Product Overview
This 28-inch electric commuter bike is engineered for OEM/ODM brand owners, fleet operators, and regional distributors targeting European and North American urban mobility markets. Built on a 6061 aluminum alloy frame, it integrates a removable 48V 15Ah lithium-ion battery pack with a 250W/500W brushless rear hub motor.
The vehicle structure complies with EN 15194:2017 standards for the European Union and UL 2849 safety certification requirements for North America. Standardized component interfaces (Shimano drivetrain, Tektro hydraulic disc brakes) allow regional distributors to reduce local spare parts inventory and simplify technical servicing.
Key Features
Frame Architecture & Cable Routing: Heat-treated 6061-T6 aluminum frame built with robot-welded joints. Hydroformed down tube secures internal routing for brake lines and electrical harnesses against moisture and physical damage.
Lockable Battery Integration: Down-tube embedded 48V 15Ah battery with key-lock retention mechanism. Removable design allows off-bike charging, bulk battery swapping for commercial fleets, and quick replacement during scheduled maintenance.
Power & Drivetrain Assembly: Rear hub brushless motor paired with a 12-signal cadence sensor and sine-wave controller. Delivers consistent torque output up to 45 Nm without cogging under steep urban grade starts.
Braking System: Front and rear Tektro hydraulic disc brakes with 180mm rotors and integrated motor power cut-off sensors, terminating motor assistance within 0.1 seconds of lever engagement.
Component Interchangeability: Standard ISO mounting points for fenders, rear pannier racks (up to 25 kg payload capacity), and front lighting fixtures, enabling rapid SKU customization at distribution warehouses.
