was less smooth than on many other models – the handlebar has to be in its highest position for the latch to line up. In the same test one charge gave 35–45 km, against the manufacturer’s 55 km.
G4 – the biggest battery for long rides on tarmac
The G4 has the largest battery of the three, 1,200 Wh, and 11-inch pneumatic tyres that roll easily and soak up bumps. It has a single powerful 2,000 W rear motor. The manufacturer quotes 75 km of range, but in Eco mode with a 65 kg rider – in normal riding it will be clearly less. The manual describes the G4 as made for smooth roads, and it has regular pneumatic tyres where the G2 Pro and G2 Master have knobbly off-road tyres.
The price is weight and charging time: 37 kg and 10–12 hours for a full charge. There is no seat.
G2 Master – two motors for gravel and grip
The G2 Master has two 1,000 W motors, one at the front and one at the rear. With both wheels driving you get grip where the surface is loose – gravel, forest tracks and wet leaves. The 1,082 Wh battery is almost as big as the G4’s, and the 10-inch off-road tyres handle rough ground well.
But two motors don’t mean steeper hills: the manufacturer quotes the same 20-degree climb as for the G2 Pro and G4. The G2 Master is also the heaviest, 41.5 kg according to the manual, and is rated IPX4 for water rather than IP54 like the other two.
Weight, range and charging in everyday use
The difference in weight is bigger than it sounds. Most people can carry 26.7 kg up a flight of stairs or lift it into a car. 37 and 41.5 kg are heavy lifts even for a strong person, so the G4 and G2 Master suit you mainly if they are kept in a garage or ground-floor storage.
The range on the product page is measured in favourable conditions. Tom’s Guide’s scooter tester, who lives somewhere hilly and weighs around 90 kg, typically gets 50–60 percent of the advertised range. So compare the batteries: the G4 and G2 Master hold 50–70 percent more energy than the G2 Pro, but they also weigh and use more. The G2 Pro charges in 7–8 hours, the other two in 10–12, so in practice you charge the big models overnight. The battery is fixed on all three, so you need a socket where the scooter is kept.
All three are designed for riders up to 120 kg. If you weigh more, read our guide to the electric scooter for heavy adults.
Which KuKirin should you choose?
- City commuting, sometimes seated: G2 Pro. The lightest, with a seat and the shortest charging time.
- Long rides on tarmac: G4. The biggest battery and wheels, but heavy and without a seat.
- Gravel, forest tracks and loose ground: G2 Master. Two motors give grip, but it is the heaviest of the three.
- Steep hills: none of the three is rated for more than 20 degrees. Our guide to KuKirin shows which models climb more steeply.
You’ll find the whole brand in the KuKirin collection, and all our electric vehicles come with a 2-year warranty. What applies when you ride on public roads is covered in our electric scooter laws in Europe.
