What Are the Main Parts of an Electric Bike?

The best e-bike can appear to be an ordinary bicycle; however, it is equipped with different special parts. This is a summary of the key parts:
Electric Motor
The most significant component of an e-bike is the motor. It provides extra power to assist your pedaling, making it easier to ride through tough terrain and uphill sections. In the Comparison of E-bike Motors, mid-drive motors like the one in the ENGWE MAPFOUR N1Pro often stand out for their superior performance and efficiency. This model is equipped with a 250W mid-drive motor, giving you power on demand—especially useful when tackling steep climbs.
Battery
The motor is powered by the battery, and the common batteries used in e-bikes are lithium-ion due to their lightweight and efficiency. The battery that is included with the ENGWE MAPFOUR N1 Pro is a removable 36V 10Ah lithium-ion battery, and it is possible to ride 100 km at pedal assist level one. The removable battery becomes handy since charging becomes easy and convenient.
Pedal Assist Sensor (PAS)
The PAS measures the rate you are pedaling and relays it to the motor to assist you to the same extent you are working. This provides a natural cycling experience. ENGWE MAPFOUR N1 Pro is designed with an 80N.M torque sensor, providing a comfortable driving experience, as it benefits from motor support as soon as you accelerate or go uphill.
Throttle (Accelerator)
There are e-bikes equipped with a throttle that lets you take control of the power of the motor. It is a good feature when you require additional help without pedaling. Although the ENGWE MAPFOUR N1 Pro has a power-assisted mode, other electric bikes might include a push-button.
Controller & Display
The display indicates details such as the speed, the battery level, and the power mode, and the controller regulates the battery power to the motor. ENGWE MAPFOUR N1 Pro has an LED color display. As a result, you have an easy-to-read screen with all the information about the necessary stuff.
Gears & Transmission
The majority of e-bikes have gears as a way of ensuring that you moderate your pedaling. The ENGWE MAPFOUR N1 Pro is equipped with the SHIMANO 7-speed transmission system that gives it the advantage of suitability to various riding surfaces, flat and hilly.
Brakes & Frame
Safety riding is difficult without brakes. The ENGWE MAPFOUR N1 Pro is installed with front as well as rear dependable brakes. It has a frame that is constructed using carbon fibre, giving it some strength without weighing it too much, and hence resulting in a durable and easy-handling bike.
Tires
Tires have a large impact on your ride comfort and stability. The ENGWE MAPFOUR N1 Pro is fitted with 700*42C spoke tires, which provide favorable controls and traction on diverse terrain, thus being ideal on city streets, as well as light off-road paths.
How Do Electric Bikes Work?

Electric bikes work by combining manual pedaling with motorized assistance. When you start pedaling, the pedal assist sensor (PAS) detects your effort and activates the motor to provide extra power. This helps you ride longer distances and navigate uphill terrain with ease.
The motor is powered by the battery, which supplies energy to both the motor and the display. The amount of assistance provided by the motor depends on the power mode you select. Some e-bikes allow you to use a throttle to control the motor’s speed, but the primary focus is usually on pedal assist.
The L20 Boost Fat E-bike features a 250W brushless mid-drive motor delivering up to 75 N·m of torque, which provides efficient and powerful assistance for climbing hills. Equipped with large 20 x 4.0 fat tires, it offers excellent traction and stability on diverse terrains. The bike supports inclines up to 10° and ensures a smooth ride with balanced weight distribution, making it ideal for both urban streets and light off-road conditions.
How to Choose the Right Electric Bike?
The type of e-bike you need depends on your intentions. These are a few considerations:
Urban Commuting vs. Mountain Trail vs. Folding Portable
- Commuter bike: In case you plan to use the bike as a means of commuting, select the model that is lightweight and easy to maneuver.
- Mountain Trail: To ride off-road, a bike with a stronger motor and hardy tires would be preferable.
- Folding: A folding bike can be useful when you have to squeeze your bike in small areas, or on buses or trains.
Battery Capacity and Range
The battery capacity also influences the extent of the ride using one charge. With a maximum extended ride of 100km, the ENGWE MAPFOUR N1 Pro is good enough to cover longer distances. In case you require extra range, you should find a bicycle that has a bigger battery.
Motor Type (Mid-mount vs. Hub)
E-bikes include mid-drive or hub motors. Mid-drive motors are much better in control and performance, particularly on hills. Hub motors are easier, yet they are comparably less expensive.
Regulatory Restrictions
The speed of e-bikes is also limited; e-bikes can only reach a certain speed, e.g., 25km/h in the EU. Before you buy, make sure to check the local laws as well, so that your bike is within the regulations of these laws.
How to Operate an Electric Bike?
Riding an e-bike is simple. This is how to start:
- Charge the Battery: You should have a fully charged battery before a ride. ENGWE MAPFOUR N1 Pro has a charging time of approx 5-6 hrs.
- Turn on the Bike: Press the power button on the display to turn the bike on.
- Select the Assist Mode: Select a pedal assist level that is appropriate. The throttle can be used when necessary, too.
- Start Pedaling: Start pedaling, and the motor will help you.
- Shift Gears: Use the gears to adjust your pedaling effort for different terrains.
- Brake: To slow down or stop, use the front and rear brakes.
