Brose is one of the leading manufacturers of electric bike motors, offering a range of models for different types of e-bikes. However, like any mechanical device, Brose motors are not immune to problems and malfunctions. In this blog post, we will discuss some of the common issues that Brose motor users may encounter, and how to troubleshoot and fix them.
Complaints
One of the most frequent complaints about Brose motors is that they make a loud noise when pedaling. This can be caused by several factors, such as loose bolts, worn bearings, damaged gears, or misaligned chainrings.
To diagnose the source of the noise, you can try the following steps:
- Check if the motor bolts are tight and secure. If they are loose, tighten them with a torque wrench according to the manufacturer’s specifications.
- Check if the motor bearings are in good condition. If they are worn or damaged, you may need to replace them with new ones. You can test the bearings by spinning the crank and listening for any grinding or clicking sounds.
- Check if the motor gears are intact and lubricated. If they are broken or dry, you may need to replace them or apply some grease. You can inspect the gears by removing the motor cover and looking for any signs of wear or damage.
- Check if the chainrings are aligned and compatible with the motor. If they are misaligned or incompatible, you may need to adjust them or replace them with suitable ones. You can check the alignment by measuring the distance between the chainrings and the motor casing.

Common Problems
Another common problem with Brose motors is that they lose power or stop working altogether. This can be caused by several factors, such as low battery level, faulty wiring, overheating, software glitches, or sensor errors.
To diagnose and solve the problem, you can try the following steps:
- Check if the battery is fully charged and connected properly. If it is low or disconnected, recharge it or reconnect it securely.
- Check if the wiring is intact and free of any cuts or corrosion. If it is damaged or dirty, repair it or clean it with a soft cloth.
- Check if the motor is overheating or has a thermal protection feature. If it is overheating or has a thermal protection feature, let it cool down for a few minutes before resuming your ride.
- Check if the software is up to date and compatible with your e-bike model. If it is outdated or incompatible, update it or contact your dealer for assistance.
- Check if the sensors are working correctly and calibrated properly. If they are malfunctioning or miscalibrated, reset them or contact your dealer for assistance.

Brose 2.2 Motor Problems
If you own an e-bike with a Brose 2.2 motor, you may have heard about some of the problems that can affect this model. The Brose 2.2 motor is based on the Brose Drive S Mag, which is one of the best motors on the market, but also one of the most unreliable. Many riders have reported issues with belts breaking, noise, vibrations, and power loss, which often result in having to replace the entire motor.
Software Update
Fortunately, Brose and Specialized (who use the Brose 2.2 motor on their Levo and Kenevo models) have responded to these problems and released a software update that reduces certain peak loads, putting less strain on the belt and increasing its longevity. The software update should not have any negative effects on the motor’s performance. The latest motors also come with reinforced belts and other technical improvements to improve noise reduction and durability.
The software update is available now for all current motors and can be installed at your nearest dealership. If you have a Specialized Levo or Kenevo from 2019 to 2021, you can also benefit from a warranty extension from 2 to 4 years from the date of purchase, which is transferable and does not require any other conditions.
