Should I drive or bike to work? I'm going to start a job next summer as a sailing instructor. I've volunteered before and biked the 3.6&nbsp;mi (5.8&nbsp;km) commute a few times a day on a mountain bike I found trashed a year prior.

I'm thinking because I'll have my license by next summer I won't need a new bike, but also this bike is just fine. The bike just has a bent wheel that is a bit wobbly and the gears are wonky. Would I be saving money by getting a bike and using that, or is it worth the space and luxury to just use the car? (I already have a car I would use).

I was thinking of getting something like this, but with fenders and a suspension fork: https://www.rei.com/product/816068/novara-randonee-bike-2014

I am located on the east coast of the US.

It seems like everybody has a false impression that I'm a sports instructor or that this is hard work; it's not. Sailing can be hard work, don't get me wrong. But I'm in a motorboat following the kids around.
Health

Two decades ago I threw away my bike.  Admittedly it was worn, but I had that "I have a car, why do I need a bike?" thought.

After a long time in a sedentary desk job, I got back on a bike and started the return to a healthy weight and muscle tone.

Best to keep the habit of healthy exercise by doing plenty of it. 3.6 miles (5 km) is 15 minutes at a casual pace, or 10 minutes if you're making an effort.

Nowadays my car does 150 miles (225 km) in one year, while I did twentyfold that on a bike.
