The KOOLUX X9 Mini is a compact electric bike featuring a 250W motor, 48V 13Ah battery, and 16 × 4.0-inch wide tyres. Its compact frame combines electric pedal assistance with a stable tyre profile and suspension designed to help absorb bumps and uneven surfaces.

The 250W electric motor provides assistance up to a manufacturer-stated maximum of 25 km/h. A 48V 13Ah battery supplies the electrical system, with a published range of approximately 40–60 km depending on load, terrain, assistance level, weather and other riding conditions.

Is the KOOLUX X9 Mini an EAPC?

The published specifications state a 250W motor and maximum assisted speed of 25 km/h, corresponding with two key UK EAPC thresholds. EAPC classification also requires pedals capable of propelling the cycle, compliant motor assistance behaviour, required markings, and all other applicable requirements. The exact UK-market configuration should therefore be confirmed before relying on EAPC classification.

Off-road Compliance Notice

The over-250W notice is not applicable to the manufacturer's published X9 Mini specification. The product is listed with a 250W motor and maximum assisted speed of 25 km/h.

For Great Britain, an EAPC must have pedals capable of propelling the cycle, a maximum continuous rated motor power not exceeding 250W, and electrical assistance that stops at 15.5 mph (25 km/h). The cycle must also meet applicable marking and construction requirements.

Do not modify or de-restrict the motor, controller, or assistance-speed settings. Increasing motor assistance beyond the applicable power or speed thresholds can change the legal classification of the product and may introduce additional registration, approval, insurance, and licensing requirements.
