I have a Sun tricycle. My son bought for me four years when I was casted for 13 weeks. He knew I'd be stir crazy if I couldn't go walking. I was at the bike shop today. They only had a large Specialized in my price range. The young man and I both agreed that I needed a small frame, so that is settled. I have found a Schwinn low entry one online, but I'd have to drive 75 miles to get it. I doubt if one will fit in my car.
