Thank you for the reply and the links. From what I've read it sounds like the only way for me to test is to have an electric motor repair place check it out. Do you know what the implications would be of connecting a new controller to a motor with burnt windings? I suppose what I'm asking is if...

Well with weather starting to warm up, I'm finally back to trying to diagnose what went wrong with my BBS02 motor. I'm becoming more convinced the issue I experienced is related to water getting into the BBS02 rotor and coil. Here are a couple pictures. The first is of the coil. The second is...

Well since my last post my new controller has arrived. I have not yet installed. Instead I'm taking some time to try and figure out what happened to the first controller. Here is a picture of the same controller with much of the black soot cleaned off (left). The image on the right is of the...

Thanks for the reply. Your tip about checking the motor windings makes sense. I have the motor apart and wondering if there is anything I can do over and above a visual inspection of the windings. Perhaps check resistance of the coils? Any suggestions? I think I will seal the motor and...

Does anyone know if there is a dedicated forum here on Endless-sphere (or elsewhere) where frame builders hang out? I'm considering building a custom ebike steel frame and looking to connect with others who have either done it or are in the process of building.

I don't disagree with you. Unfortunately my experience has not been great with the first controller. If the second controller I've ordered is more durable and reliable, I'll definitely stick with it. If not I'll be hard pressed to buy another. At $200 a pop to replace the controller here in...

BYTW thanks for including the link to the article. I had come across the article while researching what could have happened to my controller. It was because of what I read in the article that I decided to give it another go and buy a replacement controller from EM3ev.

Yeah, I think the fried board is the result of an inferior electrical component and not due to water. The blackened area of the board is on the underside of the controller and was completely sealed with the potting material. In the picture you can see how I was able to peel it off in one piece...

Does anyone know if other controllers have been used successfully with the BBSXX drives? I'm wondering how well the Grin PhaseRunner would work as an alternative. The BBS02 was my first foray into ebikes and it was great up until the circuit board fried. If possible, I think I'd like to run...

Hello, not sure how I add my purchase to the survey results, however here is my story. Purchased the Bafang BBS02 48v 750w kit from eLife Bike through an Ebay ad in April 2015. Date stamp on the drive indicated it was manufactured in January 2015. Item was shipped from China via FedEx. The...

Thanks for the reply and the water proofing tip. Are you suggesting spraying the outer housing with that stuff or the inside of the controller? I am thinking of adding a layer of silicone on top of the potting material on the controller, plugging all holes and sealing the housing with RV gasket...

This is a very interesting idea. I have just had the controller in my BBS02 burn up while my bike was sitting in the garage. Display was turned off, however battery pack was turned on. Digging out the controller I discovered that something on the board seriously burned up (water perhaps)...

Hello everyone, I have had a BBS02 750 watt drive on my bike for a little over a year. Code on the housing indicates it was manufactured in January 2015. It is the 25 amp version with 9 mosfets. Total mileage on the motor/controller was just over 2000 km. A few days ago I washed the bike...
