Technical support
After the container lands, this page is your workshop manual.
We would rather you never need to message us with a technical question. Assembly, break-in, service intervals, torque values, fault codes and claims — organised by what happens to a bike after it leaves the port, and by engine platform.
By stage
What happens when, and what to do about it
Five stages, two pages each. Follow them in order for your first container; jump straight in afterwards.

What ships with every unit
- • The manufacturer’s owner’s manual (Chinese + English where the factory prints one; we add an English platform guide when it does not).
- • The PDI video and photo set for that VIN, plus the layer-by-layer loading photos.
- • Fuse map, wiring colour legend and, for EFI units, the diagnostic-code sheet for the ECU fitted.
- • For e-motos: charger spec, controller parameter sheet and error-code list; UN38.3 and MSDS for the battery.
- • A spare-parts kit matched to the models in the container, if ordered (we recommend it on every first container).
Still stuck?
Send the VIN, a photo of the fault and a 30-second video to WhatsApp. A technical reply comes back within 48 hours, usually much faster, in English or Spanish. Faults that turn out to be manufacturing defects go straight into a claim.
Want the manuals before you order?
Every quote comes with the platform guide for each model, so your mechanic can judge the workload before you commit.
