Electric Bike: The Future Of Cycling?

Electric bikes, also known as e-bikes, are bicycles with an integrated electric motor to assist propulsion. They are available in two broad categories: bikes that assist the rider's pedal-power (pedelecs) and bikes that add a throttle, integrating moped-style functionality. E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e. when and how the power from the motor is applied.

How do electric bikes work?

Electric bikes, or e-bikes, are bicycles with a built-in motor and battery to assist your pedalling. The motor is powered by a rechargeable battery mounted on the bike. E-bikes are typically classed according to the power that their electric motor can deliver and the control system.

There are two broad categories of e-bike: bikes that assist the rider's pedal-power (pedelecs) and bikes that add a throttle, integrating moped-style functionality. Both retain the ability to be pedalled by the rider and are therefore not electric motorcycles.

Pedelecs are legally classed as bicycles rather than low-powered motorcycles or mopeds. The most influential definition of pedelecs comes from the EU, which considers a bicycle to be a pedelec if the pedal-assist cuts out when the motor produces a maximum continuous rated power of not more than 250W.

The motor on an e-bike can be housed centrally on the bike (a mid-drive motor, powered through the cranks) or on the front or rear hub. A hub-based motor will push the wheel around directly, while an axle-mounted motor will work through the e-bike's chain and gears.

Different types of electric bikes

Electric bikes, also known as e-bikes, are available in a variety of styles, including cruiser, hybrid, and mountain. Each style is tailored to a particular terrain and type of ride. For example, cruisers are ideal for casual rides on pavement, while mountain bikes are designed for rugged trails.

E-bikes can also be categorised by their motors. There are three main types: front hub motors, which are located on the front tire and move the bicycle forward by spinning the tire; mid-drive motors, which power the bicycle drivetrain instead of the tire hub, creating a natural sensation; and rear hub motors, which are located on the back tire and move the bicycle forward by spinning the back tire.

In addition, there are three classes of e-bikes: Class 1 pedal-assist e-bikes, which provide assistance only when the rider is pedalling and are limited to a top speed of 20 mph; Class 2 e-bikes with a throttle; and Class 3 speed pedelecs.

How to ride an electric bike

An electric bike, or e-bike, is a bicycle with an integrated electric motor to assist propulsion. E-bikes can be split into two categories: bikes that assist the rider's pedal-power (pedelecs) and bikes that add a throttle, integrating moped-style functionality. Both types can be pedalled by the rider, so they are not electric motorcycles. E-bikes use rechargeable batteries and are typically motor-powered up to 25-32 km/h (16-20 mph).

To ride an e-bike, you will need to be able to ride a regular bike. You will need to be able to balance, steer and pedal. Once you have mastered these skills, you can start to think about riding an e-bike.

When riding an e-bike, you will need to be aware of the different power settings and how to use them. The power settings will either be a pedal-assist system or a power-on-demand system. With a pedal-assist system, the electric motor is regulated by pedalling. This means that the motor will only engage when you are pedalling and will cut out when you stop. With a power-on-demand system, you can add a throttle and use the motor without pedalling.

When riding an e-bike, it is important to be aware of your surroundings and use hand signals when turning or stopping. You should also make sure that you are visible to other road users, especially at night or in low-light conditions. Wear reflective clothing and use lights when riding in the dark.

It is also important to maintain your e-bike and keep it in good working order. This includes regularly checking the tyres, brakes and lights, as well as keeping the bike clean and free of debris. You should also make sure that the battery is charged and the motor is functioning properly.

Finally, when riding an e-bike, it is important to follow the rules of the road and be considerate of other road users. This includes obeying traffic laws, using designated bike lanes where available, and yielding to pedestrians and other vehicles when necessary.

Legality of electric bikes

Electric bikes, or e-bikes, are bicycles with an integrated electric motor to assist propulsion. E-bikes are classed according to the power that their electric motor can deliver and the control system. The classification of e-bikes varies across countries and local jurisdictions, with the main distinction being whether the e-bike's motor assists the rider using a pedal-assist system or by a power-on-demand one.

In the UK, electric bikes are legal for recreational use on private land and parks. For most electric bikes, you do not need a licence of any kind. However, if the bike has a motor rated more than 250W or an assisted speed of higher than 15.5mph, you will need a licence. These bikes are referred to as speed pedelecs or s-pedelecs and are subject to different regulations. Any electrically assisted vehicle that falls outside of the standard e-bike category must be registered, taxed, and requires a licence.

The EU directive (EN15194 standard) for motor vehicles considers a bicycle to be a pedelec if the pedal-assist cuts out when the motor produces a maximum continuous rated power of not more than 250W. The motor can produce more power for short periods, such as when the rider is struggling to get up a steep hill.

Electric bike motors

Electric bikes, or e-bikes, are bicycles with an integrated electric motor to assist propulsion. The electric motor is powered by a rechargeable battery and works in conjunction with the rider's pedalling to provide various levels of assistance. The motor's function is to convert electrical energy from the battery into mechanical energy, causing the wheels to rotate and propel the bike forward.

The type and placement of the motor significantly impact the performance of an e-bike, influencing factors like power output, handling characteristics, and overall efficiency. There are two main categories of electric bike motors: hub motors and mid-drive motors. Hub motors are simpler, more affordable, and require minimal maintenance. They are ideal for casual riders on flat terrain and those looking for a budget-friendly option. Mid-drive motors offer a more natural riding feel, excellent climbing ability, and a wider range of assistance levels.

Hub motors are typically found on the front or rear hub of the bike. They push the wheel around directly, providing an extra boost of power to the rider's pedalling. Front-hub motors are common on electric bikes designed for commuting, such as electric hybrids and electric folding bikes, as well as on cheaper models. Rear-hub motors are usually found on hybrids and some of the best electric road bikes.

Mid-drive motors, on the other hand, are powered through the cranks and work through the e-bike's chain and gears. They are often referred to as central or bottom-bracket motors. Mid-drive motors are found across all different types of electric bikes, but they are particularly well-suited for electric mountain bikes due to their weight being central and low, improving riding characteristics.
