Your pedal-power system has given my wife and me more pleasure than you will ever imagine. It has been a great way for us to enjoy the lakes and rivers in our area. Your craftsmanship is remarkable. Every time I take out our canoe, I renew my appreciation for what you have done. You certainly have added pleasure to a lot of people's lives.
Bicycle handlebars make steering much easier than steering a canoe.
Because leg muscles are usually stronger, we are able to pedal longer without fatigue. One person pedaling equals two people with paddles. On choppy waters, one person pedaling is slightly more efficient than two people with paddles. Having your hands free is a big advantage. We eat our lunch, fish, look through binoculars, and take pictures while pedaling.
