If you're trolling: lmao

If you're serious:, please find a builder or shop to complete this build. I feel you'll have a much better experience than trying to fumble your way though this

there would be no brake to put on the disc then

If the caliper is on one side, you put the wheel on so the rotor goes between the calipers.

probably in respect to the motor yes

No offense, but if you're unable to troubleshoot something this simple on your own you might be better off taking it to a shop/builder.

You probably put the wheel in backwards, or have the motor wired backwards or a missing option somewhere if you put it in in the direction it spins.

yyeah but there is kind of only one way i can put it in with the brake screws and all being on only one side of the fork

Wire the motor in reverse, if it is a brushed motor (2 wires red and black) just revers them.

If it is a brushless motor (3 wires usually blue yellow and green) then swap 2 of the 3 wires (example, blue to blue, then yellow to green and green to yellow) If it has a hall position sensor, also swap the same pair of wires on that.

Or some controllers may have a reverse function on them.

how do i do that? it's a generic chinese brushless motor, only one connector going from the motor to the controller
