Wish I'd had one before retirement.
I am a 60 year old recreational cyclist. My main cycle journey is 14 miles once a week after seeing friends where I used to live. It used to take 75 minutes, it is now an easy 45. Other journeys are also quicker and easier. I have not attached the throttle and so when I stop pedaling, the motor stops. This means I still get enough exercise to keep the pounds down and have my weekend beers. I previously rode to work 10 miles away 2 or 3 days a week. Can only dream of how much time would this wheel have saved?
