A year ago, I was 210 lbs and if I lied about my height .. 5'8" too , but it never occurred to me that a bike might not support my weight. Wishful thinking? I bought a (light to me) GT hybrid at Performance Bike, and that's when we noticed the e-bikes in the corner. An e-bike for my wife so she would ride more often, and then one for me to keep up with her. Now there's no room in the garage for my car. Twelve months later, I've lost 18 pounds, in part due to more interest in biking.
I alternate between an ebike and my GT, and when I ride the e-bikes, I want it to be exercise, so I always put in some pedal effort. Whatever gets you out and motivated for exercise is good.
