Hi there!
I got me this (used) G-Bike City- Electric Scooter
http://www.shopgbike.com/products/city/indigo.html
And it has the issue that it sometimes does not accelerate!
As if it is hesitating.
And when I turn the throttle a few times, it suddenly kicks in.
It has a controller which I could not find anything on (even tried Alibaba)
Brush intelligent motor controller jdk 404R

The bike came with a spare mystery box and I was suprised to see it next to the controller (small silver box above controller)

Could it be the throttle making the problems?

The batteries are totally OK, all same level and have much power.
Could it be a short or a broken connection somewhere?
Has anybody a schematic from these bikes? I checked the *** Controller Information Links *** but could not find anything on 48V 750W, but I guess they are all very similar, right?
I am totally new to these exiting scooter ebike things, but do know some electronics.
Also, I am totally blown away by some of the mods/posts on these pages, amazing!
Any help/info is very much appreciated,
