G2 Master 61-Review Analysis: Tank Build Quality, But Watch for Death Wobble
The KuKirin G2 Master 2025 has generated strong opinions among its riders. Based on an analysis of 61 real user reviews, the picture is clear: this scooter delivers exceptional performance and build quality, but comes with serious caveats that every potential buyer needs to know .
Here is what the data shows: 89% of reviewers gave it 5 stars, praising its power and construction. But the remaining reviews highlight issues that range from inconvenient to potentially dangerous .
The Good: What Owners Love
"Tank" Build Quality — 89% 5-Star Rating
Multiple owners describe the G2 Master as being "built like a tank on wheels" . One reviewer stated: "This is hands down the best e-scooter for the money no question asked. The build feels premium which I did not expect at that price range" .
Key highlights from positive reviews:
Insane Speed — 66 km/h
Owners report a top speed of 66 km/h on flat ground, exceeding the advertised 60 km/h . One rider described it as: "It's f*cking fast with a top speed on flat ground 66km/h and climbs hills like it eats them for breakfast" .
Hill Climbing Beast
The dual-motor setup makes steep inclines effortless . One reviewer noted it "climbs hills like it eats them for breakfast" .
The Bad: What Owners Complain About
Real-World Range — A Significant Gap
The official range is 70 km. The real-world range? 25-30 km with normal use, according to multiple owners .
One 107 kg rider reported: "It easily carries my 107 kg, although the range is not quite 60 but I can't expect it to travel that far with a load, terrain, wind, etc."
He was being generous — most riders are seeing much less.
The Death Wobble — The Biggest Safety Concern
Multiple owners report a serious issue at high speeds. One reviewer warned: "Last but not least is the death wobbles I get after 55km/h" .
Death wobble is a violent, escalating oscillation in the front wheel that can start after hitting a bump at speed. At 55+ km/h, it can be genuinely dangerous.
Safety note: The only reliable way to stop a death wobble is to slow down and bring the scooter to a controlled stop. Do not slam on the brakes — just reduce speed gradually.
The good news: Some owners have reported that suspension adjustments can help. One reviewer noted: "The suspension is so stiff that you almost can't have a comfortable ride (can be loosened with some tools and makes a huge difference)" .
Stiff Suspension — But Adjustable
Several owners complain about the suspension being too stiff out of the box . One reviewer said: "The suspension is so stiff that you almost can't have a comfortable ride" .
Fix: The suspension can be loosened with tools, and owners report it makes "a huge difference" .
Charger Noise — "Normal" According to Community
One owner noted: "The charger sounds strange but in the comments on R. they say that's how it should be" . Multiple users report this, suggesting it is a design quirk rather than a defect.
The Tragic Context
In August 2026, an 11-year-old boy in Estonia died after crashing a KuKirin G2 Master. According to police reports, he lost control on a straight road, was not wearing a helmet, and may have been exceeding the speed limit .
The manufacturer states the G2 Master's top speed is up to 60 km/h . This tragedy underscores the importance of:
-
Wearing a helmet at all times
-
Understanding the scooter's power and speed
-
Age-appropriate use
-
Riding within your skill level
