On the other hand you might be better off walking just in case you bought the bike from a cheap place. It might fall apart. You never know... You would want a really good bike that can support your weight and that won't crash into anything. Walking may be better for some people if they want the excersise. But it might not be better if you have bad legs or run out of breath quickly.
