As an owner of a Bosch powered bike this was helpful and interesting. When I bought mine I asked about motor servicing and the dealer said they don't need it. I'm sure at some point it may need something like this if I still have it and good to know there are decent mechanics around that can. Thanks again Dave.

[@TheYorkshireBikeMechanic]

[@twinshock175]

I think if for this customer on his budget, only the outboard bearing needed attention. I would have repacked the outboard bearings and seals with marine grease to waterproof the exterior sides, done this in prep to my past enduro and mototrials motorcycles, as they last way longer than factory grease, mind you this bike would never see that harsh environment! First time watching your channel and interested to see inside the e-motor, clear and precise explanations and video, well done.

[@boryscholewinski4370]

Such a lovely manner of narrating.

[@TringmotionCoUk]

Always good to watch how someone else does it 😆. Personally, I always use the side panel, as the nylon always seems a bit on the worn side when I need to do this. I have also had a machinist make me a press tool for the NDS bearing! I think our only real difference of approach is I put the bash guard back on and use a hub puller (just a cheap 5 ton hydraulic) to extract the side plate.

[@TheYorkshireBikeMechanic]

I own a Bosch Gen.2 Ebike since 2015. I have replaced 2 motors already on 7k, 8k under warranty. So free of change for me. Now 3rd motor reached 10k and it sounds same as yours, so I am currently thinking about 3 scenarios: repair myself (costs 130 Euro for Service Kit), repair in the shop (unknown costs) or replace motor (600 Euro). I wanna keep my bike, so even if it comes to worth 600 Euro, I will pay it. Thanks for the video, it is really helpful.

Firstly….. nice workshop. On to the motor, I’m a bit sceptical as to how well sealed these mid dive units are. Not particularly impressed by the amount of plastic gears in there either. Given the price for these units I feel you deserve more for your money. Given the amount of surface mount electronics inside they certainly need to be sealed better.

[@TheYorkshireBikeMechanic]

Hi, thanks for watching and your comment.

[@philrichmond5919]

What don’t you like about plastic gears? Often they’re more suitable than metal, run quieter, are self lubricating, are aramid fibre reinforced for strength and are cost effective. Metal gears need lubricant and if that gets contaminated you’ll have a grinding medium that’ll wear the gears faster. Bosch know what they’re doing.

[@g-atti]

I aggree that the plastic gears are quieter. But who was that design genius, who put the circuit board together with the greasy mechanical stuff? :D

[@carstenwangnick3388]

Excellent video! But the noise proof at the end by simply turning the cranks is not representative for the daily use, because the motor is not in operation, since the chain is off. In reality with working motor support the noise is significantly louder

Hi, Thanks for watching and your comments, the issue with this motor was the main drive side bearing, that was the noisy culprit, the motor noise would have masked how quiet the bearing was after replacement.
