What is a throttle, and how does it affect speed?
A throttle is a mechanism that controls the speed of an e-bike’s motor without the need to pedal. It is typically located on the handlebars and comes in two types: twist and thumb. Using a throttle increases speed and provides more control over the motor. However, it can drain the battery quickly and may not be allowed in some areas due to safety concerns.
What is pedal assist, and how does it affect speed?
Pedal assist is another mechanism that assists the rider in pedaling and provides power to the motor. It works by sensing the rider’s pedaling and adding a variable level of assistance. Pedal assist affects speed by increasing the motor’s overall power output, enabling the rider to reach faster speeds. Additionally, pedal assist conserves battery life, as it only provides power when the rider is pedaling.
Can modifications be made to increase an e-bike’s speed?
Yes, modifications can be made to increase an e-bike’s speed. Some improvements include changing the gear ratio, upgrading the motor or battery, and replacing the controller.
