Shimano, much more than just a motor
What makes Shimano unique is that the brand doesn't just manufacture motors, but virtually every moving part of a bike. This allows it to perfectly optimize the collaboration between the motor, transmission, and brakes, which are often from the same brand. The result is a system renowned for its very natural riding feel.
Shimano motors, often referred to as STEPS (Shimano Total Electric Power System), are generally compact and lightweight. The drive unit is mounted directly on the frame, ensuring a low center of gravity and a more maneuverable bike.
Overview of models and specifications
Shimano offers a wide range of motors, each designed for a specific type of cyclist. Here are the main models, from the simplest to the most sporty.
1. For urban cyclists: Shimano STEPS E5000
The E5000 is designed for quiet urban use. It is Shimano's lightest and quietest motor.
Key features:
- Weight: ± 2.5 kg
- Torque: 40 Nm
- Very quiet
- Focused on comfort
Suitable for:
- commutes
- shopping
- flat roads
Under ideal conditions, the range can reach up to 185 km in eco mode.
2. The versatile: Shimano E6100 and EP5
These are truly versatile engines for those who want more than just urban transportation.
| Engine | Couple | Weight | Type of use |
|---|---|---|---|
| E6100 | 60 Nm | ± 2.76 kg | Hiking, hilly terrain |
| EP5 | 60 Nm | ± 2.4 kg | City + leisure activities |
The EP5 is newer, more compact, and slightly more economical. It offers smoother assistance and reduces wear on the chain and sprockets. It's a smart choice for those who want a single, versatile bike: not extreme, but modern.
3. For adventurers and athletes: EP6 and EP8
These engines deliver real power. Both offer 85 Nm of torque. That's a lot. Really a lot.
| Engine | Couple | Weight | For whom |
|---|---|---|---|
| EP6 | 85 Nm | ± 3.0 kg | MTB, trekking |
| EP8 | 85 Nm | ± 2.65 kg | MTB |
The EP8 is lighter and responds more quickly. On technical trails, the difference is clearly noticeable.

What sets Shimano apart from other brands?
Shimano sets itself apart from competitors such as Bosch through several technological innovations and specific riding sensations.
A sporty and direct driving experience
While some competitors are known for their extreme smoothness, Shimano is known for its "sporty and direct" character. The motor responds quickly to your effort, offering a dynamic experience that is ideal for cyclists who like to stay in control.
How does shifting work with Shimano Di2?
Di2 is a particularly intelligent electronic gear shifting system. It offers the following features:
- Start Mode: always start in a low gear
- Auto Shift: automatic gear shifting
- Free Shift: gear shifting without pedaling
Free Shift is particularly useful in turns or on technical descents.
E-Tube Project application
All modern Shimano motors can be customized via the E-Tube app. You can adjust the assistance modes (Eco, Trail, Boost), view your ride data, and perform software updates. Your smartphone becomes the brain of the bike.
Which motor for which type of cyclist?
The choice of engine depends entirely on your usage.
- City and daily commutes: E5000 or E6100
- Hiking and travel: E6100 or EP6
- MTB : EP6 or EP8
- Cargo bike: EP6 Cargo or EP8
Strengths and weaknesses
Highlights
- Natural riding sensation: sensors accurately measure your effort.
- System integration: excellent compatibility with Shimano brakes and drivetrains (especially Di2).
- Reduced weight: compact and lightweight motors.
- Customization: advanced software settings via the E-Tube application.
Weaknesses and points of attention
- Repairability: Shimano rarely supplies separate internal parts. In the event of a breakdown outside the warranty period, the entire motor often needs to be replaced, which can be expensive (sometimes around €900).
- Noise: Powerful motors such as the EP8 may be more audible under load or when coasting.
- Navigation: Shimano screens are functional but offer fewer advanced navigation options than some competitors. Navigation is often done via smartphone.
Conclusion
Shimano e-bike motors are an excellent choice for cyclists looking for a sporty, lightweight, and natural ride. The brand's strength lies in the seamless integration of the motor, battery, and drivetrain, ensuring a smooth riding experience. Whether you're riding around town with an E5000 or tackling the Alps with an EP8, Shimano has a motor to suit every adventure. However, it's important to consider the limitations of out-of-warranty repairability; insurance or an extended warranty can offer additional peace of mind.
