Electric Bikes: What Are They & How Do They Work?

Electric Bike

What is an electric bike?

Essentially, an electric bike is very much like a regular bike. However, an electric bike contains a few extra components that work together to enable the bike to function. The most common type of electric bike uses pedal assist, which means the motor is only activated when the pedals are already in motion. This enables the user to still workout while also having an added boost to make the journey easier.

What are the main components?

As mentioned, an electric bike relies on specific components to work together for it to operate. There are 3 main components in an electric bike:

  1. The motor

The motor can be placed in various parts of an electric bike, with each placement offering its own benefits. Placements may include:

  • Front hub
  • Rear hub
  • Mid-drive motor

The main function of the motor is to control torque. To achieve high torque, an advanced electric motor is required. With more torque, there is an increase in power gained from the bike.

  1. The battery

Much like the motor, the battery on an electric bike can be placed in various places dependent on the frame type and size. There are numerous battery makes, models and types which means that the length of charge is dependent on those 3 aspects. However, an average charging time is 5-6 hours.

  1. The sensor

The sensor on an electric bike is the most important component. Electric bikes contain one of two types of sensor:

  • Speed sensor
  • Torque sensor

The speed sensor instantly engages the motor once pedalling begins which gives users ride assistance. While a torque sensor is slightly smarter. This type of sensor responds with just a small amount of assistance to match the riders speed when moving. A torque sensor is more responsive and helps with speed and manoeuvres.

How do the components work together?

All the components in an electric bike must work together for the bike to work. The battery, motor and display combination provide all the assistance required in a smooth ride. The battery provides power for the motor which then provides power for the drivetrain to give you all the assistance when riding up hills and for longer rides. The display allows you to control how much assistance is provided and what power is sent from the motor to the drivetrain.

Usage

Most electric bikes have the pedal assist; therefore, users need to pedal for the electric assist to work. Once you are pedalling you can use the display on the electric bike to turn on the power assist. Users can adjust the assistance level choice with the plus and minus buttons the display.

Charging

To charge your electric you will just need to plug it into any wall outlet. Batteries can take from 2 to 8 hours to charge dependent on the make of the battery. Most electric bikes will last up to 1000 charge cycles.
