@EverydayMoggie asks:
E-bike motors are not very reliable; it seems that about 25% of them fail pretty quickly.
Q6. If you have an e-bike, have you had trouble with the motor?

@ascentale @EverydayMoggie @bikenite A6. I am happy with my Bosch CX motor plus 2x 500Wh batteries (1000 Wh in total available in parallel). Running for almost 5 years now without any issues at all, but only around 5000 km so far. My weight is a bit heavy, so my e-bike has to provide continous support.
I am having problems with my Enviolo NuVinci because I feel that the gear ratio is no longer the same as it was originally.

A6: The original Bosch Performance CX 4 of my 2022 Bike failed after roughly 6500km. The internal clutch was faulty.
To my knowledge the Bosch motors are never repaired by Bosch, only replaced.
There are 3rd party shops that do attempt repairs.
The motor was replaced on warranty and has been running 13000km since then.
Then again, everything in this ebike wears out quickly.
@ascentale @EverydayMoggie @bikenite A6: had an ebike for a few months, a second hand longtail with an AliExpress front hub motor. The unreliable part was the display on the handlebars, it was not waterproof.
I bought a replacement for ~$20, took it to work and sprayed the insides with conformal coating then filled the voids with acid-free silicone and closed it back up. That may have helped, it may not. But I never had more problems :)
@ascentale @EverydayMoggie @bikenite #BikeNite A6. My Rad Power Bikes RadMission has been completely reliable since I acquired it new in late May 2022. It has a 500 W rear hub motor made by a Chinese manufacturer I cannot identify. I live in a hilly area and regularly subject it to maximum loads.
@ascentale @EverydayMoggie @bikenite A6)
Bosch active line 2nd gen / 2015: re-greased the gears at approx. 15000km as there was noticeable gear noise. No issues after that. Swapped to a refurbished 2nd gen performance line motor at 27000km as I had to remove the motor anyways to replace the battery cable that was corroded due to salt water 2 years earlier.
The original battery is at approx 22000km and ~10 years and one battery cell has low capacity now (bike switches off at approx 50% indicated charge).
Had a BMS board failure with a battery that was just 3 years old (Fagor Schottky 2A 60V used in the 5V supply of the CAN controller, BMS chip and microcontroller). Fixed this myself (<10 bucks instead of ~700 bucks for a new battery).
No "professional Bosch certified bike shop" would've done what I did to keep it running/extend its useful life. They just swap components and want a lot of money for it and if its old just buy a new bike....
@ascentale @EverydayMoggie @bikenite #BikeNite A6: I have two e-bikes, one is a bio bike that got an friction wheel based e-assist system named Velospeeder in summer 2023. Had quite some smaller issues, but never with the engines itself: broken pedal sensor cable, worn down rim, worn down friction rings, a mounting that worked loose, …
The other one is the Brompton Electric G-Line with ex-works e-Motiq rear hub motor. The only issues so far were contact problems between battery and frame.
@EverydayMoggie @bikenite A6. I don't use e-bikes a lot but thankfully have had no problems with the motor. There do appear to be some small problems with the battery system that probably have something to do with not charging it often enough.
@ascentale @EverydayMoggie @bikenite some battery chemistries will die quickest when charged from 80% to 100%.
Unfortunately most bike batteries are very hard to short charge, and the maximum range isn't such overkill that most want to start every ride/day with a full battery.
@LovesTha @ascentale @EverydayMoggie @bikenite The other question is: do you live somewhere cold enough for your bike to get below freezing? Good batteries will have controllers that sense it's too cold and refuse to charge because that _will_ damage the battery.
@moira @LovesTha @ascentale @EverydayMoggie @bikenite Good point. My advice is to charge inside the house during winter. I also take my batteries into the house in winter, even if I don't need to charge them.
@moira @LovesTha @ascentale @EverydayMoggie @bikenite
#BikeNite If my garage temperature gets below freezing, I'll bring my ebike into the house to charge it.
@moira @LovesTha @ascentale @EverydayMoggie @bikenite
I don't have an e-bike, but that definitely happens with my bicycle cameras. Too cold and they shut off.
@moira @ascentale @EverydayMoggie @bikenite I don't, and I question why people do ;)
@LovesTha @moira @ascentale @EverydayMoggie @bikenite Not all of us live in sun state California. 😉
@LovesTha @ascentale @EverydayMoggie @bikenite Some of us like it cold, that's why. ^_^
(Some of us come with what I call "the complete cold weather package" which means we'll shovel snow in shorts but literally pass out in temperatures Southerners consider "comfy." We have a ... definitely more northern habitable band. 😁 )
@moira @ascentale @EverydayMoggie @bikenite I'm a 5~25C type. It's a range well suited to a 37C body
