Thanks for the great post and pics.  My only comment is about the fitment of a 25A controller.  I just finished installing one and it fits just fine.  It might burn out the motor . . . only time will tell.  But fitment is not an issue.

Hi, I am waiting delivery  of my Fold X 2018 model 5PAS ,7Speed, 500 watt motor. Bike shipped same day I ordered it. I also ordered an aftermarket LCD, 25A Controller, Thumb Throttle, LCD extension cable and Hydraulic Disk Brakes. 

How is your motor holding up with the 25A controller? You mentioned it may burn out the motor so that s why I am asking.

Hi Guys, thanks for the continous feedback. Love that.

The more I read the more i understand...but still a lot to find out.

I own a fold (european). battery 48v14ah, Bafang 250W, stock controller 15A.

I was preparing my upgrade of the controller but...I think in my case it does not has sense.

After 10 months of use my fold offers between 630 w (max batt load) and 510 W to the motor.

Tension of the battery between 52 and 44 V.

I have found that with this battery (14ah new ...12.5 ah now) the new controller would not change the Wh that arrives to the motor.

I'm I wrong ??? can someone help me if this correct to discard (or not) the upgrade.

 

thanks in advance

Keep it.  Best thing I’ve ever done to my fold — I’m getting 750-800w to the motor!!  Then again I have an US model...not sure if that makes a difference?

Sorry for dropping the ball (I don’t visit this forum often anymore).  Battery is stock for the 500w 2017 model — 48V, 14aH I believe.

Thanks. It's useful even in this moment.
