KuKirin S1Max Honest Review: Lightest Scooter, But Is It Enough?

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.

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 .



Scenario Why It Matters
Public transport Carry it onto buses, trains, or the metro without strain 
Stairs Easy to carry up to apartments or lecture halls 
Storage Folds to 1082×500×460mm — fits under desks or in small spaces 

2. Zero Maintenance Tyres

The 8-inch solid honeycomb tyres are puncture-proof . You never need to:

  • Check tyre pressure 

  • Fix a flat 

  • Carry a pump 

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.


Who Is the S1Max For?

✅ Best For



User Type Why
Students Light enough to carry between classes, store in dorms 
Short-distance commuters 39 km range covers 15 km round trips with buffer 
Last-mile riders Easy to take on public transport 
First-time riders Simple controls, lower speed 
Frequent carriers 16 kg is manageable for stairs or trains 

❌ Not For



User Type Why
Long-distance commuters 39 km range may not cover longer trips
Hilly cities 15° climbing limit struggles on steep terrain 
Heavier riders (near 100 kg) Performance and range will be reduced
Rough terrain riders No front suspension makes cobblestones uncomfortable 
Those needing turn signals Not included — use hand signals 

Real-World Range: What to Expect

Official range is 39 km under ideal conditions (65 kg rider, mid-speed, flat terrain) .



Condition Expected Range
Light rider, flat, moderate speed ~35-39 km
70 kg rider, full throttle, mixed terrain ~28 km 
Hilly route Significantly less
Near max load (100 kg) Reduced range

Frequently Asked Questions (FAQ)

Q1: Is the S1Max good for students?

Yes — the 16 kg weight makes it ideal for campus commuting. It is light enough to carry into lectures and stores easily in dorm rooms .

Q2: Can the S1Max handle hills?

Limited — it can handle slopes up to 15°. Steeper hills will be a struggle, especially with a full battery already partially drained .

Q3: Do I need to maintain the tyres?

No — the solid honeycomb tyres are puncture-proof and require zero maintenance .

Q4: Is the S1Max legal in Europe?

Yes — the 25 km/h top speed complies with EU speed limits for cycle paths .

Q5: What is the real-world range?

With a 70 kg rider at full throttle, expect around 28 km. Lighter riders on flat terrain can get closer to the official 39 km .

Q6: Why is the S1Max cheaper than the G2 Pro?

The S1Max has a smaller motor (350W vs 600W), smaller battery (36V 10.4Ah vs 48V 15.6Ah), less suspension, and fewer features like turn signals and disc brakes .


Conclusion: Lightweight Wins, If That Is Your Priority

The KuKirin S1Max is a scooter with a very clear purpose: ultra-portable urban commuting.



Factor Verdict
Portability ⭐⭐⭐⭐⭐ Best in lineup
