Walking and biking are great. I highly recommend trying one out and there are adult classes if you’d like help learning how to ride and operate a bicycle. A good, used bike with a bike rack can do wonders carrying things around. As a bonus they’re cheap to maintain and safe to work on, completely unlike wrenching underneath a heavy car.

Depending on your situation, you may want to consider a moped. They’re generally easy to get licensed for, often don’t require insurance, and costs about the same as a good e-bike. They require the same skills as riding a bike (knowing the road laws, understanding how to stop effectively, counter-leaning, etc). The bonus is you’ll be able to get up to speed on frontage and other roads that may not be safe to ride a pedal bike on (e.g. roads without any shoulder). Of course you can always do both, like starting with a pedal bike to get a feeling of how to ride a two-wheeled device.
