Bosch, Shimano, or Bafang: Which motor brand affects the value of your e-bike?
In the world of e-bikes, people often focus first on the eye-catching design, the trendy frame color, or the thickness of the tires. However, to accurately assess the value of an e-bike, you must first and foremost consider the motor. It is the beating heart of your bike. It not only determines how smooth and natural your ride feels, but it’s also the most significant factor in your e-bike’s resale value and depreciation.
As an e-bike specialist refurbished, Upway sees hundreds of bikes from every possible brand come through its doors every day. Whether you want to sell your current e-bike or are looking for a smart investment in the used market, the motor brand is worth its weight in gold. But what is the real difference in value between an e-bike equipped with a Bosch, Shimano, or Bafang motor? And what hidden factors determine whether your bike will hold its value? In this article, we dive into the world of e-bike motors and their impact on your wallet.
Key Takeaways
Before we dive deeper into the technical details, here are three key takeaways about how the motor brand affects the value of your electric bike:
- Bosch, the undisputed leader in residual value: E-bikes equipped with a Bosch motor depreciate the slowest, thanks to the brand’s exceptional reputation, proven long-term reliability, and ongoing software updates.
- Shimano offers consistent value thanks to its mechanical synergy: the seamless integration of Shimano motors with the brand's own drivetrains and brakes allows these bikes to maintain a strong and sought-after position in the used bike market.
- Bafang, the budget champion, but with faster depreciation: Bafang offers impressive torque at an attractive purchase price, but e-bikes equipped with this motor lose their value more quickly on the used market due to a less refined ride and limited brand recognition.
Bosch: The "Toyota" of electric bike motors
If you ask your local bike shop which brand dominates the market, the answer is almost always the same: Bosch. In the world of e-bikes, this German brand has built a reputation comparable to that of Toyota in the automotive industry: unmatched reliability, rock-solid durability, and a massive network of professional dealers. Discover our wide selection of e-bikes equipped with a Bosch motor at Upway.
Why a Bosch motor increases the value of your bike
- Proven lifespan: An electric bike motor lasts an average of 5 to 10 years, or about 50,000 to 100,000 kilometers. Bosch motors are known for reliably covering tens of thousands of kilometers without any significant mechanical issues.
- Huge market demand: major traditional, high-quality brands such as Gazelle, Batavus, and Sparta are widely equipping their electric bikes with Bosch systems, creating a steady stream of buyers in the used bike market.
- The Smart System and the Flow app: Thanks to the Bluetooth connection with your smartphone, built-in navigation, trip logging, and regular software updates, a digitally evolving engine simply ages more slowly, which significantly boosts its residual value.
The downside: Bosch's premium quality comes at a high price. In addition, Bosch's software is completely closed-source, which means you must go through an authorized dealer for any diagnostics or updates.
Shimano: The Power of Mechanical Synergy
Bosch's most direct and significant competitor is the Japanese company Shimano. For over a century, Shimano has set the global standard for drivetrains, chains, and brakes. Their STEPS mid-drive motors are specifically designed to work in perfect harmony with these mechanical components. Discover our lineup of e-bikes equipped with a Shimano motor.
How Shimano Affects the Value of Your E-Bike
- A perfectly harmonious mechanical system: since the motor and drivetrain are from the same manufacturer, the bike shifts gears with remarkable smoothness, which significantly reduces wear on the chain and sprockets.
- Lightweight and compact: Shimano motors are often more compact and lighter than Bosch motors, which makes it possible to design bikes that look and ride like a “traditional” bike.
- Excellent service and great parts availability: Bike repair shops around the world know Shimano parts inside and out, and parts availability is excellent.
The downside: Outside of warranty coverage, a Shimano mid-drive motor can sometimes be difficult to repair individually in the event of an internal failure. Repair technicians are then often forced to replace the entire motor unit.
Bafang: plenty of torque, but it loses value faster
The Chinese brand Bafang has shaken up the e-bike market in recent years by focusing on the budget and mid-range segments. Bafang mid-drive motors are primarily found on e-bikes from brands such as Cortina, Amslod, and Brinckers. Check out our selection of e-bikes equipped with a Bafang motor at Upway.
How Bafang Affects the Value of Your Bike
- Maximum power for your money: While entry-level Bosch and Shimano motors often deliver 40 to 50 Nm, most Bafang mid-drive motors offer an impressive 80 Nm as standard.
- Faster depreciation: The system lacks the refinement of its European and Japanese competitors. The motor is noisier under heavy load, and the assistance can sometimes feel a bit jerky.
- An open system for DIY enthusiasts: the software isn't locked down, replacement parts are inexpensive, and a simple programming cable lets you adjust the motor settings yourself.
Upway 's Hidden Factors: What Really Determines Resale Value?
When we purchase electric bikes from Upway and professionally refurbish them for a second life, we look beyond the brand name printed on the motor. Three hidden factors determine an electric bike’s residual value on the used market, and they are directly linked to the motor brand.
1. The “tuning risk” and market confidence
Because the Bafang system is so open and accessible, its motors are relatively often “tuned” by their owners. In the secondhand market between private sellers, this poses a huge risk to buyers, because a motor pushed beyond its limits has operated under much higher internal stresses, which drastically reduces the lifespan of the gears and battery cells. With Bosch and Shimano, the software is tightly locked down, making illegal tuning extremely difficult.

2. Digital Health Certificates
One of the most important steps in our refurbishment process at Upway is performing an electronic diagnostic check on the bike. Using advanced digital diagnostic systems from Bosch and Shimano, we create a comprehensive “health report” for the bike. We can see exactly how many full charge cycles the battery has undergone and whether the motor has logged any internal errors. To learn all about the overall longevity of an e-bike, be sure to read our article on the lifespan of an electric bike.
3. Circular Repairability (Remanufacturing)
Even though Bosch parts are more expensive, a healthy independent market of specialists in Bosch motor overhauls has developed in Europe. This circular potential gives an e-bike equipped with a Bosch motor a solid “floor value.” With Shimano, overhauls are a bit more complex, which tends to lead you more quickly toward a complete, costly replacement.
Comparison: Bosch vs. Shimano vs. Bafang
| Criteria | Bosch | Shimano | Bafang |
|---|---|---|---|
| Residual value | Very high | High | Average |
| Average couple | 40–85 Nm | 40–70 Nm | 45–80 Nm |
| Software | Closed | Closed | Open |
| Price segment | Premium | Medium-high | Entry-level to mid-range |
Hanna's Advice
Are you trying to decide between two used e-bikes with motors from different brands? Always ask for the digital health certificate for the battery and motor. At Upway, it's provided automatically, regardless of the brand!
Conclusion: Which engine brand offers the best value?
If you're looking for an e-bike that will still retain a significant portion of its value in three or four years, a model equipped with a Bosch mid-drive motor remains the undisputed leader in value. Are you looking for an extremely reliable e-bike with a smooth ride, where all the components work together seamlessly? Then Shimano is an excellent choice. Bafang is the ideal choice if you want maximum power right away at an attractive entry-level price, but keep in mind that it will depreciate more quickly over the long term.
At Upway, we believe that every high-quality e-bike deserves a second life. Through our professional reconditioning process, we restore every Bosch, Shimano, or Bafang e-bike to perfect condition, complete with a 1-year warranty and a tested battery.
Frequently asked questions
How long does the motor of an electric bike last, on average?
A high-quality electric bike motor from a reputable brand lasts an average of 5 to 10 years, or 50,000 to 100,000 kilometers, provided the bike is properly maintained.
Why does a Bosch motor hold its value better than a Bafang motor?
This is due to trust in the brand, the quality of the software, and the system's resistance to malfunctions. Bosch motors use highly sophisticated torque sensors and a closed-loop system, which prevents any harmful software tuning.
Does the motor's torque (Nm) affect the residual value of the electric bike?
Yes, absolutely. Electric bikes with higher torque are more versatile and therefore more sought-after on the used market, which helps them retain their value better.
Which is better for the bike's performance: a torque sensor or a rotation sensor?
A torque sensor significantly enhances the experience because it precisely measures the pressure you apply, providing a more natural riding sensation than a rotation sensor.
Is it safe to buy a used e-bike equipped with a Bafang motor?
Yes, definitely, as long as the bike comes from a reliable source. With an electric bike from refurbished at Upway, the bike is thoroughly inspected, and you automatically receive a 1-year warranty.
