Of course, if coating is the way forward then manufacturers should do it in production. However my point was could @Bearing Man do this when the motor is disassembled?
As circuit boards are impossible to buy new, would it not be a good idea whilst in there, to coat them in resin or similar?
I presume your mods are not suitable for the total immersion in the video above where a warm motor is suddenly cooled by a deep puddle or pool and a partial vacuum created...
"This starts slowly corroding the bearing race and ball bearings, this wears the ball bearings down until the bearing seals can no longer fit properly, allowing water to flood into the motor itself and eventually kill it!"
Would SS Bearings help or are they too soft to last?
Having read a lot about stature v crank length and being challenged in the leg dept, I checked the results of the various calculators to arrive at 152mm. It reduces the angular movement in hips and knees. The experts said that 165 is too long for shorter legged riders. I read that some ebike...

"When introducing the CX Gen4 it started with 75Nm max power and was later updated to 85Nm max power. The 85Nm update raised the support levels for all modes and gave us what we have today: 140% for Tour and 340% for Turbo with eMTB dynamically moving between 140% and 340%...
So this mode won't work if changing from 165 to 152mm cranks?

Bosch introduces software updates via a Bosch eBike dealer, who can program each bike to suit the preferred crank length. This adapts the progression curve in eMTB...
Hi
Bosch Gen 4 CX (non smart). While researching shorter cranks, I rang my LBS who said they can adjust upwards the torque to compensate! Good news for those who didn't know.
"Our components are splash-proof and therefore not intended for driving in heavy rain" Huum, Heavy Rain, gentle hose pipe jet, shallow puddle. QED Not fit for an MTB then! Or even a commuter bike!
@Bearing Man "All parts are available from us except the PCB" …Could you please clarify Pete, do you mean "all parts" and would these be 2nd hand from written off motors with corroded PCBs? i.e. to repair one customer's motor with a faulty sensor there has to be another customer's written off...
When I bought mine during lockdown, I assumed buying a Bosch powered EMTB was a sensible thing to do due to the company size and reputation.
I assumed the motors would be repairable.
I assumed that all parts would be available as they are for my Bosch Washing Machine
I assumed the 4th Generation...
