Product Overview
The Step-Through Electric Commuter Bike is designed for high-frequency urban transit, commercial fleet integration, and municipal micro-mobility sharing programs. Featuring a low-standover aluminum frame geometry, it allows low-barrier rider mounting and dismounting across diverse urban user groups and daily operational attire.
Frame construction utilizes automated robotic TIG welding and precision CNC machining on the head tube. Manufacturing and quality control processes adhere to ISO9001 standards, with frame samples subjected to structural vibration and fatigue testing to ensure mechanical consistency across commercial production lots.
Key Features
Low-Step Frame Architecture: Formed from 6061 aluminum alloy to provide a low center of gravity and stable structural load-bearing capacity.
Integrated BMS Battery Protection: The Battery Management System provides continuous cell voltage monitoring, over-current protection, and thermal runaway mitigation during high-rate charging and discharging.
Torque-Sensing Pedal Assist: Utilizes combined cadence and force sensors to measure real-time crank pressure, providing proportional motor response aligned with pedaling effort.
Aramid-Reinforced Tires: Incorporates a high-density aramid fiber puncture-resistant belt beneath the tread to reduce inner tube damage from urban road hazards.
Hydraulic Disc Braking System: Features mineral-oil dual-piston calipers paired with electrical motor-cutoff sensors that interrupt power output instantly upon lever actuation.

Applications
Urban Shared Mobility Fleets:
Sealed cable routing, tamper-resistant frame battery locks, and low-maintenance hub configurations minimize routine field maintenance.
Corporate & Campus Transport:
Offers zero-emission internal mobility for personnel, security patrols, and facility management across large institutional properties.
Last-Mile Express Logistics:
Heavy-duty rear frame welding points accommodate commercial delivery boxes and panniers for urban courier operations.
Commercial Rental Operations:
Standardized step-through frames and durable exterior coatings accommodate high rider turnover in municipal and resort rental programs.
Available Configurations
Motor Drive Systems: Selection of 250W rear hub drives compliant with EU regulations or 500W high-torque mid-drive systems for hilly municipal topographies.
Power Source Options: Standard 36V downtube packs or high-density 48V configurations utilizing specified lithium-ion cell brands.
Transmission Interface: Choice of standard external derailleurs for simplified field servicing or sealed internal gear hubs for weather-exposed environments.
OEM/ODM Customization: Custom Pantone frame powder coating, private-label branding decals, laser-etched VIN serial numbering, and proprietary controller parameter flashing.
FAQ
Q: What is the Minimum Order Quantity (MOQ) for custom frame colors and private labeling?
A: Custom frame color powder coating requires an MOQ of 50 units per batch. Full private-label branding, custom carton artwork, and custom decal application start at 200 units per order batch.
Q: What safety compliance documentation is provided with bulk shipments?
A: Every production shipment includes complete test reports and certification documentation verifying EN15194 compliance for the European market and UL2849 electrical system certification for North America.
Q: How are complete electric bicycles packaged for international maritime shipping?
A: Units are packed 85% pre-assembled inside 7-layer heavy-duty corrugated export cartons, protected with custom-molded EPE foam block inserts to secure components and optimize container volume.
Q: What quality inspection procedures are conducted prior to factory dispatch?
A: Production runs undergo 100% automated electrical continuity checks, dynamic motor controller bench tests, hydraulic brake pressure leak inspections, and structural assembly audits.
