Controllers don't fry for nothing, and it's very difficult to fry them. Why do you think it's fried? What did you do to it?

Is it a 15A controller?
Why did the mosfet blow.
Does your present controller give enough power for your needs.
What size (capacity) and voltage battery do you have?

When we know the answers to these questions, we can give appropriate advice for a replacement.

My old controller left new right

So, 36v 15A.

Two more questions because I previously made assumtions: I'm assuming using that you have an LCD of some sort. You know that most LCDs are specific to the controller? Which one did you get with the new controller?

I think we need to take a step back. Can you show exactly what bike it is and can you show the listing for the new controller? Why did you buy a bigger one?

The controller was supposed to be same size from his listing
But when it came it was a lot bigger

OK, some progress. It looks like that controller doesn’t fit. It's pretty crappy anyway and it has the old three speed switch, that's useless, instead of a control panel. That picture of the bike seems to show an LCD. What do you actually have.

If got it working during self leaning, you should congratulate yourself because most people wouldn't figure out how to switch it on. It should be OK for testing, but I wouldn't use it for riding unless you're really strapped for cash. That's if you can figure out where to put it.

I'm still finding it difficult to recommend anything because I don't understand what you're trying to achieve. Do you just want the bike the same as it was before or are you wanting more power or speed, or do you want a better control system that makes the bike better to ride.

Basically brought it to get it up and usable
Mainly for fishing and back n to work on nice warm days
Emailed ancheer but not had any reply as yet

Even just a link to a controller that will work with pedal assist

 

[saneagle]

All controllers for sensored motors should work, but they have different ways they deal with pedal assist.

I got interrupted doing the above post. You can get a three level controller with LED panel. Note that they've got their wiring notation a bit mixed up:
