How to choose an ebike?

Lately, I've been rethinking my daily commute. I drive most of the time, but between traffic, parking costs, and rising gas prices, it's been such a hassle. I've been exploring eBikes, and I came across ENGWE MapFour here. I Googled it and honestly, I love the design—it's super stylish, has a 100 km range, 80 Nm torque, and even GPS tracking!

My commute is about 6 miles each way, mostly city streets with a few small hills (nothing too steep). I'm looking for something efficient and stylish that won't feel like a workout every time I ride. Do you think a lightweight eBike like this would make a big difference? Also, is carbon fiber worth the hype? I'm new to this whole eBike thing, so I'd love some advice from people who've been riding longer! Thank you in advance.
