I bought a 1200 watt ebikeling rear wheel and a unit pack power 52 volt 20 amp. I saw a video suggesting I can turn up the voltage on the controller to take advantage of the battery I have. however. the controller doesn't let me adjust it. I've asked the co. no response yet. can someone explain what options are there. and if there's away to squeeze some more speed. right now I can go. 32 mph. I weigh 150. my bike is prolly 75 total. am I looking for info. from getting a better controller
or. jail break this one. ? anything. I'm happy going 32 . but wouldn't mind going 37 if possible.
 
''Turning up the voltage on Controller'' means that you can apply more voltage on the battery side. But in order to do that you would need a higher Voltage battery.

But a typical 48V Brushless Controller can only handle a 52V Battery (58.8V fully charged). So if you want more speed you would have to buy a 60V Battery and a 60V Controller.

There is also another way. Controllers exist that can do ''Flux Weakening'' or 120% ''Overspeed'' as some chinese sellers call it. This will strain your existing battery a bit by pulling more amps at those extra 20% above 100% speed.

This Controller for instance goes up to 84V but also has the 120% Speed function.
