How does an e-bike rear motor work?

A rear motor on an e-bike works by transferring the power of the electric motor directly to the rear axle of the bike. This is usually done through the use of a belt or chain drive. The motor is usually placed in a housing near the rear wheel hub. This drive mechanism has both advantages and disadvantages compared to other types of electric motors that can be used in e-bikes.

Advantages of e-bike rear motors

Since the motor is placed in the rear axle, it can balance the weight distribution of the bike and thereby enable better handling and control.
The space required in the bike frame for the battery and other components can be reduced because the motor is placed in the rear axle.
A rear engine may be able to produce higher horsepower, allowing for faster speeds and better acceleration.

Disadvantages of e-bike rear motors

A rear motor can make the bike heavier and more difficult to handle, especially if damage occurs to the motor or drive.
The motor and drivetrain in the rear of the bike can be more difficult to check and maintain.
A rear motor can typically be more expensive than other types of electric motors and maintenance and repairs can also be more expensive.

An e-bike rear motor can be a good choice for people who value balanced weight distribution and higher performance. However, the potential disadvantages, especially the higher cost and the difficulty of maintenance and repair, should be considered before making a decision.

Differences to other e-bike motors

The main difference between a rear motor e-bike and other types of e-bike motors is where the motor is positioned. A rear motor is mounted in the back of the bike, while other motors are placed in the middle of the bike (mid-motor) or in the hub of the front wheel (front hub motor).

An e-bike with a rear motor usually offers higher performance and a longer range than e-bikes with other motors. A rear motor also allows for better weight distribution and greater stability of the bike, as the weight of the motor and battery is not on the front of the bike.

Coaster brake on e-bikes: Useful or outdated?
Anyone who buys an e-bike will at some point face the question: with or without a coaster brake? While older generations of bicycles were almost exclusively equipped with coaster brakes, many modern e-bikes today rely on rim or disc brakes. But which is really better? And for whom is a coaster brake still a sensible option?
Goodbye car: How giving up your car protects the climate – and how it can be achieved with an e-bike
Commuting to work in the morning, a quick trip to the supermarket, and a weekend outing into the countryside – for many, the car is still the first choice. But anyone who seriously discusses climate protection today cannot avoid an uncomfortable truth: private car traffic is one of the biggest sources of CO₂. At the same time, the leverage here is particularly large – and, above all, tangible. Those who forego their car, or at least use it much less frequently, significantly reduce their personal carbon footprint. But how can this be implemented in everyday life?
Kettenblatt beim E-Bike: Wie die Größe das Fahrgefühl beeinflusst
Das Kettenblatt ist ein zentrales Bauteil am E-Bike, das oft unterschätzt wird.
