A2B Hybrid - upgrade

[FLAXinFLY]

Hi everybody.
I have been looking for some information on how to upgrade my A2B hybrid bike, but there is not much about it (or I haven't been able to find it) and it's quite confusing.

I'd like to increase the maximum speed of the bike.

Should I just change the controller or also the battery?
And which controller and battery (if so) should I go for?

Hi blueprius
first of all thanks a lot. I have read it, but it's not exactly what I need. I need something simpler and straightforward.

that thread explains how he tested the controller to work up to 56v, I believe he upgraded the pack to a 48v lifepo4 57v HOC, doesn't get much simpler upgrade for faster speed
