What Is The Difference Between Pedal-assist And Throttle-controlled Electric Bikes?

So you’ve heard about electric bikes and you’re curious to know more. Well, let’s start with the basics. When it comes to electric bikes, there are two main types: pedal-assist and throttle-controlled. The main difference between the two lies in how they provide assistance to the rider. With pedal-assist electric bikes, also known as pedelecs, the motor kicks in only when you pedal, giving you an extra boost. On the other hand, throttle-controlled electric bikes allow you to control the speed with a twist of a throttle, similar to how motorcycles operate. Both types have their unique advantages, so let’s take a closer look at each to help you decide which one suits your needs best.

Definition of Pedal-assist Electric Bikes


Pedal-assist electric bikes, also known as electric bicycles, are a type of bicycle equipped with an electric motor that provides assistance to the rider’s pedaling. These bikes are designed to augment the rider’s pedaling efforts and make cycling easier, especially when climbing hills or traveling long distances. The electric motor is activated by the rider’s pedaling motion and provides additional power to the bike’s drivetrain, propelling it forward.

How It Works

Pedal-assist electric bikes work by sensing the rider’s pedaling motion and delivering power from the electric motor accordingly. When the rider starts pedaling, sensors in the bike’s drivetrain detect the force and speed at which the pedals are being turned. Based on this input, the electric motor kicks in and provides assistance, amplifying the rider’s pedaling power. The level of assistance can typically be adjusted using a control panel or display on the handlebars, allowing the rider to choose how much electric assistance they desire.

Pedal-assist electric bikes are designed to provide a natural cycling experience, with the electric motor only assisting the rider’s effort rather than completely propelling the bike on its own. This means that the bike still requires the rider to pedal, but the added electric power makes pedaling easier and less strenuous. The electric motor automatically turns off once the rider stops pedaling or when the bike reaches a certain speed, ensuring that the assistance is only provided when needed.

Definition of Throttle-controlled Electric Bikes


Throttle-controlled electric bikes, also known as e-bikes or electric scooters, are a type of electric-powered transportation device that can be operated using a throttle. Unlike pedal-assist electric bikes, which require the rider to pedal in order to activate the electric motor, throttle-controlled e-bikes can be propelled solely by using the throttle, without any pedaling required. These bikes are often designed to resemble traditional bicycles, with the addition of a throttle mechanism.

How It Works

Throttle-controlled electric bikes work by utilizing a throttle mechanism, similar to those found on motorcycles or scooters. The throttle is typically located on the handlebars, and when the rider twists or pushes the throttle, it activates the electric motor, propelling the bike forward. Unlike pedal-assist bikes, throttle-controlled e-bikes do not require any pedaling from the rider to initiate the motor’s power delivery. The rider has the ability to control the speed of the bike solely through the throttle mechanism.
