We have 4 Bosch gen 4 motors and one of them has been replaced twice with 2600km and 2700km ridden. Usual issue for Bosch is the 8 notch lockring coming loose which probably ruins some motors. That has happened to 3 motors of those 4. Those did not ruin the motor. But based on personal experience I believe the Bosch failure rate is really high. 2 different motors broken in the same way. And the 3rd motor that was replaced to that same bike had some issues right away. While it did not break the bike was just returned and we got the money back. So that is 50% failure rate for Bosch in our case. 2 year warranties on these Bosch bikes. Both broken motors warrantied. That's why we ended up returning the entire bike because at that pace that bike is eating a motor per year. I would believe Brose has the highest failure rate because the belt comes off every 1000-4000km. If you had people riding enough the Brose failure rate might be even higher.
I am very pleased with my TQ motor, no issues so far, been through deep water, mud galore, frigid temperatures and high temperatures. Actually after realizing this I should probably get it serviced 😅
This poll doesn't provide much information. How old are the motors, and how far have they been used? If all the Bafang motors are 1 year old and the Brose motors are 3 years old, does that mean Bafang is better? I believe the most important factors are the quality of the service and how quickly the turnaround is for motor repairs. And here, Brose is probably the best, with Bosch as number two. Also, when it comes to how service-friendly the motor is.
You completely miss the level of service, I had a Bafang motor with critical failure at arrival (online). I tried to get it serviced under warranty and just gave up after two year being ignored. When I thought my Bosch motor was a bit loud my local mechanic checked it out and it was normal, however Bosch sent new gearing and let the mechanic replace it with some extra lubricant under warranty. I don't care about these statistics, I rather have better service even if the product has slightly more failures, I am staying with Bosch for the rest of my life!
