I believe some are trying to give others confidence in explaining just how easy it is to fix a flat tire. The title of the thread gives me impression it's a situation where the rider needs to resolve the issue without help. I ride in areas where there's no cell coverage sometimes and it can be a long way from a friend, a hundred miles from a friend. Being ready and able to repair most issues offers peace of mind. I might be more anal retentive than most though.
We often see people new to ebikes post concerns about this issue. It really is one of those things many of us learned as children. As the old saying goes, it's just like riding a bike
You might have to carry something specific to the bike in question. The wheel might weigh a little more depending on the drive. And there are electronics and possibly hydraulic brakes on the handlebars to be careful of, if turning the bike upside down. It really isn't difficult though.
I've encouraged new owners in the past to do a test in the comfort of their driveway. I usually rotate my tires, once or twice a year. This makes a perfect test to successfully do a puncture repair except for the patch. The patching can be eliminated by carrying a new tube. Take the front tire and tube off the front rim and install on the rear rim, and vise-versa. This will help a new owner get familiar with their bike, instills confidence and is good practice for when you need new tires.
