Hey folks, thanks for all the knowledge on this forum. I hope you aren't all sick of these newbie posts. I've been a bit obsessed with ebikes the last few weeks and I'm just looking for a sanity check before I drop some $$$.
I am basing my build on a Surly Pugsley fat bike. I want to be able to do 20 miles with 1000 ft of elevation gain/loss with some pedaling and hopefully 30+ mph top speed. So I'm thinking at least 1500w motor and 20ah battery,
I think I want a fwd hub motor, but I'm torn between a cheap kit vs a higher quality setup. I compared the 9C, DD45, 8T MAC, and a few others in the grin trip simulator and the MAC motor seems to be the most powerful and efficient. The higher torque of a geared hub also sounds nice for a heavy fat bike (maybe 230lb total with rider) as long as I can still hit 30mph with the 8T winding. But it would be half the cost if I went the cheap route....
Cheapest option:

https://www.aliexpress.com/item/4000026089791.html
352 battery + 347 motor kit = $699

599 battery + 537 motor kit + 136 shipping + 150 wheel build = $1,422
After all this research I'm leaning towards the cheaper setup. Thoughts?
Is it true that cheap Chinese cell batteries sometimes catch fire while charging?
Any other motors/batteries I should consider in that price range?
