Start with the operating requirement
Do not begin with the largest motor in the catalog. Begin with the route: rider and cargo weight, gradients, stop frequency, expected speed, daily distance and charging window. These inputs define the useful power band and the battery needed to support it.
Typical platform positioning
| Power band | Typical positioning | Buyer priority |
|---|---|---|
| 350W | Compact city and entry retail | Cost, low-speed efficiency, simple service |
| 500–800W | Urban commuting and delivery | Balanced payload, speed and range |
| 1000W+ | Heavy-duty, hills and premium retail | Torque, higher speed target, stronger chassis |
Motor power changes the battery decision
Higher output increases peak current demand. The battery and controller must support that demand without excessive voltage drop or heat. When comparing quotations, ask for the battery chemistry, voltage, capacity, controller current and tested range conditions.
Questions to send the supplier
- What payload and gradient were used in testing?
- What controller current is paired with the motor?
- At what average speed was the range measured?
- Can the speed be configured for the destination market?
- Which brake, tire and suspension options match the selected output?
A practical selection shortcut
Use 350W for compact cost-led city programs, 500–800W for balanced urban and delivery work, and 1000W+ when payload, hills or higher-output retail positioning justify the extra system cost. Final selection should always be confirmed on a sample.
