How should a buyer compare battery and motor specifications across electric bike models?
Read voltage, capacity and power as different quantities
Voltage, ampere-hours and motor watts describe different parts of an electrical system and should not be compared as though they were one score. NIST identifies the volt as the SI unit of electric potential difference, the ampere as the unit of electric current and the watt as the unit of power. A buyer should record every value with its unit and compare complete systems, including the controller and intended operating limits, rather than choosing from one headline number.
Use catalogue differences to frame questions
The approved catalogue illustrates why model-level comparison matters. EB-001 lists a 36 V 250 W motor with a 36 V 6 Ah battery, EB-004 lists a 36 V 350 W motor with a 36 V 8 Ah battery, and EFB-010 lists a 48 V 500 W motor with a 48 V 10 Ah battery. These are confirmed reference specifications, not a promise that any electrical system can be substituted into another frame or approved for every market.
Treat range figures as configuration-specific statements
The catalogue distinguishes throttle range from pedal-assist range on detailed models and uses approximate wording for several figures. Range can be affected by the confirmed configuration and operating conditions, so it should remain tied to the named model and stated mode. For procurement, ask how the proposed battery, controller, motor, wheel and assistance settings relate to the quoted figure, and avoid republishing one model's range as a category-wide result.
Confirm system, market and documentation together
Electrical selection is also a market and documentation decision. ISO/TS 4210-10 includes power-management systems, electrical circuits and chargers for two-wheeled electrically power-assisted cycles within its scope and voltage boundary. A project brief should therefore identify the destination requirements, reference model, proposed electrical system, charger, display, intended use and required evidence before price or production timing is finalized.
