I recently bought this motor and am slowly installing it.

I want to do everything right (at least approximately). I found a topic about cooling, and I already bought some copper braid.
Also I have read a lot - that this model is vulnerable to water.
Because with a battery it is much easier - to buy or sew a waterproof cape, which costs $5. You can also treat the cable connectors with a special grease for electrical contacts or even use a heat-shrink tube (there are options with "glue" inside, which is sealed hermetically)....
But, colleagues, how do you protect the motor itself (and the controller inside) when riding in the rain and through puddles, etc.?
 
Never use a pressure washer /hose to clean your bike, a stiff and a soft bristled hand brush ala brush and pan and warm soapy water is all you need to clean even if it takes 10 minutes longer..

If you crack the case to open up reseal with rtv gasket compound or a poormans option like blue thread lock or b/room silicone.

as is your motor should be splash proof against rain and puddle splashes, But greaseless bearings due to pressure washing is the biggest gotcha that im aware of..
 
i would say this motor is not vulnerable to water, i had tsdz2 for a while and water never did anything to the motor,(i drove one time in extreme rain and still good) just make sure battery connections are dry and dont install the battery backwards (like some do)
 
I use passive waterproofing. You go on a ride and when bike is covered with mud you ride through forest. Whatever sticks to your motor sticks to your motor. Then another layer of mud and so on. Who is washing a bike? Pfff

I always wash my bike, (especially since I've been forced to keep it in my apartment for the last few years). But even when I had an enduro bike, it was always washed slightly after riding)) Also, 90% of my riding is on e-bike - paths, roads, and sidewalks (in a clean EUcity), so the bike doesn't get very dirty.

I just found a few comments on YouTube that the TSDZ2 burned out after riding in heavy rain.
I didn't find a relevant topic here on the forum, so I decided to create a new one.
p.s. the TSDZ8 on the photo better protected from water, as far as I know...But I didn't choose it because it's much heavier and larger than the 2B, and it also requires a bigger and heavier battery. Besides, my weight is close to 80kg, the 2B is more than enough for that.

I had some issues with rain, but that's because of user avoidable error with an xt60 connector which wasn't on it's own enough. Didn't want to tape it before because I wasn't sure if I were going to swap things around any time soon, but after those issues in heavy rain I resorted to a nice layer of electrical tape and no issues since. I would throw some heatshrink around it but I don't have anything big enough :(

My bike hasn't looked like the pic above from @Az in quite some time ( thanks to the trailcrew for replacing more and more of the soft clay with granulate so we can actually ride bikes instead of plow mud ).

Agree on the pressure washer, avoid at all costs. I use a soft brush to remove the caked up mud, and then a bucket with a sponge and some soft rags.

When bike does look like above pic, carwash stations also have buckets.. I mean, I live on the 5th floor and my bike goes in my apartment, I would get kicked out of the building eventually if I drove my bike through the elevator and hallway like that 😇
