KuKirin G2 Master vs G4: Differences & Buying Guide

July 12, 2026

Is the KuKirin G2 Master better than the G4?

Choose the KuKirin G2 Master if you want a dual-motor scooter with a lighter frame. Choose the G4 if you prefer its larger 11-inch tyres and higher manufacturer-claimed top speed. Neither is suitable for Irish public-road use. Check the exact model revision before buying; this comparison excludes the G4 Max.

Searching for “G4 Master”?

Check the full model name on the listing and identification plate. G2 Master, G4 and G4 Max should not be treated as interchangeable models. Compare the current KuKirin catalogue or send Lifty the product link for identification.

KuKirin G2 Master vs KuKirin G4 2026

Two fast, muscular KuKirin scooters, two very different personalities. The G2 Master is the grippy dual-motor all-rounder. The G4 2026 is the bigger, faster cruiser with more top-end attitude. This comparison is for private-land riding where permitted: neither model meets Ireland’s public-road e-scooter limits. Compare the current KuKirin range and check our Irish e-scooter rules guide before choosing.

G2 Master

From €909 factory / €1,008 IPX5

Dual motor grip, lighter feel, better punch for mixed riding.

G4 2026

From €919 factory / €1,018 IPX5

Bigger frame, 11 inch tubeless tyres, stronger high-speed character.

G2 Master or G4: which should you choose?

The G2 Master is our pick for buyers who prioritise dual motors and lower weight. The G4 suits buyers who prioritise larger tyres and a higher claimed top speed. Compare the current specifications, price and storage requirements of the exact versions offered. Use either only on private land where permitted.

Irish weather verdict: from factory, both scooters are only light splash resistant. If you are in Ireland and want either model to be considered a good electric scooter for Irish weather, choose the Lifty Electric IPX5 or IPX6 waterproofing service. It improves wet-weather protection for rain and road spray, but it still does not make any scooter submersible or safe for flood water, pressure washing or deep puddles.

G2 Master Pros

Dual-motor setup gives excellent launch, hill climbing and wet-road confidence after proper waterproofing.
Strong value for riders who want performance without jumping into ultra-premium pricing.
More manageable weight than the G4.
An option for permitted private-land riding and light rough surfaces; not legal on Irish public roads or cycle paths.
Lifty Electric upgrade path includes IPX5/IPX6 waterproofing and brake upgrade options.

G2 Master Cons

Factory IP54 is not enough for serious Irish weather. Choose Lifty Electric waterproofing if rain riding is part of your life.
Mechanical brakes need regular adjustment, especially with spirited riding.
Still heavy at around 33 kg, so stairs and apartments are not ideal.
10-11 hour charging time is not quick.
Unlocked performance is for private land only where legally permitted.

G4 2026 Pros

Higher claimed unlocked speed and a more aggressive cruiser personality.
11 inch tubeless tyres help the scooter feel larger and more stable.
Strong 60V 20Ah battery specification with up to 75 km listed range.
Keystart, indicators and bold visual presence suit riders who want the bigger-machine feel.
Lifty Electric IPX5/IPX6 waterproofing makes it far more sensible for Irish conditions.

G4 2026 Cons

Heavy at around 37 kg. It is not a casual lift-and-carry scooter.
Single 2000W setup does not give the same dual-motor traction feel as the G2 Master.
Factory wet-weather protection should be treated as limited; waterproofing is strongly recommended in Ireland.
12 hour charge time means you need charging discipline.
The higher speed potential demands a mature rider, proper protective gear and legal riding conditions.

Choose G2 Master If

You want the best value performance scooter, stronger hill pull, better traction and a more practical high-power ride for Ireland.

Choose G4 2026 If

You want the bigger, sleeker, faster-feeling cruiser with 11 inch tubeless tyres and more top-end drama.

Choose Waterproofing If

You live in Ireland. Seriously. Lifty Electric IPX5/IPX6 waterproofing is the difference between “nice spec” and “better protected for permitted private-land riding.”

Final Lifty Recommendation

For most riders, the KuKirin G2 Master with Lifty Electric IPX5 waterproofing is the cleaner recommendation. It has dual-motor confidence, strong value and a useful performance balance for permitted private-land riding.

For riders who want the more dramatic machine, the KuKirin G4 2026 with Lifty Electric IPX6 waterproofing is the sportier cruiser choice. It is bigger, heavier and more demanding, but it has the stance and speed character some riders are looking for.

Always follow local laws. Range and speed figures are manufacturer/listed estimates and vary with rider weight, terrain, battery charge, tyre pressure, temperature and riding style. Waterproofing improves protection against moisture ingress, but no electric scooter should be submerged, pressure washed or ridden through flood water.
