The KOOLUX X7 is a robust electric bike built on wide 20×4.0" Fat Bike tires , which provide excellent stability and comfort on asphalt, gravel and lighter terrain.

The heart of the bike is a 750 W rear hub motor powered by a large 48 V / 25 Ah battery . The manufacturer states a range of approximately 80–120 km and a maximum speed of up to 50 km/h with the appropriate configuration.

A big advantage is the hand throttle . The KOOLUX X7 has it as standard equipment, so the engine can be controlled from the handlebars without having to pedal .

Battery 48V / 25Ah

The KOOLUX X7 has a large lithium battery with a voltage of 48 V and a capacity of 25 Ah , i.e. approximately 1,200 Wh of energy.

The battery is removable, so it can be conveniently charged off the bike. The manufacturer states a charging time of approximately 5–6 hours and a maximum assisted range of 80–120 km . 

Actual range depends on rider weight, terrain, speed, temperature, tire pressure, and engine usage.

Hand throttle – driving without pedaling

Hand throttle: YES

This is an important feature of the KOOLUX X7. The manufacturer lists Throttle directly in the package contents.

Using the hand throttle, the rider can activate the engine without pedaling .

PASSPORT: YES

The bike is also designed for classic riding with pedal assist.

Powerful 750 W motor

The 750W rear hub motor gives the X7 plenty of power for a brisk ride and climbing.

The motor in the rear wheel also enables a simple drive design and efficient power transfer to the road.

The official KOOLUX website lists a maximum speed of 50 km/h for this version . 

20×4.0" Fat Bike Tires

The wide 20×4.0" tires are one of the X7's biggest strengths.

Large tire volume provides:

• excellent stability,
• better damping of inequalities,
• high adhesion,
• comfortable ride,
• better handling of gravel and unpaved roads.

The X7 is suitable not only for the city, but also for cycle paths, country roads or lighter terrain.

Hydraulic brakes

Hydraulic disc brakes ensure safe stopping .

The hydraulic system allows for precise dosing of braking force and provides sufficient power even with a higher weight of the bike and rider.

Practical carrier and utility equipment

The KOOLUX X7 is also designed as a practical bike for everyday use.

The European specification lists a front rack and a rear rack , making the X7 suitable for shopping, carrying luggage or daily commuting.
