You can get two types they refer to as either full fat or half fat, that Giant looks like a full fat bike but as it's a hardtail it doesn't matter as much as you've not got the extra weight from the rear suspension to deal with.
Can ask my lad what the motors are like as he works with ebikes a lot, that would be the deciding factor for me or can see what he'd recommend based on your budget, definitely don't want to go full sus?
