Someone Left the Bike Out In the Rain

I don't think that I can take it....

My bafang ultra is IP65 but I noticed gaps where the rubber grommet is supposed to seal the cables going into the motor housing. I filled the voids with silicone so water should not be able to find it's way in. I don't know how it could have this rating when you can actually see where water would get in. Speed controller is inside the motor and potted

If you've ever opened up the motor you would see that rain and/or spray would not get thru there. Also that rubber grommet ends up in the motor mount and not exposed directly to the elements.
IP65 does not protect against submersion.

If water is going to get around anything first it's at the crank shafts where it's just a bearing and grease.

IMO, with the pace of innovation/changes/upgrades in the ebike market and the proprietary designs of everything involved, you kind of have to look at the standards as a starting point to safety/performance, not a guarantee. Even a specific bike that gets certifications is likely to run into some production changes that compromise something… rubber grommets, frame manufacturing changes… you name it.

I don’t mean to be a cynic, but with such little standardization in the business, it’s no surprise to me that things are where they are.

The last time I opened the Fat Boy's motor I sealed everything with silicone gasket sealant. Water still got in. I suspect that @Gionnirocket is correct about the cranks/BB.

I have a perfect Gray-Poop-On bike here for him. It is all chrome and leather owned by a gay guy in the town of Sonoma. It looks totally classic and space age from 1962 but it is mint. It gleems and looks like an immaculate bike that JFK would ride to a picnic on the Vineyard. The tan walls match the leather and it has a polished 8-Alfine hub and deep aero rims. It is chrome and tan. A two chord White Stripes song.

Aren't the crankshaft seals double lipped rubber? Should do a decent job

Don't give me no lip.

I use double lipped rubbers... for my pleasure

I sometimes make Frankenstein bikes. That tight one doing her yoga vanished.

Barracudas like salt water. They are like salt water pike or muskies that hunt baby ducks.

Pedal, I am just curious, but did you build out that Fat Boy with the Tongsheng motor? Wondering how difficult that was and what snags you might’ve run into. Could be a future project for moi… I love the idea. Also, if so, in retrospect, would you go with a different kit for one?

@Chazmo, Get the DM02 with a 110mm wide bottom bracket. And go for the T154 display. Put a rubber bushing between the motor and down tube and lever the motor forward and up against the down tube as you tighten the lockring with a ton of locktight. You could order from me with support in English. See Google Maps for photos and reviews. That fat bike is a TSDZ2, before the 'B' version. Knowing what I know now, I would have done things differently. I have come a long way since the pandemic. It required a ecentric American to British BB adaptor.

Superb. That is really cool, Pedal…. THANKS!!

 

[DDBB]

No doubt, that's a cool looking bike

See how I ran the wire to the display through the frame? I was able to up the amps but not too much to blow it up or overheat. The same time I did that one, I did this fat BBS02. Guess how I made the connectors disappear? We have six beer gardens in town and the guy uses the chopper to visit all of them in a day without driving a car.

Man, I have a love/hate relationship with Permatex adhesive sealant. It is cooler and raining today so I have on brand new Livi's that would typically last me five years. Permatex has a cursed way of magically flying across a room to wreck pants or shorts. There is no way to get it out. Yes, it keeps out water, but at what price?
