Pedal assist is a feature found on many electric bikes that provides additional power to the rider through an electric motor.

The motor is triggered by the rider’s pedaling and provides electric assistance based on the rider’s effort. In other words, the harder the rider pedals, the more assistance the motor provides.

This allows the rider to tackle hills and headwinds with ease, or simply cruise along with less effort. Pedal assist systems can be adjusted to provide different levels of assistance, allowing the rider to choose the right level of support for the task at hand. 

Overall, pedal assist is a convenient and effective way to enhance the electric bike riding experience and make it more enjoyable.

How Does Pedal Assist Work on Electric Bike?

Pedal assist on an electric bike works by using sensors to detect the rider’s pedaling effort. When the rider starts pedaling, the sensors send a signal to the bike’s electric motor, which then provides additional power to the pedals.

The motor then amplifies the rider’s pedaling effort so it seems like your legs are exerting more effort than they actually are, so the harder the rider pedals, the more power the motor provides. Most pedal assist systems use a torque sensor to measure the rider’s pedaling effort.

The torque sensor detects the force applied to the pedals and sends a corresponding signal to the motor. The motor then adjusts its output accordingly, providing more or less assistance based on the rider’s input.

In addition to the torque sensor, some pedal assist systems also use a cadence sensor to detect the speed at which the rider is pedaling. This information is used to fine-tune the assistance provided by the motor, making the system more responsive and intuitive to use.

Overall, pedal assist on an electric bike is a seamless and intuitive system that allows the rider to enjoy a more effortless riding experience.

By complementing the rider’s effort, pedal assist makes it easier to tackle hills, headwinds, and other challenging terrains, and allows the rider to enjoy the ride without getting exhausted.

What is a Throttle on an Electric Bike?

A throttle on an electric bike is a handlebar-mounted control that allows the rider to control the power output of the electric motor without having to pedal. This is different from pedal assist, where the motor provides assistance proportional to the rider’s own pedaling effort.

With a throttle, the rider can simply twist the grip to increase the power of the motor, providing an extra boost to help get up hills, navigate headwinds, or reach higher speeds.

Some electric bikes have both a throttle and pedal assist, allowing the rider to choose the best mode of operation for the task at hand.

Throttles are particularly useful for riders who want a more relaxed and effortless riding experience, or for those who want to cover long distances without getting tired.

However, it’s important to note that the use of a throttle may affect the battery life of the electric bike and could also reduce the overall range of the bike, as the motor is drawing power from the battery even when the rider isn’t pedaling.

Overall, a throttle is a convenient and effective way to control the power output of an electric bike, providing the rider with a higher level of control.
