Are These E-Bikes Legal in Melbourne?

Hello everyone! I'm considering purchasing an e-bike. However, I'm a bit concerned about the legality of e-bikes like the ones shown in the attached photo. The last thing I want is to invest in an e-bike and then get fined for using it. Could anyone with knowledge on this subject clarify whether these e-bikes are legal to use in Melbourne? Any advice or experiences you can share would be greatly appreciated!
