I've had a few runs without mine and no issues.
With narrow/wide chain rings loosing the chain has become far harder.
Maybe they install on Ebikes due to the torque factor however I've had no issues yet ..

I feel for you Rebie. Agree it's rare any reviews take into account motor reliability and support. It's mostly about power etc.
If Shimano are making an even more complex unit and the current can't be maintained then that bodes for another non maintenance throw away unit.
A big progression in...
You can remove the chain ring and feed over crank arms ... mine is 34T and will go over pedals too after removing the small torx bolts holding ring onto spider arms.
Why do you need to remove the toothed ring? Presuming the one behind the spider arms for chain ring ? I dropped my motor out. Much easier than I thought and you can clean it all up and use specific electric contact spray on the 3 plugs.
I think just trying to keep it clean, avoiding as above...
If traditional MTB are due to go extinct this puts even more onus on manufacturers to provide units that are serviceable like a motorbike, car, normal ebike etc. I won't rely on just an ebike until the service aspect improves
Agree with all above.
Infancy creates issues however there needs to be an iterative approach to design, service and support. That way development occurs.
I'm sure simply bearings can replace Bosch bits maybe also Brose ?
Bosch actually seem top at the moment for overall design and support ...
I understand different experiences from different folk howeveythete are still some howlers on the E8000:
Non gasket offside cover that lets crud into all the power/torque sensors
A BB going and scrap the motor?
Brose/Bosch can be pulled apart and repaired a Shimano cannot.
And I've heard of...
Agree with Shimano Vs Brose Vs Bosch.
I'm not bashing performance. Shimano got it right early on. Plus created a motor with normal sized chain ring and positioned axle so chainstay length wasn't huge. Hats off to them for that. Game changer.
However I've known of many bikers in the UK who...
Not on mine after twice sending back and one replacement on 750 miles.
Granted do bike in an area that's hard on components and when the motor works is a great unit.
Ah they are still alive then.
However will it be a matter of "if out of warranty issue throw it away"
I have to say my choice of future EMtb isn't just about kinematics, geometry, motor power or apps but which company provides a good life cycle support of the motor. The one part of an EMtb...
I ask as the e8000 is now around 4 years old. There is limited field service support for the motor apart from "replace it" and Shimano, unlike say Bosch and Brose have never specialised in motors.
Thoughts ?
I've downloaded ST Unlocker the £1.50 version not the more expensive deristrct.
Fantastic app. Connects a dream. You adjust in each generic power mode specific elements. So:
% assist
Total NM
Total wattage
Also you can adjust wheel size if mullet etc and control elements such as lights...
A short stem and wider (780+) bars assist with steering feel. Unless shorter arms.
The whole forward geometry was based on running a 30mm or less stem.
They key is to get components that can be upgraded. Example: Yari fork is great especially when upgraded with a higher volume negative...
At this amazing price It's good to have a new gen Bosche motor too. Some brand new swanky looking expensive EMtb still use the now pretty dated e8000 that cannot be repaired...still even after launch several years ago. The e8000 was groundbreaking in its day, still delivers a good feel on trail...
Snapped axle; That must have been some hit or lateral force to do that. Maybe EMtb need even bigger diameter through axles ?
I'm surprised wheel didn't blow out first.
Which bike ?
My sensor was bang on 17mm which in your manual suggests is max (3-17mm) so if my rear wheel wobble was more than a few mm then that would cause a sensor fault through zero pickup shutting motor down until next revolution.
It's making more sense....
On another wheel related note I swapped my...
