I want to increase the top speed of my China made ebike, it tops at 30 kph, targeting around 45-50KPH, specs is 48v battery, 500 watts controller and 48v hub rated at 350 watts. I am getting different info from the web.
Option 1 Upgrade my battery to 60v, which means changing the controller to higher voltage/higher wattage and keep the hub as it can "supposedly" handle 60v
Option 2. Upgrade controller only to a higher wattage

Not confident with option one, but does changing the controller to a higher wattage one be a good option?
 
350 w motors are just not suitable for hot-rodding.

If you wanted 50 KPH, you shoulda got a 1000-1500W DD hub, THEN run higher voltage thru it.
