Explore our export-grade single-sided swingarms, integrated electric motorcycle chassis kits, and premium accessories supplied direct from China to New Zealand ports.
As New Zealand accelerates toward low-emission transport under its national decarbonization strategies, the demand for premium urban electric café racers, high-end sportbikes, and rugged utility EV platforms has surged. Central to high-end electric motorcycle architecture is the single-sided swingarm (SSSA)—an engineering masterpiece that eliminates structural mass while dramatically simplifying maintenance.
For New Zealand automotive importers, custom bike workshops, and OEM brands, sourcing high-integrity single-sided swingarms directly from certified Chinese exporters offers an unparalleled competitive edge. Our manufacturing facility combines aerospace-grade 5-axis CNC machining, gravity aluminum casting, and rigorous finite element analysis (FEA) to engineer swingarms engineered specifically for the harsh coastal environments and corrugated topographies of Aotearoa.
Information Gain Key Takeaway: Traditional dual-sided swingarms suffer from uneven chain/belt tension during single-side wheel removal and require extensive disassembly. Our single-sided swingarms feature an offset concentric hub design that maintains carbon belt alignment permanently while allowing 90-second rear wheel swaps.
A deep dive into why our China-manufactured single-sided swingarms lead the global market in structural integrity, unsprung weight reduction, and power transfer efficiency.
Engineered using low-pressure gravity casting combined with T6 heat treatment, yielding tensile strength exceeding 290 MPa. For custom low-volume runs, we utilize 6061-T6 monoblock forged billet CNC machining to guarantee zero internal void porosity.
Our patented eccentric bearing carrier design allows infinite, millimeter-precise drive belt or chain tension adjustments without disturbing the rear brake caliper alignment or changing the motorcycle's wheelbase wheelbase dynamics.
Direct-cast radial caliper lugs designed specifically to accept dual Brembo M4 monoblock calipers and high-resolution Bosch ABS speed sensors, guaranteeing seamless OEM integration for modern high-performance vehicles.
Need custom technical drawings or CAD step files for your New Zealand vehicle homologation process?
From the coastal highways of Northland to the rugged alpine tracks of the South Island, our single-sided swingarms are tailored for New Zealand's unique road conditions and riding culture.
Urban commuters require low maintenance and high aesthetic appeal. Integrated with silent carbon belt drives (Optibelt / Gates Delta Chain), our swingarm assemblies eliminate messy chain lubrication and resist oil splatter during daily damp city rides.
Riding along the Coromandel Peninsula or Bay of Islands exposes components to dense marine salt spray. Our swingarms undergo 720-hour ASTM B117 salt spray testing with micro-pore anodic oxidation coating, preventing galvanic corrosion completely.
Rural Kiwi farms require tough electric workhorses capable of delivering instant 250+ Nm torque across unpaved paddocks. Our heavy-duty single swingarms withstand severe torsional flex under heavy agricultural loads and lateral impacts.
For high-speed enthusiasts racing at Hampton Downs or Ruapuna Motorsport Park, rapid pit-stop rear wheel changing is vital. The single-side hub design permits sub-60-second wheel replacements without altering suspension geometry.
The New Zealand electric two-wheeler sector is experiencing exponential growth, spurred by clean energy mandates, elevated fuel taxes, and a strong culture of outdoor motorsport innovation. Importers and custom motorcycle workshops face strict regulation under the Waka Kotahi NZ Transport Agency (NZTA) Vehicle Inspection Requirements Manual (VIRM).
A side-by-side engineering evaluation demonstrating why single-sided swingarms represent the ultimate upgrade for modern high-performance motorcycles.
| Performance Metric | China Billet/Cast Single-Sided Swingarm | Standard Steel Double-Sided Swingarm | New Zealand Market Impact |
|---|---|---|---|
| Rear Wheel Removal Time | < 90 Seconds (Single Center Nut) | 15 - 25 Minutes (Axle Removal & Re-alignment) | Dramatically reduces workshop service hours in NZ dealerships. |
| Unsprung Mass Reduction | High (Optimized A356-T6 Hollow Structure) | Moderate to Low (Heavy Steel/Tubular Alloy) | Enhanced rear tire contact & traction on unpaved gravel roads. |
| Belt/Chain Alignment Integrity | 100% Fixed Concentric Hub Alignment | Variable (Prone to uneven adjuster bolts) | Extends carbon belt lifespan by over 40% under high torque loads. |
| Exhaust / Motor Clearance | Unobstructed Right Side Silhouette | Restricted Clearance on Both Sides | Enables clean packaging for large hub motors or side exhausts. |
| Corrosion Protection | Micro-Pore Anodized / Epoxy Powder Coat | Standard Paint / Thin Galvanization | Superior longevity in New Zealand's harsh maritime salt climate. |
| Visual & Aesthetic Value | Exotic, High-End Café Racer Aesthetic | Conventional Mass-Market Look | Commands higher retail vehicle margins for NZ e-bike brands. |
We bridge state-of-the-art metallurgical engineering with specialized export services tailored specifically for the Oceania trade corridor. Our factory operates under strict ISO 9001:2015 quality assurance protocols.
Utilizing DMG MORI 5-axis machining centers to achieve structural tolerances within ±0.01mm on bearing journals.
100% X-ray non-destructive inspection of all cast structural nodes to eliminate internal microporosity prior to shipping.
From initial CAD design to 3D printed sandbox casting sample delivery in New Zealand in under 21 business days.
Addressing common queries from New Zealand vehicle manufacturers, importers, custom workshops, and procurement directors.
Direct ocean sea freight from Shanghai or Ningbo to Auckland, Tauranga, or Lyttelton ports takes approximately 14 to 20 days. Air freight options for prototyping batches arrive in New Zealand within 5 to 7 business days via Auckland International Airport.
Yes. Our single-sided swingarms are subjected to FEA stress analysis and static fatigue cycle testing (up to 1,000,000 load cycles). We provide full material test reports (MTR) and physical load test certificates required by New Zealand Low Volume Vehicle (LVVTA) certifiers.
We primarily utilize A356-T6 gravity-cast aluminum alloy or 6061-T6 forged CNC billet aluminum. Both alloys are micro-pore anodized or coated with automotive-grade epoxy powder, delivering exceptional resistance against New Zealand's harsh maritime salt fog conditions.
Absolutely. We manufacture complete rear-end modules including the single-sided swingarm, CNC eccentric hub carrier, heavy-duty stub axle, rear brake disc, Brembo caliper mounting brackets, and custom carbon belt pulleys designed for Gates or Optibelt drives.
We support emerging New Zealand electric motorcycle brands with low MOQs starting at just 10 units for CNC billet swingarms, and 50 units for cast aluminum production runs. Prototyping single units for engineering validation is fully supported.
Our swingarms incorporate a precision CNC eccentric hub carrier housed inside the rear axle clamp. Rotating the eccentric housing adjusts belt/chain tension seamlessly around the motor shaft axis without shifting wheel alignment or rear disk brake geometry.
We offer laser-etched OEM logos, custom anodized colorways (such as Atomic Silver, Racing Green, Matte Anodized Black), custom badging, and bespoke packaging branded directly with your New Zealand business identity.
