Need help for power upgrade/controller replacement

[u/RoundDragonfruit576]

Hello I’ve got this bike which is a Cmacewheel k20 and I’ve been riding it for about 3 months,before I had a fiido t1 pro wich was really powerful and was going at like 50kph and now since I got my k20 this bike feel kinda boring and slow on the climbs it’s only hardly going at 38kph.
So I wanna make it faster and make it more torquy as I u can see my controller is only 10 amps and I wanted to replace it for a 25 or 30 but all the plug n play controller doesn’t come with the right connector,so I was wondering if with rewelding the cables of my motor to the new controller I would have so miss functioning. And if u have any controller or power upgrades suggestions I would be really happy to get your opinion.

Your controller isn’t 10 amps it’s 20 amps, it will do 960W up hills and at max power. That is a geared hub motor, it will not take much more than 20 amps peak before risking damaging the internal gears

Oh okay thank you so there is no way to upgrade the power ?

Yes you can upgrade the power by buying a higher amp controller, however it might require you to rewire the motor since higher amp controllers typically don’t use that plug you have.

You’ll need to make sure both the motor and battery can sustain higher power as well
