How do electric bikes work?

Fast becoming a popular transport choice across the nation, e-bikes are designed to make the riding part of cycling a bike virtually effortless – providing a relaxing journey and enjoyable through the assistance of an electric motor. But how do electric bikes work? First, it would be beneficial to explain exactly what an e-bike is:

What is an e-bike?

An e-bike, or electric bike, is a pedal bicycle which is fitted with a battery and electric motor. As you pedal, the motor of the bike will kick in and alleviate some of the strain of the cycling for the rider. As soon as you stop pedalling or brake, the motor will automatically switch off.

Also, as you reach the maximum speed of the e-bike (which is typically around 15mph), the bike will cut out – meaning the hard work is then transferred back to the rider. If you want to go faster than the maximum speed then you can, but the motor will not assist you. However, with the B4 E-Cruizer, you can alternate between the eight various intensities which are designed to allow for variation in terrain.

How do electric bikes work?

There are three main components of electric bikes:

  • Motor – this can be located in various places on the bike, from the hub or rear hub to the mid-drive. The main purpose of the motor of an e-bike is to control torque – and the more torque you have, the more power you’ll be able to derive from your bike.
  • Sensor – there are two types of sensors: a torque sensor – which responds with assistance to match your speed while moving; or a speed sensor – which instantly engages the motor as you begin pedalling. A torque sensor is the smarter of the two and assists with responding effectively to manoeuvres and speed changes.
  • Battery – similar to the motor, the battery can be found in various places across the bike, which can be dependent on the style, frame and type of bike. Each type of electric bike has a different battery charging time, which is typically around 5-6 hours. An B4 E-Cruizer takes 6 hours to charge from empty.

The key to a successful bike is that the components of the electric bike work together simultaneously – ideally, the battery, motor and sensor will combine to create a smooth and enjoyable ride. The battery will provide power to the drivetrain meaning you’ll be able to successfully tackle hills, long rides and difficult terrain as you travel. Learn more about how the B4 E-Cruizer works now.

Do electric bikes charge themselves?

The technology is available in some e-bikes to recharge as you’re riding. This is typically when the rider is braking – in which case, the battery range can be extended by 5-10% if this feature is available. As you’re a braking, a sensor triggers the motor to go into ‘reverse mode’ – meaning it uses the energy of the bike’s forward motion to charge the e-bike. Known as regenerative braking, this mechanism is more common in vehicles than in electric bikes. For more information on our B4 E-Cruizer bikes, find out how to charge the battery from our FAQ section.
