Calculating a failure rate is rarely possible, I totally agree! So I decided to make it in a different way with a different data base. I just present statistics and information - everybody can use it and make its conclusion. www.pedelecmonitor.de Thanks for your review and your statements, they...

Hello, due to the high failure rate for the impulse2 motors, and the fact, that I had my 5th motor, I first listet all failures of other forum members (german, english, french) in a google table. https://docs.google.com/spreadsheets/d/1WQ6DqHS4uXCNybjnlXZD3dOU_ylw5Qwsc0_89coCsF0/edit#gid=0...

Due to the high failure rate for the impulse2 motors, first I listet all failures in a google table, some of you know it. Now I startet a new project to show and compare the reliability of the different middrive systems. I uploaded my new webpage www.pedelecmonitor.de this week and hope, lots...

Found some Motor IDs 20.03.2015 #328841 (my last one) 27.09.2016 #588910 from a german forum member 557 days later were 260.069 additional motors produced 557 days are ca. 80 weeks 260.069 produced motors in 80 weeks are ca. 3.268 motors per week 3.268 produced motors per week are 654...

@Tomtomato @Will Tinker and all the other Focus Crater Lake bought in 03/2015 repeatition for the new followers: - 1st motor changed (03/2015) after motor mileage 120km due to creak noise and vibration in POWER mode - 2nd motor changed (09/2015) after motor mileage 3.180km - same failure -...

@d8veh Thanks for this hint, i used the search but had a wrong keyword.

Hi, I'm collecting some field data from the Impulse2.0 motor. Yes, I have also problems with my bike. When I bought my bike, the Derby support wrote that the motor can work for 30.000km. :confused: SURE! So what I'm interested in is: - # installed motor, i.e. 1st / 2nd / 3rd /.... - Mileage of...

Today the motor pawl failed. When I stopped pedaling while the bike continued rolling, the motor didn't stop spinning ... KLACK ... another turn .... KLACK .... another turn .... I stopped this after about 400 meters. 1st motor - bearing failure 2nd motor - bearing failure 3rd motor - pawl...

hey flecc, in Stuttgart is a big construction area, they are changing the main station. The dead end station is going to be an undergroundstation with rails at both sides. That has an effect on all other running trains around and passing the main station. Oh they made a change. In Germany...

Hi, no I'm not driving a Mercedes or a Porsche, sorry. But I bought a Focus with Impulse2 motor in March 2015 to commute between home and work. It's not possible to go by car in Stuttgart due to daily traffic jam and since 3 years it's also not possible to go by train because of daily failures...

Hi, i'm a member of the german pedelec forum and collecting information about the Impulse2 life time (endurance) and the occurence of failure like clacking or squeaking. I have the idea to make an mileage estimation for the occurence of the different failure mechanism. Thanks to Tomtomato for...
