Longtail Cargo Bike

Heavy-duty commercial longtail cargo platform engineered for high-payload urban logistics, fleet operations, and utility transport. Built on a reinforced 6061-T6 aluminum or chromoly steel extended chassis, this platform supports a gross vehicle weight rating (GVWR) of up to 200 kg while preserving standard bicycle wheelbase maneuverability. Integrated with mid-drive torque-sensing motor systems and dual-battery configurations, it provides continuous power output for commercial duty cycles. Designed for B2B fleet deployment and brand customization.

Description

Heavy-duty commercial longtail cargo platform engineered for high-payload urban logistics, fleet operations, and utility transport. Built on a reinforced 6061-T6 aluminum or chromoly steel extended chassis, this platform supports a gross vehicle weight rating (GVWR) of up to 200 kg while preserving standard bicycle wheelbase maneuverability. Integrated with mid-drive torque-sensing motor systems and dual-battery configurations, it provides continuous power output for commercial duty cycles. Designed for B2B fleet deployment and brand customization.

 

Key Features

01/

Extended Rear Deck Architecture: 850mm structural rear rack integrated directly into the main frame triangle, eliminating flex under eccentric loads and supporting modular accessory mounts (flight decks, child seats, and insulated delivery boxes).

02/

Mid-Drive Torque-Sensing Power Unit: 250W-750W nominal motor delivering 85Nm-110Nm of torque, dynamically matching rider input to maintain cadence and traction under full payload on steep inclines.

03/

Dual-Battery Power System: Parallel 48V configuration supporting up to 1,440Wh capacity using automotive-grade lithium-ion cells, engineered for uninterrupted multi-shift commercial operation.

04/

Hydraulic Four-Piston Disc Brakes: 2.3mm thick dual-piston rotors with 180mm front and 203mm rear diameters, calibrated to halt a fully loaded 200kg vehicle within standard braking distances.

05/

Step-Through Low Center of Gravity: Slotted geometry keeping the cargo plane 600mm off the ground, reducing tipping moments during stop-and-start urban delivery routes.

Applications

Last-Mile Parcel Delivery:

High-density urban distribution routes replacing light commercial vans, bypassing traffic congestion, and eliminating parking infraction overheads.

Food & Grocery Logistics:

Temperature-controlled insulated cargo box integration for hot food or cold grocery transport in metropolitan zones.

 

Municipal Maintenance & Facility Operations:

Utility transport for tools, safety gear, and maintenance equipment across large industrial campuses, parks, and pedestrian zones.

Micro-Mobility Fleet Operations:

Scalable hardware for dockless or station-based urban cargo bike sharing networks.

 

Manufacturing & Quality Control

 

Production utilizes automated robotic MIG and TIG welding cells for frame joint consistency, followed by T6 heat-treatment furnaces to restore aluminum structural integrity post-welding. Every frame undergoes CNC alignment verification and 100,000-cycle dynamic drop testing on ISO 4210-compliant test rigs. Electrical assemblies undergo 48-hour burn-in testing under maximum load conditions prior to final assembly. Salt-spray corrosion testing (ASTM B117) ensures frame coatings withstand 721 hours without galvanic degradation in coastal environments.

 

OEM / ODM Customization

Structural Modifications:

Custom rear deck length, specialized mounting hole patterns for proprietary logistics boxes, and integrated low-rider front rack brackets.

Powertrain Integration:

Firmware flashing for regional speed limiting (25 km/h EU / 32 km/h US), throttle integration options, and CAN-bus protocol adjustments for fleet telemetry tracking.

Branding & Finish:

Pantone-matched powder coating, laser-etched seatstays, custom headbadge tooling, and private-label user display interfaces.

 

Packaging

 

Export-grade packaging utilizes a 7-layer reinforced corrugated master carton with high-density EPE foam blocking securing critical stress points (head tube, dropouts, and rear rack extremities). Each unit is pre-assembled to 85%, requiring only handlebar alignment, pedal installation, and front wheel mounting. Standard pallet configuration: 4 units per standard wooden pallet (heat-treated ISPM 15 compliant), stacked two tiers high for optimized 40-foot container utilization (approx. 132 units per 40HQ).

FAQ

 

Q: What is the minimum order quantity (MOQ) for custom OEM configurations?

A: Standard catalog models have an MOQ of 10 units per color/specification. Custom frame geometry modifications or proprietary paint pantones require an MOQ of 50 units.

Q: What documentation is provided for regulatory import clearance?

A: Shipments include commercial invoices, packing lists, Bills of Lading, Certificate of Origin (Form E/CO), EN 15194 test reports issued by accredited labs (TÜV/SGS), and individual battery MSDS documentation.

Q: How is battery safety verified during production?

A: Every battery pack utilizes cells from Tier-1 manufacturers (Samsung, LG, Panasonic) paired with a smart Battery Management System (BMS) that monitors cell-level voltage, temperature, and overcurrent protection. Packs undergo vibration testing and thermal chamber cycling.

Q: What is the lead time for standard bulk orders?

A: Production lead time is 35 to 45 days upon receipt of deposit and technical sign-off for orders under 500 units. Peak season scheduling is confirmed during contract negotiation.

Q: Can the drivetrain be configured for hilly terrain with heavy loads?

A: Yes. The platform pairs high-torque mid-drive motors (up to 110Nm) with wide-range internal gear hubs (such as Enviolo Cargo) or derailleur gearing, maintaining a 20% climbing grade capability at a 180kg gross load.

Q: What is the warranty coverage for commercial fleet deployment?

A: The structural frame carries a 5-year replacement warranty against manufacturing defects. Motors, controllers, and battery packs are covered by a 2-year commercial-use warranty. Replacement parts are dispatched from regional warehouse stock.
