Frequently asked questions

Is the motor power rated or peak?
The supplier specifies 250W rated output and 500W peak output. These are different measurements; peak output is not the continuous rating.

Which battery does it use?
This X9 Mini version uses a 48V 13Ah lithium-ion battery, equivalent to 624Wh nominal capacity. Do not confuse it with the larger dual-battery X9 Pro.

How long does charging take?
The model-specific table lists approximately 7–8 hours. Use the compatible supplied charger and follow the battery-care instructions.

What tyre size is fitted?
The specified tyres are 16 × 4.0-inch pneumatic fat tyres. Check pressure and condition regularly; do not assume a tube, tyre or wheel for another X9 edition will fit.

Which brakes are fitted?
Front and rear disc brakes are specified. Check both brakes and all wheel fasteners before riding and follow the supplied maintenance instructions.

Is it waterproof?
No. The supplier lists IP54, which does not allow immersion or pressure washing. Keep charging equipment dry and follow the manual’s weather guidance.

What are the weight and load limits?
The supplier lists a 34.7kg net weight and a 120kg maximum load. Consider both rider and carried items, and check safe control reach and handling before use.

How large is the bike?
The listed unfolded dimensions are 135 × 63.5 × 106cm. The shipping carton is listed at 120 × 31 × 76cm; carton size is not a folded-bike measurement.

Is public-road use guaranteed?
No. A stated motor rating and speed do not establish approval for every country. Check the exact delivered configuration and local requirements before riding.

Can I order a sold-out colour?
No backorders are enabled. A colour with zero supplier stock is shown as sold out and must not show an in-stock dispatch or delivery promise.
