I went to a local bike shop last week and looked at a Downtube Nova. I asked the salesman if the bike would be a good fit for me. I'm 5'11 and weigh 200 lbs and want a bike that I can use for cruising around town and the occasional dirt bike trail. Well he basically told me that I was too tall for the bike and my weight was right at the bike's limit. He said the bike is really made for people no taller than 5' 8" and that I was better off purchasing the Downtube 9fs. He also said that he knew someone who was my height that broke the frame where the seat post gets adjusted because the pole was lifted too high. He said the seat post is really only supposed to be adjusted like halfway to properly support the weight of a rider.
Does this make sense? I want a foldable bike with 20" wheels that's lightweight and will support my height/weight but can be used on various surfaces. I can spend approximately 300-400. Can anyone suggest a good bike? Thanks!
