Thanks Rob.
Currently I'm sitting here thinking about getting rid of the bike. Today has seen my second bearing failure in a little over a 1,000miles, and to say that I currently feel fecked off is an understatement.
After having spoken to a well respected engineer about the first bearing failure, the conclusion was that chain suck had probably contributed to it. Something had to give when the chain repeatedly locked solid, and as the chain never snapped, the load had to be transferred somewhere else, and the next weakest link, was the bearing.
Also, given the rapid rate that I am eating sprockets, I suspect that the Bosch system does not like being used in an unassisted mode for any length of time, or even possibly in eco mode off road. My feeling is that the extra required pedal force is placing strain on the bearing shaft. That is just my opinion/guess though.
Bosch only rebuilt the first motor, and did not supply new one, so perhaps it could be that they just didn't do a good job of it, I don't know. The rebuilt motor was certainly quieter than the original motor, and just recently I have started to feel that I actually liked and enjoyed the system. Not now though. I don't enjoy doubt about reliability.
This was the first bearing failure.
And the with the second current bearing failure, the bike just sounds like a bag of rusty nails, but hasn't yet shat itself.
Currently I just don't see a future for me and the Bosch system.
Ref the thron, in truth something about it doesn't float my boat or excite me, but I can't quite put my finger on what it is. I'm just starting the process of looking at alternatives, and won't be looking for anything that has a small front sprocket. I might well investigate bikes fitted with the Yamaha motor.
