Meet the KOOLUX X7 – the electric bike that refuses to run out of power.
With a massive 48V 25Ah lithium battery, hydraulic disc brakes, and chunky 20×4.0 Kenda fat tyres, the X7 is built for riders who want exceptional range without upgrading to a dual-battery system. One battery. 120km. No compromises.
Who Is This Bike For?
The KOOLUX X7 is perfect for:
-
Long-distance commuters (30-50km each way) who hate charging daily
-
Delivery riders who need maximum uptime and minimal downtime
-
Weekend explorers covering 100km+ on canal paths and country lanes
-
Heavier riders (up to 120kg) – strong frame, stable ride
-
Anyone who wants simplicity – one battery, massive capacity, no juggling two packs
48V 25Ah Battery – The Star of the Show
The X7 features a massive 48V 25Ah lithium-ion battery – one of the largest single-battery capacities available in a UK-legal e-bike.
Real-world range you can trust:
| Riding Mode | Expected Range |
|---|---|
| Low assist (Eco mode) | Up to 120km (75 miles) |
| Mixed riding (Normal) | 90-100km (56-62 miles) |
| High assist / Hilly terrain | 70-80km (43-50 miles) |
Charge time: Just 5-6 hours – surprisingly fast for such a large battery.
No range anxiety. No dual-battery hassle. Just ride.
UK Legal 250W Motor – Power When You Need It
The X7 uses a rated 250W brushless hub motor – fully compliant with UK EAPC regulations:
-
Smooth assistance up to 25km/h (15.5mph)
-
Climbs 25° slopes with ease
-
Quiet, reliable, maintenance-free
No license, no tax, no registration. Just charge, ride, and enjoy.
Hydraulic Disc Brakes – Stop With Confidence
Unlike cheap mechanical brakes, the X7 comes with hydraulic disc brakes front and rear.
Why hydraulic matters:
-
More stopping power – especially in wet UK weather
-
Better modulation – squeeze gently for gradual stop, hard for emergency
-
Less hand fatigue – two-finger braking is enough
-
Self-adjusting – no cable stretching over time
Safety first, always.
20×4.0 Kenda Fat Tyres – All-Terrain Confidence
The Kenda fat tyres (20×4.0 inches) are built for British conditions:
-
Sand, mud, gravel, grass, snow – no problem
-
Puncture-resistant construction
-
Smooths out potholes and rough roads
-
Stable at speed – no wobble on loose surfaces
Rain or shine, tarmac or trail – these tyres grip.
