Change the language to English. Go to the top menu for Engines & Statistics (Motoren & Statistiken) and select mid-drive or hub motors. Voluntary registration so the sample size is small, and it's predominantly European so the engines will be less powerful/less stressed than North America, but I haven't seen anything else like this.

Hello,

I updated the mileage and the motor failures in several motor systems.
  • Bafang BBS
  • BionX
  • Bosch
  • Brose
  • Impulse
  • Cute
  • EasyMotion
  • MAC
  • Impulse
  • Panasonic
  • Yamaha
https://pedelecmonitor.wordpress.com/mittelmotoren/

The idea:
  • show the mileage and failure time of different mid and hub motor systems
  • make it compareable
  • give possibilities to interpret the data focussed on reliability
  • have 50 to 100 members for each system
  • show real customer usage
  • collect failure types, problems, solutions
One example for the reliability of different systems:




So which one is more reliable? What do you think? x-axis is identical!

One example for the evolution Gen1 --> Gen2:





Homework is done, i think so.

Please help to show the real customer view with your mileage and your failures!

What do you think, add an english version?

Thx for your feedback,
you think all texts should be in english or is it (for the first change) helpful to have charts in miles and in english?

I was also having the same problem understanding the charts BUT, when I studied the charts carefully, it is evident what is happening. Need to look up the heading, the motor in question, and then the users and their still working or failure estimate will be more clear.

Nevertheless, there ought to be a section where you can put a different OEM/Non brand manufacturer, type of motor setup: Planetary/geared or direct etc....and put the distance travelled so far.

I cannot believe that the Bafang Middrive 2 has gone so far as described here. Mine failed around 1600Km. Garbage.

My planetary 1000 Watt hub drive already has 1600 kms in a shorter period of time and is still going strong as the first day.

About 1.200.000 kilometers or 790.000 miles are the base for the JULY-statistics.

***
28 new failures were mailed in July, :eek:. They occured at Albers Neodrive, Bafang, Bosch, Impulse and Puma.

Over 1.3 mio miles or 2.2 mio kilometers are the base for the NOVEMBER-statistics.

This month just 7 new motor issues were reported - some Bosch mids and some hub drives.

All motor issues are now summarized in a google table with
  • runtime
  • date
  • failure describtion if available



Last month there were a lot of Stromer (St1 and ST2) biker that shared their mileage - very impressive data!

Hi @Dewey ,

I got a bit help. Now I have a automated database on www.pedelecmonitor.com.



New are user accounts for up to 4 different bikes. The experiences are reduced and shown on just one page. Everybody can add info to mileage and repairs to his own bike.
Example:
Look for my bike as an example

Melder: ingologan
Pedelec: Reaction Hybrid SL

In addition we created several charts for Bosch mileage, Yamaha mileage, Stromer mileage .....

Subscribed! Beyond impressive, this collected data is a gold mine for ebike motor manufacturers everywhere.

Yamaha PW drive on a 2017 Haibike Full FatSix. 9800 miles. 0 failures of any kind in the e-drive system, save for one loose spoke sensor magnet.
