Electrify Your Commute: How to Pick the Best City e-Bike

The electric bike has existed since the end of the 19th century, but it remained in the shadow of motor vehicles for a long time. It was not until the advent of technologies, notably thanks to Yamaha in the 1990s, that the e-bike began to gain popularity. The revolution came in 2003 with the arrival of lithium-ion batteries, which are lighter and more durable than older lead models. Brands like Bosch have since contributed to its development.

Today, the e-bike is encouraged by cities and governments to reduce traffic and promote more ecological and cost-effective mobility. With the diversity of models and brands, it is essential to understand your needs to choose your electric bike. Motorization, battery, autonomy: several criteria must be considered to make the right choice.

What Type of Electric Bike to Choose?

When looking to equip yourself with an electric bike, the first criterion to consider is the intended use. Depending on your needs and habits, several types of electric bikes are available to you: city bikes, MTBs, road bikes, or gravel bikes. Here is an overview to help you choose the model that best suits you.

The Electric City Bike

The electric city bike is designed to meet the needs of urban dwellers. With its upright riding position, it offers ideal comfort for daily commutes, whether for going to work or running errands. Low-step frames make it easy to mount and dismount, and features such as racks, fenders, and integrated lighting make it a very practical choice. Some variants, such as cargo bikes or longtails, allow you to carry heavy loads or children, ideal for families or professionals who need a reliable means of transportation in the city.

How to Choose the Battery for Your Electric Bike?

There are also different types of electric bike batteries. Of course, with several types of motors, there could not be just one type of battery and mounting for e-bikes. The battery of an electric bike is expressed in watt-hours (Wh). Its value is generally between 400 and 800 Wh. Since 2018, the trend has been to integrate the battery into the frame. This makes your electric bike more discreet and harder to distinguish from a regular bike. However, make sure the battery of your bike is removable, as an electric bike battery has a lifespan and will need to be changed and recycled one day. Other more classic types of batteries are attached to the frame at the bottom tube, directly behind the seat tube, or on the rear rack at the back of the bike. Prefer a battery positioned in the center of the bike rather than at one end to avoid poor weight distribution of the electric bike.

Battery Position (frame, rack, or integrated)

Frame Battery

Offers excellent balance and better stability, ideal for climbs and rough terrain. Easy to remove for charging.

Rack Battery

Frees up space on the frame and allows for additional accessories. Perfect for urban use with a practical style.

Integrated Battery

Discreet and stylish, it is perfectly protected against shocks and weather. Ideal for a modern and sleek design.

What Criteria to Consider When Choosing the Battery for Your Electric Bike? (V, Ah...)

Voltage (V)

The voltage, expressed in volts (V), determines the power of the electrical system. The higher the voltage, the more energy the bike can provide for accelerations or difficult climbs. If we were to compare it to a gasoline engine, it would be the pressure with which the fuel is injected.

Capacity (Ah)

The ampere-hour (Ah) indicates the capacity of the battery, i.e., the amount of electrical energy a battery can supply in one hour. To compare it to a fluid, it would be the flow rate, how many liters per hour pass through a pipe.

Energy Quantity (Wh)

Measured in watt-hours (Wh), it is the product of voltage (V) and capacity (Ah). It reflects the total autonomy of the battery. Compared to a fluid, it would be the number of liters in a fuel tank.

Charging Time

The charging time for an e-bike battery is not very fast, ranging from 3 to 6 hours depending on the size of your battery and the type of charger used. Fast chargers can reduce this time, but slow charging extends the battery life.

Number of Cycles

Each battery wears out over time. Modern batteries have between 1,000 and 2,000 full charge cycles before losing about 20% of their original capacity. No need to worry, though, as Bosch claims their batteries have a lifespan of about 30,000 km.

What Size Battery to Choose for Your Electric Bike?

The size of the battery determines the autonomy of your electric bike. It is generally expressed in watt-hours (Wh), a unit that reflects energy capacity. For urban use or short trips, a battery of 300 to 400 Wh is usually sufficient. For longer trips or hilly terrain, opt for a battery of 500 Wh or more. Don't forget to consider your weight, the level of assistance used, and the conditions of the route, as these factors directly influence consumption. A suitable battery ensures a smooth and uninterrupted experience.

As explained above, when choosing a battery for your electric bike (e-bike), the main criterion to consider for autonomy is the capacity in Wh. This capacity can be compared to the size of a fuel tank in a thermal car. However, just like a gasoline car, it is better to have a 30-liter tank with a consumption of 6 L/100 km than a 40-liter tank with a consumption of 10 L/100 km. With an electric bike, it's the same: some brands like Bosch offer very efficient motors, while others are less optimized. Moreover, autonomy varies depending on the mode of assistance chosen (usually four modes).

To give you an idea, here is a simplified estimate of autonomy based on battery capacity and the mode of assistance used:

400 Wh

A 400 Wh battery will allow you to travel about 40 km in turbo mode and up to 80 km in eco mode.

500 Wh

A 500 Wh battery will allow you to travel between 50 km in turbo mode and nearly 100 km in eco mode.

600 Wh

A 600 Wh battery will provide about 60 km in turbo mode and up to 120 km in eco mode.

750 Wh

A 750 Wh battery will ensure at least 75 km in turbo mode and up to 150 km in eco mode.

How to Choose the Motor for Your Electric Bike?

Now that you have an idea of what exists in terms of electric bike batteries, you might be wondering which motor to choose? Here is a presentation of the main points to consider regarding the motor when choosing your electric bike.

Motor Position (central or rear wheel?)

Front Wheel Motor

Ideal for entry-level bikes and short trips. Quick start, perfect for the city, but can be heavy and less suitable for long distances. It is becoming less common.

Rear Wheel Motor

Provides better propulsion. However, the weight distribution with a rear battery can be problematic, especially with panniers. Maintenance (e.g., flat tires) is also more complex.

Central Motor

The most efficient, used on MTBs and electric road bikes. Intelligent assistance management for better autonomy and optimized power.

What Technical Criteria to Consider When Choosing the Motor for Your Electric Bike? (power, torque...)

Power

The power of an e-bike motor, expressed in watts (W), determines its assistance capacity. The higher the power, the more the bike could go fast, although European legislation limits the speed of an e-bike to 25 km/h and the nominal power to 250 W. Indeed, a more powerful motor would classify the bike as a moped, requiring registration. Note that this power is nominal (maintained for 30 minutes without degradation), while the maximum power can exceed 250W.

Torque

Unlike power, torque is not subject to regulation. It is measured in newton-meters (Nm) and reflects the motor's force at low speeds. Simply put, the higher the torque, the faster you reach maximum speed. A high torque (50 to 85 Nm) is ideal for steep climbs or carrying heavy loads...

Assistance Factor

The assistance factor indicates the percentage of your own power that the motor adds to help you. For example, an assistance factor of up to 340% means that if you provide 100 watts while pedaling, the motor adds 340 watts.

Pedaling or Torque Sensor?

E-bike motors can be activated based on two types of sensors: - Rotation Sensor: The motor activates as soon as you pedal, without considering the effort. Cheaper but less precise. - Torque Sensor: Adjusts the assistance based on the applied force, offering a more natural and responsive feel, ideal for hilly terrain.

How to Choose Your Electric Bike: Motor FAQ

The best position depends on the usage. A central motor is ideal for optimal weight distribution and smooth assistance, perfect for MTBs or high-end bikes. The rear wheel motor offers natural propulsion for sporty or versatile rides. The front wheel motor, although less common, is suitable for entry-level bikes for urban or short trips.


A nominal power of 250 W is standard for e-bikes in Europe. For torque, a motor of 50 Nm is sufficient for urban use, while a torque between 70 and 85 Nm is preferable for steep climbs, rough terrain, or carrying heavy loads.


The assistance factor indicates the percentage of your own power that the motor adds to help you. For example, an assistance factor of 340% means that if you provide 100 watts while pedaling, the motor adds 340 watts. This criterion is essential for evaluating performance and choosing a motor suited to your needs, whether for sport or energy savings.


Motors with a rotation sensor activate as soon as you pedal, providing immediate but less natural assistance, ideal for economical urban use. Torque sensors adjust the assistance based on the applied force, offering a more responsive and natural feel, suitable for hilly terrain and sporty use.


Bosch offers several models tailored to different needs: the Active Line for urban commuting, the Cargo Line for carrying heavy loads, the Performance Line for sporty rides, and the Performance Line CX for e-MTB enthusiasts. Each motor offers optimal assistance levels and torque ranging up to 85 Nm.


How to Choose the Groupset for Your Electric Bike?

Another aspect not to be neglected is the braking and transmission components fitted to your future bike!

Regarding transmission, on an e-bike, robustness is more important than gear range because the motor is there to "smooth out" the difficulty. Urban cyclists will tend to prefer hub gears (e.g., Shimano Nexus) that require no maintenance and have only 7 or 8 gears. On the other hand, those who will use the bike on steep terrain will prefer a wider gear range (up to 12 gears) that only a derailleur can offer. Generally, the latter will also be equipped with a suspension fork for more versatile use, known as a "hybrid bike."

Braking is also important, as an electric bike is heavier and generally faster than a conventional bike, making it harder to slow down. This is why many electric bikes are equipped with disc brakes, which are the most efficient braking system today.

The Display (the application of your e-bike)

They are all different but generally indicate the same information: real-time speed, distance traveled, selected motor assistance, and battery level. It is an element that can be changed on your electric bike if you do not like it or if you want a more advanced model. Some brands offer the option of a removable model to limit degradation of bikes left overnight in the city center. With all this new information, you will be able to make a decision on the bike best suited to your practice.
