At 5TH WHEEL, product quality isn't an afterthought—it's a core promise. From urban commutes to rugged terrain, every electric bike and electric scooter we produce is built for performance, durability, and safety. This is made possible by our independent testing lab, advanced automated manufacturing equipment, and a fully implemented ISO 9001 quality management system.
Let's take a closer look at how our manufacturing and testing systems guarantee long-lasting reliability for every ride.
Independent Testing Lab Built for Real-World Durability
Before our e-bikes and e-scooters reach the road, they're tested in-house under extreme, real-world simulations. Our lab covers every stress point—from frame strength to motor power.
Core Testing Equipment for eBike & eScooter Reliability:
- Dynamic Fatigue Testing Machine: Simulates long-term riding stress on bike frames and scooter decks.
- Double Drum Road Simulation Tester: Recreates different terrains for continuous ride fatigue.
- Complete Vehicle Testing Rig: Assesses braking, acceleration, and structural load performance.
- Drop Test Machine: Tests packaging and structural integrity during shipping or accidental drops.
- Frame Vibration Testing System: Measures how frames handle bumps, potholes, and uneven roads.
- Motor Dynamometer: Verifies motor torque, efficiency, and thermal performance.
- Folding Mechanism Tester: Ensures foldable handlebars on scooters lock and unlock securely over repeated use.
These rigorous tests ensure that both e-bikes and e-scooters can withstand daily use and harsh riding environments, delivering the confidence customers expect.
Automated Production for Precision and Consistency
Our 20,000 m² factory is engineered for both scale and precision, with an annual capacity of 300,000 units. Our fully automated wheel assembly lines reduce human error while improving efficiency and uniformity.
Automation Equipment Highlights:
- Automatic Wheel Spoke Lacing and Locking Machine
- Wheel Tension Adjustment and Truing Robots
- Rim Calibration Robots with Real-Time Feedback
- Steel Wire Tightening and Positioning Machines
This level of automation guarantees consistent wheel balance, spoke tension, and long-term ride safety, critical for both eBike and eScooter performance.
Certified Quality: ISO 9001 + Total Quality Management
Our facility operates under ISO 9001 and a Total Quality Management (TQM) framework. From incoming materials to final product inspection, we follow standardized processes that ensure consistent quality and full compliance with international standards.
Every team member is trained in quality-first thinking, while feedback loops across departments help us improve continuously.
Unique Product Code for Every Unit
Every 5TH WHEEL product is assigned a unique identification code based on our proprietary system. This enables:
- Full production traceability
- Quick identification of affected batches
- Streamlined inventory and sales management
- Transparent quality tracking for end-users
With this traceable system, we don't just manage risks—we build customer trust.
Why It Matters to Riders and Resellers
When buying an electric bike or scooter, customers look for safety, reliability, and performance. Our testing equipment, automation technology, and quality protocols ensure fewer warranty claims, better user experiences, and longer product lifespans.
Whether you're a distributor, a reseller, or a rider, 5TH WHEEL delivers the peace of mind you deserve.
