I ride some places there is no cell phone service, so noone is going to come get me. The wife works when I am out on the bike, and it wouldn't fit in a Elanta anyway.
I lift weights 4x a week so I'm strong enough to do jobs like flipping my bike over for flats. Currently I'm curling 7 lb, I'm not a strong man. I weigh 150 lb summer. Touching my toes every other is also important. Watch a Pilates show like Margaret Richards; that's where I learned these exercises. You start losing muscle at age 55; I'm age 68. Upped to 7 lb this summer because 5 lb wasn't good enough for some jobs.
I lay the bike on grass, not concrete. Not a problem finding grass on my routes. Unplug & dismount the battery before doing this, and empty the panniers or baskets. I designed the mount for my display to flip down with two screws. The basket or aluminum frame I installed on the back keeps the rear fender from being damaged, also the rear light and rain cover. Last time I changed the tube I laid the bike upside down against a cable TV generator rather than lower the seat so the bike wouldn't fall over. Trees and road signs also work.
I carry wrenches for the axle nuts, two flat screwdrivers to pry the tire off, a schrader valve core cap from the auto supply, a pliers to pry back the takeup on the back and to wind it up installing, two tubes, a schwinn foot air pump. Two tubes because this ****ese garbage is all we can buy. One new one split immediately one time, I had to push the bike 6 miles. Tie wraps and a diagonal cutter to remove and reinstall the rear axle wiring.
I have a tube with a split in it that doesn't require removing the rear tire to get it on. I bought at at meiers discount store. I don't know if it works yet.
I removed the thin tire from the power wheel that came with it and replaced it with a thick Kenda that shouldn't go flat till the tread wears off. That should be enough at-home practice. Last flat was from a split cord off road tire from a $10 mountain bike. Don't use tires over 6 years old, like the NHSTA suggests.
