Performance Analysis: Pushing the KuKirin G4 Scooter to Its Limits

First Impressions: A Speed Demon on Wheels

Let me start by saying this: the KuKirin G4 electric scooter is no joke. I’m wearing my helmet for a reason—this thing is fast. Like, keep up with city traffic fast.

We’re talking a 60V 20Ah battery powering a 2000W brushless motor, with a claimed top speed of 70 km/h (43 mph). And let me tell you, it delivers. I’ve hit 82 km/h (51 mph) on a full charge, and the acceleration is brutal.

Specs & Build: A Heavyweight Beast

• Motor: 2000W brushless

• Battery: 60V 20Ah

• Top Speed: 70 km/h (claimed, but I’ve hit 82 km/h)

• Range: 75 km (claimed), ~55-58 km real-world (I’m 6’3”, 215 lbs)

• Weight: 37 kg (81 lbs) – not a commuter-friendly carry

• Tires: 11-inch tubeless (but not great for off-road, despite claims)

• Brakes: Mechanical disc (not hydraulic—a downside at these speeds)

• Water Resistance: IPX4 (don’t ride in the rain)

The frame is all aluminum alloy, making it sturdy as hell at high speeds. No flex, no wobble—just pure stability.

The Ride: Keeping Up With Traffic

I took this thing onto city streets, and within seconds, I was matching car speeds.

• Eco Mode: Capped at 20 km/h (12 mph) – useless unless you're in a crowded area.

• Sport Mode: 40 km/h (25 mph) – decent for casual riding.

• Race Mode: Unlocks the full 70+ km/h – this is where the fun begins.

I merged into traffic, hitting 60 km/h (37 mph) effortlessly. A bus tailed me, cars flowed around me—I was just another vehicle on the road.

But here’s the catch: the front-wheel drive makes hill climbing questionable. I haven’t tested steep inclines yet, but I’m skeptical.

The Downsides

1. Throttle Issues – Mine was sticky out of the box. Kieran sent a replacement within 6 days (great customer service).

2. Brakes – Mechanical discs at these speeds? Not ideal. Hydraulic upgrades would be a smart move.

3. Weight – 81 lbs is not apartment-friendly.

Final Verdict: Who Should Buy This?

Get the KuKirin G4 if:

✅ You want a street-focused speed machine.
✅ You have a garage (carrying 81 lbs upstairs sucks).
✅ You’re okay with mechanical brakes (or willing to upgrade).

Skip it if:

❌ You need off-road capability (look at the G2 Master instead).
❌ You live in a walk-up apartment.
❌ You want dual motors for hill climbing.

The Bottom Line

This scooter is insanely fun—like riding a pit bike, but electric. If you want speed, stability, and a thrill, the G4 delivers. Just wear a helmet.
