KOOLUX X9 Mini 500 W – compact electric fat bike for city and leisure
The KOOLUX X9 Mini is a compact yet robust electric fat bike that combines the stability of wide tires with the agility of a compact electric bike. Its 500W rear hub motor, 48V 13Ah battery and 16×4,0 inch fat bike tires form a practical package for commuting, city riding and leisure trips.
The X9 Mini is perfect for riders who want an easy-to-manage electric bike without the heavy feel of a large 26-inch electric fat bike. The smaller tires make the bike agile, but the four-inch width helps maintain balance and traction on varying surfaces.
🔥 500W rear hub motor
The KOOLUX X9 Mini is equipped with a 500W motor located in the rear wheel hub. The rear hub motor provides a pushing and natural-feeling electric assist for city streets, bike paths, and gentle off-road trails.
The manufacturer's current EU product page lists the model's maximum speed as 32 km/h. However, speed and product usage options may vary depending on the delivery version, settings and local traffic regulations.
🔋 48V 13Ah battery
The electric bike has a 48 V 13 Ah lithium battery with a calculated energy capacity of 624 Wh. The battery offers enough capacity for daily commuting and longer leisure routes.
The manufacturer states that the assisted range is approximately 60–80 kilometers on a single charge. The actual range depends on factors such as the rider's weight, temperature, terrain, tire pressure, driving speed, and the assistance level used.
The stated battery charging time is approximately 7–8 hours.
🛞 Wide 16×4,0 inch fatbike tires
The X9 Mini's 16×4,0-inch tires make it low, agile, and easy to handle. The wide tire provides a larger contact patch than a typical city bike tire, which increases stability and traction.
The KOOLUX X9 Mini electric fat bike is suitable for:
- for city streets and bike paths
- for commuting
- gravel roads
- for hard-surfaced forest paths
- for leisure trips
- for varying and uneven driving surfaces
Despite its compact size, the wide tires give the bike the appearance of a sturdy and impressive electric fat bike.
🛑 Mechanical brakes
KOOLUX X9 Mini is equipped with mechanical brakes. The mechanical braking system is simple in structure, easy to adjust, and usually inexpensive to maintain.
It is a good idea to check the brake adjustments and the condition of the brake pads regularly, especially if the e-bike is used daily or in changing weather conditions.
🚲 Compact electric bike for everyday trips
As its name suggests, the X9 Mini is more compact than a regular electric fat bike. The overall dimensions of the bike when ready to ride are approximately 135 × 63,5 × 106 cm.
The smaller frame and 16-inch tires make the electric bike agile on busy city routes and easier to store than large electric mountain bikes.
The net weight of the bike is approximately 34,7 kg and the maximum load is 120 kg.
💧 IP54 protection
The KOOLUX X9 Mini has an IP54 protection rating, meaning it is protected against dust and water splashes from all directions.
However, the bike should not be submerged in water, washed with a pressure washer, or left in heavy rain for long periods of time. It is best to keep the electrical connections, battery, and display as dry as possible to extend their lifespan.
