Description: The battery powers the motor
Key Specs:
Voltage (V) Speed
Capacity (Ah) Capacity
Energy (Wh) Distance
Types:
Lithium-Ion (Li-ion): Most common
Lead-Acid: Old Tech
Considerations:
Range: More Wh = more range.
Charge Time: How long to charge the battery.
Description: The motor drives the bike, assists with pedaling or propels full on.
Key Specs:
Power (W): Rated in watts, motors range from 250W to 1000W and beyond. More power = better performance, especially on hills.
Type: Where the motor is mounted.
Types:
Hub Motor: Mounted in the wheel hub (front or rear).
Front Hub Motor
Rear Hub Motor
Mid-Drive Motor
Considerations:
Efficiency: Mid-drive motors are generally more efficient and more torque.
Application: Hub motors are good for flat terrain; mid-drive motors are better for hills and off-road.
Controls the speed of the motor
Key Functions:
Regulates Power: Makes sure the motor gets the right amount of power.
Safety Features: Overheat protection and low-voltage cutoff.
Considerations:
Compatibility: Must be compatible with the battery and motor.
Features: Advanced controllers have regenerative braking and customizable power settings.
Description: Allows the rider to control the motor power directly, mounted on the handlebar.
Types:
Twist Throttle: Like a motorcycle throttle, twisted to control power.
Thumb Throttle: A lever pressed with the thumb to control power.
Considerations:
Control: Throttles give direct control over the motor, useful for acceleration and quick speed adjustments.
Description: Assists the motor when you pedal, with adjustable assistance levels.
Key Components:
Cadence Sensor: Checks to see if peddaling applies power
Torque Sensor: checks to see if you are peddaling then applies power consistent with the amout of peddal power
Considerations:
PAS is smoother than throttle-only systems.
Description: Mounted on the handlebars, shows real-time information about the ebike.
Key Info:
Speed: Current speed.
Battery Level: Remaining battery capacity.
Assistance Level: Current pedal assist level.
Distance: Trip distance and odometer.
Types:
Basic LCD: Shows basic info.
Advanced LCD/LED: Has navigation, diagnostics and customizable settings.
Description: Various sensors make the ebike function and safe.
Types:
Speed Sensor:
Torque Sensor:
Cadence Sensor:
Considerations:
Integration: Sensors should work with the controller and display for best performance.
**1. Brakes: Hydraulic or mechanical disc brakes are used for stopping power and reliability. **2. Wiring Harness: Connects all the electrical components. A good harness makes installation and maintenance easier. **3. Lights: Front and rear lights for visibility and safety.
Riding Style: Think about your typical riding conditions (e.g. flat vs hills) and choose components that fit your needs.
Budget: Higher end components are better and last longer but cost more.
