Lyric Graffiti want more speed

[1Hotrodmd]

Hello All: I have a new to me Lyric graffiti (Not new Graffiti X) . it has dual 52V 20ah batteries. 1000W (2300W peak) Bafang gear hub motor. I have not looked at the OEM controller from Lyric. I see the watts stay about 1500 at 35-37 MPH. Could I get more speed out of the bike with a different Controller? (say Fardriver, Sabvoton, ASI BAC855, Etc.) if so what controller? or do i need a larger motor? if I need new motor and controller could i use the 52V Batteries? I would like to get to 45-50MPH at times and still go 40ish Mile range.

I am new to all this so excuse any stupid questions that don't apply......

Thanks.

For someone who wants to go fast, you sure picked a slow slug. The same batteries and power unit could get you a lot better performance if used on a real bike.

if you want to go 50 mph, use a motorcycle designed for that kind of speed. If you go 35 mph on 1500W, you'll need about 4200W to go 50 mph. You'll need at least twice as much battery for the same range. That's not a straightforward upgrade to what you have. Better to start over with a more suitable vehicle.
