The Complete Guide to 45 km/h E-Bikes: Performance, Regulations, and Top Models for 2025

A 45 km/h e-bike, also known as an S-Pedelec, provides pedal assistance up to a speed of 45 km/h. Compared to standard pedelecs, which only operate up to 25 km/h and with a maximum of 250 watts, you get significantly more power here.

You benefit from these advantages:

• S-Pedelecs offer assistance up to 45 km/h and motor power up to 4000 watts.

• They are space-saving, eco-friendly, and offer a real time advantage in city traffic.

• Especially for commuters, sporty riders, or cargo transport, a 45 km/h e-bike can replace the car.

In 2023, sales of e-bikes exceeded those of classic bicycles for the first time. Even though S-Pedelecs still have a market share of less than one percent, their potential is growing due to new regulations and innovative 2025 models. Performance and legal requirements determine whether an S-Pedelec is the right choice for you.

What is a 45 km/h e-bike?

A 45 km/h e-bike, also known as an S-Pedelec, is an electric bicycle that supports you while pedaling up to a speed of 45 km/h. The motor power can be up to 750 watts. This distinguishes the S-Pedelec significantly from a normal pedelec, which only supports up to 25 km/h and with a maximum of 250 watts.

S-Pedelec vs. Pedelec

You should know the main differences between S-Pedelecs and pedelecs. Legally, S-Pedelecs are classified as mopeds. For these, you need a Class AM driver's license, an insurance plate, and a helmet. You are not allowed to ride an S-Pedelec on bike paths but must use the road. Pedelecs, on the other hand, are classified as bicycles. They do not require registration, a driver's license, or insurance. You are allowed to use bike paths with them and do not need a helmet.

Here is an overview of the differences:

Tip: An S-Pedelec is heavier than a normal bicycle. Riding without motor assistance is often more difficult.

Market shares show that S-Pedelecs account for only about 0.5% of the e-bike market. Standard pedelecs are much more popular with over 90%. This is mainly due to the stricter regulations for S-Pedelecs.

Target Groups

A 45 km/h e-bike is especially suitable for you if you want to cover longer distances quickly on a daily basis. Many commuters use S-Pedelecs to get to work faster. Sporty riders also benefit from the higher speed. For transporting loads in the city, S-Pedelecs offer an eco-friendly alternative to the car. In urban mobility, you can save time and be flexible with an S-Pedelec.

Technology & Performance

Motor & Acceleration

When you ride a 45 km/h e-bike, you feel the power of the motor immediately. Modern S-Pedelecs use motors with up to 750 watts. These motors provide strong torque and ensure quick acceleration. Models such as the Bosch Performance Line CX or the Brose Drive TF particularly demonstrate how much technology is inside these drives.

These motors provide progressive support up to 45 km/h. Assistance stops when you reach the maximum speed or stop pedaling. Many users report reliable performance over many thousands of kilometers. Manufacturers like Brose even provide a warranty of up to four years on their drives.

Tip: A strong motor helps you especially when starting at traffic lights or overtaking in city traffic.

Battery & Range

The battery determines how far you can go with your S-Pedelec. Most models offer batteries with at least 500 Wh. Some top models even exceed this. With a full battery, you can often achieve 40 to 80 kilometers in everyday life, depending on riding style and terrain.

Many factors influence the range:

• Your weight and the weight of your luggage

• The chosen assistance level

• Inclines and headwind

• The temperature

Some manufacturers rely on innovative battery technology. They offer fast-charging features or modular systems where you can carry a second battery. This gives you more flexibility on longer distances.

Note: In winter, the range often decreases by up to 30% because cold temperatures strain the battery.

Riding Behavior & Safety

With a fast S-Pedelec, you move almost like a moped in road traffic. The higher speed demands more attention and an adjusted riding style. You should always wear a helmet and ensure good brakes. Many models offer hydraulic disc brakes that decelerate reliably even in wet conditions.

New innovations for 2025 further improve safety:

• Sensors detect obstacles and warn you via display or acoustic signal.

• ABS systems prevent wheels from locking during braking.

• Intelligent lighting automatically adjusts to the surroundings.

Caution: Ride with foresight and always keep enough distance from other road users. The speed of an S-Pedelec is often underestimated.

Many S-Pedelecs feature a sturdy frame and wide tires. This ensures a secure riding feel, even at higher speeds or on uneven roads. You benefit from a sporty riding position and direct power transmission to the road.

2025 Regulations

If you want to ride a 45 km/h e-bike, you must follow special rules. The regulations for S-Pedelecs are stricter than for normal e-bikes. Find out what applies from 2025.

Driver's License & Minimum Age

You need a Class AM driver's license for an S-Pedelec. The minimum age is 16. Without this license, you are not allowed to use a 45 km/h e-bike in road traffic. You get the Class AM license after a theoretical and practical exam. Many young people take this license at age 15, but they are only allowed to ride an S-Pedelec from age 16.

Tip: Before purchasing, check if you have the appropriate driver's license. Heavy fines can be imposed without a license.

Insurance & License Plate

You need your own insurance for a 45 km/h e-bike. You will receive a small insurance plate that you must attach to the bike. The insurance protects you and others in the event of an accident. You are not allowed to ride without valid insurance. In addition, you need an operating permit from the manufacturer or the TÜV.

Note: Insurance usually costs between 50 and 100 Euros per year.

Helmet Requirement & Safety

You must always wear a helmet when riding an S-Pedelec. It must meet the ECE 22 standard. Normal bicycle helmets are not sufficient. The police check this regularly. Many models offer additional safety features such as ABS or automatic lighting. You should always ensure that brakes and lighting are functional.

Caution: Without a helmet, you risk not only fines but also serious injuries.

Road Use

With a 45 km/h e-bike, you are not allowed to drive on bike paths or in pedestrian zones. You must always use the road. This rule also applies in one-way streets. You usually cannot take your S-Pedelec on public transport because it counts as a motor vehicle.

Note: The police often check whether you are following the rules.

Other important rules

• The blood alcohol limit is 0.5 per mille, just like for a car. For new drivers, it is 0.0 per mille.

• Tuning is prohibited. If you make your S-Pedelec faster, you lose your insurance coverage and face criminal charges.

• Similar rules apply in Switzerland, but the minimum age is 14 with a moped license.

Remember: A 45 km/h e-bike offers many advantages, but you must adhere to all regulations. This ensures you are safe on the road and avoids fines.

Buying Guide

When purchasing a fast e-bike, you should consider several points. The right choice depends on your needs, your riding style, and the legal requirements.

Range

The range determines how far you can travel on a single battery charge. Many manufacturers state high values, but these are often achieved under ideal conditions. In practice, your weight, the terrain, and the chosen assistance level strongly influence the range. A battery with at least 500 Wh is considered suitable for everyday use. Danish studies show that users of fast e-bikes ride longer distances on average than classic cyclists.

Tip: Test the range during a test ride and ask for realistic practical experience values.

Motor

The motor is the heart of your e-bike. Models with a mid-motor offer a balanced ride and are durable. Brands like Bosch or Shimano are considered reliable. The motor power should match your intended use. For city traffic, less power is often sufficient; for hilly routes, you need more torque.

Equipment

Look for hydraulic disc brakes, as they provide safe stopping power even in the wet. The gear system should match your riding style. Internal gear hubs are low-maintenance, while derailleur gears are cheaper. A good lock protects against theft. Lighting and mudguards increase everyday utility.

Service & Price

A reliable local dealer is important for maintenance and repairs. Many dealers offer discounts or vouchers. You will often find more selection online, but less personal advice.

Tip: Always take a test ride. Test the weight, ergonomics, and brakes.

Legal

Fast e-bikes are subject to strict rules. You need a class AM driving license, an insurance license plate, and a helmet with ECE standard. The use of cycle paths is prohibited.

Critical reports show that high speed can lead to conflicts in road traffic. Consider whether you want to live with the limitations and obligations.

With a 45 km/h e-bike, you get powerful motor performance, modern technology, and clear regulations. These fast e-bikes suit you if you want to travel long distances quickly and flexibly.

• When buying, pay attention to range, motor, and safety.

• Check the legal requirements carefully.

Tip: Get information from specialist dealers and take a test ride. This is how you find the model that suits your everyday life.
