Dude , I don ' t know what to say except to say that only you can help yourself . I bike all the time , I ' m a serious biker . I ' ve got 3 bikes that are all awesome . A full suspension 29 er mtb I originally paid $ 1400 for , brand new , wicked deal . By far the most I ' ve ever spent on a bike . I ' ve got a hardtail singlespeed , $ 300 on the framefork that were a couple years old , some spare parts and new wheels maybe $ 200 more total . And a fixie I spent $ 250 on , new . I also ride large bikes . They aren ' t mythical beasts . I see bikes on kijiji in my area a few times a week that I could buy for 1200 $. Look around and you can find something used , but even if not , you ' ve got better options available new . Here ' s one , tiny bit above your budget at $ 400 , but it ' s 10 x the bike that walmart bike is
