Direct factory-engineered mobility solutions built for extreme durability, long-range efficiency, and global regulatory compliance.
Why large-diameter tire design (10-inch to 18-inch Citycoco fat tire configurations) is dominating global commercial fleets, urban transport, and high-performance e-motorcycles.
Small 6.5-inch to 8-inch solid tires exhibit high pitch angles when encountering urban potholes, curb lips, and cobble roads. Big wheel architectures (10-inch pneumatic up to 18x9.5-8 inch fat tires) reduce the angle of attack by over 38%, neutralizing rider fatigue and dramatically lowering chassis stress.
Larger wheel circumferences translate to lower RPM requirement for equivalent ground speed. This operational mechanical advantage directly reduces internal BLDC hub motor heat dissipation, maintaining controller MOSFET stability and delivering up to 18% higher battery energy conversion efficiency.
For B2B importers and micro-mobility operators, maintenance overhead represents the largest operational expense. Big wheel pneumatic and fat-tire setups absorb structural micro-vibrations, preventing solder joint fatigue on BMS boards and reducing warranty return rates to under 0.8%.
Technical Information Gain: Comparative testing reveals that switching from standard 8.5-inch e-scooter tires to 10-inch or 12-inch wide pneumatic tires decreases rolling resistance coefficient (RRC) from 0.025 to 0.016 on uneven urban asphalt, while expanding tire contact patch area by 42% for superior braking stopping distance.
From light 250W city mobility to 35kW high-voltage electric motorcycles, our factory integrates military-grade engineering into mass manufacturing.
Our electric scooter hub motors utilize silicon steel stator laminations (0.35mm thickness) combined with N45SH neodymium magnets rated up to 150°C thermal endurance. Whether deploying 350W 36V, 1000W 48V, or 5000W 60V setups, motor winding efficiency exceeds 91.5% with IP67 waterproofing.
Equipped with grade-A 18650 / 21700 high-energy-density cells (NMC / LiFePO4). Our proprietary Smart BMS provides real-time CAN-bus data logging, passive cell balancing, triple-stage over-current protection, and thermal runaway containment certified under UN38.3 and IEC 62133 guidelines.
Leveraging Zhejiang's premier hardware and mobility cluster to provide unmatched OEM/ODM speed, cost efficiency, and scale.
Situated in Wuyi, Zhejiang, our factory is located within a 30-kilometer radius of specialized steel tubing mills, aluminum alloy casting foundries, automated SMT board manufacturers, and tire molding operations. Raw material sourcing lead times are compressed to under 48 hours.
Frame production relies on multi-axis robotic TIG/MIG welding lines, ensuring structural stress distribution and eliminates human welding defects. Every chassis frame undergoes 100,000-cycle dynamic fatigue testing and 300kg load stress verification before assembly.
We offer full-spectrum private label manufacturing for global brands. From custom hydro-formed deck shapes and bespoke color pantones to custom ECU firmware configuration (speed limits, acceleration curves, Bluetooth App UI customization), we turn concepts into production reality.
Big wheel e-mobility engineered to satisfy specific regional compliance mandates, terrain demands, and commercial operational models.
In dense European and South American metros, 10-inch 600W and 1000W electric scooters offer the optimal balance between high agility, traffic navigation, and curb climbing ability. When fitted with rear cargo racks, courier delivery services achieve lower total cost of ownership (TCO) compared to ICE mopeds.
Featuring 1500W to 35kW high-voltage architectures paired with deep-tread knobby off-road pneumatic tires, these vehicles dominate forest trails, desert dunes, and mountain inclines. Reinforced dual-hydraulic shock absorbers neutralize harsh drops and high-speed G-force spikes.
The YUEMA S-02 250W 24V series utilizes specialized 8-inch high-stability wide-track tires paired with electromagnetic auto-braking transaxles. Ergonomic swivel seats and low center-of-gravity step-through frames grant senior riders independent mobility with zero tipping hazard.
Citycoco fat-tire models (18-inch tires) provide unmatched stability on turf, gravel, and concrete. Widely adopted by golf courses, luxury resorts, security patrol fleets, and industrial warehouse complexes requiring quiet, zero-emission personal transport.
Eliminating import friction for distributors with turnkey regulatory documentation and robust spare-parts availability.
Fully compliant with European standard EN 17128:2020, CE Machinery Directive (MD), RoHS environmental standards, and UL 2272 electrical safety specs. Complete test reports are provided for customs clearance in the EU, USA, UK, Australia, and LATAM markets.
Seamless ocean freight (FCL/LCL), rail freight to Central Europe, and expedited air transport for sample evaluation. We handle UN38.3 lithium battery shipping declarations, MSDS paperwork, and Dangerous Goods (DG) maritime packaging compliance.
We support our wholesale partners with a 1-to-1 ratio of critical spare parts (motor controllers, throttle assemblies, brake pads, hydraulic lines, BMS modules). Direct access to video diagnostic guides and technical field engineering consults.
Explore our complete range of certified electric scooters, citycoco fat tire vehicles, and heavy-duty electric motorcycles.
Technical and commercial answers to help importers, brand owners, and fleet buyers make informed sourcing decisions.
Big wheel electric scooters offer significantly superior stability, higher ground clearance, and improved obstacle roll-over capability on rough city roads, gravel, and unpaved terrain. From a mechanical standpoint, larger diameter wheels require fewer revolutions per kilometer, which reduces motor thermal accumulation, decreases bearing wear, and optimizes lithium battery discharge efficiency for extended travel range.
Our standard MOQ for OEM private label orders typically starts at 50 to 100 units depending on the vehicle class (e-scooter vs high-power electric motorcycle). Customization options encompass custom frame powder coating, laser-etched branding, deck grip tape design, custom LCD/TFT dashboard UI, ECU firmware speed limits (e.g., German 20 km/h eKFV vs US 28 mph Class 3 limits), and specialized battery capacity configurations.
We use Grade-A lithium cells equipped with dynamic multi-layer Smart BMS protection boards. Every battery assembly passes automated cell impedance sorting, thermal cycle testing, overload current cut-off validation, and drop testing. All battery modules carry UN38.3, MSDS, and CE safety certifications, allowing seamless maritime (FCL/LCL) and air transport under Dangerous Goods (DG) Class 9 standards.
Sample production and custom prototype evaluation typically take 7 to 14 working days. Full 20ft or 40ft High Cube container orders are produced and quality-inspected within 25 to 35 calendar days. For recurring OEM partners, we support buffer component stocking in our Wuyi industrial facility to shorten production cycles down to 15 days.
Our products are engineered to comply with European standard EN 17128:2020 (Light motorized vehicles for transportation), CE Machinery Directive 2006/42/EC, Low Voltage Directive (LVD), Electromagnetic Compatibility (EMC), RoHS Directive 2011/65/EU, and North American UL 2272 electrical safety guidelines.
We offer a 12-month structural warranty on main chassis frames, brushless hub motors, and lithium battery packs, alongside a 6-month warranty on controllers and electronic displays. We include a standard 1% to 2% spare parts package (switches, brake pads, throttle levers, lights) with every bulk container shipment and provide direct factory technical engineering support.
