#3It does feel like this is such an untapped market. Think commuters, credit cart tourers, tourism around a spread out city. Something that is safer than a motorcycle and faster than a bike.

I would be more worried charging that huge home built battery pack. I'm sure OP knows what he's doing, but I wouldn't want to bet my house on it.

It’s only safer than a motorcycle if you have bike friendly infrastructure.

#6Respect: that's a beautiful pack.
I'm a total sucker for ebikes and built my first ebike around 2006, powered by 40lbs of lead acid motorcycle batteries.
I recently outfitted a trailer with a large battery made for an efoil (my other obsession) where the non-battery components went bad, the company went out of business, and "Hey, this would make a bitchin' ebike battery.
Here's me cruising around the Oregon back country with said setup last summer: https://imgur.com/a/lmvJSBW

#7In my city, travel habits and condition, I find I wish for more torque and lower speed. Every place I want to go has significant hills that the motor can't handle, and easing climbing hills is the main reason I want an ebike. My ebike's minimum speed for the motor is 15kph, which is ok by myself, but my family likes to go slower, so I have to go fully manual with them. When I look at ebike ads it feels like nobody else cares about these two areas of performance. When I talk to local ebike shops they are unprepared to talk about torque and minimum speed.

It was too early and a bit of a dangerous design, but the StokeMonkey was built for torque and worked great at low speeds.
Some pedicab folks in Austin used to use them.

high quality heavy 18650s weigh about 2 oz. 190 of them would weigh about 24 lbs. Throw in another 6-10 lbs for bms, wiring, casing and errata and it's not that bad.

The fact they are kind of slow and you can take them on trains helps compared with motorcycles.
