wow you do have lot question. I just got mine a week ago. I leave mine outside and with cover but take the battery inside with fireproof bag. https://www.amazon.com/gp/product/B09Q6FPGZ5/ref=ox_sc_act_title_8?smid=A2ALSQ2QMV8GYY&psc=1
hydraulic brake with big swell.
very good phone holder, https://www.amazon.com/dp/B094768FS5?psc=1&ref=ppx_yo2ov_dt_b_product_details
i would keep the pedal because late delay when throttling. if peddle will help a bit faster. just my 2 cent.
usually if the motor said 1000 watt should be nominal but Iam not sure either, hope you can get some answer.
Grab a firesak for ebike. More than enough room for both my surron and mx4. (1 bag for each battery)

Also I was looking into a fire cabinet just in case as well. Something like this...
Amazon.com : flammable storage cabinet
I do have this for my rc lipos, but the mx4 battery fit, but super tight fit and not an ideal bag, but cheap and amazon does free returns in case you don' t like. I'd go with one of the options above first though...
