Sorry, late to the thread.
I bought an EW-38 almost 2 years ago
viewtopic.php?f=2&t=5760. Same as the 36 just slightly larger motors I believe. I'm 250 lbs and with new batteries it topped out at 17 MPH (27 KPH) but that didn't last long. It took me about 10 miles once but within about a month I wouldn't trust it to take me more than 3 miles or so. It was great for me as the store was just a couple miles away and I was allowed to drive it in the supermarket so I never had to leave it's comfort.
However, it's CoG is horrible (the 36 comes with wheelie bars though, I believe). Having the seat in the center position I put myself on my back on day 3 accelerating from a dead stop on level ground. So, no accelerating up to even a small curb or speed bump. Coast across or slow is fine but you will feel the jolt from the bump.
My hands being weak the E ABS Brakes worked great. I almost never had to use the hand brake for anything.
Tons of cool, albeit unneeded, extras like alarm (LOUD), remote start and something else I'm forgetting.
Anyway, enjoy the scooter if you go that way. I sold mine after a year to a nice lady for $700 and her eZip scooter for my daughter. That's about a $1000 hit for one years use. But it was a ton of fun and it either annoyed the old folks in the stores or they'd love it and stop me to ask about it.
