The December statistics are based on over 2.5 Mio. kilometers or 1.6 Mio. miles experiences from 434 ebike systems or users.
As usual no month without a motor issue! The last days I registered 35 new motor issues at Bosch Classic & CX, Impulse1.0 & 2.0 & 2.2, Yamaha PW, some of them were in the past.
Blaukohl (#199) His 2013 Bosch Classic had a cracked gear wheel after 16,000km. He bought an used unit and fixed the motor himself.
P256 (#419) has a Trekking bike since 2013. He wrote that every 4,500km the white big gear wheel is cracking. He is also fixing the motor with parts from used units.
Bosch CXCarlo (#433) was asking in a german FB group, if there is someone having also motor issues every 1,300km. First motor had a cracked right man bearing after 1,300km and the 2nd motor makes the same strange noise after 1,250km – both issues are warranty claims.
Impulse2.0E-Andy58 (#428) registered his bike in December 2017. He had two motor issues since mid of 2015.
- First motor started with duck noise after 2,500km – a warranty claim.
- Second motor started with duck noise just after 500km – motor changed.
- Third motor is running since 2 weeks, and guess what – right! Starting with duck noise – he is waiting for the new Impulse2.2 – delivery is planned in January 2018.
#386 and #388 had both loss of power after just 2,500km. The motors had been replaced in a bike shop – no warranty issues!
All other issues #385, #387 and #389-393 have unknown root causes. The motors had been replaced between 300km and 13,000km.
#400 and #406 had both complete blocked motors after just 2,500km and 6,600km. The motors had been replaced in a bike shop – no warranty issues!
All other issues #394-399, #401-405 and #407, #408 have unknown root causes. The motors had been replaced between 400km and 6,600km.
After arroung 500km the motor of #409 was replaced – reason unknown.
Lightrider (#413) had just optical reasons why his hub motor was changed – it was working properly until the removal.
Yamaha PWJanni (#415) made 4,900km when the motor stopped working. The unit had an electrical fault and could not be fixed. A typical warranty claim, Janni got a brand new motor.
Sollingbiker (#422) had to change the right main bearing after 7,000km. He wrote that it was no problem – maybe dirt and salt was responsible for this failure.
