I used to pedal bike to work, 4 miles. When I got there I was sweaty and had to clean up (there is no shower at work). It would take about an hour for my mental energy level to return to adequate level to perform my focus intensive work. At my age and fitness level, I could only ride 2 -3 days a week.
The electric bike was the perfect solution. I can now bike everyday. I love being outside. I can pedal if I feel like it, ride if I don't. I arrive at work fresh enough and with enough energy to start work immediately.
I would never bike after hours or weekends, now I go on 20+ mile treks exploring the many bike trails.
