Product Overview
This mid-tail electric cargo bike features an 1,850 mm wheelbase and a 180 kg gross vehicle weight rating (GVWR). Designed for last-mile delivery operators, commercial fleet managers, and OEM brands, it offers the payload stability of a full-size cargo bike within the footprint of a standard urban utility e-bike.
The frame is fabricated from cold-drawn 6061-T6 aluminum tubing with automated TIG weld beads and CNC-machined forged dropouts. The asymmetric wheel design-combining a 24-inch front wheel for roll-over efficiency with a 20-inch rear wheel-lowers the rear cargo platform by 75 mm compared to dual 26-inch configurations, significantly reducing cargo center of gravity under full load.
Key OEM / ODM Manufacturing Specifications
• Frame Material: 6061-T6 Heat-Treated Aluminum Alloy (T4/T6 Thermal Treatment Cycle)
• Maximum Payload Capacity: 180 kg total (Rider: 100 kg / Rear Rack: 60 kg / Front Rack: 20 kg)
• Wheelbase Length: 1,850 mm (Total Overall Length: 1,980 mm)
• Bare Frame Weight: 4.8 kg (Total Bike Dry Weight: 31.5 kg excluding battery)
• Compliance Standards: EN 15194:2017, ISO 4210-2, UL 2849, ANSI/CAN/UL 2271
Key Features
Torsional Frame Rigidity: Reinforced chainstay bridge and internal gussets at the bottom bracket junction suppress lateral frame flex when carrying up to 60 kg on the rear platform at 25 km/h.
Dual-Battery Parallel System: Dual battery docks integrated into the down-tube and seat-tube allow single (48V 14Ah / 672 Wh) or dual-pack operation (48V 28Ah / 1,344 Wh) with automated discharge switching.
4-Piston Heavy-Duty Braking: TEKTRO HD-E350 hydraulic disc brakes paired with 180 mm x 2.3 mm thick rotors and motor cut-off sensors, engineered for sustained braking performance under maximum GVWR.
Frame-Integrated Structural Rear Rack: MIK and Yepp Maxi compatible mounting points welded directly to the main frame, eliminating bolted joint fatigue under dynamic cargo loads.
Torque-Sensing Powertrain: 1,000 Hz sampling rate bottom bracket torque sensor provides instantaneous motor response proportional to rider input, extending chain and cassette service life.
100 kg Rated Center Stand: Dual-leg aluminum center stand with broad footplates, providing static stability on uneven street surfaces during cargo loading.

Applications
Last-Mile Courier & Delivery Fleets
The 1,850 mm total length permits transit through standard urban bike lanes and pedestrian zones. The 20-inch rear wheel platform lowers the cargo surface height to 620 mm from the ground, mitigating tipping risks during quick cornering with insulated delivery boxes or parcel crates.
Commercial Utility & Rental Platforms
Featuring standardized components (Shimano gearing, Tektro hydraulics, standard 21700 cell formats), this platform allows fleet operators to source replacement wear items locally across North America and Europe, keeping vehicle downtime below 2%.
Family & Utility Commuting (White-Label Brands)
Accommodates up to two child safety seats or a single child seat combined with a 35L pannier bag. The low step-through frame geometry (standover height: 450 mm) supports rider heights from 155 cm to 190 cm without seatpost or handlebar adjustment tools.
