Excellent post Barrio, at Performance Line Bearings, we have been packing the crank bearings and main motor bearing for some time now and although the original Bosch silicone grease helped for a while, it picked up dirt and disappeared over time. The new Bosch "green" grease is definitely an...

Although you can't buy parts for these motors, I have several motor ICU's (PCB boards) but can't help with the LCD? Contact me through my website if your friend wants to try my ICU's

For those who have asked, we have delivered, and what a specimen we found to overhaul this time!

Do you own a boat? :D

You would be more than welcome to pop in, we could put the Bosch diagnostics on your bike and see what has been going on? Delete your error codes and update the battery software and just have a general look over the electrics. Just contact me at peter.collard@performancelinebearings.com if you...

If you set the crank length to less than 165mm and run 170 -175mm it's lovely! The motor adds power low down to compensate for you trying to set off with short cranks. So, when you have longer cranks fitted it feels like a nice shove of torque, each time you shift gear. More noticeable when...

A PW or PW-X motor will fill with water if submerged for any length of time. The main issue with the Yamaha motor is that the circuit board is located at the bottom of the motor, once this has been submerged, it's usually game over!

If you tighten the battery holder and it does not fix the issue. We would be happy to look at the bike for you if you can get it to Hampshire? performancelinebearings.com

Thanks Bear, today we just finished filming a complete Brose overhaul and we are about to do a set of short videos to point out some of the hints and tips we have picked up over the last year or so.

Update: As we are now fully Bosch qualified, we can set the required motor perimeters and software updates.

As it says on my site, I ask people to state wheel size when ordering. I have 27.5 and 29" in stock.

Not from Bosch, but I currently have zero mile motors in stock, they are new but may have slight cosmetic damage (hence the price)

At Performance Line Bearings, we are now the UK supplier for "MudStop". The Bosch bearing cover developed by Velo Lab. This is a product that has been proven to greatly extend the useful life of the Bosch main motor bearing. We have also added complete Bosch motors to our site. These currently...

Thank you so much for your support and comments guys. We really need feedback like this to keep going. Big thumbs up.

Excellent feedback, thank you Barrio. I have found a very similar grease now and there is 100ml in the tube rather than the 20ml from Bosch. I am doing some tests to ensure it is as good if not better and if I'm happy, then it will be on the site soon. :)

All prices include VAT. Sorry, I will amend my site to make it clearer.

Yes. The balls inside the bearing are a little larger and less of them, so the bearing takes a little longer to fail completely, but they do fail.

You are all probably aware of the service repair kit Bosch released recently. Designed to replace all the bearings and plastic gears on the right-hand side of the motor. What we have found is these bearings usually fail due to water ingress. The problem is, water also gets in through the...

Excellent advise Pete! I have now seen so many motors where the damage has been extensive because the warning signs were ignored! If your motor starts getting noisy, don't ignore it!! Also, stop fitting MAX bearings! They are the wrong bearings for this application. Use this one...
