Hello
I've recently got one of these common 48V 1000W chinese kits and I'm wondering if I can change the controller.
It's this kit in particular: https://www.ebay.de/itm/elektrisch-E-Vorderrad-Umbausatz-48V-1000W-26-Rad-Fahrrad/162991246601?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
It's got a controller which says 48V 17A which would lead to 918W power. The thing is the motor is pretty loud and is creating a squeaking noise everytime it hits around 35 km/h. Goes away after like 1 second and comes always back when you reach 35 km/h. So that got me thinking whether or not I should get a sine wave controller, especially this one which comes with a LCD aswell: https://www.aliexpress.com/item/1200W-Brushless-Controller-DC-Sine-Wave-With-Hall-Sensors-And-Electric-Bicycle-36V-48V-LCD-Control/32798878157.html?spm=a2g0s.13010208.99999999.261.68513c00CWNAep
The thing is that that controller is rated for 35A which is double the amps which the original controller can handle so the question arises whether or not my motor can handle that much current? I'm pretty sure I'd have to change the wires from the motor to the controller because they look a little bit too thin for me.
Thanks in advance guys
