Who Is This Bike For?

The KOOLUX X11S is perfect for:

  • Safety-conscious commuters – hydraulic brakes stop faster in wet weather

  • Long-distance riders – 150km range means ride for days without charging

  • Delivery professionals – dual batteries = maximum uptime, maximum earnings

  • All-terrain explorers – fat tyres + suspension + hydraulic brakes = total confidence

  • Caravan and motorhome owners – folding frame + UK/EU stock = holiday ready

Secondary battery 48V 10.4Ah Rear rack mounted
Total 48V 23.4Ah (1123Wh)

Real-world range you can trust:



Riding Mode Expected Range

Mixed riding (Normal) 110-130km (68-80 miles)
High assist / Hills / Fat tyres 80-100km (50-62 miles)

Removable, swappable, chargeable anywhere. No range anxiety. Just ride.


Hydraulic Disc Brakes – Premium Stopping Power

This is the key differentiator of the X11S. Unlike mechanical disc brakes found on most folding e-bikes, the X11S comes with hydraulic disc brakes front and rear.

Why hydraulic brakes matter:



Feature Hydraulic Brakes Mechanical Brakes
Stopping power Superior Moderate
Wet weather performance Excellent Average
Hand fatigue Minimal (2-finger braking) High (4-finger braking)
Maintenance Self-adjusting Manual cable adjustment
Modulation Smooth, progressive Grabby or vague
Safety margin High Standard

In wet UK weather, on steep hills, or in emergency stops – hydraulic brakes can make all the difference.


UK/EU Legal 250W Motor – Power Meets Compliance

The X11S uses a rated 250W brushless hub motor – fully compliant with UK and EU EAPC regulations:

  • Smooth assistance up to 25km/h (15.5mph)

  • Climbs hills effortlessly – even with dual batteries and cargo

  • Quiet, reliable, maintenance-free

  • Integrated speed sensor for accurate assistance

No license, no tax, no registration. Just fold, ride, and enjoy.


20×4.0" Built-up Fat Tyres – All-Terrain Confidence

The 20×4.0" built-up fat tyres are engineered for versatility:

  • Urban roads – smooth, stable, puncture-resistant

  • Gravel and canal paths – excellent grip and shock absorption

  • Mud and grass – fat tyres float over soft surfaces

  • Potholes and rough tarmac – cushioned ride, less fatigue

Built-up construction means enhanced durability and puncture protection.


Shimano 7-Speed Gearing + Integrated Speed Sensor

The Shimano 7-speed gear system gives you reliable, precise shifting:

  • Low gears for steep hills and heavy loads

  • High gears for efficient cruising on flats

  • Smooth, dependable shifting from a world-leading brand

The integrated speed sensor ensures accurate speed and distance tracking on the LCD display.


Suspension Fork – Front-end Comfort

The suspension fork absorbs bumps, vibrations, and impacts:

  • Less fatigue on long rides

  • More control on loose or uneven surfaces

  • Protects wrists and hands from jarring impacts

Fat tyres + suspension fork = luxury comfort on any terrain.


Sturdy Iron Frame – Built to Last

The X11S uses a sturdy iron frame that prioritises durability:



Benefit Why It Matters
Extreme durability Withstands years of folding/unfolding
High strength Supports heavier riders and cargo
Stable at speed Less flex than aluminium
Foldable design Folds for storage without compromising strength

Note: Iron is heavier than aluminium but significantly more durable. The X11S is built for riders who prioritise longevity and strength over minimal weight.


LCD Display – Information at a Glance

The LCD display shows everything you need:

  • Current speed

  • Battery level (both batteries)

  • Distance travelled

  • Pedal assist level

  • Riding mode

Easy to read in sunlight or rain.


Folds for Easy Storage

The X11S folds quickly and compactly:

  • Fits in car boots – take it to the trails

  • Fits on trains and buses – multi-modal commuting

  • Fits in small flats – store indoors, safe from theft

  • Fits in caravans/motorhomes – bring it on every trip

Premium features shouldn't mean premium storage headaches.

No waiting for container ships. No customs delays.

The X11S is stocked in UK and EU warehouses, meaning:

  • Fast delivery – days, not weeks
