The ETB-700 Series is an engineered electric touring bicycle platform built for long-distance endurance, mixed-terrain utility, and heavy payload capacity. Designed specifically for B2B brands and fleet operators requiring reliable mid-drive or high-torque hub configurations, this model integrates a structural 6061-T6 aluminum frame, integrated down-tube battery architecture, and pre-engineered mounting eyelets for front and rear cargo racks, fenders, and side panniers.
Production utilizes automated robotic welding for frame structural integrity and strict EN 15194 / ISO 4210 testing protocols to ensure immediate market compliance across European and North American regulatory environments.
Key Features
Integrated Down-Tube Battery Bay: Fully enclosed internal compartment shields the battery pack from mechanical impact, road salt, and moisture ingress while maintaining a balanced center of gravity for loaded riding.
Integrated Cargo Mounts: Brazed-in and CNC-machined threaded eyelets on seat stays, dropouts, and fork blades rated for up to 25 kg rear cargo and 10 kg front load.
Torque-Sensing Pedal Assist: Bottom-bracket integrated torque sensor measures rider input frequency and force at 1,000 Hz, eliminating motor lag and optimizing power delivery across steep inclines.
Internal Cable Routing: Full-length internal routing channels protect shifting cables and hydraulic brake lines from trail debris, tension friction, and weather degradation.
High-Output Lighting Integration: Hardwired front and rear LED illumination powered directly by the main drive battery, featuring a rear brake-activation pulse sensor.

Applications
Long-Distance Bicycle Touring: Optimized geometry with a relaxed 70-degree head tube angle and long chainstays (475mm) ensures stable tracking at high speeds when fully loaded with camping or expedition gear.
Urban Commuting & Utility Transport: Designed to navigate urban asphalt, potholes, and tram tracks safely while carrying heavy laptop bags, groceries, or commercial courier loads.
Eco-Tourism & Commercial Rental Fleets: Ruggedized component selection minimizes recurring maintenance overhead for hospitality operators running multi-day guided cycling tours.
Manufacturing & Quality Control
Production takes place in our 25,000-square-meter facility equipped with automated CNC tube-cutting lasers, robotic MIG/TIG welding cells, and dedicated wheel-building lines.

Robotic Frame Welding and Structural ISO Fatigue Testing Setup.
Frame Structural Testing:
Every frame batch undergoes dynamic fatigue testing according to ISO 4210 standards, enduring 100,000 vertical load cycles at 1,200N force before assembly approval.
Battery Safety Validation:
BMS (Battery Management System) boards undergo 100% automated optical inspection (AOI) followed by a 4-hour thermal chamber burn-in test at 45°C to detect potential cell degradation or soldering flaws.
Water Resistance Testing:
Fully assembled electrical systems pass through an automated spray-tunnel test simulating heavy rain conditions to verify IPX5 water ingress protection across controllers, displays, and wiring harnesses.
OEM / ODM Customization
We provide end-to-end customization services tailored to private label bicycle brands and institutional buyers:
Frame Geometry & Branding: Custom mold development for top-tube gussets, integrated head tubes, laser-engraved brand logos on dropouts, and custom powder-coat color matching (Pantone/RAL references).
Electrical Configuration: Proprietary firmware tuning for torque sensor sensitivity curves, top-speed cutoffs (25 km/h vs. 32 km/h), and custom boot-up display logos.
Component Specification: Modular substitution of drivetrain components, saddle types, handlebar configurations, and tire casings to meet specific retail price points or regional preferences.
Packaging & Logistics
Export Packaging: Each bicycle is partially disassembled (front wheel, handlebar, pedals removed) and packed into a 7-layer reinforced corrugated export carton with molded EPE foam padding to prevent transit shock.
Container Loading Capacity:
• 20ft GP Container: Approx. 70 units (SKD 85%)
• 40ft HQ Container: Approx. 165 units (SKD 85%)
Lead Time: 35 to 45 days for standard production runs; 60 days for initial OEM custom color and firmware orders.

FAQ
Q: What compliance certifications are provided for the European and North American markets?
A: The bicycles are manufactured to comply with EN 15194 for EPACs in Europe and UL 2849 for electrical system safety in North America. Full test reports issued by ISO/IEC 17025 accredited laboratories (such as SGS or TÜV) are supplied with every bulk order for customs clearance and retail documentation.
Q: Can we specify different battery capacities or cell brands for our regional market?
A: Yes. The down-tube battery housing accommodates standard 36V and 48V configurations using tier-one cylindrical cells including Samsung, LG, and Panasonic. Alternative cell selections can be integrated during the ODM sample phase to meet local cost targets or warranty requirements.
Q: What is the minimum order quantity (MOQ) for custom frame colors and private-label branding?
A: The MOQ for custom Pantone powder coating and laser-etched frame branding is 50 units per colorway. For complete frame geometry modifications or custom mold development, the MOQ starts at 300 units.
Q: How are warranty claims and spare parts handled for bulk buyers?
A: We supply a standard 2-percent critical spare parts allocation (including motors, controllers, displays, and chargers) free of charge with every container shipment. Structural frames carry a 3-year replacement warranty, while electronic components and batteries carry a 2-year functional warranty backed by serial-number tracking.
Q: What is the standard packaging method to prevent shipping damage during ocean transit?
A: Units are packed in 7-layer double-wall export cartons separated by high-density EPE molded foam inserts. Critical friction points such as fork dropouts, handlebars, and derailleur guards are reinforced with protective plastic sleeves and corrugated bracing to withstand multi-modal freight handling.
Q: How is the torque sensor calibrated to handle steep gradients and heavy loads?
A: The bottom bracket utilizes a dual-sided strain gauge spindle that measures left and right leg power output independently. Factory firmware calibration applies a linear amplification ratio up to 300% assistance under high pedal torque, ensuring smooth, immediate motor engagement without abrupt surges when starting on steep inclines with cargo.
