How can I run my e-bike wheel on AC power?
You can wire the + and - connections of the included controller to a power supply. Bear in mind that the current, which will be limited by the controller can initially be quite a lot higher than the rated current. A battery will tolerate that, but the switch mode supply you ink to may well limit or shut down when it sees that current, so you often need a large margin on rating the power supply.

Given that the battery's characteristics  - it has a finite internal resistance, and the supply will droop under load - will affect the performance of the motor, so if you're using the rig to evaluate available power, you're better either using the intended battery, or a supply that has matching characteristics.
