The brain of the e-bike, controlling the flow of electricity from the battery to the motor based on user input (e.g., throttle, pedal-assist level). Usually integrated into the frame or attached near the motor or battery. Twist or thumb throttle. Allows the rider to control the motor's power manually, like a motorcycle. Not all e-bikes have throttles (common in pedal-assist only models). Measures if the rider is pedaling and activates the motor accordingly. Measures the force applied on the pedals to provide proportional assistance. Detects rider input and adjusts motor assistance, enabling a more natural cycling experience.
Provides real-time information such as battery level, speed, distance traveled, and pedal-assist mode. Mounted on the handlebars for easy visibility. Allows the rider to adjust settings, such as pedal-assist levels, or turn the system on and off. Sometimes integrated with the display or as separate buttons on the handlebars. Recharges the battery when depleted. Most e-bike chargers are designed to plug into a standard electrical outlet.
Connects the battery, motor, display, and controller. Often integrated or hidden within the bike frame for protection and aesthetics. E-bike frames are typically sturdier to handle the added weight of the motor and battery. E-bikes often come with disc brakes to provide extra stopping power due to the increased speed and weight. Includes the chain, gears, pedals, and cranks, working in conjunction with the motor for propulsion. In mid-drive motors, the chain and gears are crucial for transmitting motor power. These components work together to provide a seamless, enhanced cycling experience with electric assistance.
