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. *** Jump to english start-page! https://pedelecmonitor.wordpress.com/mittelmotoren/ Directlinks...

@Gubbins the bike is really new, so I cannot imagine that there are problems with the bearings, especially because you do not like the wet and dirty rides. I share @d8veh theory - motor bolts - also possible pedals tight? crank arms tight? -> oh i read, you checked already Correct, I add my...

@Gubbins I have several questions: - how old is the Scott bike - what type of Bosch motor is implemented - what is the current mileage - when do you use the bike (p.e. always / just sunny days)

Due to a lot of failed Impulse2.0 motors in Europe in 2015, Daum Inc. & Derby Cycle (Kalkhoff, Focus, ...) improved the design of the motor and modified the software. We got some information about this from 50cycles some pages ago. The new 2017 motors are hopefully more reliable. An abstract...

Thanks for your info. In relation to the working CX motors here in the forum, it is not that much. So I have 1 failed unit out of 25 in the pedelecmonitor. I think in reality the motors are much better. But an estimation w/o data is really difficult and nobody would accept, right?

Over 1.000.000 kilometer or 650.000 miles motor experience are basis for the JUNE statistics. The first registered damage in a Bosch CX occured. In the germen Pedelecforum I started a monitoring for the newer Impulse2.2 with changes in construction and software compared to the 2.0. For more...

Maybe it's because the very beautiful white rack/carrier costs 200,- ? :p

Here around Stuttgart there are just a few with failures, most cases are broken gear wheels with the classic. The thing is, I'm still using a german website. Although I use simple words and grammar, google translator sometimes build sentences with no sense! Maybe more people would join if I...

Nearly 900.000 kilometer or 550.000 miles motor experience are basis for the APRIL statistics. There is still no motor damage for the Bosch CX. Also the Performance shows a good reliabilty. On the other side, there are again more damaged units from the Impulse1.0 and 2.0. New members from...

@martincecho why is your display stopping at 10.000km or miles? Are you sure it's an impulse2.0 ? Even the bigger displays can show more than 9.999km? Which display do you have? Enjoy your rides with your son ;)

Very interesting. So also in Germany we have some 10.000+ with the Impulse2.0. The date of manufacture of those units is spring and summer 2014. The 2015, 2016 and the late 2014 were beginning to have problems sporadically. Can you post year and month of manufacture of your unit or the first 3...

WOW, even more pages to read here. Here are my current statistics to Impulse motors and all the others to. Thanks to all in England and Scotland, that help to get a real picture from customer side! Hi Scott, there are a few more failures of Impulse2.0, but also in Germany, France, Belgium and...

Good idea, I will also implement the data of my (old) first google table under the charts! Thanks to all for the ideas and discussions in the threads and in the conversations. Sorry, it take a lot of time to introduce the ideas in german and english. But two separate websites are a way to much...

More than 400.000 kilometer or 250.000 miles motor experience are basis for the JANUARY statistics. The first registered Bosch CX members have now nearly 2.000mi, until now there was no motor failore or damage. There are new members with the Panasonic motor and the Impulse1.0 with really high...

Thank's for your answers and discription of the failure chain. That helps a lot. Now there are further questions: 1) From which motor# or date of production is the new improved impulse2.2? 2) Even the fixed motors in August 2016 with better parts had problems (mine lasts just 1 month or 800km)...

More than 340.000 kilometer or 200.000 miles motor experience are basis for the DECEMBER statistics. Meanwhile there were also some motor damages reported concerning the BOSCH Classic and the Performance. The Impulse2 ist still bad. First pedelecs registered with Shimano Steps and ImpulseEVO...

To FIRST - I have the same point of view. I suspect 2 initial issues. I think one is the bearing that is responsible for the noise during the ride in power modus up the hill. It's getting louder until the support completely stops. --- EDIT: I found a post in the german pedelecforum, where is...

Done - now in English and in miles. Current mileage: Thanks to all that registrated and gave their mileage.

Hello @4bound , i wish all your information included, the working and the failed impulse2 units. I try to show the complete situation, not only failing units. The website is online since 3 weeks, I have not really thought about an english version, but it is necessary. I started to include all...

About 180.000 kilometers or 110.000 miles are the basis for the NOVEMBER statistics. Not bad for the 1st month. Further charts are shown on www.pedelecmonitor.de. Any positive or negative feedback?
