I got excited about the product specially because it does not require to buy a new bike. I didn't exactly know much about bikes, but with a little patience and help of YouTube, I finished installing it in about 2-3 hours. First time, I used it to go around the neighborhood. Since then, I used it to do some grocery shopping and go to meetings in longer distances. The furthest distance I ever went with a fully charged battery on full power with no throttle was 14 miles and I didn't run out. I am not very much in shape so I need assistance going uphill. With swytch bike, I can now make more meetings on bike and burn less fossil fuels. Also, it helps me to do more exercise by bike. It is a sweet upgrade to my life style.
