New headset bearings for the Rail, don’t know how good they will be but they will do until I can find some Cane Creek Hellbender bearings

Got a service kit for my bosch motor. Motor feels like new now😀 View attachment 78816
Wow, now I see why Bosch motors fail so often, plastic is everywhere, and it looks like now the reason for that plastic is not safety of another components, but weight savings and cost savings. Yamaha motors use just one plastic gear in the low torque place near the electric motor for safety reason, other gears are out of metal.

Will be good when they replace plastics with an alternative such as Nanocellulose. It doesnt have the bio waste of plastic and is way stronger for the same or similar weight.

Yah, those plastic gears make the motor weight slightly less, they are cheaper, and they produce less noise. All these characteristics are purely for marketing to sell more motors, they do not care how long it will last, as long as it is silent, lighter than another motors and cheaper, people will buy it more because of people believe all the motors are equally reliable, but they are not.

It where not the plastic gears that failed! They where still in perfect condition if I just cleaned them and gave it regrease!

It where the bearings that failed and let water into the motor onto the metal gears where there was rust in the grease. Luckily no corrosion on the gears
Beneath the plastic gears are the metal gears

FFS ! Does it ever end .. Depending how you interpret your figures a Bosch is 2-4 times more reliable than a Yamaha .. do we have to continually follow you around to stop you trolling Yamaha adverts everywhere.

You literally said in a post the other week that Yamaha used a plastic gear to stop failures elsewhere in the motor and an example of good design was that the plastic gears hadn't failed ?!?!

From yesterday's post which you've ignored and then jumped back on the troll a thread wagon (that was in a bosch thread). I know it's the festive season and a few people will have been celebrating with some liquid fun, but normality still exists out there somewhere.

There is a reason they distribute only Haibike and Giant with Yamaha motors. They don't want their business to be bankrupted due to the issues with another brands motors.

I'm a big fan of Yamaha, but I wish you would stop living in a world of denial and dreams that their motors are somehow miraculously more reliable than everyone else's and repeatedly sprout off about it as if we live in some parallel universe which has no bearing on reality - it just makes you sound like you work for Yamaha. They're about on par with Shimano, which are far from being the most reliable motors.

Haibike also ship bikes with motors from Bosch, TQ and Yamaha. Likewise, Giant use motors from several suppliers which they re-work under their syncdrive program.

Here's just one users experience of Giant ownership/yamaha motors and he's certainly not alone so please stop being unrealistic. Hopefully the new PW-X3 will be a huge improvement over the X2.

Collected brand new: Feb 7th 2020.
This bike was a trade up for my rejected MY19 E+3Pro Which had a hub, a motor, a fork, 3 controllers and was generally nothing but trouble. 🤨

5th March = Ride One Controller failure (FLED28-10)
Had to wait a week for a new one to come

New one fitted and lost auto mode and ANT+ as they installed controller for a 2019 bike. (FLED28-07)
Had to wait again for a 2nd one to arrive.

25th March. = Speed sensor failure.
(Cracked plug due to placement in casing)
2 weeks wait. New one fitted 10th April.

15th June = Battery failure.
3 weeks wait until 6th July for a new one so bought a spare at same time.
That came faster than the warranty unit.

20th July = Motor bearings failure. (1st motor failure)
4 weeks wait until 21st August for her 2nd motor to be fitted.

20th July = Dropper post changed under warranty whilst it was in.

6th September = Ride One Controller failure
1 week wait until new one arrived 14th September (FLED28-10)

22nd November = Motor failure (2nd Motor failure)
26th November, her 3rd motor was installed.

14th December = Ride One Controller failure
1 week wait until 20th December. (FLED28-15 this time.)

18th January 21 = Dropper post failure again. (twists)
Shop said it needs to be sent to Giant for inspection which I wasn’t willing to do as I would have no bike.
I found a service kit for sale in USA so bought it and fixed it myself. Why cant these be available in UK?

19th May 21 = Motor bearings failure again. (3rd Motor failure)
Claim initialised by the shop and told week 29. Week 29 arrived and then told week 33. (16th Aug week)

18th Aug 2021 = her 4th Motor installed.
This time it was installed with brand new RCone (FLED28-15) new upgraded loom, new UPGRADED battery discharge connector and identical but new charging port plus the battery shim mod for good measure. Then it was all waterproofed with liquid insulator for good measure as always.

SUMMUM Carbon RR by the looks of it.

you could (almost) buy an Ebike for that sort of money ;)
Correcto. It was actually initial option to "upgrade" my current Rail but there's not much things that would change my riding dramatically and the new Bosch displays, software and ecosystem seem to be a little shite. Hopefully the Rail will get less beating when the other bike has to ride all the bikeparks (fun stuff) etc.

A pair of Continental TrailKing 29x2.6 (PureGrip) and a new drivedrain: Box Components Three Prime 9 X-Wide (9 speed, 12-50t), as well as a cheap Wheelset (Rodi Tryp 35 on XLC Evo Hubs).

I am currently considering if I should buy a new Fork (RS Revelation, Bomber Z2 - 130mm) or just save the money for a FS Bike in a year or two and stick to the ol' RS Recon.

Here is something you don't see every day on here, a throttle...I have been into motor assist bicycles for a long time and never owned one without one. I don't ride it at all just use it as a start out tool and a walk assist. But most of the ones made are cheap and clunky.

Got this one from a guy in Polska of all places and it is slim and sexy as well as ergonomically effective and plays well with my Grip Shifter.
