So, hop on and prepare to delve into the world of e-bike gears!
Types of e-bikes
Pedal-assist e-bikes
Pedal-assist e-bikes, also known as pedelecs, are the most common type of e-bike on the market. As the name suggests, these bikes provide assistance when pedaling. They are equipped with a motor that kicks in as soon as you start pedaling, providing an extra boost to your efforts. The level of assistance can usually be adjusted, allowing you to choose how much help you want from the motor. Pedal-assist e-bikes are a great option for those who still want to get some exercise while enjoying the benefits of electric assistance.
Throttle-controlled e-bikes
Throttle-controlled e-bikes, on the other hand, do not require you to pedal in order to receive assistance. These bikes are equipped with a throttle that allows you to control the speed and power of the motor with a simple twist of the handle. This makes throttle-controlled e-bikes more similar to motorcycles or scooters in terms of their operation. They are often favored by riders who don’t want to put in much physical effort or who may have mobility issues that make pedaling difficult.
Hybrid e-bikes
Hybrid e-bikes, as the name suggests, are a combination of pedal-assist and throttle-controlled e-bikes. They allow riders to switch between pedal-assist mode and throttle mode, giving them the flexibility to choose the level of assistance that best suits their needs in any given situation. Hybrid e-bikes offer the best of both worlds, providing the convenience and ease of use of throttle mode when needed, while still allowing for a traditional cycling experience with pedal-assist mode.
Gearing mechanisms in e-bikes
Hub gears
Hub gears, also known as internal hub gears, are a common type of gearing system used in e-bikes. In this system, the gears are enclosed within the hub of the rear wheel. Hub gears offer a range of gear ratios that can be changed easily, even when the bike is stationary. This makes them a popular choice for riders who prefer simplicity and low maintenance. Hub gears are also more resistant to damage from external factors such as dirt, making them suitable for various terrains and weather conditions.
Derailleur gears
Derailleur gears, also known as external gears, are the most common type of gearing system found in traditional bicycles. They consist of multiple gears on the rear wheel, with a derailleur mechanism that moves the chain between them. Derailleur gears offer a wide range of gear ratios, which makes them suitable for riders who enjoy tackling a variety of terrains. However, they require more frequent maintenance and adjustment compared to hub gears, as they are exposed to the elements and can be more susceptible to dirt and damage.
Internal geared hubs
Internal geared hubs are another type of gearing system used in e-bikes. Similar to hub gears, the gears in internal geared hubs are enclosed within the hub of the rear wheel. However, internal geared hubs offer a wider range of gear ratios compared to hub gears, providing more versatility for riders. They are also known for their durability and low maintenance requirements, making them a popular choice for e-bike riders who want a reliable and hassle-free gear system.
CVT systems
Continuously Variable Transmission (CVT) systems are a relatively new development in e-bike gearing. Unlike traditional gearing systems, which offer discrete gear ratios, CVT systems provide a smooth and seamless transition between gears. This means that you can adjust the gear ratio infinitely, allowing for a greater degree of customization and fine-tuning. CVT systems are often praised for their efficiency and ease of use, as there is no need to anticipate gear changes or worry about shifting at the wrong moment.

Differences between e-bike gears and regular bike gears
One major difference is that e-bike gears often have a wider gear range compared to regular bike gears. This is to accommodate the higher speeds and heavier weight of e-bikes. Additionally, e-bike gears are designed to handle the extra power and torque provided by the electric motor, which regular bike gears do not need to account for.
Understanding gear ratios
Gear ratios play a crucial role in determining how your e-bike performs in different riding conditions. Here’s a brief explanation of gear ratios in both e-bikes and regular bicycles.
Gear ratios in e-bikes
The gear ratio of an e-bike is the relationship between the number of teeth on the chainring (attached to the pedals) and the number of teeth on the rear cog (attached to the rear wheel). A higher gear ratio, such as 3:1, means that each revolution of the pedals results in more revolutions of the rear wheel, providing a higher speed. Conversely, a lower gear ratio, such as 1:3, allows for more torque and easier pedaling up steep inclines.
Gear ratios in regular bicycles
Regular bicycles also have gear ratios that determine the relationship between the front chainring and rear cog. However, the gear ratios in regular bicycles are usually higher than those in e-bikes, as they rely solely on human power. The gear ratios in regular bicycles are typically optimized for efficient pedaling and maximizing speed on flat or rolling terrain, rather than accommodating the extra power of an electric motor.
