- Power needs vs. battery capacity: Higher wattage provides stronger assistance but demands a matching battery and controller. Consider your terrain and typical ride length.
- Drive type: Hub motor kits are simpler to install; mid-drive kits typically offer better torque and efficiency on hilly routes but may require more installation effort.
- Controls and display: LCD displays help monitor speed, battery, and fault codes. Choose one that fits your preference for pedal-assist levels and cruise control.
- Brakes and compatibility: Check compatibility with brakes (disc vs. V-brake) and ensure the kit won’t interfere with frame components or chainring geometry.
