So, where I live I'm too scared it would grow legs when I'm in store shopping. What do you use for a lock/security? Or are you in one of those places people act right?
A Kryptonite Evolution U lock through your frame, and locking wheel skewers is sufficient in most cases. Yes, any lock can be cut or picked, but picking them isn't as easy as LPL makes it look, and cutting one draws attention. If you're in a moderate crime area, I wouldn't leave a bike locked up over night, but otherwise you'll probably be fine.
No offense, but where do you live? Living somewhere reasonably flat (anywhere in the midwest, for instance) makes a cargo bike much more reasonable. The town I live in is at 1500'; my home is at 3000'. That's a 1500' elevation difference over the 10 mile or so drive, which is not insignificant. Especially since most of the climb takes place over about a 3 mile stretch.
Somewhere pretty hilly. The bike is electric so helps with the hills a lot. I'm not light and even with cargo it can maintain 15kmh up 20% hills with me pedaling. It does hit the battery: I get about 30km on a full charge if I'm using max assist on hilly terrain. Can get a lot more if I use eco mode on flatter ground
