Is ebike commuting extending my life?

It has quantitatively improved my cardiovascular system, so it is probably extending my life.

Six months ago, I got a state ebike voucher and committed to making good on the government's $. I started multi-modal commuting ebike => train => ebike. About 10 1/2 miles of riding a day on a low-powered 350W, pedal-assist-only ebike. It has pretty much replaced my car for commuting and errands. I just turned 61 last week, and had a heart attack at 49.

Also, coincidentally, six months ago my cardiologist ordered an echocardiogram, which showed that my ejection fraction was just below the normal range of 50% to 70%; that's the % of blood in your heart that it expels with each beat. We scheduled a 6-month follow-up to see if that was getting worse, staying the same, or getting better.

The results came in today, and I'm happy to see that it's gotten better over the past 6 months and almost 1000 miles on the ebike. It has physically changed my life and health.

Manual bikes are great for some, and ebikes are great for some. Whatever gets people off the couch and pedaling!

P.S. I just upgraded from my starter ebike to a same-power, quicker, all-carbon "sport commuter" ebike, rebuilt from flat bars to drops. It's more fun, so I'm riding harder with an even more intense cardio workout while shortening my commute. So I'm going to start skipping the train and riding the whole 26 miles to work at least once a week.
