KuKirin S1Max Honest Review: Lightest Scooter, But Is It Enough?
At just 16 kg, the KuKirin S1Max stands alone in the KuKirin lineup. It is the scooter you can carry onto a bus, up three flights of stairs, or under your desk without breaking a sweat .
But lightweight comes with trade-offs. A 350W motor, 39 km range, and no front suspension make this a very different machine from the G2 Pro or G2 Master .
The question is simple: Is the S1Max enough for you? This honest review breaks down the pros, cons, and who this scooter is really for.
Quick Specs
The Good 👍
1. Unbeatable Portability
16 kg is the S1Max's biggest selling point. It is the lightest scooter in the KuKirin lineup, and it makes a real difference in daily life .
2. Zero Maintenance Tyres
The 8-inch solid honeycomb tyres are puncture-proof . You never need to:
3. EU Speed Compliant
At 25 km/h, the S1Max is legal on cycle paths in most European countries . No speed limit mode to enable, no worrying about fines.
4. Simple, Reliable Controls
The LED display shows speed, battery, gear, headlight status, and cruise control. The single-button interface is intuitive — no steep learning curve .
The Not-So-Good 👎
1. Limited Hill Climbing
The 350W motor has a maximum climbing angle of 15° . On steep hills, you will feel the power drop off — especially as the battery level decreases .
Real rider experience: Testing with a 70 kg rider, the scooter performed well on flat ground but struggled noticeably on inclines as the battery drained .
2. No Front Suspension
The S1Max has a rear spring shock absorber but no front suspension . On cobblestones or rough roads, you will feel every bump .
One reviewer noted: "Riding on forested, uneven paths isn't comfortable — without suspension, the scooter shakes, and the handlebars begin to vibrate" .
3. Limited Load Capacity
Max load: 100 kg . This is lower than the 120 kg limit on most other KuKirin models. Heavier riders may find the performance affected.
4. Basic Braking System
The electronic brake + auxiliary foot brake is functional, but there are no mechanical disc brakes . Braking distance is 2–4 metres, which is short due to the low speed, but the system feels less precise than disc brakes .
5. No Turn Signals
Unlike the A1 or G2 Pro, the S1Max does not have built-in turn signals . You will need to use hand signals.
