Welcome to ES****Do this before your first post or now (it's retroactive)*****
Please go to the User Control Panel, select Profile, and then enter your city, state/province, and country into the Location field (country minimum) and save it. Once done, your location will appear in every post so you won't have people asking where you are ever again. This will help people help you. Example: Wylie, TX, USA. or just USA, but country as a minimum, and country is the most important. There are many cities with the same name all over the world. Without knowing what country you are in it's hard to make any recommendations. Thank you.

Welcome!

It's overpriced IMO. You can get they same in Aliexpress cheaper, and buying separately parts you will save money avoiding a very high duty taxes for such big order.

a 48V 12Ah battery won't run so bad in that kit, but just because that controller won't feed 1500W to that hub motor so far.

That controller looks like 500W max.

If you will buy in Aliexpress, I recommend to choose each component acording of your needs.
