I started riding this year, and began with the clips. I fell over the first time out when I unclipped on the left at a stop and promptly leaned right. Scraped up my knee a bit, but it scared me so that it took another 8 months for me to get back on. I just finally got mad at myself because I had this great bike that I was too scared to ride. So, I got on, and rode loops in my neighborhood until I got to 6 miles. Last month I started riding with a local group and it has taken me 3 or 4 more rides to where I feel perfectly comfortable on my bike, clips and all.

Best of luck!
