I am new to cycling. I bought a bike in March in order to do the MS 150. My husband has MS, and I wanted to support him and do something fun in the process. I knew nothing about cycling but being inactive and 40 lbs overweight, I thought that I needed a bike that was upright and comfortable. I bought a TREK 7000 hybrid. I really liked it when I was riding around my neighborhood, but after using it to go 150 miles in 2 days, I found out that it really was not the best decision. I had more people on the ride say that they couldn't believe that I was doing it on that kind of bike! I averaged around 10 mph the whole way. I am really hooked on cycling now, and am planning on training for another 150 in October. Any suggestions on a better bike to make the ride easier?
