Because I am a life long cyclist. Most years I would cycle more than 10,000 miles. I love cycling. Then I became crippled by Rheumatoid arthritis. I was very depressed could no longer ride my bike. My father, also a lifelong cyclist, at 80 years of age decided to try an electric bike after bad experiences with 3 cheap Chinese bikes he bought a better one and fell in love with it. He could now do some of the rides he was no longer physically able to do. I thought that maybe O.K for me so borrowed his bike. It was fantastic, but I could not afford to buy one of the latest new bikes. However through reading this forum I decided on a secondhand Powabyke. Eventually found a shopper on Ebay for £180 modified it with bits I had in the garage. It runs like a dream and I am happy and back on 2 wheels.
