But which one is right for you? The featherweight S1 Max prioritises portability above all else. The more powerful M4 Max offers higher speed and longer range while still being relatively light.

KuKirin S1 Max: The Ultra-Portable City Runner

The S1 Max is all about one thing: getting from A to B with minimal fuss and maximum portability. It's the scooter you grab when you need to hop on a train, carry it up to an apartment, or stash it under a desk.

Why Choose the S1 Max?

1. Incredibly Lightweight (16 kg)
At just 16 kg, the S1 Max is the lightest scooter in the entire KuKirin range. You can carry it with one hand, lift it onto a bus, or take it up three flights of stairs without breaking a sweat. For students, apartment dwellers, and multi-modal commuters, this is a game-changer.

2. Puncture-Proof Solid Tyres
The 8" solid honeycomb tyres never go flat. No air pressure to check, no punctures to repair. On glass-strewn city streets, this is a massive advantage. Just ride and forget.

3. Simple, Intuitive Controls
All settings are controlled through a single power button with multiple press combinations. Short press to change gears, double press for lights, triple press for cruise control. It's simple, reliable, and easy to learn.

4. Perfectly Legal for EU Roads
With a top speed of 25 km/h, the S1 Max is fully compliant with EU electric scooter regulations. No speed limit mode to worry about – it's ready to ride straight out of the box.

5. Very Affordable
The S1 Max is one of the most budget-friendly KuKirin models. You get excellent build quality and reliable performance without breaking the bank.

Where the S1 Max Falls Short:

• Limited range (39 km): Fine for short commutes, but not for all-day exploring

• No front suspension: The ride can be firm on rough roads

• Lower weight limit (100 kg): Not ideal for heavier riders

• Smaller 8" tyres: Less stable at speed than larger tyres

KuKirin M4 Max: The Lightweight Performer

The M4 Max takes a different approach. It's still portable (24 kg is manageable for most adults), but it packs significantly more power and range. Think of it as the "lightweight" option for riders who don't want to sacrifice performance.

Why Choose the M4 Max?

1. Genuine 45 km/h Top Speed
The 800W motor (peaking at 1000W) delivers real speed. At 45 km/h, you'll keep up with city traffic and arrive at your destination faster. For riders who find 25 km/h too slow, the M4 Max is the answer.

2. Excellent 64 km Range
With a 48V 18.2Ah battery, the M4 Max can handle a full day of errands, a longer commute, or a weekend exploration ride. You won't be constantly watching the battery gauge.

3. Proper Suspension
Unlike the S1 Max, the M4 Max features both front and rear spring suspension. This makes a noticeable difference on cobblestones, cracked pavement, and uneven roads. Your ride will be smoother and less fatiguing.

4. Larger 10" Vacuum Tyres
The 10" tyres roll over obstacles more easily than the S1 Max's 8" tyres. They also provide better stability at speed and more grip in corners.

5. Full Disc Brakes
Front and rear disc brakes (plus electronic brake) provide confident stopping power. The braking distance of 6-8 metres at top speed is respectable for a scooter in this class.

Where the M4 Max Falls Short:

• Heavier than S1 Max (24 kg): Still portable, but you'll notice the extra 8 kg

• Longer charging time (9-10 hours): Overnight charging required

• Larger folded size: Takes up more space in a car boot or under a desk

Frequently Asked Questions (FAQ)

Q1: Which scooter is lighter – S1 Max or M4 Max?

A: The S1 Max is significantly lighter at 16 kg compared to the M4 Max at 24 kg. If you need to carry your scooter regularly, the S1 Max is the clear winner.

Q2: Can the S1 Max handle hills?

A: The S1 Max has a 15° climbing ability. It can handle gentle slopes but will struggle on steeper hills. The M4 Max's 20° climbing ability is noticeably better.

Q3: Are the S1 Max's solid tyres comfortable?

A: Solid tyres are firmer than pneumatic (air-filled) tyres. The ride is acceptable on smooth pavement but can feel bumpy on rough roads. The M4 Max's 10" vacuum tyres with suspension provide a much smoother ride.

Q4: Does the M4 Max come with a seat?

A: Yes, the M4 Max includes a detachable seat. This is a great feature for longer rides. The seat is easy to remove when you want to stand.

Q5: Which scooter has better range for summer rides?

A: The M4 Max with 64 km range – nearly double the S1 Max's 39 km. For longer summer adventures, the M4 Max is the better choice.

Q6: Can I ride these scooters in the rain?

A: Both have IP54 water resistance – fine for light rain and splashes. Avoid heavy downpours and deep puddles. The S1 Max's solid tyres are unaffected by wet roads.

Q7: Which scooter fits on a crowded train or bus?

A: The S1 Max has a smaller folded size (1082×500×460 mm) and lighter weight, making it much easier to manage on crowded public transport.

A: At 20-25°C with a 70 kg rider:

Expect 10-20% less range in very hot weather (35°C+).

• S1 Max – Best value for ultra-portability and budget
