KuKirin G4 Review: Is This 70km/h Beast Legal in Europe?
Introduction: The Scooter That Pushes the Limits
The KuKirin G4 is not your average electric scooter. With a 2000W motor and a top speed of 70 km/h, it is one of the most powerful scooters you can buy in Europe . It looks more like a compact electric motorcycle than a traditional commuter scooter .
But here is the question every potential buyer needs to ask: Can I actually ride this thing on European roads?
This review covers everything you need to know about the G4 — the incredible performance, the ride experience, and the critical legal reality of owning a 70 km/h scooter in Europe.
Core Specifications
Performance: The 70 km/h Experience
Speed Modes
The G4 offers three distinct riding modes :
| Mode | Speed | Best For |
|---|---|---|
| Eco | ~20 km/h | City streets, battery saving |
| Sport | ~40 km/h | Everyday commuting |
| Race | 70 km/h | Open roads, thrill-seeking |
In Race mode, the acceleration is described as "smooth but very strong" — not an aggressive jerk, but a powerful launch that pushes you back . One reviewer hit nearly 80 km/h downhill .
Range: 75 km Official, 50 km Real-World
The 60V 20Ah battery delivers up to 75 km under ideal conditions . In mixed riding with hills and city traffic, expect closer to 50 km . This is still impressive for a scooter this powerful.
Ride and Comfort: Built for the Open Road
Suspension and Tires
The G4 features front and rear dual shock absorbers and massive 11-inch tubeless tires . This combination makes the ride "incredibly smooth," handling potholes and rough roads with confidence . One reviewer noted it handles gravel, cobblestones, and even wet grass without slipping .
Weight and Portability
At approximately 37 kg, the G4 is heavy . This is not a scooter you carry up three flights of stairs or casually toss into a car boot. The weight comes from the large battery, powerful motor, and steel-aluminium alloy frame .
The trade-off: The weight makes it stable at high speeds but impractical for mixed commutes involving stairs or trains .
European Legality: The Critical Warning
The 25 km/h Problem
In most EU countries, electric scooters are limited to 25 km/h on public roads . Finland recently passed legislation limiting scooters to 25 km/h and imposing alcohol limits similar to car drivers . Spain's Barcelona has already implemented 25 km/h speed limits for scooters . The EU EN 17128 standard requires scooters to comply with speed regulations .
The G4 reaches 70 km/h. This means it is not street-legal in most European countries.
What Happens If You Ride It on Public Roads?
The G4 can be unlocked to 70 km/h in Race mode, but:
-
It exceeds the 25 km/h limit in almost all EU countries
-
It is classified as a moped or motorcycle rather than a scooter
-
You need registration, insurance, a licence plate, and a helmet
-
Riding it unregistered can result in fines up to €500 and confiscation

Conclusion: Thrill Ride or Legal Headache?
The KuKirin G4 is an incredible piece of engineering. The 2000W motor, 70 km/h speed, and 75 km range deliver an exhilarating ride that few scooters can match .
But in Europe, the G4 is a legal dilemma. It is too fast for public roads, too heavy for carrying, and too powerful for most scooter regulations .
Before you buy: Ask yourself where you will actually ride it. If you have access to private land, tracks, or rural roads where speed limits do not apply, the G4 is a fantastic purchase. If you need a legal daily commuter for European city streets, consider the G2 Pro VMP (25 km/h, DGT certified) or the G2 Pro ABE (20 km/h, ABE certified) instead.
The G4 is a beast. Just make sure you have a place to let it run.
