Here are two photos of our tandem with the Falco motor.
We are very happy with it. We have a loaded weight of around 370 pounds and the motor really helps on hills that we used to go up about 4mph in the granny gear. Now we can keep up with the rest of our group (and wait for most of them). We try not to used it too much on the flats as we want to get a good workout. However, it really helps in a headwind. Feel free to refer questions to me via my e-mail. Kent
