Bagi Bike Controler Problem!

I have a question, I have a Bagi folding bike that the display stopped working. So I bought a new one, and it didn't work either. Then I moved on to the wiring, only finding that the wring to the headlight was broken and nothing else.

This problem started back in Dec. I've been trying to get a controller from Bagi Bike from the start, and they keep telling me that when they come into Miami Fla. They will see if they can find me one that will work with the bike because they stopped using the one that came with the bike.

Here is a photo of the controller. I'm now running a 48-volt battery.

I don't know that much about Ebikes regarding what will work with a Bafang C961 display and a 48-volt battery.

Any help would be deeply appreciated.




Thanks Rick

Everything is from the manufacturer and that is my problem. They are telling me they stopped using the controller that came with the bike and keep telling me that when they come into Miami they will see if they can find an older controller!

So the problem is I need a controller that will work.with the wiring harness and a 48 volt battery!

I'm a bit confused here, that controller is 36V. But you have a 48V battery.
Did you upgrade your battery to 48V?
In that case, you should be looking for a 48V controller.

That controller you just posted, says 36V 15A, which is 540W.

I just went on the Bakcou website and the bike you posted has 1200W of power with 48V battery, which means, it has 25A controller.

36V 15A and 48V 25A aren't even close.. are you thinking about upgrading your controller?

It just doesn't make sense how you have 48V battery but the controller you posted is 36V.

Here is what happened I was sold the 48 volt battery after the 36 volt battery went bad from not being charged for three months while I WAS BACK AT MY HOME IN VEGAS and the bike was left in FLA.

When I bought the new battery they reset the display saying that was all that needed to be done! The bike ran okay for a while then one day after riding in a downpour the display went blank!

The display had condensation in it so I bought a new one and it wouldn't come on! I started working with Bagi bike and was told that they had change controllers. They said that when they came into Miami they would look at the controller and see if their new ones would work. I missed them one time when I had to go back to Vegas. This problem has been going on since Dec and I used the bike to get to the beach to metal detect because of what they charge for parking in Ft Lauderdale Fla.

So now I'm trying to fix the problem myself and match up a controller that will work with the wiring harness and the battery! The bike uses a Bafang C961 display!
