Ok update on the failing Dyname 4.0
My bike shop was very nice and understanding about the problem. They would just contact RM, order a new motor and put it in. For the shop it was a clear case, a bearing that was about to go tits up and was already making noise. Thats what warranty is supposed...
Sure, i will.
I cant get to a dealer right now, because im traveling Spain. So i had the choice to either stop biking, or just continue until it catastrophically fails. I choose the latter.
And hey, until now its holding up just fine (~200km later). Just some loud grinding noises and clicking...
So it seems that my Dyname 4.0 is starting to fail. There is a horrible clicking (bearing) noise coming from the upper motor bearing nearest to the small chain cog.
It has done 5500km...
Should be a case of warranty. But still, bit disappointed about this weak spot of the Dyname 4.0 motor.
I...
Im not a fan of motor bolt pattern and battery standardization. Some things just shouldnt be standardized. It hampers innovation. Apply standards where it makes sense, but in this case it doesnt make sense.
There is a reason why you cant fit an AMD cpu in an Intel system. There is a reason...
Well we can only guess what motivated Shimano to change the design. However the grinding and misalignment problem of those gears is seen with both the early model and the later model.
I personally think they shouldn't have used helical cut gears, because of the axial force involved that pushes...
Keep in mind that the overtime pack is not just a 2nd battery connected to your bike. It is a mobile charging device, similar to your wall adapter. So it needs to provide a regulated voltage and current to charge the main battery properly.
Now technically you could just connect 2nd battery in...
Yeah i have no clue either. Ive opened my motor 6 or 7 times and never had the issue.
Maybe something that was calibrated gets out of spec after disassembly? Perhaps it has something to do with splitting the crank axle in 2 pieces, which my motor didnt allow because it is glued together. See...
Look for a spare parts E8000.
Those gears are swapped very often because they are one of the weak points of the E8000. So make sure the spare parts E8000 you want to buy is low mileage and has a pristine set of those gears inside.
I have the Leatt for a couple of years now. Like it very much. Only thing ive changed are the side clips. They are bulky and tend to create a pressure point on the ribs. If you fall on your side the risk of rib fracture or bruising is increased by the clips.
So i removed the clips and replaced...
