Trolley tube set for S16 / S16 PRO electric unicycle

This is a trolley / telescopic-handle component for Kingsong electric unicycles. The trolley bar lets the rider walk the wheel along when not riding; the assembly slides into its housing and is tuned to the wheel's carry geometry. Repeated extension and impact from rolling the wheel through doors and over kerbs eventually loosen the locking mechanism, and at that point the assembly is replaced as a single service item.

Compatibility is limited to the wheel(s) named in the product title above. Manufacturers occasionally update internal harness keying, hole patterns or panel contour between production batches of the same model, so we recommend confirming the exact wheel revision before purchase. If you have a question about whether your wheel matches this part, contact our team — we keep service references, photos and notes for most of the parts we list, and we can often check the production batch your wheel belongs to before you order.

What this part does and where it fits:

• Spare part for service and repair.
• Compatibility is limited to the model family stated in the title.
• Confirm wheel revision before ordering — manufacturer batches occasionally differ in connector or hole layout.
• Sold through OneRide service-parts channel for riders and workshops across Europe.

Trolley bars absorb impact from rolling the wheel through doors and over kerbs. Replacement restores the carry function and the locking position of the bar.

If you are unsure whether this is the correct part for your wheel, message us with the model name and any revision marking visible on the wheel. We can match parts against the production batch your wheel came from, and we can send service photos and reference shots before you order so you can confirm the fit. Our team handles spare-parts orders for riders and workshops across Europe, and we keep service notes on the parts we list so we can answer follow-up questions about fit and assembly once the part arrives.

If you prefer to leave the repair to a workshop, the part can be sent directly to a service centre once the model and revision are confirmed. We are happy to share fitting notes and a parts list with the workshop in advance so the visit is short and there is no waiting on a follow-up part.

Spare-part replacement on an electric unicycle is generally a sequence of small, model-aware steps rather than a single large repair. Most jobs come down to: identify the failed part, confirm the wheel's production batch, source the matching spare, and re-fit it with the right tools and torque. Riders who run their own service typically rebuild from the outside in — shell pieces, trim, then mudguards, lighting and trolley parts — and leave the controller, battery and motor work for a workshop unless they are experienced with high-voltage assemblies. Doing the job in the right order keeps the wheel clean during disassembly and avoids stressing the harness or seal lines around the larger sub-assemblies.

OneRide ships spare parts to riders and workshops across the European Union and into neighbouring countries on request. We carry parts for the main electric-unicycle families on the European market and order in less common items on request when our supplier still produces them. We stay in touch with the manufacturer on items that have multiple production batches, so when a part has been quietly revised mid-cycle we can tell you which version your wheel needs before you order rather than after.
