I have just started Body BIke classes at the gym. Cycling has been something I've wanted to get into for years. I'm limited to classes I can get to, due to work, care, and DH working shift work. So am looking for a bike, and either a bike trailer or bike seat. Any advice? Thinking a trailer. Also any advice on what bike - I've been looking into hybrid bikes. But not sure. So throw your experience and advice at me.
