Hello All. I was thinking of getting an exercise bike, but now thinking it would be better to buy a regular bike and get an indoor trainer. Your thoughts? I do live in a warm climate, Phoenix. But gets real hot in the summer. I read somewhere that Trek bikes have a weight limit of 300 pounds. So would you agree that an FX 2.0 will be ok for me? I know the 3.0 would be better, but cost is an issue. Thanks!
